Introduction: Neutrophil extracellular trap (NET) formation is involved in atherothrombosis., Objectives: We sought to investigate whether statins affect neutrophil extracellular traps activation and release (NETosis) in coronary artery disease (CAD), and whether such changes show associations with statin‑induced additional effects., Patients and Methods: We studied 130 patients with advanced CAD before and at least 6 months after initiation of high‑dose statin therapy with rosuvastatin 40 mg/d or atorvastatin 80 mg/d. The levels of circulating citrullinated histone H3 (H3cit), myeloperoxidase (MPO), and neutrophil elastase (NE) were assessed as proteins associated with NETosis along with thrombin generation, plasma clot permeability (Ks), clot lysis time (CLT), and fibrinolysis inhibitors., Results: Following statin therapy intensification, we observed reduced accumulation of H3cit (-30.4%), MPO (-28.1%), and NE (-25.5%; all P <0.001), all not associated with low‑density lipoprotein cholesterol (LDL‑C) lowering (-25%). However, H3cit level was lower in 50 patients (38.5%) who achieved the target LDL‑C below 1.8 mmol/l (-16.5%; P = 0.004), and in 19 patients (14.6%) with LDL‑C below 1.4 mmol/l (-25.5%; P = 0.001), as compared with the remaining individuals. The reductions in H3cit and MPO levels were associated with a 42.9% decrease in C‑reactive protein (CRP) level on high‑dose statins (R = 0.855; P <0.001 and R = 0.25; P = 0.004, respectively), along with increases in Ks and reduction in thrombin activatable fibrinolysis inhibitor (TAFI) activity, but not with CLT or thrombin generation (all |R|, 0.24-0.4; P <0.01). In multivariable analysis, changes in CRP (β = 0.771; P <0.001), TAFI activity (β = 0.125; P = 0.013), and fibrinogen level (β = 0.106; P = 0.034) were independently associated with a decrease in H3cit concentration., Conclusions: We showed for the first time that high‑dose statins can reduce the level of NET‑related proteins in association with anti‑inflammatory and antithrombotic actions in CAD patients.

Background: The impact of rosuvastatin versus atorvastatin on new-onset diabetes mellitus (NODM) among patients treated with high-intensity statin therapy for coronary artery disease (CAD) remains to be clarified. This study aimed to evaluate the risk of NODM in patients with CAD treated with rosuvastatin compared to atorvastatin in the randomized LODESTAR trial., Methods: In the LODESTAR trial, patients with CAD were randomly assigned to receive either rosuvastatin or atorvastatin using a 2-by-2 factorial randomization. In this post-hoc analysis, the 3-year incidence of NODM was compared between rosuvastatin and atorvastatin treatment in the as-treated population with high-intensity statin therapy as the principal population of interest., Results: Among 2932 patients without diabetes mellitus at baseline, 2377 were included in the as-treated population analysis. In the as-treated population with high-intensity statin therapy, the incidence of NODM was not significantly different between the rosuvastatin and atorvastatin groups (11.4% [106/948] versus 8.8% [73/856], hazard ratio [HR] = 1.32, 95% confidence interval [CI] = 0.98 to 1.77, P = 0.071). When the risk of NODM with rosuvastatin versus atorvastatin was assessed according to the achieved low-density lipoprotein cholesterol (LDL-C) level, the risk of NODM began to increase at a LDL-C level below 70 mg/dL. The incidence of NODM was significantly greater in the rosuvastatin group than it was in the atorvastatin group when the achieved LDL-C level was < 70 mg/dL (13.9% versus 8.0%; HR = 1.79, 95% CI 1.18 to 2.73, P = 0.007)., Conclusions: Among CAD patients receiving high-intensity statin therapy, the incidence of NODM was not significantly different between rosuvastatin and atorvastatin. However, a drug effect of the statin type on NODM was observed when the achieved LDL-C level was < 70 mg/dL., Trial Registration: ClinicalTrials.gov, Identifier: NCT02579499., (© 2024.

Background: Statins are the first-line treatment for dyslipidemia, which is a major modifiable risk factor for atherosclerotic cardiovascular disease. Studies have shown that in addition to the beneficial lipid-lowering effect, statins also exhibit a number of pleiotropic effects that may find application in other diseases, including osteoporosis. This study aimed to assess the effect of statins on bone turnover, as measured by the concentration of bone turnover markers, and to compare the effect of atorvastatin as a lipophilic statin and rosuvastatin as a hydrophilic statin., Methods: This study included 34 postmenopausal women aged < 65 years with newly diagnosed dyslipidemia requiring statin therapy. Patients were randomly assigned to receive a statin drug. Statins were initiated at standard doses of 5 to 10 mg of rosuvastatin and 20 mg of atorvastatin. The levels of C-terminal telopeptide of type I collagen as a bone resorption marker and N-terminal propeptide of procollagen type I as a marker of bone formation, lipid concentrations and other biochemical parameters were assessed at baseline and after 6 and twelve months of treatment., Results: There were no statistically significant differences between the levels of bone turnover markers before and 6 months after statin implementation (P > .05) - for all patients or subgroups according to statin use. Analysis of the results showed that after 12 months, there was a statistically significant decrease in N-terminal propeptide of procollagen type I concentration in all subjects (P = .004). By statin subgroup, a statistically significant decrease in N-terminal propeptide of procollagen type I was observed only in patients receiving rosuvastatin (P = .012) and not in those receiving atorvastatin (P = .25). Moreover, changes in bone turnover markers did not correlate with changes in lipid concentrations., Conclusions: These results may indicate the superiority of atorvastatin over rosuvastatin in inhibiting adverse changes in bone turnover in postmenopausal women. Confirmed by studies involving a larger population, the observed differences might find particular applications in clinical practice, and the choice of atorvastatin over rosuvastatin for women could be considered in the early postmenopausal period to reduce the risk of osteoporosis and subsequent osteoporotic fractures., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2024 the Author(s).

Importance: In patients with coronary artery disease, some guidelines recommend initial statin treatment with high-intensity statins to achieve at least a 50% reduction in low-density lipoprotein cholesterol (LDL-C). An alternative approach is to begin with moderate-intensity statins and titrate to a specific LDL-C goal. These alternatives have not been compared head-to-head in a clinical trial involving patients with known coronary artery disease., Objective: To assess whether a treat-to-target strategy is noninferior to a strategy of high-intensity statins for long-term clinical outcomes in patients with coronary artery disease., Design, Setting, and Participants: A randomized, multicenter, noninferiority trial in patients with a coronary disease diagnosis treated at 12 centers in South Korea (enrollment: September 9, 2016, through November 27, 2019; final follow-up: October 26, 2022)., Interventions: Patients were randomly assigned to receive either the LDL-C target strategy, with an LDL-C level between 50 and 70 mg/dL as the target, or high-intensity statin treatment, which consisted of rosuvastatin, 20 mg, or atorvastatin, 40 mg., Main Outcomes and Measures: Primary end point was a 3-year composite of death, myocardial infarction, stroke, or coronary revascularization with a noninferiority margin of 3.0 percentage points., Results: Among 4400 patients, 4341 patients (98.7%) completed the trial (mean [SD] age, 65.1 [9.9] years; 1228 females [27.9%]). In the treat-to-target group (n = 2200), which had 6449 person-years of follow-up, moderate-intensity and high-intensity dosing were used in 43% and 54%, respectively. The mean (SD) LDL-C level for 3 years was 69.1 (17.8) mg/dL in the treat-to-target group and 68.4 (20.1) mg/dL in the high-intensity statin group (n = 2200) (P = .21, compared with the treat-to-target group). The primary end point occurred in 177 patients (8.1%) in the treat-to-target group and 190 patients (8.7%) in the high-intensity statin group (absolute difference, -0.6 percentage points [upper boundary of the 1-sided 97.5% CI, 1.1 percentage points]; P < .001 for noninferiority)., Conclusions and Relevance: Among patients with coronary artery disease, a treat-to-target LDL-C strategy of 50 to 70 mg/dL as the goal was noninferior to a high-intensity statin therapy for the 3-year composite of death, myocardial infarction, stroke, or coronary revascularization. These findings provide additional evidence supporting the suitability of a treat-to-target strategy that may allow a tailored approach with consideration for individual variability in drug response to statin therapy., Trial Registration: ClinicalTrials.gov Identifier: NCT02579499.

Background and Aims: Cardiovascular risk in heterozygous familial hypercholesterolaemia (HeFH) is driven by LDL cholesterol levels. Since lipid response to statin therapy presents individual variation, this study aimed to compare mean LDL and non-HDL cholesterol reductions and their variability achieved with different types and doses of the most frequently prescribed statins., Methods and Results: Among primary hypercholesterolaemia cases on the Spanish Arteriosclerosis Society registry, 2894 with probable/definite HeFH and complete information on drug therapy and lipid profile were included. LDL cholesterol reduction ranged from 30.2 ± 17.0% with simvastatin 10 mg to 48.2 ± 14.7% with rosuvastatin 40 mg. After the addition of ezetimibe, an additional 26, 24, 21 and 24% reduction in LDL cholesterol levels was obtained for rosuvastatin, 5, 10, 20 and 40 mg, respectively. Subjects with definite HeFH and a confirmed genetic mutation had a more discrete LDL cholesterol reduction compared to definite HeFH subjects with no genetic mutation. A suboptimal response (<15% or <30% reduction in LDL cholesterol levels, respectively with low-/moderate-intensity and high-intensity statin therapy) was observed in 13.5% and, respectively, 20.3% of the subjects., Conclusion: According to the LDL cholesterol reduction in HeFH patients, the ranking for more to less potent statins was rosuvastatin, atorvastatin and simvastatin; however, at maximum dosage, atorvastatin and rosuvastatin were nearly equivalent. HeFH subjects with positive genetic diagnosis had a lower lipid-lowering response. Approximately 1 in 5 patients on high-intensity statin therapy presented a suboptimal response., Competing Interests: Declaration of competing interest Dr. Climent has nothing to disclose.

Background: Statins are potential drugs for decreasing risk of atherosclerotic cardiovascular complications in type 2 diabetic (T2D) patients., Purpose: To examine the efficacy of both rosuvastatin (ROSUVA) and atorvastatin (ATORVA) on LV function and markers of inflammation in T2D patients with dyslipidemia., Methods: One hundred-sixty T2D patients were assigned to receive either atorvastatin (ATORVA group, n = 80, 40 mg) or rosuvastatin (ROSUVA group, n = 80, 10 mg), daily for 6 months. Blood was collected for biochemical analysis. The prevalence of left ventricular abnormalities was determined by echocardiography and two-dimensional Speckle-Strain to assess Global Longitudinal Strain (GLS)., Results: ROSUVA vs. ATORVA resulted in significant (p < 0.001) reduction in HbA1c % (9.13 vs 2.35%), LDL-C (22.23% vs. 14.75%), triglycerides (13.56 % vs. 8.21 %), total cholesterol (16.10 % vs. 10.81 %), atherogenic index (18.08. % vs. 10.97%), hs-CRP (23.51 % vs.18.96%), sortilin (33.33 % % vs. 15.08 %), and leptin (31.81 % vs. 23.17 %) but increased adiponectin (97.99 % vs.76.47.1 %) and HDL-C (76.47 % vs. 0.21 %) compared with baseline, respectively. Negative correlations between adiponectin and each of hs-CRP, HbA1c%, total cholesterol, LDL-C, atherogenic index and leptin were found. Also, left ventricular functions were correlated with adiponectin, lipids, HbA1c% and hs-CRP. The areas under receiver operating characteristic curve (AUC) showed that hs-CRP, leptin, sortlin, leptin, and adiponectin were good predictors for cardiovascular events., Conclusion: ROSUVA is more efficacious in improving lipid profile, atherogenic index and modulation of inflammatory biomarkers in dyslipidemic T2D patients compared with ATROVA. However, both statins are equivalent as cardioprotective agents in dyslipidemic T2D patients., (Copyright © 2020. Published by Elsevier Masson SAS.)

Background: High-intensity statin therapy is typically used in patients with acute myocardial infarction (AMI) for secondary prevention. However, there have been consistent concerns regarding its association with diabetes mellitus. We investigated the effect of high-intensity atorvastatin and rosuvastatin on new-onset diabetes mellitus (NODM) and cardiovascular outcomes over a 3-year follow-up period., Methods: Data from the Korea Acute Myocardial Infarction Registry were collected from November 2011 to October 2015, and 13,104 patients with AMI were enrolled from major cardiovascular centers. Among them, 2221 patients without diabetes who had been administered with high-intensity atorvastatin (40-80 mg) and rosuvastatin (20 mg) were investigated. The atorvastatin and rosuvastatin groups were evaluated for the incidence of NODM and major adverse cardiac events (MACE) including death, myocardial infarction, and revascularization cases in the following 3 years., Results: Baseline characteristics were comparable between the two groups. Event-free survival rate of NODM was not significantly different between the atorvastatin and rosuvastatin groups (92.5% vs. 90.8%, respectively; Log-rank P-value = 0.550). The event-free survival rate of MACE was also not significantly different between atorvastatin and rosuvastatin groups (89.0% vs. 89.6%, respectively; Log rank P-value = 0.662). Multivariate Cox analysis revealed that statin type was not a prognostic factor in the development of NODM and MACE., Conclusions: Administering high-intensity atorvastatin and rosuvastatin in patients with AMI produced comparable effects on NODM and clinical outcomes, suggesting their clinical equivalence in secondary prevention.

Statins have been shown to reduce the risk of post-contrast acute kidney injury (PC-AKI) in patients undergoing percutaneous coronary intervention (PCI). However, the preventive effect of rosuvastatin versus atorvastatin on PC-AKI in patients with ST-segment elevation myocardial infarction (STEMI) undergoing PCI remains unclear. Patients with STEMI undergoing PCI between January 2010 and May 2016 were consecutively enrolled. A total of 1300 included patients were divided into two groups according to the statin type (atorvastatin: n = 1040; rosuvastatin: n = 260). The primary endpoint was PC-AKI defined as an absolute increase of ≥ 0.5 mg/dL in the level of serum creatinine or an increase of ≥ 25 % over baseline within 48-72 h after contrast media exposure. In total, 245 (18.8 %) patients developed PC-AKI. The atorvastatin and rosuvastatin groups had similar rates of PC-AKI (19.1 % vs. 17.7 %, p = 0.595), in-hospital mortality (4.1 % vs. 3.8 %, p = 0.833), and major adverse clinical events (MACE). Multivariate logistic regression analysis revealed that rosuvastatin treatment had an effect similar to atorvastatin regarding PC-AKI (odds ratio [OR] = 0.97, 95 % confidence interval [CI], 0.66-1.43, p = 0.874). Propensity score analyses and subgroup analysis demonstrated similar results for PC-AKI. Kaplan-Meier survival curves and Cox proportional regression showed that the atorvastatin and rosuvastatin groups had no differences regarding follow-up mortality. Rosuvastatin exerted a similar preventive effect against PC-AKI and showed similar levels of in-hospital and follow-up all-cause mortality and in-hospital MACE compared with atorvastatin in patients with STEMI undergoing PCI., Competing Interests: Declaration of Competing Interest The authors declare that there is no conflict of interest., (Copyright © 2020 The Authors.

Objective: To conduct a randomized double-blind prospective study to investigate effect of different doses of atorvastatin, rosuvastatin, and simvastatin on elderly patients with ST-elevation AMI after PCI., Methods: One hundred and ninety-two AMI patients over 60 years old who underwent PCI were randomly divided into six groups: the low atorvastatin group, high atorvastatin group; low rosuvastatin group; high rosuvastatin group; low simvastatin group; high simvastatin group. Demographic data and clinical information as well as coronary angiography parameters were recorded. Plasma levels of CK-MB, BNP, ALT, and TnI were measured at 12 hr, 24 hr, and 1 week after PCI. Major cardiovascular events (MACE) were recorded and analyzed using Kaplan-Meier (K-M) curve., Results: No significant differences were observed in angiographic and procedural characteristics. In all high dose groups, all levels of CK-MB, BNP, ALT, and TnI were significantly lower. However, after 1 week of PCI, only CK-MB, BNP, and TnI showed significant difference between high and low dose groups. Patients in high dose groups had significantly lower rates for surgical or percutaneous intervention, recurrence of angina, and rehospitalization. K-M curve analysis also showed cumulative incidence freedom time of overall MACE in high dose groups was significantly longer. No significant differences were found among different drugs with the same doses., Conclusion: Patients with higher doses had lower level of CK-MB, BNP, ALT, and TnI and lower occurrence of MACE after PCI., (© 2020 Wiley Periodicals, Inc.)

Introduction: Atorvastatin-80mg/day and Rosuvastatin-40mg/day are the commonest high-dose statin (3-hydroxy-3-methylglutaryl coenzyme-A reductase inhibitors) regimes for post-PCI (Percutaneous Coronary Interventions) patients to lower (by ≥50%) blood low-density-lipoprotein cholesterol (LDL-C). Dearth of conclusive evidence from developing world, regarding overall safety, tolerability and comparative effectiveness (outcome/safety/tolerability/endothelial inflammation control) of Rosuvastatin over Atorvastatin in high-dose, given its higher cost, called for an overall and comparative assessment among post-PCI patients in a tertiary cardiac-care hospital of Kolkata, India., Methods: A record-based non-concurrent cohort study was conducted involving 942 post-PCI patients, aged 18-75 years, on high-dose statin for three months and followed up for ≥one year. Those on Atorvastatin-80mg (n = 321) and Rosuvastatin-40mg (n = 621) were compared regarding outcome (death/non-fatal myocardial infarction: MI/repeated hospitalization/target-vessel revascularisation/control of LDL and high-sensitivity C-reactive protein: hsCRP), safety (transaminitis/myopathy/myalgia/myositis/rhabdomyolysis), tolerability (gastroesophageal reflux disease: GERD/gastritis) and inflammation control adjusting for socio-demographics, tobacco-use, medications and comorbidities using SAS-9.4., Results: Groups varied minimally regarding distribution of age/gender/tobacco-use/medication/comorbidity/baseline (pre-PCI) LDL and hs-CRP level. During one-year post-PCI follow up, none died. One acute MI and two target vessel revascularizations occurred per group. Repeated hospitalization for angina/stroke was 2.18% in Atorvastatin group vs. 2.90% in Rosuvastatin group. At three-months follow up, GERD/Gastritis (2.18% vs 4.83%), uncontrolled hs-CRP (22.74% vs 31.08%) and overall non-tolerability (4.67% vs. 8.21%) were lower for Atorvastatin group. Multiple logistic regression did show that compared to Atorvastatin-80mg, Rosuvastatin-40mg regime had poorer control of hs-CRP (A3OR = 1.45,p = 0.0202), higher (A3OR = 2.07) adverse effects, poorer safety profile (A3OR = 1.23), higher GERD/Gastritis (A3OR = 1.50) and poorer overall tolerability (A3OR = 1.50)., Conclusion: Post-PCI high dose statins were effective, safe and well-tolerated. High dose Rosuvastatin as compared to high dose Atorvastatin were similar in their clinical efficacy. Patients treated with Atrovastatin had significantly lower number of patients with hs-CRP (high-sensitivity C-reactive protein)/C-reactive protein (CRP) level beyond comparable safe limit and relatively better tolerated as opposed to Rosuvastatin-40mg.Thus given the lower price, Atorvastatin 80mg/day appeared to be more cost-effective. A head-to-head cost-effectiveness as well as efficacy trial may be the need of the hour., Competing Interests: The authors have declared that no competing interests exist.

Background: High-intensity statin therapy is recommended in patients with clinical atherosclerotic cardiovascular disease (ASCVD) or at high risk of ASCVD. Current evidence demonstrates efficacy of high-intensity statin therapy in reducing major adverse cardiovascular events; yet the comparative safety profile between high-intensity statin agents remains unknown. In 2011, when atorvastatin became generic, the Veteran's Health Administration made the formulary switch from rosuvastatin to atorvastatin. Currently, rosuvastatin is generic; however, at the time of this study, it was still under patent. Objective: The primary objective was to determine if high-intensity atorvastatin compared with rosuvastatin is associated with an increased incidence of adverse drug reactions (ADRs) in the veteran population. Methods: A retrospective cohort study at James A. Haley Veterans' Hospital compared patients receiving rosuvastatin 20 to 40mg from January 2009 to November 2011 (n = 4,165) and atorvastatin 40 to 80mg from May 2012 to June 2016 (n = 5,852). Patients were excluded if they were nonadherent to statin therapy or had a documented ADR to atorvastatin prior to formulary switch. Results: A difference in overall ADR rates was found between atorvastatin and rosuvastatin groups (4.59% vs 2.91%; odds ratio [OR], 1.61; 95% CI, 1.29 to 2.00; P < 0.05). Statistically significant differences in abnormal liver transaminases (3.99% vs 1.39%; OR, 2.95; 95% CI, 2.21 to 3.94; P < 0.05) and statin-associated muscle symptoms (1.14% vs 0.5%; OR, 2.29; 95% CI, 1.39 to 3.74; P < 0.05) were identified between groups. Patients receiving rosuvastatin were on therapy 2.5 times longer before developing an ADR. Conclusion and Relevance: High-intensity atorvastatin compared with rosuvastatin is associated with an increased incidence of ADRs.

Purpose: Impaired antiplatelet effect of clopidogrel (CLP) can result from drug-drug interactions and genetic polymorphisms of drug-metabolizing enzymes. The aim of the study was to evaluate the effect of genetic polymorphisms of ABCB1 and the selected cytochrome P450 isoenzymes on the pharmacodynamics and pharmacokinetics of CLP and its metabolites in patients co-treated with atorvastatin or rosuvastatin., Methods: The study involved 50 patients after coronary angiography/angioplasty treated with CLP and atorvastatin (n = 25) or rosuvastatin (n = 25) for at least 6 months. Plasma concentrations of CLP, diastereoisomers of thiol metabolite (inactive H3 and active H4), and inactive CLP carboxylic acid metabolite were measured by UPLC-MS/MS method. Identification of the CYP2C19*2, CYP2C19*17, CYP3A4*1G, CYP1A2*1F, and ABCB1 C3435T genetic polymorphisms was performed by PCR-RFLP, while platelet reactivity units (PRU) were tested using the VerifyNow P2Y12 assay., Results: There were significant differences in the pharmacokinetic parameters of the H4 active metabolite of CLP in the atorvastatin and rosuvastatin group divided according to their CYP2C19 genotype. There were no significant associations between CYP3A4, CYP1A2, and ABCB1 genotypes and pharmacokinetic parameters in either statin groups. In the multivariate analysis, CYP2C19*2 genotype and non-genetic factors including BMI, age, and diabetes significantly affected platelet reactivity in the studied groups of patients (P < 0.01). In the atorvastatin group, CYP2C19*2, CYP3A4*1G, and ABCB1 C3435T TT genotypes were independent determinants of PRU values (P < 0.01)., Conclusion: The CYP2C19*2 allele is the primary determinant of the exposition to the H4 active metabolite of clopidogrel and platelet reactivity in patients co-treated with atorvastatin or rosuvastatin.

Objective: The aim is to compare atorvastatin versus rosuvastatin on secondary percutaneous coronary intervention (PCI) rate and explore risk factors in coronary heart disease (CHD) patients., Methods: A cohort study with 283 CHD subjects was launched from 2011 to 2015. Cox proportional hazards regression model, Receiver Operating Characteristic (ROC) and nomogram were used to compare the effect of atorvastatin and rosuvastatin on secondary PCI rate and disease risk factors. Even why the two statins had different effects based on gene expression profile analysis has been explored., Results: Gene FFA (Freely fatty acid), AST (Aspartate Transaminase) and ALT (Alanine transaminase) showed the statistical difference between the four statin groups (P<0.05). In the AA group (Continuous Atorvastatin usage), albumin was a risk factor (Hazard Ratio (HR):1.076, 95%CI (1.001, 1.162), p<0.05). In the AR group (Start with Atorvastatin usage, then change to Rosuvastatin usage), ApoA was a protective factor (HR:0.004, 95%CI (0.001, 0.665), p<0.05). GLB (Galactosidase Beta) was a risk factor (HR:1.262, 95%CI (1.010, 1.576), p<0.05). In RR group (Continuous Rosuvastatin usage), ApoE was a protective factor (HR:0.943, 95%CI (0.890, 1.000), <0.05). ALT was a risk factor (HR:1.030, 95%CI (1.000, 1.060), p<0.05)., Conclusion: Patients in the RA group had the lowest secondary PCI rate. ALT was a risk factor in the RR group. Gene Gpt (Glutamic Pyruvic Transaminase) encoded for one subtype of ALT had a significantly different expression in different statin groups., (Copyright© Bentham Science Publishers; For any queries, please email at epub@benthamscience.net.)

Background: There is no randomized clinical trials with recurrence of atherosclerotic cardiovascular disease (ASCVD) as a major outcome with rosuvastatin. In order to analyze potential differences in the clinical response to atorvastatin and rosuvastatin in secondary ASCVD prevention, we have analyzed the clinical evolution of those subjects of the Dyslipemia Registry of the Spanish Society of Arteriosclerosis (SEA) who at the time of inclusion in the Registry had already suffered an ASCVD., Methods: This observational, retrospective, multicenter, national study was designed to determine potential differences between the use of atorvastatin and rosuvastatin in the ASCVD recurrence. Three different follow-up start-times were performed: time of inclusion in the registry; time of first event if this occurred after 2005, and time of first event without date restriction., Results: Baseline characteristics were similar between treatment groups. Among atorvastatin or rosuvastatin users, 89 recurrences of ASCVD were recorded (21.9%), of which 85.4% were coronary. At the inclusion of the subject in the registry, 345 participants had not suffered a recurrence yet. These 345 subjects accumulated 1050 person-years in a mean follow-up of 3 years. Event rates were 2.73 (95% CI: 1.63, 4.25) cases/100 person-years and 2.34 (95% CI: 1.17, 4.10) cases/100 person-years in the atorvastatin and rosuvastatin groups, respectively. There were no statistically significant differences between the two groups independently of the follow-up start-time., Conclusions: This study does not find differences between high doses of rosuvastatin and atorvastatin in the recurrence of ASCVD, and supports their use as clinically equivalent in secondary prevention of ASCVD.

Aim: The PLANET trials showed that atorvastatin 80 mg but not rosuvastatin at either 10 or 40 mg reduced urinary protein to creatinine ratio (UPCR) at similar effects on LDL-cholesterol. However, individual changes in both UPCR and LDL-cholesterol during treatment with these statins varied widely between patients. This inter-individual variability could not be explained by patients' physical or biochemical characteristics. We assessed whether the plasma concentrations of both statins were associated with LDL-cholesterol and UPCR response., Materials and Methods: The PLANET trials randomized patients with a UPCR of 500-5000 mg/g and fasting LDL-cholesterol >2.33 mmol/L to a 52-week treatment with atorvastatin 80 mg, rosuvastatin 10 mg or 40 mg. For the current analysis, patients with available samples at week 52 and treatment compliance >80% by pill count were included (N = 295). The main outcome measurements were percentage change in UPCR and absolute change in LDL-cholesterol (delta LDL) from baseline to week 52., Results: Median (interquartile range) plasma concentration at week 52 for atorvastatin 80 mg was 3.9 ng/mL (IQR: 2.1 to 8.7), for rosuvastatin 10 mg 1.0 ng/mL (IQR: 0.7 to 2.0) and for rosuvastatin 40 mg 3.5 ng/mL (IQR: 2.0 to 6.8). Higher plasma concentration of statin was associated with larger LDL-cholesterol reductions at week 52 [rosuvastatin r = -0.40 (P < .001); atorvastatin r = -0.28 (P = .006)]. The plasma concentration of both statins did not correlate with UPCR change [rosuvastatin r = 0.07 (P = .30); atorvastatin r = 0.16 (P = .13)]., Conclusions: Individual variation in plasma concentrations of rosuvastatin and atorvastatin was associated with LDL-cholesterol changes in patients. The individual variation in UPCR change was not associated with the plasma concentration of both statins., (© 2019 The Authors. Diabetes, Obesity and Metabolism published by John Wiley & Sons Ltd.)

Importance: High-intensity statin use after myocardial infarction (MI) varies by patient characteristics, but little is known about differences in use by hospital or region., Objective: To explore the relative strength of associations of region and hospital and patient characteristics with high-intensity statin use after MI., Design, Setting, and Participants: This retrospective cohort analysis used Medicare administrative claims and enrollment data to evaluate fee-for-service Medicare beneficiaries 66 years or older who were hospitalized for MI from January 1, 2011, through June 30, 2015, with a statin prescription claim within 30 days of discharge. Data were analyzed from January 4, 2017, through May 12, 2019., Exposures: Beneficiary characteristics were abstracted from Medicare data. Hospital characteristics were obtained from the 2014 American Hospital Association Survey and Hospital Compare quality metrics. Nine regions were defined according to the US Census., Main Outcomes and Measures: Intensity of the first statin claim after discharge characterized as high (atorvastatin calcium, 40-80 mg, or rosuvastatin calcium, 20-40 mg/d) vs low to moderate (all other statin types and doses). Trends in high-intensity statins were examined from 2011 through 2015. Associations of region and beneficiary and hospital characteristics with high-intensity statin use from January 1, 2014, to June 15, 2015, were examined using Poisson distribution mixed models., Results: Among the 139 643 fee-for-service beneficiaries included (69 968 men [50.1%] and 69 675 women [49.9%]; mean [SD] age, 76.7 [7.5] years), high-intensity statin use overall increased from 23.4% in 2011 to 55.6% in 2015, but treatment gaps persisted across regions. In models considering region and beneficiary and hospital characteristics, region was the strongest correlate of high-intensity statin use, with 66% higher use in New England than in the West South Central region (risk ratio [RR], 1.66; 95% CI, 1.47-1.87). Hospital size of at least 500 beds (RR, 1.15; 95% CI, 1.07-1.23), medical school affiliation (RR, 1.11; 95% CI, 1.05-1.17), male sex (RR, 1.10; 95% CI, 1.07-1.13), and patient receipt of a stent (RR, 1.35; 95% CI, 1.31-1.39) were associated with greater high-intensity statin use. For-profit hospital ownership, patient age older than 75 years, prior coronary disease, and other comorbidities were associated with lower use., Conclusions and Relevance: This study's findings suggest that geographic region is the strongest correlate of high-intensity statin use after MI, leading to large treatment disparities.

Statins are widely used to lower cholesterol and to reduce cardiovascular events. Whether all statins have similar effects on plaque stabilization is unknown. We aimed to investigate coronary plaque response to treatment with different statins that result in similar lipid reduction using serial multimodality intracoronary imaging. Patients with de novo coronary artery disease requiring intervention were randomized to rosuvastatin 10mg (R10) or atorvastatin 20mg (A20) daily. Optical coherence tomography and intravascular ultrasound were performed at baseline, 6 months, and 12 months. Untreated nonculprit plaques were analyzed by optical coherence tomography for thin-cap fibroatheroma, minimum fibrous cap thickness, lipid arc, and lipid length. Total and percent atheroma volume, respectively were analyzed by intravascular ultrasound. Forty-three patients completed the protocol (R10: 24 patients, 31 plaques; A20: 19 patients, 30 plaques). The decrease in serum lipids was similar. From baseline to 6 months to 12 months, minimum fibrous cap thickness increased in the R10 group (61.4 ± 15.9 µm to 120.9 ± 57.9 µm to 171.5 ± 67.8 µm, p <0.001) and the A20 group (60.8 ± 18.1 µm to 99.2 ± 47.7 µm to 127.0± 66.8 µm, p <0.001). Prevalence of thin-cap fibroatheroma significantly decreased in the R10 and A20 groups (-48% and -53%, respectively, p <0.001 for intragroup comparisons). Only the R10 group had a decrease in macrophage density (-23%, p = 0.04) and microvessels (-12%, p = 0.002). Total atheroma volume decreased in the R10 group (109.2 ± 62.1 mm 3 to 101.8 ± 61.1 mm 3 to 102.5 ± 62.2 mm 3 , p = 0.047) but not in the A20 group (83.3 ± 48.5mm 3 to 77.6 ± 43.0 mm 3 to 77.9 ± 48.6 mm 3 , p = 0.07). In conclusion, although both statins demonstrated similar reductions in lipid profiles, the rosuvastatin group showed more rapid and robust plaque stabilization, and regression of plaque volume compared to the atorvastatin group., (Copyright © 2019 Elsevier Inc.

Although statin use in patients with acute myocardial infarction (AMI) is mandatory, it has been suggested to be associated with new-onset diabetes mellitus (NODM). In real world practice, moderate-intensity statin therapy is more commonly used than high-intensity statin therapy. In this study, we investigated the impact of moderate-intensity pitavastatin (2 to 4 mg) compared with moderate-intensity atorvastatin (10 to 20 mg) and rosuvastatin (5 to 10 mg) on the development of NODM during a follow-up period of up to 3years. Between November 2011 and May 2015, 2001 patients with AMI who did not have diabetes mellitus were investigated. The cumulative incidence of NODM was evaluated in all groups. To adjust for potential confounders, multinomial propensity scores were used. Cox proportional hazard models were used to assess the hazard ratio of NODM in the atorvastatin and rosuvastatin groups compared with pitavastatin group. The cumulative incidence of NODM was significantly lower in pitavastatin group compared with the atorvastatin and rosuvastatin groups (3.0% vs 8.4% vs 10.4%, respectively; Log-rank p value = 0.001). After weighting the baseline characteristics of the 3 statin groups by multinomial propensity scores, atorvastatin (hazard ratio: 2.615, 95% confidence interval: 1.163 to 5.879) and rosuvastatin (hazard ratio: 3.906, 95% confidence interval: 1.756 to 8.688) were found to be associated with a higher incidence of NODM compared with pitavastatin therapy on multivariable analysis. Moderate-intensity pitavastatin therapy is associated with a lower incidence of NODM in patients with AMI andhas similar clinical outcomes to moderate-intensity atorvastatin and rosuvastatin therapy., (Copyright © 2018 Elsevier Inc.

Previous studies have shown that the commonly used statin lipid lowering drugs can delay the progression of atherosclerotic plaque. Atorvastatin can stabilize atherosclerotic plaque, but it can not reverse atheromatous plaque. This study will compare the efficacy of rosuvastatin and atorvastatin in the treatment of atherosclerosis and try to prove that the use of statins can improve peripheral atherosclerosis and reverse atherosclerotic plaque. The results showed that 10 mg rosuvastatin was more effective than 20 mg atorvastatin in lowering serum lipid level and elevating ABI index, ABI as rosuvastatin group (0.782±0.236) and atorvastatin group(0.541±0.196). After 6 months of treatment, the carotid artery IMT in rosuvastatin group and atorvastatin group decreased compared with before treatment, and the difference was statistically significant (P<0.05). The TC/mmol⋅L-1 is 2.83±0.56 in rosuvastatin group and 3.24±0.71 in atorvastatin group. In addition, rosuvastatin did not increase the risk of adverse reactions compared with atorvastatin. The results confirm that statin therapy can improve peripheral atherosclerosis and reverse atherosclerotic plaques.

Augmented sympathetic nerve activity is associated with heart failure with preserved left ventricular ejection fraction (HFpEF). Lipophilic statins reduce sympathetic nerve activity in patients with heart failure with reduced left ventricular ejection fraction. However, little is known about whether all types of statins, regardless of solubility, reduce sympathetic nerve activity in HFpEF. We evaluated the effect of atorvastatin, a lipophilic statin, and rosuvastatin, a hydrophilic statin, on muscle sympathetic nerve activity (MSNA) in HFpEF patients. This study was conducted as a prospective, randomized, open-label, crossover trial. Ten HFpEF patients with untreated hyperlipidemia participated in this study. Subjects were assigned to either the atorvastatin (lipophilic) or the rosuvastatin (hydrophilic) group with each drug administered for 8 weeks. Atorvastatin and rosuvastatin treatment resulted in a similar reduction in low-density lipoprotein cholesterol (LDL-C) levels. There was no difference in the effect of either treatment on blood pressure, heart rate, or left ventricular function. Atorvastatin significantly decreased MSNA frequency compared with baseline (31.5 ± 6.3 vs. 47.5 ± 10.7 bursts/min, p < 0.01), but rosuvastatin had no effect on MSNA (40.9 ± 7.3 bursts/min). MSNA was significantly lower in the atorvastatin group than rosuvastatin group (p < 0.05). However, the reduction in MSNA seen in either group did not correlate with the reduction in LDL-C. No significant differences were observed in either the baroreflex control of heart rate or MSNA between the two groups. These results suggest that lipophilic statins have a favorable effect on sympathetic nerve activity beyond lowering LDL-C in HFpEF, but hydrophilic statins do not., (Copyright © 2018 Elsevier B.V.

Serum troponin within the normal range is an emerging predictor of cardiovascular mortality. We aimed to determine how rapidly high-sensitivity troponin-I (hs-cTnI) levels are lowered by statin therapy in patients with stable cardiovascular disease. In the RADAR substudy, patients were randomized to atorvastatin 20 mg/day (n = 39) or rosuvastatin 10 mg/day (n = 39) and up-titrated at 6-week intervals to 80 mg of atorvastatin or 40 mg of rosuvastatin. Hs-cTnI concentrations were measured at baseline and at 6 and 18 weeks of follow-up. Statin treatment resulted in a mean change of serum hs-cTnI of -8.2% (P = 0.010) after 6 weeks and -12.3% (P = 0.001) after 18 weeks. After 18 weeks, hs-cTnI levels were lowered by 21.8% with atorvastatin and by 4.1% with rosuvastatin (P = 0.001 and P = 0.133, respectively). During statin therapy, serum hs-cTnI levels decreased rapidly within weeks of treatment, suggesting an effect beyond long-term atherosclerosis regression. Mechanisms that mediate this effect require further study., (© 2018 American Society for Clinical Pharmacology and Therapeutics.)

Introduction: Statins can reduce cardiovascular events and improve endothelial function. However, differences in the effect of statins on endothelial dysfunction have not been researched sufficiently. Here, we aimed to compare the effects of atorvastatin versus rosuvastatin on endothelial function via flow-mediated and endothelial-independent dilation., Methods: Hyperlipidaemic subjects on treatment with statins for one year (either 20 mg/day atorvastatin or 10 mg/day rosuvastatin) were enrolled in the study. In accordance with the literature, flow-mediated dilation (FMD) and nitrate-mediated endothelium-independent dilation (EID) were measured by ultrasonography on the right brachial artery of each subject. Baseline and final measurements were compared in each group and between the groups., Results: One hundred and four subjects (50 atorvastatin and 54 rosuvastatin users) were enrolled in the study. Fifty-eight subjects were female. The groups were statistically similar in terms of age and body mass index, and haemoglobin, creatinine, total cholesterol, triglyceride, high-density lipoprotein and low-density lipoprotein cholesterol levels. In each group, the mean final FMD and EID values were higher compared to their respective baseline values, but the mean changes in FMD and EID were statistically similar in both groups (p = 0.958 for FMD and 0.827 for EID). There was no statistically significant difference between the atorvastatin and rosuvastatin groups in terms of final FMD and EID values (p = 0.122 and 0.115, respectively)., Conclusions: This study demonstrated that both one-year atorvastatin and rosuvastatin treatments significantly improved endothelial function, when assessed with FMD and EID and measured by ultrasonography. However, the amount of improvement in endothelial dysfunction was similar in the two treatments.

Atherosclerosis (AS) is a chronic inflammatory reaction with the pathological changes in the lipid deposition of arterial intima. The disorder of blood lipid metabolism is the main factor of the occurrence and development of AS, and the inflammatory reaction and autoimmune reaction also run through the development of AS. In this study, we compared the efficacy and safety of atorvastatin, simvastatin, pravastatin and rosuvastatin in the treatment of AS. At the same time, we used high resolution magnetic resonance imaging (MRI) to assess the changes in plaque area in the middle cerebral artery and the patch area before and after drug treatment. After 6 months of treatment, the number of intima-media thickness (IMT), plaque and plaque in each group were significantly lower than that before the same group. The results showed that statin treatment of AS could significantly reduce the level of blood lipids, but rosuvastatin and atorvastatin had better effects on anti inflammation and maintaining plaque stability and the drug safety was good.

Background: Abnormalities in the physical properties of the red blood cells (RBCs) membranes may underlie the defects that are strongly linked to cardiovascular diseases (CVD). The aim of the study was to compare the effects of two therapies of equal hipolipemic efficacy on the erythrocyte membrane fluidity, concentration of membrane cholesterol, lipids peroxidation and RBCs distribution witdh in patients with CVD., Methods: The study included 44 patients with angiographic evidence of CVD, who despite previous 6-month hypolipemic therapy, did not achieve the concentration of LDL-C <70mg/dl. They were randomly assigned to: rosuvastatin 20mg/day (R20) and atorvastatin 10mg/day combined with ezetimibe 10mg/day (A10+E10). The membrane fluidity, the concentration of thiobarbituric acid reactive substances -TBARS, concentration of membrane cholesterol were evaluated after 6 months therapy., Results: An improvement in lipid parameters was observed in each of the groups studied. In R20 the treatment resulted in 33% reduction concentrations of TBARS in serum, as well as in a decrease in membrane cholesterol by 16%, fluorescence anisotropy of TMA-DPH by 17.7%, fluorescence anisotropy of DPH by 2.8%. In A10+E10 the reduction of TBARS by 20.5% in serum, membrane cholesterol by 15.8% as well as a 14.25% increase in RBC membrane fluidity in the superficial layer (TMA-DPH) and decrease fluidity in the deep layer (DPH) were observed., Conclusion: Rosuvastatin increases the fluidity of erythrocyte membrane and decreases the TBARS in serum to greater extent than does equal hipolipemic combined therapy atorvastatin with ezetimibe., (Copyright © 2017 Institute of Pharmacology, Polish Academy of Sciences.

Objective: We used individual patient data from the VOYAGER database to estimate cardiovascular (CV) risk reduction with commonly used high-intensity statins., Methods: In patients with known atherosclerotic CV disease (ASCVD) treated with high-intensity statin therapy (n = 6,735), the predicted risk reduction was estimated using the Cholesterol Treatment Trialists' Collaboration meta-analysis, which determined risk reduction per 38.7 mg/dL statin-mediated reduction in low-density lipoprotein cholesterol., Results: The greatest reductions in risk were seen in major vascular events (estimated rate ratios ranged from 0.55 with rosuvastatin [RSV] 40 mg to 0.60 with atorvastatin [ATV] 40 mg) and coronary heart disease death (estimated rate ratios ranged from 0.58 with RSV 40 mg to 0.64 with ATV 40 mg)., Conclusions: Our results show that, in individuals without clinical ASCVD, statin therapy has the potential to reduce the frequency of CV events., (© 2018 S.

Background/aims: Early and intensive atorvastatin treatment can decrease nonsustained ventricular tachycardia (nsVT) in patients with ST-segment elevation myocardial infarction (STEMI). The objective of this study was to compare the effects of hydrophilic rosuvastatin and lipophilic atorvastatin on nsVT in STEMI patients treated with primary percutaneous coronary intervention (PCI)., Methods: The data from a cohort of patients undergoing primary PCI at Jinhua Municipal Central Hospital from January 1, 2013 through June 30, 2016 were analyzed. The patients were divided into the rosuvastatin group and the atorvastatin group based on which kind of statins that they had received. The endpoint of the study was the occurrence of nsVT on either electrocardiogram monitoring or Holter monitoring., Results: A total of 301 patients were enrolled in the study (rosuvastatin group: n = 103; atorvastatin group: n = 198). The baseline and procedural characteristics were similar between the two groups, except that total ischemic time in the rosuvastatin group was markedly longer than that in the atorvastatin group (8 (5-16) h vs. 6 (4-12) h; P = 0.001). The administration of rosuvastatin was significantly associated with lower occurrence of nsVT than that of atorvastatin (9.71 vs. 19.70%; P = 0.026). Multivariable logistic regression analysis suggested that the independent predictors of nsVT included rosuvastatin (odds ratio (OR) 0.397, 95% confidence interval (CI) 0.176-0.894), current smoking (OR 2.307, 95% CI 1.011-5.262), and left ventricular ejection fraction (LVEF) (OR 1.060, 95% CI 1.023-1.098)., Conclusions: The effects of rosuvastatin on nsVT might be better than that of atorvastatin in STEMI patients undergoing primary PCI.

Objective: The objective of this study was to assess the antiproliferative pleiotropic effects of statins on thyroid function, volume, and nodularity., Subjects and Methods: One hundred and six hyperlipidemic patients were included in this prospective study. The 69 patients in the statin groups received atorvastatin (16 received 10 mg and 18 received 20 mg) or rosuvastatin (20 received 10 mg and 15 received 20 mg). The 37 patients in the control group, assessed as not requiring drugs, made only lifestyle changes. Upon admission and after 6 months, all patients were evaluated by ultrasonography as well as for lipid variables (total cholesterol, high- and low-density lipoprotein cholesterol, and triglycerides) and thyroid function and structure., Results: After 6 months, no differences in thyroid function, thyroid volume, the number of thyroid nodules, or nodule size were observed in the statin and control groups. In a subgroup analysis, total thyroid volume had decreased more in patients receiving 20 mg of rosuvastatin than that in the control group (p < 0.05). Maximum nodule size had decreased more in those receiving 10 mg of rosuvastatin (p < 0.05)., Conclusions: Our results suggest an association between rosuvastatin treatment and smaller thyroid volume and maximum nodule diameter; this could be attributable to the antiproliferative effects of statin therapy on the thyroid., (© 2018 The Author(s) Published by S. Karger AG, Basel.)

Background: Diabetic nephropathy is a severe complication of Type 2 diabetes. Tubular lesions may play an important role in its early stages. The aim of our study was to determine if atorvastatin protects the podocytes and the proximal tubule in patients with Type 2 diabetes., Methods: A total of 63 patients with Type 2 diabetes completed this 6-months prospective pilot study. They were randomized to continue rosuvastatin therapy (control group) or to be administered an equipotent dose of atorvastatin (intervention group), and were assessed regarding urinary podocytes, podocyte-associated molecules, and biomarkers of proximal tubule dysfunction., Results: The patients from the intervention group presented a significant reduction in podocyturia (from 7.0 to 4.0 cells/ml, p < .05), urinary nephrin (from 1.7 to 1.3 mg/g, p < .001), urinary vascular endothelial growth factor (from 262.8 to 256.9, p < .01), urinary alpha 1 -microglobulin (from 10.0 to 8.3 mg/g, p < .01), urinary kidney injury molecule-1 (from 139.5 to 136.3 ng/g, p < .001), and urinary advanced glycation end-products (from 112.6 to 101.3 pg/ml, p < .001). Podocyturia correlated directly with the podocyte damage biomarkers, proximal tubule dysfunction biomarkers, albumin to creatinine ratio, and advanced glycation end-products, and inversely with the glomerular filtration rate., Conclusions: In patients with Type 2 diabetes, atorvastatin exerts favorable effects on the kidney. There is a correlation between the evolution of the podocytes and of the proximal tubule biomarkers, supporting the hypothesis that the glomerular changes parallel proximal tubule dysfunction in the early stages of diabetic nephropathy.

Purpose: Limited data exist on the use of statins in Chinese patients with coronary artery disease (CAD) treated with percutaneous coronary intervention (PCI). We therefore conducted this study to observe the usage trend and the effectiveness of statins on LDL-C goal attainment and other lipid parameters among PCI-treated patients., Methods: This multicenter, retrospective, observational, longitudinal cohort study was conducted in PCI-treated patients with CAD between July 1, 2011, and February 28, 2015. Primary study outcomes included statin treatment pattern after PCI and proportion of patients achieving target (LDL-C) levels 1 month after PCI and initiating statin therapy., Findings: Data were analyzed for 2708 patients (mean age, 59 [10] years; median body mass index, 25.6 [4.0] kg/m 2 ). From baseline to the end of 1 month, atorvastatin and rosuvastatin were the most prescribed statins; 20 mg and 10 mg were the most prescribed doses and therefore chosen for efficacy comparisons. In patients without dose changes, LDL-C reduction with rosuvastatin 10 mg was significantly greater compared with atorvastatin 20 mg (-0.67 mmol/L [from 2.44 mmol/L to 1.77 mmol/L] vs -0.54 mmol/L [from 2.40 mmol/L to 1.86 mmol/L]; P = 0.008). However, there was no difference in HDL-C, triglyceride, or total cholesterol values between groups. Age and LDL-C levels at baseline were significantly associated with target LDL-C achievement., Implications: In real-world, PCI-treated Chinese patients, atorvastatin and rosuvastatin were the most prescribed statins. Compared with atorvastatin 20 mg, rosuvastatin 10 mg was associated with greater LDL-C reductions and achievement of LDL-C targets in a higher percentage of patients. This analysis of real-world data shows that both rosuvastatin and atorvastatin were well tolerated and seemed to be suitable drugs for controlling lipid levels and preventing CVD risk in post-PCI Chinese patients with CAD., (Copyright © 2017.

Importance: High-intensity statins are recommended following myocardial infarction. However, patients may not continue taking this medication with high adherence., Objective: To estimate the proportion of patients filling high-intensity statin prescriptions following myocardial infarction who continue taking this medication with high adherence and to analyze factors associated with continuing a high-intensity statin with high adherence after myocardial infarction., Design, Setting, and Participants: Retrospective cohort study of Medicare patients following hospitalization for myocardial infarction. Medicare beneficiaries aged 66 to 75 years (n = 29 932) and older than 75 years (n = 27 956) hospitalized for myocardial infarction between 2007 and 2012 who filled a high-intensity statin prescription (atorvastatin, 40-80 mg, and rosuvastatin, 20-40 mg) within 30 days of discharge. Beneficiaries had Medicare fee-for-service coverage including pharmacy benefits., Exposures: Sociodemographic, dual Medicare/Medicaid coverage, comorbidities, not filling high-intensity statin prescriptions before their myocardial infarction (ie, new users), and cardiac rehabilitation and outpatient cardiologist visits after discharge., Main Outcomes and Measures: High adherence to high-intensity statins at 6 months and 2 years after discharge was defined by a proportion of days covered of at least 80%, down-titration was defined by switching to a low/moderate-intensity statin with a proportion of days covered of at least 80%, and low adherence was defined by a proportion of days covered less than 80% for any statin intensity without discontinuation. Discontinuation was defined by not having a statin available to take in the last 60 days of each follow-up period., Results: Approximately half of the beneficiaries were women and fourth-fifths were white. At 6 months and 2 years after discharge among beneficiaries 66 to 75 years of age, 17 633 (58.9%) and 10 308 (41.6%) were taking high-intensity statins with high adherence, 2605 (8.7%) and 3315 (13.4%) down-titrated, 5182 (17.3%) and 4727 (19.1%) had low adherence, and 3705 (12.4%) and 4648 (18.8%) discontinued their statin, respectively. The proportion taking high-intensity statins with high adherence increased between 2007 and 2012. African American patients, Hispanic patients, and new high-intensity statin users were less likely to take high-intensity statins with high adherence, and those with dual Medicare/Medicaid coverage and more cardiologist visits after discharge and who participated in cardiac rehabilitation were more likely to take high-intensity statins with high adherence. Results were similar among beneficiaries older than 75 years of age., Conclusions and Relevance: Many patients filling high-intensity statins following a myocardial infarction do not continue taking this medication with high adherence for 2 years postdischarge. Interventions are needed to increase high-intensity statin use and adherence after myocardial infarction.

In patients with ischemic heart disease and type 2 diabetes mellitus in 4-6 weeks after acute coronary syndrome (ACS) on stable dual antiplatelet therapy (DAPT) with aspirin and clopidogrel co-adminstrated with rosuvastatin residual platelet reactivity on adenosine diphosphate was higher than in patients receiving atorvastatin. However, the rate of high residual on-clopidogrel treatment platelet reactivity (RCPR) in rosuvastatin-treated patients exceeded the rate of high RCPR in atorvastatin-treated patients insignificantly. In 6 months after ACS residual platelet reactivity did not differ between the groups. After 12 months of DAPT platelet reactivity increased as compared to baseline values both in patients receiving rosuvastatin and in patients receiving atorvastatin without switching. In patients, randomly switching from one statin type to another at 6 month of treatment, platelet reactivity did not change significantly in comparison to baseline and the prevalence of high RCPR was lower than in patients receiving statins without switching. Thus, in patients with diabetes with ACS on DAPT with acetylsalicylic acid and clopidogrel statin treatment should be started with atorvastatin and in 6 months after ACS atorvastatin should be switched to rosuvastatin. This approach will provide lower RCPR within at least first 4-6 weeks after ACS and prevent RCPR increase during 12 months of DATT use in this patients group.

Objective: Oxidative stress is increased in patients with acute myocardial infarction (AMI). Statins reduce oxidative stress independent of their effect in reducing low-density lipoprotein cholesterol (LDL-C). The aim of the present study was to compare the effects of atorvastatin and rosuvastatin on oxidative status by investigating serum paraoxonase, serum arylesterase, total oxidant status, total antioxidant status (TAS) and oxidative stress index (OSI) in patients with AMI., Methods: Seventy patients with AMI were randomized into 2 groups; total of 55 patients (19 females, 36 males) aged 32 to 86 years completed the study and were included in the analysis. Patients were treated with 80 mg atorvastatin or 40 mg rosuvastatin for 4 weeks. Lipid parameters and parameters of oxidative status were measured at admission and after 4-week statin treatment., Results: After 4-week treatment, atorvastatin and rosuvastatin were associated with significant reduction in TAS, OSI, total cholesterol, and LDL-C levels. Serum paraoxonase level was significantly increased in both groups, while high-density lipoprotein cholesterol (HDL-C) level was significantly reduced in atorvastatin group. No statistically significant differences were found between atorvastatin and rosuvastatin in terms of actual difference in oxidative stress parameters., Conclusion: Atorvastatin and rosuvastatin have similar effects on oxidative status in patients with AMI. Rosuvastatin affected HDL-C level more favorably than atorvastatin.

Background: Statins are one of the lipid-lowering drugs that help in reducing cholesterol levels in the body by specifically inhibiting 3-hydroxy-3-methylglutaryl coenzyme A reductase, which is a rate-limiting enzyme for cholesterol synthesis. Rosuvastatin (RSV) and atorvastatin (ATV) have shown bone stimulatory and anti-inflammatory effects. The present study aims to explore efficacy of 1.2% RSV and 1.2% ATV gels as a local drug delivery and redelivery system adjunct to scaling and root planing (SRP) for treatment of Class II furcation defects., Methods: Ninety patients with mandibular buccal Class II furcation defects were randomly allocated to three treatment groups: 1) SRP with placebo gel (group 1); 2) SRP with 1.2% RSV gel (group 2); and 3) SRP with 1.2% ATV gel (group 3). Clinical and radiographic parameters were recorded at baseline and after 6 months. Gels were redelivered at the respective sites at a 6-month recall appointment. All clinical and radiographic parameters were recorded again after 3 months (i.e., 9 months from baseline)., Results: Greater mean probing depth (PD) reduction and greater mean gain in relative vertical clinical attachment level (CAL) and relative horizontal CAL were seen in the RSV group than in the ATV group at 6 and 9 months. Significantly greater mean percentage of defect depth reduction (DDR) was found in the RSV group (30.80% ± 8.35%, 41.86% ± 6.76%) than in the ATV group (25.54% ± 8.89%, 34.31% ± 8.04%) at 6 and 9 months, respectively., Conclusion: The RSV group shows significant improvement in all clinical parameters and significantly greater DDR compared with the ATV group in treatment of mandibular Class II furcation defects as an adjunct to SRP.

Background and Aims: High plasma LDL-cholesterol (LDL-C) and platelet responses have major pathogenic roles in atherothrombosis. Thus, statins and anti-platelet drugs constitute mainstays in cardiovascular prevention/treatment. However, the role of platelet tissue factor-dependent procoagulant activity (TF-PCA) has remained unexplored in hypercholesterolemia. We aimed to study platelet TF-PCA and its relationship with membrane cholesterol in vitro and in 45 hypercholesterolemic patients (HC-patients) (LDL-C >3.37 mmol/L, 130 mg/dL) and 37 control subjects (LDL-C <3.37 mmol/L). The effect of 1-month administration of 80 mg/day atorvastatin (n = 21) and 20 mg/day rosuvastatin (n = 24) was compared., Methods: Platelet TF-PCA was induced by GPIbα activation with VWF-ristocetin., Results: Cholesterol-enriched platelets in vitro had augmented aggregation/secretion and platelet FXa generation (1.65-fold increase, p = 0.01). HC-patients had 1.5-, 2.3- and 2.5-fold increases in platelet cholesterol, TF protein and activity, respectively; their platelets had neither hyper-aggregation nor endogenous thrombin generation (ETP). Rosuvastatin, but not atorvastatin, normalized platelet cholesterol, TF protein and FXa generation. It also increased slightly the plasma HDL-C levels, which correlated negatively with TF-PCA., Conclusions: Platelets from HC-patients were not hyper-responsive to low concentrations of classical agonists and had normal PRP-ETP, before and after statin administration. However, washed platelets from HC-patients had increased membrane cholesterol, TF protein and TF-PCA. The platelet TF-dependent PCA was specifically expressed after VWF-induced GPIbα activation. Rosuvastatin, but not atorvastatin treatment, normalized the membrane cholesterol, TF protein and TF-PCA in HC-patients, possibly unveiling a new pleiotropic effect of rosuvastatin. Modulation of platelet TF-PCA may become a novel target to prevent/treat atherothrombosis without increasing bleeding risks., (Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.)

Background: To assess changes in the treatment of hypercholesterolemia in Polish ambulatory care over the last 6 years., Methods: Data were obtained from two separate questionnaire-based studies, conducted in 2009 and 2015. The analysis included only those patient visits, which were associated with modifications of previous hypercholesterolemia treatment (1924 visits from the year 2009 and 1888 visits from the year 2015)., Results: In the present registry, there was a 19 mg/dL reduction in the level of total cholesterol and a 17 mg/dL reduction in the level of low-density lipoprotein compared to year 2009. In both registries, the most common reason for treatment modification was failure to achieve therapeutic goals. Compared to year 2009, there was an increase in the proportion of patients treated with atorvastatin and a reduction in the proportion of patients treated with simvastatin at baseline; additionally, in year 2015, 10% of patients received rosuvastatin. After therapy modification, there was a similar increase in the proportion of patients treated with a statin-fibrate combination in both registries. However, at present, ezetimibe was significantly less often added to previous therapy. In both registries, therapy modification led to an increase in the mean doses of the most commonly used statins, although presently, this increase was smaller than in 2009., Conclusions: The most favorable change in the treatment of hypercholesterolemia is an increase in the proportion of patients treated with strong statins. Unfavorable changes include a reduction in the frequency of polytherapy, especially with ezetimibe, and a tendency to prescribe lower, ineffective statin doses.

Background: The November 2013 American College of Cardiology/American Heart Association cholesterol guidelines recommend the use of high-intensity statins for patients with atherosclerotic cardiovascular disease (ASCVD). We sought to determine how these guidelines are being adopted at the Veterans Affairs (VA) Health System and identify treatment gaps., Methods: We examined administrative data from the VA 12 months prior to the index dates of April 1, 2013, and after April 1, 2014, to identify patients ≤75 years of age with ≥2 codes for ASCVD. We identified those on high-intensity statin therapy (atorvastatin 40 mg or 80 mg, rosuvastatin 20 mg or 40 mg, and simvastatin 80 mg) during the 6 months after the index date., Results: The study sample included 331,927 and 326,759 eligible adults with ASCVD before and after the release of the new guidelines, respectively. Overall, high-intensity statin use increased from 28% to 35% after guideline release. High-intensity statin use was lowest in Hispanics and Native Americans, although all groups showed an increase over time. Among those on low- or moderate-intensity statin therapy, 15.6% were intensified to a high-intensity statin after guideline release. Groups less likely to undergo statin intensification were older adults (odds ratio=0.78 for each 10-year increase, 95% CI 0.76-0.81), women (odds ratio=0.86, 95% CI 0.75-0.99), and certain minority groups. Academic teaching hospitals and hospitals on the West Coast were more likely to intensify statins after release of the new guidelines., Conclusions: High-intensity statin use increased in the VA following release of the American College of Cardiology/American Heart Association cholesterol treatment guidelines, although disparities persist for certain patient groups including older adults, women, and certain minority groups., (Published by Elsevier Inc.)

Background: Cost sharing is widely used to encourage therapeutic substitution. This study aimed to examine the impact of increases in patient cost-sharing differentials for brand name and generic drugs on statin utilization on entry into the Medicare Part D coverage gap., Method and Results: Using 5% Medicare Chronic Condition Warehouse files from 2006, this quasi-experimental study examined patients with hyperlipidemia who filled prescriptions for atorvastatin or rosuvastatin between January and March 2006. Propensity score matching and difference-in-difference regressions were used to compare changes in statin utilization for the study group (patients who were not eligible for low-income subsidies [non-LIS] and had generic-only gap coverage) to those of a control group (LIS patients who faced the same cost sharing before and during the Part D coverage gap). In the final sample, 801 patients in the study group were matched to 801 patients in the control group. We found that, compared to the control group, the study group had a larger decline in any monthly brand-name statin use (-0.24 30-day fills, P<0.001). This was only partially offset by increased monthly generic statin use (+0.06 30-day fill, P<0.001), with an overall drop in any monthly statin use (-0.18 30-day fills, P<0.001). Overall adherence with statins declined (OR 0.81, P<0.001), and statin discontinuation increased (OR 1.62, P<0.001) in the study group as compared to the control group., Conclusions: Increases in cost-sharing differentials for brand name and generic drugs on coverage gap entry were associated with discontinuation of statins in Medicare Part D patients with hyperlipidemia., (© 2016 The Authors.

Purpose: Whether statins improve arteriovenous fistula (AVF) outcomes is still a matter of debate. Taking into consideration the existing physicochemical differences between individual drugs, this study evaluates the impact of three different statins (atorvastatin, rosuvastatin and simvastatin) on one-stage and two-stage AVF outcomes., Methods: Using a retrospective cohort of 535 patients, we analyzed the effects of each statin on primary failure and primary patency using multivariate logistic regressions and Cox proportional hazard models., Results: Out of the three statins analyzed, only atorvastatin improved the overall primary failure of AVF (odds ratio [OR] = 0.18, p = 0.005). Comparisons between the two AVF types demonstrated that this effect was due to a prominent reduction in primary failure of one-stage (OR = 0.03; p = 0.005), but not two-stage fistulas (OR = 0.43; p = 0.25). In contrast, primary patency of two-stage (hazards ratio [HR] = 0.51; p = 0.024), but not one-stage fistulas (HR = 0.98; p = 0.95), was improved by all statins as a group, but not by individual drugs., Conclusions: Our results suggest that the potential benefit of statins on AVF outcomes is a drug-specific and not a class effect, and that such effect is also influenced by the type of fistula.

Background: The 2013 American College of Cardiology/American Heart Association cholesterol management guidelines represented a paradigm shift from the National Cholesterol Education Program Adult Treatment Panel III guidelines, replacing low-density lipoprotein cholesterol targets with a risk assessment model to guide statin therapy. Our objectives are to compare provider prescription of high-intensity statin therapy in patients hospitalized with acute coronary syndrome (ACS) or cerebrovascular accident (CVA) before and after the publication of the 2013 cholesterol guidelines, determine potential predictors of high-intensity statin utilization, and identify targets for improvement in cardiovascular risk reduction among these high-risk populations., Methods: A single-center retrospective cohort study of 695 patients discharged with a diagnosis of ACS or CVA in the 6months before (n=359) and after (n=336) the release of the 2013 American College of Cardiology/American Heart Association cholesterol guidelines. Patient characteristics were compared using analysis of variance and χ 2 tests. Multivariable logistic regression models were used to assess clinical predictors of provider utilization of high-intensity statins., Results: After the 2013 cholesterol guidelines, the rate of prescribing high-intensity statins was greater for statin-naïve patients compared with those already on statin therapy (odds ratio [OR]0.51, P=.02). Prescription of high-intensity statins was higher for patients with ACS compared with CVA (OR 8.4, P<.001-pre-2013 guidelines; OR 4.5, P<.001-post-2013 guidelines). Prescription of high-intensity statins steadily improved over the study period, significantly among patients with CVA (P<.001)., Conclusions: Physicians were more likely to prescribe high-intensity statins in statin-naïve patients as compared with intensifying existing statin therapy, and their prescription pattern was lower after CVA vs ACS., (Copyright © 2016 Elsevier Inc.

Aims: Patient response to statin treatment is individual and varied. As a consequence, when using a specific-dose approach, as recommended in the 2013 American College of Cardiology/American Heart Association guideline, there will be a range of reductions in the concentration of low-density lipoprotein cholesterol (LDL-C). The aim of this study was to use individual patient data from the VOYAGER meta-analysis to determine the extent of the variability in LDL-C reduction in response to treatment across the recommended doses of different statins., Methods and Results: The percentage change from baseline in LDL-C was calculated using individual subject data collected from 32 258 patients treated with atorvastatin 10-80 mg, rosuvastatin 5-40 mg, or simvastatin 10-80 mg. The percentage change in LDL-C for each patient was then used to generate waterfall plots that demonstrated the extent of the variability in response to treatment at all doses of the three statins. The standard deviation of LDL-C reduction for all statins and doses ranged from 12.8 to 17.9%. The percentage of patients experiencing a suboptimal response (<30% reduction in LDL-C) ranged from 5.3 to 53.3%., Conclusion: These results indicate that there is considerable individual variation in the LDL-C reduction at all doses of simvastatin, atorvastatin, and rosuvastatin., (Published on behalf of the European Society of Cardiology.

This study was designed to characterize the potential therapeutic effects of two statin drugs commonly used to treat dyslipidemia in inflammation-linked metabolic disorders related to type 2 diabetes. Atorvastatin (10 mg/kg/day) and rosuvastatin (3 mg/kg/day) were administered to mice with diet-induced obesity (DIO). The statins lowered serum total and LDL cholesterol levels, and improved the atherogenic index and cardiac risk index. Furthermore, the drugs decreased fasting glucose levels, improved glucose tolerance, and decreased fat tissue weight and adipocyte size; this was accompanied by an overall body weight loss tendency. The statins also improved antigen-specific immunity. The killing activity of cytotoxic T cells and exacerbation of IgG secretion levels were considerably normalized. Most importantly, serum tumor necrosis factor-α and interleukin 6 levels decreased, while their RNA expression levels in fat tissue were regulated by the statins as well. This study is the first to indicate that low doses of atorvastatin and rosuvastatin, the dosing regimen for which has been controversial, could significantly improve diabetes-related metabolic disorders, and could modulate pro-inflammatory cytokines, alleviating inflammation and simultaneously restoring overall humoral and cell-mediated immunity., (Copyright © 2016 Elsevier Inc.

Background: There are little evidences about the therapeutic efficacy of different lipid-lowering agents in the reduction of elevated lipoprotein(a) [Lp(a)]., Objective: testing the effect of different lipid-lowering agents on elevated Lp(a)., Methods: prospective interventional study performed in patients with CAD, or high CAD risk, with Lp(a), >50 mg/dL. Lp(a), total cholesterol (C), HDL-C, LDL-C, triglycerides (TGs), apolipoprotein (Apo) A1, Apo B, enzymes of myocyte and hepatic injury were comparatively analyzed between 4 lipid-lowering strategies: rosuvastatin (R group) 40 mg, atorvastatin (A group) 80 mg, atorvastatin 40 mg add-on micronized fenofibrate (A+F group), and atorvastatin 40 mg add-on 1 g extended-release niacin (A+ERN group). Comparison was made for their therapeutic efficacy on Lp(a), and safety., Results: 87 patients with mean Lp(a) 94.6 ± 39.6 mg/dL were analyzed. Groups: 25 patients in the R, 22 in the A, 20 in the A+F and 20 in A+ERN group. Significant reduction in all lipid fractions in all treatment groups was reported after 6 months. The average reduction of Lp(a) was 15.9 ± 21.0 mg/dL, with: 18.2 ± 24.8 (P = 0.001) in the R group, 17.3 ± 10.4 (P = 0.001) in A+F, 19.5 ± 10.9 (P = 0.001) in A+ERN and the lowest in the A group (11.24 ± 22.91, P = 0.032). No adverse effects were observed in any of the treatment groups., Conclusions: When compared with atorvastatin, it seems that rosuvastatin can achieve more significant decrease of Lp(a).The efficacy of the second one can be increased by adding fibrate or ERN., (© The Author(s) 2016.)

Background: Statins (3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors) are an important group of hypolipidemic drugs that are able to modulate inflammation and alveolar bone loss. Rosuvastatin (RSV) and atorvastatin (ATV) are known to inhibit osteoclastic bone resorption and have been proposed to have osteostimulative properties. The aim of this study is to evaluate and compare the efficacy of 1.2% RSV and 1.2% ATV gel local drug delivery (LDD) and redelivery systems, in addition to scaling and root planing (SRP), for the treatment of intrabony defects (IBDs) in patients with chronic periodontitis (CP)., Methods: A total of 90 individuals with 90 IBDs was randomly allocated to treatment with SRP followed by LDD of 1.2% RSV, 1.2% ATV, or placebo gel. Clinical and radiographic parameters, including plaque index (PI), modified sulcus bleeding index (mSBI), probing depth (PD), clinical attachment level (CAL), and IBD depth, were recorded at baseline and 6 and 9 months., Results: All three groups showed significant reduction in PI and mSBI at all intervals. Mean mSBI and PD reductions, CAL gain, and IBD depth reduction with statin drugs were significantly greater than with placebo gel LDD. Improvements in these parameters were significantly greater with RSV LDD than ATV or placebo gels at 6 and 9 months., Conclusion: LDD of 1.2% RSV results in significantly greater clinico-radiographic improvement than 1.2% ATV or placebo gels as adjunct to mechanical periodontal therapy.

We conducted a meta-analysis of 13 randomized trials comparing the efficacy of rosuvastatin versus atorvastatin in reducing concentrations of C-reactive protein (CRP). We searched PubMed, Ovid, and Elsevier databases until June 2014. Search terms included C-reactive protein or CRP, rosuvastatin, atorvastatin, randomized, randomly, and randomization; 13 trials (3798 patients) were included. Funnel plots for CRP were inspected to assess publication bias. The pooled analysis demonstrated the benefit of rosuvastatin over atorvastatin therapy for all 13 trials (mean difference [MD] = -0.11, which is standardized mean with no unit although the raw data before pooling is mg/L, 95% confidence interval -0.15 to -0.07, P < .0001) with no evidence of significant publication bias (I(2) = 6.9%, P = .377). Subgroup analysis indicated a significant benefit of rosuvastatin over atorvastatin regarding the 1/1 dose ratio (MD = -0.14, 95% CI -0.21 to -0.06) and 1/2 dose ratio (MD= -0.11, 95% CI -0.16 to -0.05). Cumulative and influence analyses showed accuracy and stability for the estimation mentioned earlier. Our meta-analysis shows that rosuvastatin produces better reduction in CRP concentrations than atorvastatin at a dose ratio of 1/1 and 1/2 (rosuvastatin/atorvastatin), respectively., (© The Author(s) 2015.)

Background: Achieving the greatest reduction in atherogenic lipoproteins requires the optimum dose and potency of statin. Using data from the VOYAGER meta-analysis, we determined doses of rosuvastatin, atorvastatin and simvastatin that induce equal reductions in low-density lipoprotein cholesterol (LDL-C) and non-high-density lipoprotein cholesterol (non-HDL-C)., Methods: Least squares mean percentage change in LDL-C and non-HDL-C was calculated using 38,052 patient exposures to rosuvastatin 5-40 mg, atorvastatin 10-80 mg and simvastatin 10-80 mg. Equipotent doses were estimated by linear interpolation between actual adjacent doses., Results: Rosuvastatin 5 mg reduced LDL-C by 39% and non-HDL-C by 35%. Equivalent reductions in LDL-C required atorvastatin 15 mg or simvastatin 39 mg. Equivalent reductions in non-HDL-C required atorvastatin 14 mg or simvastatin 42 mg. Rosuvastatin 10 mg reduced LDL-C by 44% and non-HDL-C by 40%. Equivalent reductions in LDL-C required atorvastatin 29 mg or simvastatin 72 mg. Equivalent reductions in non-HDL-C required atorvastatin 27 mg or simvastatin 77 mg. Rosuvastatin 20 mg reduced LDL-C by 50% and non-HDL-C by 45%. Equivalent reductions in LDL-C and non-HDL-C required atorvastatin 70 mg and atorvastatin 62 mg, respectively, and were not achieved with the maximum 80 mg dose of simvastatin. Rosuvastatin 40 mg reduced LDL-C by 55% and non-HDL-C by 50%. Comparable reductions were not achieved with the maximum 80 mg doses of atorvastatin or simvastatin., Conclusions: Regarding reductions in LDL-C and non-HDL-C, each rosuvastatin dose is equivalent to doses 3-3.5 times higher for atorvastatin and 7-8 times higher for simvastatin., (© The European Society of Cardiology 2015.)

Aims: This open-label, randomized, parallel-group comparative study compared the efficacy of rosuvastatin (5mg/day) and atorvastatin (10mg/day) for reduction of small dense low-density lipoprotein cholesterol (sd LDL-C) levels in Japanese patients with type 2 diabetes mellitus (T2DM)., Methods: Patients with T2DM and hypercholesterolemia with detectable sd LDL-C after receiving 10mg/day atorvastatin for ≥ 24 weeks were randomly assigned to receive rosuvastatin (5mg/day; switched treatment) or atorvastatin (10mg/day; continued treatment) for 12 weeks. The primary endpoints were changes in sd LDL-C levels and sd LDL-C/total LDL-C ratio evaluated using the LipoPhor AS(®) system., Results: There were no significant percent changes from baseline for LDL-C levels between the switched (n=55) and the continued treatment group (n=56). However, the former group exhibited a statistically significant reduction from baseline of sd LDL-C levels, sd LDL-C/total LDL-C ratio compared with the latter group (-3.8 mg/dL vs. -1.4 mg/dL, p=0.014; -2.3% vs. -0.6%, p=0.004, respectively). Multiple regression analysis among all subjects revealed that independent factors contributing to the reduction in sd LDL-C levels were a change in LDL-C (p=0.003) and triglyceride (TG) levels (p=0.006), treatment group (the switched group=1, the continued group=0; standard coefficient=-1.2, p=0.034) and baseline glycated hemoglobin A1c (HbA1c) (p=0.045), respectively., Conclusion: Switching from 10mg atorvastatin to 5mg rosuvastatin may be a useful therapeutic option to reduce sd LDL-C levels in Japanese hypercholesterolemic patients with T2DM., (Copyright © 2015 Elsevier Ireland Ltd.

Background: Residual high-on treatment platelet reactivity (HRPR) still represents a challenging matter in patients with coronary artery disease. Drug-to-drug interaction has been suggested between some statin and antiplatelet agents, despite their co-administration is mandatory in patients after an acute cardiovascular event or coronary stenting. Therefore, the aim of the current study was to investigate any impact of rosuvastatin or atorvastatin co-administration on platelet reactivity in patients receiving dual antiplatelet therapy (DAPT)., Methods: Our population is represented by patients on DAPT (ASA and either clopidogrel 75 mg or ticagrelor 90 mg b.i.d) after an ACS or percutaneous revascularization, and receiving rosuvastatin or atorvastatin. Platelet function was assessed by Multiplate Impedance Aggregometry (Roche Diagnostics AG)., Results: We included a total of 374 patients, 240 (64.2%) receiving atorvastatin, 134 (35.8%) rosuvastatin. Rosuvastatin treated patients were more often using beta-blockers (p = 0.05), diuretics (p = 0.04) and displayed higher HDL (p < 0.001) and lower LDL cholesterol (p < 0.001). The prevalence of HRPR for ASA was low, with no difference according to statin type (0.8% vs 1.5%, p = 0.62, adjusted OR[95%CI] = 2[0.23-16.6], p = 0.52). Concerning ADP-antagonists, in the 163 patients treated with clopidogrel, rosuvastatin co-administration was associated with a significantly increased rate of HRPR (55.6%vs 32%, p = 0.01, adjusted OR[95%CI] = 2.69[1.22-5.96], p = 0.015) with higher ADP-mediated platelet reactivity (p = 0.01) and TRAP-test results (p = 0.04). On the contrary, in the 211 ticagrelor treated patients, statin type did not affect mean platelet reactivity or the prevalence of HRPR with ticagrelor (10.5% vs 11.2%, p = 0.99, adjusted OR[95%CI] = 0.86[0.34-2.22], p = 0.76) CONCLUSIONS: Among patients receiving DAPT, rosuvastatin but not atorvastatin is associated with an increased rate of HRPR for clopidogrel, without any influence on the antiplatelet effect of ASA or ticagrelor. Therefore, cautiousness should be exerted for clopidogrel and rosuvastatin therapeutic association., (Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.)
