There is a paucity of data regarding the safety of a 1-month dual antiplatelet therapy (DAPT) after percutaneous coronary intervention (PCI) in patients at high bleeding risk (HBR) presenting with acute coronary syndromes (ACS). We aimed to compare the clinical outcomes of patients at HBR with chronic coronary syndrome (CCS) or ACS treated with PCI using bioresorbable polymer everolimus-eluting stent (BP-EES) followed by 1-month DAPT. Patients at HBR who underwent PCI with BP-EES were prospectively enrolled in 10 Italian centers. All patients were treated with 1-month DAPT. In case of need for anticoagulation, patients received an oral anticoagulant in addition to a P2Y12 inhibitor for 1 month, followed by oral anticoagulation only after that. The primary end point was a composite of cardiac death, myocardial infarction, or definite/probable stent thrombosis at 12 months. Overall, 263 patients (59.4%) with CCS and 180 patients (40.6%) with ACS were enrolled. No significant difference was evident between patients with CCS and ACS for the primary end point (4.3% vs 5.6%, respectively, p = 0.497) and for each isolated component. The risk for Bleeding Academic Research Consortium (BARC) type 1 to 5 or type 3 to 5 bleedings was also similar between patients with CCS and ACS (4.3% vs 5.2%, p = 0.677, and 1.6% vs 2.9%, p = 0.351, respectively). In conclusion, among HBR patients with ACS who underwent PCI with BP-EES, a 1-month DAPT strategy is associated with a similar risk of ischemic and bleeding events compared with those with CCS., Competing Interests: Declaration of Competing Interest Dr. Testa has received consulting fees, personal and institutional honoraria, and has served on the advisory board participation from Abbott, Medtronic, Biotronik, Boston Scientific Corporation, Terumo Lifesciences, Meril, Cardionovum, Concept Medical.

Introduction: For acute coronary syndrome (ACS) patients treated with percutaneous coronary intervention (PCI), the choice of the duration and kind of dual antiplatelet therapy (DAPT) offering the most accurate balance between ischemic and bleeding risk remains unknown., Evidence Acquisition: A network meta-analysis was performed including all Randomized Controlled Trials (RCTs) comparing different DAPT regimens and duration in ACS patients undergoing PCI. Trial-defined MACE and major bleedings were the primary endpoints. Stroke, stent thrombosis (ST), all-cause and cardiovascular death, myocardial infarction (MI) represented secondary endpoints., Evidence Synthesis: 13 RCTs encompassing 46145 patients were included. Mean age was 62 (61-64) years old, 42% being admitted with STEMI, 33% with NSTEMI and 25% with UA. The competitive arms were: clopidogrel and aspirin for 12 months (6 arms/18183 patients), clopidogrel and aspirin for 6 months (4/3329), clopidogrel and aspirin >12 months (3/2238), ticagrelor and aspirin for 12 months (6/12942) and prasugrel and aspirin for 12 months (3/9453). Trial-defined MACE and major bleedings, stroke and death were similar among the different arms. DAPT with prasugrel and aspirin for 12 months reduced MI compared to aspirin and clopidogrel for 12 months (OR 0.71, 95% CI: 0.54.0.94) and reduced the risk of ST compared to ticagrelor (OR 0.66, 95% CI: 0.49-0.90). Both prasugrel and ticagrelor reduced ST as compared to clopidogrel and aspirin for 12 months., Conclusions: Different DAPT strategies yield similar risk of MACE, major bleeding, death and stroke in ACS patients. Prasugrel and aspirin for 12 months proved to be the most effective strategy regarding ST and MI.

Background: Patients with previous acute coronary syndrome (ACS) are at high risk of recurrent adverse cardiovascular events. Recently, prolonged dual antiplatelet therapy (DAPT) and oral anticoagulation therapy (OAT) have been shown to reduce recurrent ischemic events to the expense of an increase in bleeding events. The number of patients potentially eligible for these therapies in real life remains to be determined., Methods: Among ACS patients from five registries and one randomized controlled trial, we assessed the proportion of patients eligible for the PEGASUS strategy only and the proportion of patients eligible for the COMPASS strategy only, and set out the proportion of patients with an overlap between the strategies., Findings: Among the 10,048 evaluable patients, we found that 5373 (53.4%) were eligible for the PEGASUS strategy and 3841 (38.2%) were eligible for the COMPASS strategy, with a group of 3444 (34.4%) overlapping between the two strategies. The number of patients eligible for the PEGASUS strategy only was 1929 (19.2%) and the number eligible for the COMPASS strategy only was 397 (4.0%); 4278 (42.6%) were eligible for neither a PEGASUS strategy nor a COMPASS strategy., Interpretation: In a large cohort of ACS patients, one in three patients was eligible for either a prolonged DAPT with ticagrelor 60 mg and low-dose aspirin or a dual pathway inhibition approach with rivaroxaban 2.5 mg and low-dose aspirin., (© 2022.

Aims: To establish the safety and efficacy of different dual antiplatelet therapy (DAPT) combinations in patients with acute coronary syndrome (ACS) according to their baseline ischaemic and bleeding risk estimated with a machine learning derived model [machine learning-based prediction of adverse events following an acute coronary syndrome (PRAISE) score]., Methods and Results: Incidences of death, re-acute myocardial infarction (re-AMI), and Bleeding Academic Research Consortium 3-5 bleeding with aspirin plus different P2Y12 inhibitors (clopidogrel or potent P2Y12 inhibitors: ticagrelor or prasugrel) were appraised among patients of the PRAISE data set grouped in four subcohorts: low-to-moderate ischaemic and bleeding risk; low-to-moderate ischaemic risk and high bleeding risk; high ischaemic risk and low-to-moderate bleeding risk; and high ischaemic and bleeding risk. Hazard ratios (HRs) for the outcome measures were derived with inverse probability of treatment weighting adjustment. Among patients with low-to-moderate bleeding risk, clopidogrel was associated with higher rates of re-AMI in those at low-to-moderate ischaemic risk [HR 1.69, 95% confidence interval (CI) 1.16-2.51; P = 0.006] and increased risk of death (HR 3.2, 1.45-4.21; P = 0.003) and re-AMI (HR 2.23, 1.45-3.41; P < 0.001) in those at high ischaemic risk compared with prasugrel or ticagrelor, without a difference in the risk of major bleeding. Among patients with high bleeding risk, clopidogrel showed comparable risk of death, re-AMI, and major bleeding vs. potent P2Y12 inhibitors, regardless of the baseline ischaemic risk., Conclusion: Among ACS patients with non-high risk of bleeding, the use of potent P2Y12 inhibitors is associated with a lower risk of death and recurrent ischaemic events, without bleeding excess. Patients deemed at high bleeding risk may instead be safely addressed to a less intensive DAPT strategy with clopidogrel., (© The Author(s) 2022.

Background: The safety and efficacy of potent P2Y12 inhibitors (Ticagrelor and Prasugrel) in dual antiplatelet therapy (DAPT) with aspirin in elderly acute coronary syndrome (ACS) patients remains unclear., Methods: All ACS patients aged 75 years and older treated with Percutaneous Coronary Intervention (PCI) from PRAISE dataset were included. The safety and efficacy of Ticagrelor vs Clopidogrel was evaluated with inverse probability of treatment weighting (IPTW). Sensitivity analysis was performed for patients older or equal than 85 years old. All-cause mortality was the primary endpoint, while myocardial infarction (MI), Bleeding Academic Research Consortium (BARC) 3-5 bleedings and Major and Net Adverse Clinical and Cardiac Events (MACE and NACE) were the secondary ones., Results: 4287 patients were included, 3197 treated with Clopidogrel and 1090 with Ticagrelor. After 16 ± 3 months, Ticagrelor showed neutral effect on NACE and mortality (HR 0.98; 0.63-1.52, p = 0.94 and HR 0.38; 0.14-1.04, p = 0,06), reduced risk of MACE and MI (HR 0.82; 0.23-0.91, p = 0.03 and HR 0.43; 0.14-0.89, p = 0.04) and increased risk of BARC 3-5 bleeding (HR 2.14; 1.19-3.85, p = 0.001). In very elderly patients (≥85 years) Ticagrelor decreased risk of MI and increased risk of bleeding (HR 0.69; 0.22-0.95, p = 0.04 and HR 2.36; 1.02-5.52, p = 0.04, all 95%CI) with neutral effect on NACE and MACE., Conclusions: In elderly ACS patients treated with PCI, Ticagrelor was associated with neutral effect on all-cause mortality, lower risk MACE and MI compared with Clopidogrel. Such benefit was counterbalanced by increased risk of major bleedings. These results were consistent among patients aged 85 years and older., (Copyright © 2022 Elsevier B.V. All rights reserved.)

Optimal dual antiplatelet therapy (DAPT) duration for patients undergoing percutaneous coronary intervention (PCI) for coronary bifurcations is an unmet issue. The BIFURCAT registry was obtained by merging two registries on coronary bifurcations. Three groups were compared in a two-by-two fashion: short-term DAPT (≤ 6 months), intermediate-term DAPT (6-12 months) and extended DAPT (>12 months). Major adverse cardiac events (MACE) (a composite of all-cause death, myocardial infarction (MI), target-lesion revascularization and stent thrombosis) were the primary endpoint. Single components of MACE were the secondary endpoints. Events were appraised according to the clinical presentation: chronic coronary syndrome (CCS) versus acute coronary syndrome (ACS). 5537 patients (3231 ACS, 2306 CCS) were included. After a median follow-up of 2.1 years (IQR 0.9-2.2), extended DAPT was associated with a lower incidence of MACE compared with intermediate-term DAPT (2.8% versus 3.4%, adjusted HR 0.23 [0.1-0.54], p <0.001), driven by a reduction of all-cause death in the ACS cohort. In the CCS cohort, an extended DAPT strategy was not associated with a reduced risk of MACE. In conclusion, among real-world patients receiving PCI for coronary bifurcation, an extended DAPT strategy was associated with a reduction of MACE in ACS but not in CCS patients., (Copyright © 2021 Elsevier Inc.

Background: The risk of recurrent ischemia and bleeding after percutaneous coronary intervention (PCI) for acute coronary syndrome (ACS) may vary during the first year of follow-up according to clinical presentation, and medical and interventional strategies., Methods: BleeMACS and RENAMI are 2 multicenter registries enrolling patients with ACS treated with PCI and clopidogrel, prasugrel, or ticagrelor. The average daily ischemic and bleeding risks (ADIR and ADBR) in the first year after PCI were the primary end points. The difference between ADBR and ADIR was calculated to estimate the potential excess of bleeding/ischemic events in a given period or specific subgroup., Results: A total of 19,826 patients were included. Overall, in the first year after PCI, the ADBR was 0.008085%, whereas ADIR was 0.008017% (P = .886). In the first 2 weeks ADIR was higher than ADBR (P = .013), especially in patients with ST-segment elevation myocardial infarction or incomplete revascularization. ADIR continued to be, albeit non-significantly, greater than ADBR up to the third month, whereas ADBR became higher, although not significantly, afterward. Patients with incomplete revascularization had an excess in ischemic risk (P = .003), whereas non-ST-segment elevation ACS patients and those on ticagrelor had an excess of bleeding (P = .012 and P = .022, respectively)., Conclusions: In unselected ACS patients, ADIR and ADBR occurred at similar rates within 1 year after PCI. ADIR was greater than ADBR in the first 2 weeks, especially in ST-segment elevation myocardial infarction patients and those with incomplete revascularization. In the first year, ADIR was higher than ADBR in patients with incomplete revascularization, whereas ADBR was higher in non-ST-segment elevation ACS patients and in those discharged on ticagrelor., (Copyright © 2019 Elsevier Inc.

Aims: The aim of the present study was to establish the safety and efficacy profile of prasugrel and ticagrelor in real-life acute coronary syndrome (ACS) patients with renal dysfunction., Methods and Results: All consecutive patients from RENAMI (REgistry of New Antiplatelets in patients with Myocardial Infarction) and BLEEMACS (Bleeding complications in a Multicenter registry of patients discharged with diagnosis of Acute Coronary Syndrome) registries were stratified according to estimated glomerular filtration rate (eGFR) lower or greater than 60 mL/min/1.73 m2. Death and myocardial infarction (MI) were the primary efficacy endpoints. Major bleedings (MBs), defined as Bleeding Academic Research Consortium bleeding types 3 to 5, constituted the safety endpoint. A total of 19 255 patients were enrolled. Mean age was 63 ± 12; 14 892 (77.3%) were males. A total of 2490 (12.9%) patients had chronic kidney disease (CKD), defined as eGFR <60 mL/min/1.73 m2. Mean follow-up was 13 ± 5 months. Mortality was significantly higher in CKD patients (9.4% vs. 2.6%, P < 0.0001), as well as the incidence of reinfarction (5.8% vs. 2.9%, P < 0.0001) and MB (5.7% vs. 3%, P < 0.0001). At Cox multivariable analysis, potent P2Y12 inhibitors significantly reduced the mortality rate [hazard ratio (HR) 0.82, 95% confidence interval (CI) 0.54-0.96; P = 0.006] and the risk of reinfarction (HR 0.53, 95% CI 0.30-0.95; P = 0.033) in CKD patients as compared to clopidogrel. The reduction of risk of reinfarction was confirmed in patients with preserved renal function. Potent P2Y12 inhibitors did not increase the risk of MB in CKD patients (HR 1.00, 95% CI 0.59-1.68; P = 0.985)., Conclusion: In ACS patients with CKD, prasugrel and ticagrelor are associated with lower risk of death and recurrent MI without increasing the risk of MB., (Published on behalf of the European Society of Cardiology.

Introduction: The safety and efficacy of prasugrel and ticagrelor in patients with diabetes mellitus presenting with acute coronary syndrome and treated with percutaneous coronary intervention remain to be assessed., Methods: All diabetes patients admitted for acute coronary syndrome and enrolled in the REgistry of New Antiplatelets in patients with Myocardial Infarction (RENAMI) were compared before and after propensity score matching. Net adverse cardiovascular events (composite of death, stroke, myocardial infarction and BARC 3-5 bleedings) and major adverse cardiovascular events (composite of death, stroke and myocardial infarction) were the co-primary endpoints. Single components of primary endpoints were secondary endpoints., Results: Among 4424 patients enrolled in RENAMI, 462 and 862 diabetes patients treated with prasugrel and ticagrelor, respectively, were considered. After propensity score matching, 386 patients from each group were selected. At 19±5 months, major adverse cardiovascular events and net adverse cardiovascular events were similar in the prasugrel and ticagrelor groups (5.4% vs. 3.4%, P =0.16 and 6.7% vs. 4.1%, P =0.11, respectively). Ticagrelor was associated with a lower risk of death and BARC 2-5 bleeding when compared to prasugrel (2.8% vs. 0.8%, P =0.031 and 6.0% vs. 2.6%, P =0.02, respectively) and a clear but not significant trend for a reduction of BARC 3-5 bleeding (2.3% vs. 0.8%, P =0.08). There were no significant differences in myocardial infarction recurrence and stent thrombosis., Conclusion: Diabetes patients admitted for acute coronary syndrome seem to benefit equally in terms of major adverse cardiovascular events from ticagrelor or prasugrel use. Ticagrelor was associated with a significant reduction in all-cause death and bleedings, without differences in recurrent ischaemic events, which should be confirmed in dedicated randomised controlled trials.

Introduction: Ticagrelor and prasugrel are recommended as first line therapy in patients with acute coronary syndromes (ACS). However, patients with anemia are commonly treated with clopidogrel in routine clinical practice. The RENAMI registry (REgistry of New Antiplatelet therapy in patients with acute Myocardial Infarction) included ACS patients treated with prasugrel or ticagrelor at hospital discharge. The aim of this study was to analyze the prevalence of anemia and characteristics and outcomes of these patients according to anemia status., Methods: Consecutive patients with ACS from 11 centers were included. All patients underwent percutaneous coronary intervention (PCI). Anemia was defined as hemoglobin <130 g/L in men and <120 g/L in women. The incidence of ischemic and bleeding events and all-cause mortality were assessed at one year., Results: From 4424 patients included, 405 (9.2%) fulfilled criteria of anemia. Patients with anemia were significantly older, had a higher prevalence of peripheral artery disease, previous bleeding and renal disfunction and higher bleeding risk (PRECISE-DAPT score ≥ 25: 37.3% vs 18.8%, p < 0.001) The incidence of BARC 3/5 bleeding was moderately higher in patients with anemia (5.4% vs 1.5%, p = 0.001). The incidence of stent thrombosis or reinfarction was not significantly different according to anemia status. Anemia was independently associated with mortality (HR 1.73; 95% CI 1.03-2.91, p = 0.022)., Conclusions: A not negligible proportion of patients treated with ticagrelor or prasugrel met criteria for anemia. Anemia was an independent predictor of mortality. Despite their higher bleeding risk profile, patients with anemia had an acceptable rate of bleeding., (Copyright © 2018 Elsevier Ltd.

Aims: The long-term impact of beta blockers on prognosis in patients treated with contemporary therapies for coronary artery disease remains to be defined., Methods and Results: All observational studies evaluating the impact of beta blockers in patients treated with coronary revascularization and contemporary therapies and adjusted with multivariate analysis were included. All-cause death was the primary endpoint, while Major Adverse Cardiac Events (MACE) (composite endpoint of all-cause death or myocardial infarction, MI) and MI were secondary endpoints. A total of 26 studies were included, with 863 335 patients. After 3 (1-4.3) years, long-term risk of all-cause death was lower in patients on beta blockers [odds ratio, OR 0.69 (0.66-0.72)], both for Acute Coronary Syndrome (ACS) [OR 0.60 (0.56-0.65)], and stable angina patients [OR 0.84 (0.78-0.91)], independently from ejection fraction [OR 0.64 (0.42-0.98) for reduced ejection fraction and OR 0.79 (0.69-0.91) for preserved ejection fraction]. The risk of long-term MACE was lower but NS for ACS patients treated with beta blockers [OR 0.83 (0.69-1.00)], as in stable angina. Similarly, risk of MI did not differ between patients treated with beta blockers or without beta blockers [OR 0.99 (0.89-1.09), all 95% confidence intervals]. Using meta-regression analysis, the benefit of beta blockers was increased for those with longer follow-up. The number needed to treat was 52 to avoid one event of all-cause death for ACS patients and 111 for stable patients., Conclusion: Even in percutaneous coronary intervention era, beta blockers reduce mortality in patients with coronary artery disease, confirming their protective effect, which was consistent for both ACS and stable patients indifferently of preserved or reduced ejection fraction.

Background: Safety and efficacy of bioresorbable vascular scaffolds (BRS) and the role of postdilatation on outcome in acute coronary syndrome (ACS) patients compared with those of everolimus-eluting stents (EES) remain unknown. The aim of the study is to compare the safety and efficacy of BRS with EES in ACS and to investigate the role of BRS postdilatation., Methods: Consecutive ACS patients undergoing BRS implantation in 8 centers were com-pared with those with EES before and after propensity score matching. Major adverse cardiac event (MACE), myocardial infarction, and target lesion revascularization (TLR) were the primary endpoint. Sensitivity analysis was performed according to postdilatation after BRS implantation. We enrolled 303 BRS and 748 EES patients; 215 from each group were com-pared after matching, and 117 (55.2%) BRS patients were treated with postdilatation., Results: After a median follow-up of 24.0 months, MACE rates were higher in BRS patients than in EES patients (9.3% vs. 4.7%, p < 0.001), mainly driven by TLR (6.1% vs. 1.9%, p < 0.001). Stent thrombosis increased in the BRS group (2.8% vs. 0.9%, p = 0.01). How-ever, after sensitivity analysis, MACE rates in BRS patients with postdilatation were signifi-cantly lower than in those without, comparable to EES patients (6.0% vs. 12.6% vs. 4.7%, p < 0.001). The same trend was observed for TLR (3.4% vs. 8.4% vs. 1.9%, p < 0.001). Stent thrombosis rates were higher in both the BRS groups than in EES patients (2.6% vs. 3.2% vs. 0.9%, p = 0.045)., Conclusions: Postdilatation appears effective when using BRS in ACS patients. MACE rates are comparable to those of EES, although scaffold thrombosis is not negligible. Randomized prospective studies are required for further investigation.

Objective: Lichen planus has been recently associated with an increased risk of cardiovascular diseases (CVDs). The oral manifestations can be divided into white hyperkeratotic lesions (WL) and atrophic and erosive lesions (RL). The aim of this report was to compare the presence of CVDs between patients affected by WL or RL, to test the hypothesis that RL are associated with an increased incidence of CVDs. Subjects and methods: Patients were analysed through a complete collection of all the risk factors for CVDs. The primary endpoint was the occurrence of a cardiovascular event—acute coronary syndrome (ACS), any revascularization or stroke/TIA. A multivariable logistic regression model, adjusted for age at diagnosis, body mass index, smoking, alcohol consumption, diabetes, hypertension, CVDs familiarity and periodontitis, was performed. Results: A prospective cohort of 307 patients has been evaluated; 185 (60.3%) had WL and 122 RL (39.7%). Twenty‐four patients had a CVD. ACS occurred more frequently in RL (adjusted odds ratio 5.83; 95% CI: 1.16—29.39), mainly due to the higher risk of it after the histological diagnosis of Oral lichen planus OLP (odds ratio 4.23; 95% CI: 0.66—27.23). Conclusion: Patients with RL could possibly have a higher risk of developing ACS. Further analysis on larger cohort is however warranted. [ABSTRACT FROM AUTHOR]
