Introduction: High-sensitivity cardiac troponin (hs-cTn) is a key biomarker for myocardial injury, yet its prognostic value in intensive cardiovascular care units (ICCU) remains poorly understood. We aimed to assess the association between peak hs-cTn levels and prognosis in ICCU patients., Methods: All patients admitted to a tertiary care center ICCU between July 2019 - July 2023 were prospectively enrolled. Patients were divided into five groups according to their peak hs-cTnI levels: A) hs-cTnI <100 ng/L; B) hs-cTnI of 100-1000 ng/L; C) hs-cTnI of 1000-10,000 ng/L; D) hs-cTnI of 10,000-100,000 ng/L and E) hs-cTnI ≥100,000 ng/L. The primary outcome was all-cause mortality at one year., Results: A total of 4149 patients (1273 females [30.7 %]) with a median age of 69 (IQR 58-79) were included. Group E was highly specific for myocardial infarction (97.4 %) and especially for ST segment elevation myocardial infarction (STEMI) (87.5 %). Patients in group E were 56 % more likely to die at 1-year in an adjusted Cox model (95 % CI 1.09-2.23, p = 0.014) as compared with group A. Subgroup analyses revealed that among STEMI patients, higher peak hs-cTnI levels were not associated with higher mortality rate (HR 1.04, 95 % CI 0.4-2.72, p = 0.9), in contrast to patients with NSTEMI (HR 7.62, 95 % CI 1.97-29.6, p = 0.003)., Conclusions: Peak hs-cTnI levels ≥100,000 ng/L were linked to higher one-year mortality, largely indicative of large myocardial infarctions. Notably, the association between elevated hs-cTnI levels and mortality differed between STEMI and NSTEMI patients, warranting further investigation., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

Background: Platelets play a key role in the natural history of aortic stenosis (AS) and after transcatheter aortic valve implantation (TAVI). An echo-based staging system stratifies patients with severe AS into 5 groups according to the associated cardiac damage phenotype. We aimed to correlate these AS stages with platelet indices in post-TAVI patients., Methods: Patients with severe AS who underwent TAVI and were admitted to intensive cardiac care unit (ICCU) were prospectively identified and divided into 5 groups according to extra-valvular cardiac damage [no extravalvular cardiac damage (Stage 0), left ventricular damage (Stage 1), left atrial or mitral valve damage (Stage 2), pulmonary vasculature or tricuspid valve damage (Stage 3), or right ventricular damage (Stage 4)]. Baseline characteristics and complete blood count including mean platelet volume (MPV) and immature platelet fraction (IPF) were collected within 2 h after the procedure and analyzed in relation to aortic stenosis staging., Results: A total of 220 patients were included. The mean age was 81 years old and 112 (50.9%) were female. Two (1%) patients were classified in stage 0; 34 (15%) in stage 1; 48 (22%) in stage 2; 49 (22%) in stage 3 and 87 (40%) in stage 4. Higher mean MPV values were correlated with higher AS staging (10.8 fL, 11 fL, 11.3 fL and 10.8 fL in stages 1, 2, 3 and 4, respectively, P = 0.02) as well as lower hemoglobin values (12 mg/dl, 11.6 mg/dl, 11 mg/dl and 11.3 mg/dl in stages 1, 2, 3 and 4, respectively P = 0.04). Mean IPF values were 5.3%, 5.58%, 5.57% and 4.83% in stage 1, 2, 3 and 4, respectively (P = 0.4). In a multivariate logistic regression model only MPV (OR = 2.6, P = 0.03) and body mass index (BMI) (OR = 1.17, P = 0.004) were correlated with higher staging (0-3) of AS., Conclusions: Although IPF and MPV levels increased in stages 0-3, there was a decrease in indices in stage 4, (probably due to bone marrow dysfunction) in this end-stage population. Higher levels of MPV and lower levels of hemoglobin were independently correlated with higher stages (0-3) of AS., (© 2024. The Author(s).)

Heart failure with reduced ejection fraction (HFrEF) represents an emerging epidemic, particularly affecting frail, older, and multimorbid patients. Current therapy for the management of HFrEF includes four different classes of disease-modifying drugs, commonly referred to as 'four pillars', which target the neurohormonal system that is overactivated in HF and contributes to its progression. These classes of drugs include β-blockers, inhibitors of the renin-angiotensin-aldosterone system, mineralocorticoid receptor antagonists, and sodium-glucose co-transporter-2 (SGLT2) inhibitors. Unfortunately, these agents cannot be administered as frequently as needed to older patients because of poor tolerability and comorbidities. In addition, although these drugs have dramatically increased the survival expectations of patients with HF, their residual risk of rehospitalization and death at 5 years remains considerable. Vericiguat, a soluble guanylate cyclase (sGC) stimulator, was reported to exert beneficial effects in patients with worsening HF, including older subjects, reducing the rate of both hospitalizations and deaths, with limited adverse effects and drug interaction. In this narrative review, we present the current state of art on vericiguat, with a particular focus on elderly and frail patients., (© 2024. The Author(s).)

Introduction: Among different coronary stents implanted in High Bleeding Risk (HBR) patients with an indication for short antiplatelet therapy, no comparisons in terms of efficacy have been provided., Methods: A Network Meta Analysis was performed including all randomized controlled trials comparing different coronary stents evaluated in HBR patients. Major Adverse Cardiovascular Events (MACEs) as defined by each included trial were the primary end point, whereas TLR (target lesion revascularization), TVR (target vessel revascularization), stent thrombosis and total and major (BARC3-5) bleedings were the secondary ones., Results: A total of four studies (ONYX ONE, LEADERS FREE, SENIOR and HBR in BIO-RESORT) including 6637 patients were analyzed with different kind of stents and dual antiplatelet therapy (DAPT) length (1 or 6 months) on 12 months follow-up. About one-third of these patients were defined HBR due to indication for oral anticoagulation. All drug eluting stents (DESs) reduced risk of MACE compared to Bare Metal Stents (BMSs) when followed by a 1-month DAPT. At SUCRA analysis, Orsiro was the device with the highest probability of performing best. Rates of TLR and TVR were significantly lower when using Resolute Onyx, Synergy and BioFreedom stents in comparison to BMS when followed by 1-month DAPT, with Synergy ranking best. Synergy also showed a significantly lower number of stent thrombosis compared to BMS (RR 0.28, 95% CI 0.06-0.93), while Orsiro and Resolute Integrity showed the highest probability of performing best., Conclusion: In HBRs patients, all DESs were superior to BMSs in terms of efficacy and safety. Among DESs, Orsiro was the one with the highest ranking in terms of MACE, mainly driven by a reduced incidence of repeated revascularization and stent thrombosis., (© 2024 Wiley Periodicals LLC.)

Aim: Sudden cardiac arrest is a significant cause of death worldwide. Good quality cardiopulmonary resuscitation increases patients' survival. Manual cardiopulmonary resuscitation is often ineffective as rescuers may experience physical and mental fatigue. Mechanical cardiopulmonary resuscitation devices are designed to address this issue, providing an automated approach for high-quality resuscitation. In the present comprehensive umbrella review we summarize current evidence on mechanical devices., Methods: We searched systematic reviews on mechanical devices in MEDLINE/PubMed. Effect estimates were obtained from original reports, including 95% confidence intervals and p values, when applicable and available, focusing on return of spontaneous circulation, survival to discharge or 30 days, survival with good neurological outcome, and resuscitation-related injuries., Results: From 21 potentially pertinent publications, we shortlisted 10 reviews, each including between 5 and 22 studies. AutoPulse, LUCAS, and LUCAS-2 were among the investigated devices. Most reviews concluded toward mechanical devices being similar or better than manual resuscitation for return of spontaneous circulation and 30-days survival. Regarding survival with good neurological function, some reviews lacked data, while the remaining ones reported similar results or worse outcomes in patients undergoing mechanical resuscitation. Focusing on resuscitation-related injuries, data were limited or conflicting with one review reporting higher rates of injuries with mechanical devices, and two others suggesting similar outcomes., Conclusions: Manual and mechanical cardiopulmonary resuscitation appear to be similar in terms of return of spontaneous circulation and short-term survival. Mechanical devices appear to be associated with higher resuscitation-related injuries, while there are conflicting data in terms of survival with good neurological outcomes. A comprehensive and large dedicated randomized trial is urgently needed., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Inc.

Background: Vascular complications (VCs) still represent one of the principal concerns of trans-femoral trans-catheter aortic valve replacement (TF-TAVR). New-generation devices can minimize such complications but the arterial access management is left to the operator's choice. This study aims to describe the rate of VCs in a contemporary cohort of patients undergoing TAVR with new-generation devices and to determine whether an ultrasound-guided (USG) vs. a fluoroscopy-guided (FG) femoral access management has an impact on their prevention., Methods: This is a prospective, observational, multicenter study. Consecutive patients undergoing TAVR with new-generation devices were analyzed from January 2022 to October 2022 in five tertiary care centers. Femoral accesses were managed according to the operator's preferences. All the patients underwent a pre-discharge peripheral ultrasound control. VCs and bleedings were the main endpoints of interest., Results: A total of 458 consecutive patients were enrolled (274 in the USG group and 184 in the FG group). VCs occurred in 6.5 % of the patients (5.2 % minor and 1.3 % major). There was no difference between the USG and the FG groups in terms of any VCs (7.3 % vs. 5.4 %; p = 0.4), or any VARC-3 bleedings (6.9 % vs 6 %, p = 0.9). At logistic regression analysis, the two guidance strategies did not result as predictors of VCs (odds Ratio 0.8, 95 % Confidence Interval 0.46-1.4; P = 0.4)., Conclusions: In a contemporary cohort of patients undergoing TAVR with new-generation devices, the occurrence of VCs is low and mostly represented by minor VCs. USG and FG modalities did not affect the rate of VCs., Competing Interests: Declaration of competing interest Giuseppe Biondi-Zoccai has consulted for Amarin, Balmed, Cardionovum, Crannmedical, Endocore Lab, Eukon, Guidotti, Innovheart, Meditrial, Microport, Opsens Medical, Terumo, and Translumina, outside the present work.

Background: Acute kidney injury (AKI) is common in patients with acute coronary syndromes (ACS) treated by percutaneous coronary intervention., Objectives: Contrast media (CM) volume minimization has been advocated for prevention of AKI. The DyeVert CM diversion system (Osprey Medical, Inc) is designed to reduce CM volume during coronary procedures., Methods: In this randomized, single-blind, investigator-driven clinical trial conducted in 4 Italian centers from February 4, 2020 to September 13, 2022, 550 participants with ACS were randomly assigned in a 1:1 ratio to the following: 1) the contrast volume reduction (CVR) group (n = 276), in which CM injection was handled by the CM diversion system; and 2) the control group (n = 274), in which a conventional manual or automatic injection syringe was used. The primary endpoint was the rate of AKI, defined as a serum creatinine (sCr) increase ≥0.3 mg/dL within 48 hours after CM exposure., Results: There were 412 of 550 (74.5%) participants with ST-segment elevation myocardial infarction (211 of 276 [76.4%] in the CVR group and 201 of 274 [73.3%] in the control group). The CM volume was lower in the CVR group (95 ± 30 mL vs 160 ± 23 mL; P < 0.001). Seven participants (1 in the CVR group and 6 in the control group) did not have postprocedural sCr values. AKI occurred in 44 of 275 (16%) participants in the CVR group and in 65 of 268 (24.3%) participants in the control group (relative risk: 0.66; 95% CI: 0.47-0.93; P = 0.018)., Conclusions: CM volume reduction obtained using the CM diversion system is effective for prevention of AKI in patients with ACS undergoing invasive procedures.

Cangrelor, the first intravenous P2Y 12 inhibitor (P2Y 12 -I), has been approved on the basis of three large RCTs from the CHAMPION program which nevertheless have been criticized for the low bleeding risk of the enrolled patients, the large quote of chronic coronary syndromes, and the use of Clopidogrel as control arm even in the setting of acute coronary syndromes (ACS). We sought to investigate, in the setting of ACS, the comparative performance of Cangrelor in terms of in-hospital ischemic and haemorrhagic outcomes compared with the current gold-standard of oral P2Y 12 -I. The study retrospectively enrolled 686 consecutive patients admitted to the Divisions of Cardiology of Policlinico of Bari and L. Bonomo Hospital of Andria for ACS and treated with percutaneous coronary intervention. The study population was divided according to the P2Y 12 -I treatment strategy in two groups: patients given an oral P2Y 12 -I and patients receiving Cangrelor in the cath lab followed by an oral P2Y 12 -I. Clinical endpoints included death, ischemic and bleeding events occurring during hospital stay. Cangrelor treated patients presented higher clinical risk profile at presentation and faced higher death rate. However, after PS matching, in-hospital mortality resulted comparable between the groups and Cangrelor use was associated with reduced in-hospital definite stent thrombosis (p = 0.03). Data from our real-world registry highlight that, in the setting of ACS, Cangrelor is prevalently used in patients with very challenging clinical presentations. The adjusted analysis provides for the first time promising data on stent thrombosis reduction associated with Cangrelor use., (© 2023. The Author(s).)

Background: The impact of myocardial revascularization on outcomes and prognosis in patients with chronic coronary syndrome (CCS) without left main (LM) disease or reduced left ventricle ejection fraction (LVEF) may be influenced by the revascularization strategy adopted., Methods: We performed a network meta-analysis including 18 randomized controlled trials comparing different revascularization strategies, including angiography-guided percutaneous coronary intervention (PCI), physiology-guided PCI and coronary artery bypass graft (CABG), in patients with CCS without LM disease or reduced LVEF., Results: Compared with medical therapy, all revascularization strategies were associated with a reduction of the primary endpoint, as defined in each trial, the extent of which was modest with angiography-guided PCI (IRR 0.86, 95% CI 0.75-0.99) and greater with physiology-guided PCI (IRR 0.60, 95% CI 0.47-0.77) and CABG (IRR 0.58, 95% CI 0.48-0.70). Moreover, angiography-guided PCI was associated with an increase of the primary endpoint compared to physiology-guided PCI (IRR 1.43, 95% CI 1.14-1.79) and CABG (IRR 1.49, 95% CI 1.27-1.74). CABG was the only strategy associated with reduced myocardial infarction (IRR 0.68, 95% CI 0.52-0.90), cardiovascular death (IRR 0.76, 95% CI 0.64-0.89), and all-cause death (IRR 0.87, 95% CI 0.77-0.99), but increased stroke (IRR 1.69, 95% CI 1.04-2.76)., Conclusions: In CCS patients without LM disease or reduced LVEF, physiology-guided PCI and CABG are associated with better outcomes than angiography-guided PCI. Compared with medical therapy, CABG is the only revascularization strategy associated with a reduction of myocardial infarction and death rates, at the cost of higher risk of stroke., Study Registration: This study is registered in PROSPERO (CRD42022313612)., Competing Interests: Declaration of Competing Interest M.G. declares that he has received consulting fees or honoraria from Terumo, outside the present work.

Aims: Little is known about the outcomes and processes of care of patients with non-ST-segment myocardial infarction (NSTEMI) who present with 'polyvascular' disease., Methods and Results: We analysed 287 279 NSTEMI patients using the Myocardial Ischaemia National Audit Project registry. Clinical characteristics and outcomes were analysed according to history of affected vascular bed-coronary artery disease (CAD), cerebrovascular disease (CeVD), and peripheral vascular disease (PVD)-with comparison to a historically disease-free control group, comprising 167 947 patients (59%). After adjusting for demographics and management, polyvascular disease was associated with increased likelihood of major adverse cardiovascular events (MACEs) [CAD odds ratio (OR): 1.06; 95% confidence interval (CI): 1.01-1.12; P = 0.02] (CeVD OR: 1.19; 95% CI: 1.12-1.27; P < 0.001) (PVD OR: 1.22; 95% CI: 1.13-1.33; P < 0.001) and in-hospital mortality (CeVD OR: 1.24; 95% CI: 1.16-1.32; P < 0.001) (PVD OR: 1.33; 95% CI: 1.21-1.46; P < 0.001). Patients without vascular disease were less frequently discharged on statins (PVD 88%, CeVD 86%, CAD 90%, and control 78%), and those with moderate [ejection fraction (EF) 30-49%] or severe left ventricular systolic dysfunction (EF < 30%) were less frequently discharged on angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs) (CAD 82%, CeVD 77%, PVD 77%, and control 74%). Patients with polyvascular disease were less likely to be discharged on dual antiplatelet therapy (DAPT) (PVD 78%, CeVD 77%, CAD 80%, and control 87%)., Conclusion: Polyvascular disease patients had a higher incidence of in-hospital mortality and MACEs. Patients with no history of vascular disease were less likely to receive statins or ACE inhibitors/ARBs, but more likely to receive DAPT., (© The Author(s) 2022.

Aims: We assessed the efficacy of the drugs developed after neurohormonal inhibition (NEUi) in patients with heart failure (HF) with reduced ejection fraction (HFrEF) and concomitant chronic kidney disease (CKD)., Methods and Results: The literature was systematically searched for phase 3 randomized controlled trials (RCTs) involving ≥90% patients with left ventricular ejection fraction <45%, of whom <30% were acutely decompensated, and with published information about the subgroup of estimated glomerular filtration rate <60 mL/min/1.73 m2. Six RCTs were included in a study-level network meta-analysis evaluating the effect of NEUi, ivabradine, angiotensin receptor-neprilysin inhibitor (ARNI), sodium-glucose cotransporter-2 inhibitors (SGLT2i), vericiguat, and omecamtiv mecarbil (OM) on a composite outcome of cardiovascular death or hospitalization for HF. In a fixed-effects model, SGLT2i [hazard ratio (HR) 0.78, 95% credible interval (CrI) 0.69-0.89], ARNI (HR 0.79, 95% CrI 0.69-0.90), and ivabradine (HR 0.82, 95% CrI 0.69-0.98) decreased the risk of the composite outcome vs. NEUi, whereas OM did not (HR 0.98, 95% CrI 0.89-1.10). A trend for improved outcome was also found for vericiguat (HR 0.90, 95% CrI 0.80-1.00). In indirect comparisons, both SLGT2i (HR 0.80, 95% CrI 0.68-0.94) and ARNI (HR 0.80, 95% CrI 0.68-0.95) reduced the risk vs. OM; furthermore, there was a trend for a greater benefit of SGLT2i vs. vericiguat (HR 0.88, 95% CrI 0.73-1.00) and ivabradine vs. OM (HR 0.84, 95% CrI 0.68-1.00). Results were comparable in a random-effects model and in sensitivity analyses. Surface under the cumulative ranking area scores were 81.8%, 80.8%, 68.9%, 44.2%, 16.6%, and 7.8% for SGLT2i, ARNI, ivabradine, vericiguat, OM, and NEUi, respectively., Conclusion: Expanding pharmacotherapy beyond NEUi improves outcomes in HFrEF with CKD., (© The Author(s) 2021.

Background: Postoperative acute kidney injury (AKI) is frequent in cardiac surgery patients. Its pathophysiology is complex and involves decreased renal perfusion. Preliminary clinical evidence in critically ill patients shows that amino acids infusion increases renal blood flow and may decrease the incidence and severity of AKI. We designed a study to evaluate the effectiveness of perioperative continuous infusion of amino acids in decreasing AKI., Methods: This is a phase III, multi-center, randomized, double-blind, placebo-controlled trial. Adults undergoing cardiac surgery with cardiopulmonary bypass (CPB) are included. Patients are randomly assigned to receive either continuous infusion of a balanced mixture of amino acids in a dose of 2 g/kg ideal body weight/day or placebo (balanced crystalloid solution) from the operating room up to start of renal replacement therapy (RRT), or ICU discharge, or 72 h after the first dose. The primary outcome is the incidence of AKI during hospital stay defined by KDIGO (Kidney Disease: Improving Global Outcomes). Secondary outcomes include the need for, and duration of, RRT, mechanical ventilation; ICU and hospital length of stay; all-cause mortality at ICU, hospital discharge, 30, 90, and 180 days after randomization; quality of life at 180 days. Data will be analyzed in 3500 patients on an intention-to-treat basis., Discussion: The trial is ongoing and currently recruiting. It will be one of the first randomized controlled studies to assess the relationship between amino acids use and kidney injury in cardiac surgery. If our hypothesis is confirmed, this practice could reduce morbidity in the studied population., Study Registration: This trial was registered on ClinicalTrials.gov with the trial identification NCT03709264 in October 2018., Competing Interests: Declaration of Competing Interest The authors declare that they have no competing interests., (Copyright © 2022 Elsevier Inc.

Background: A severe prosthesis-patient mismatch (PPM) is associated with adverse outcomes following transcatheter aortic valve replacement (TAVR) for de novo aortic stenosis or a failed surgical bioprosthesis. The impact of severe PPM in patients undergoing TAV-in-TAVR is unknown., Aim: We sought to investigate the incidence and 1-year outcomes of different grades of PPM in patients undergoing TAV-in-TAVR., Materials and Methods: The TRANSIT-PPM is an international registry, including cases of degenerated TAVR treated with a second TAVR. PPM severity, as well as in-hospital, 30-day, and 1-year outcomes were defined according to the Valve Academic Research Consortium-3 (VARC-3) criteria., Results: Among 28 centers, 155 patients were included. Severe PPM was found in 6.5% of patients, whereas moderate PPM was found in 14.2% of patients. The rate of severe PPM was higher in patients who underwent TAV-in-TAVR with a second supra-annular self-expanding (S-SE) TAVR (10%, p = 0.04). Specifically, the rate of severe PPM was significantly higher among cases of a SE TAVR implanted into a balloon-expandable (BE) device (19%, p = 0.003). At 1-year follow-up, the rate of all-cause mortality, and the rate of patients in the New York Heart Association (NYHA) class III/IV were significantly higher in the cohort of patients with severe PPM ( p = 0.016 and p = 0.0001, respectively). Almost all the patients with a severe PPM after the first TAVR had a failed < 23 mm BE transcatheter heart valve (THV): the treatment with an S-SE resolved the severe PPM in the majority of the cases., Conclusion: After TAV-in-TAVR, in a fifth of the cases, a moderate or severe PPM occurred. A severe PPM is associated with an increased 1-year all-cause mortality., Clinical Trial Registration: [https://clinicaltrials.gov], identifier [NCT04500964]., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Testa, Casenghi, Criscione, Van Mieghem, Tchétché, Asgar, De Backer, Latib, Reimers, Stefanini, Trani, Giannini, Bartorelli, Wojakowski, Dabrowski, Jagielak, Banning, Kharbanda, Moreno, Schofer, Brinkmann, van Royen, Pinto, Serra, Segev, Giordano, Brambilla, Agnifili, Rubbio, Squillace, Oreglia, Tanja, McCabe, Abizaid, Voskuil, Teles, Zoccai, Sondergaard and Bedogni.)

Little is known about how frequently do-not-resuscitate (DNR) orders are placed in patients with acute myocardial infarction (AMI), the types of patients in which they are placed, treatment strategies or clinical outcomes of such patients. Using the United States (US) National Inpatient Sample (NIS) database from 2015 to 2018, we identified 2,767,549 admissions that were admitted to US hospitals and during the hospitalization received a principle diagnosis of AMI, of which 339,270 (12.3%) patients had a DNR order (instigated both preadmission and during in-hospital stay). Patients with a DNR status were older (median age 83 vs 65, p < 0.001), more likely to be female (53.4% vs 39.3%, p < 0.001) and White (81.0% vs 73.3%, p < 0.001). Predictors of DNR status included comorbidities such as heart failure (OR: 1.47, 95% CI: 1.45 to 1.48), dementia (OR: 2.53, 95% CI: 2.50 to 2.55), and cancer. Patients with a DNR order were less likely to undergo invasive management or be discharged home (13.5% vs 52.8%), with only 1/3 receiving palliative consultation. In hospital mortality (32.7% vs 4.6%, p < 0.001) and MACCE (37.1% vs 8.8%, p < 0.001) were higher in the DNR group. Factors independently associated with in-hospital mortality among patients with a DNR order included a STEMI presentation (OR: 2.90, 95% CI: 2.84 to 2.96) and being of Black (OR: 1.29, 95% CI: 1.26 to 1.33), Hispanic (OR: 1.36, 95% CI: 1.32 to 1.41) or Asian/Pacific Islander (OR: 1.56, 95% CI:1.49-race. In conclusion, AMI patients with a DNR status were older, multimorbid, less likely to receive invasive management, with only one third of patients with DNR status referred for palliative care., (Copyright © 2021 Elsevier Inc.

Aims: Coronavirus disease 2019 (COVID-19) has caused an unprecedented change in the apparent epidemiology of acute coronary syndromes (ACS). However, the interplay between this disease, changes in pollution, climate, and aversion to activation of emergency medical services represents a challenging conundrum. We aimed at appraising the impact of COVID-19, weather, and environment features on the occurrence of ST-elevation myocardial infarction (STEMI) and non-ST-elevation myocardial infarction (NSTEMI) in a large Italian region and metropolitan area., Methods and Results: Italy was hit early on by COVID-19, such that state of emergency was declared on January 31, 2020, and national lockdown implemented on March 9, 2020, mainly because the accrual of cases in Northern Italy. In order to appraise the independent contribution on changes in STEMI and NSTEMI daily rates of COVID-19, climate and pollution, we collected data on these clinical events from tertiary care cardiovascular centers in the Lazio region and Rome metropolitan area. Multilevel Poisson modeling was used to appraise unadjusted and adjusted effect estimates for the daily incidence of STEMI and NSTEMI. The sample included 1448 STEMI and 2040 NSTEMI, with a total of 2882 PCI spanning 6 months. Significant reductions in STEMI and NSTEMI were evident already in early February 2020 (all P  < 0.05), concomitantly with COVID-19 spread and institution of national countermeasures. Changes in STEMI and NSTEMI were inversely associated with daily COVID-19 tests, cases, and/or death ( P  < 0.05). In addition, STEMI and NSTEMI incidences were associated with daily NO2, PM10, and O3 concentrations, as well as temperature ( P  < 0.05). Multi-stage and multiply adjusted models highlighted that reductions in STEMI were significantly associated with COVID-19 data ( P  < 0.001), whereas changes in NSTEMI were significantly associated with both NO2 and COVID-19 data (both P  < 0.001)., Conclusion: Reductions in STEMI and NSTEMI in the COVID-19 pandemic may depend on different concomitant epidemiologic and pathophysiologic mechanisms. In particular, recent changes in STEMI may depend on COVID-19 scare, leading to excess all-cause mortality, or effective reduced incidence, whereas reductions in NSTEMI may also be due to beneficial reductions in NO2 emissions in the lockdown phase., (Published on behalf of the European Society of Cardiology.

Aims: Strong epidemiologic evidence has highlighted the role of pollution, on top of adverse climate features, as a novel cardiovascular risk factor. However, mechanistic proof that reducing pollution may be beneficial to prevent atherothrombotic events is limited. We aimed at appraising the impact of temporary traffic bans in a large metropolitan area on the risk of acute coronary syndromes., Methods and Results: Aggregate and anonymized data from 15 tertiary cardiac care centers were obtained detailing pre-coronarivus disease 2019 (COVID-19) daily cases of ST-elevation myocardial infarction (STEMI) and non-ST-elevation myocardial infarction (NSTEMI), including those treated with percutaneous coronary intervention (PCI). Data on pollutants and climate were sought for the same days. Mixed level regression was used to compare the week before vs. after the traffic ban (Fortnight analysis), the 3 days before vs. after (Weekly analysis) and the Sunday before vs. after (Sunday analysis). A total of 8 days of temporary traffic bans were included, occurring between 2017 and 2020, totaling 802 STEMI and 1196 NSTEMI in the Fortnight analysis, 382 STEMI and 585 in the Weekly analysis, and 148 STEMI and 210 NSTEMI in the Sunday analysis. Fortnight and Sunday analysis did not disclose a significant impact of traffic ban on STEMI or NSTEMI (all P  > 0.05). Conversely, Weekly analysis showed non-significant changes for STEMI but a significant decrease in daily NSTEMI when comparing the 3 days before the traffic ban with the ban day ( P  = 0.043), as well as the 3 days before vs. the 3 days after the ban ( P  = 0.025). No statistically significant effect of traffic ban was found at Fortnight, Weekly or Sunday analyses for daily mean concentrations of benzene, carbon monoxide, nitric oxide, nitrogen dioxide, ozone, sulfur dioxide, particulate matter (PM) <2.5 µm or PM < 10 µm (all P  > 0.05). However, minimum daily concentrations showed a significant reduction of ozone during the ban in comparison to the week preceding it ( P  = 0.034), nitric oxide during the ban in comparison to the 3 days preceding it ( P  = 0.046), and an increase in benzene during the ban in comparison to the Sunday before ( P  = 0.039)., Conclusion: Temporary traffic bans may favorably reduce coronary atherothrombotic events, and in particular NSTEMI, even if not globally and immediately impacting on environmental pollution. Further controlled studies are required to confirm and expand this hypothesis-generating results., (Published on behalf of the European Society of Cardiology. All rights reserved. © The Author 2020.

Novel Oral Anticoagulants (NOACs) have been considered for treating cancer-related venous thromboembolism (VTE), but safety issues have been raised. We performed a systematic review and pairwise meta-analysis of the efficacy and safety of NOACs versus low molecular weight heparin (LMWH) in this setting. Four randomized controlled trials were included, providing data on 2894 patients. Compared to LMWH, NOACs were associated with a significantly lower risk of VTE recurrence and were not associated with an increased risk of major bleedings (MB). NOACs were non inferior to LMWH for a composite outcome of VTE recurrence and MB, pulmonary embolism recurrence and all-cause mortality; however, NOACs were associated with an increased risk of clinically relevant nonmajor bleedings (CRNMB) and gastrointestinal MB. In conclusion, in patients with cancer-related VTE, NOACs are effective and safe in reducing VTE recurrence compared to LMWH. An increased risk of CNRMB and GI MB should nonetheless be considered., (Copyright © 2020 Elsevier B.V. All rights reserved.)

Objectives: Reports ranged from mixed to marginal tubing wear and spallation effects as a complication of roller pumps in cardiopulmonary bypass (CPB). Because the rollers constantly compress part of the tubing, we sought to determine whether circuit materials behave differently under a 3-h simulation of CPB., Methods: Two different tubing materials (silicone and Tygon) were tested with a customized experimental circuit, designed to allow in vitro simulation of CPB with priming volumes, pressures, revolutions per minute and temperatures equivalent to the clinical scenario. Samples were analysed with optical and field-emission scanning electron microscopy. We collected 200-ml fluid samples at 4 different times: before starting the CPB (T0), when the predicted revolutions per minute corresponded to about 2 min of CPB (T1), at 90 min (T2) and at 180 min (T3). At the end of CPB, we harvested 2 samples of tubing. Lastly, optical investigations and field-emission scanning electron microscopy observations were used for qualitative and quantitative analysis of circulating fragments., Results: T2 and T3 fluid samples showed more particles than T1 samples. Significant differences in terms of particle numbers were detected: silicone tubing released more fragments per millilitre than Tygon tubing, with both materials releasing particles from 5 to 500 µm. Silicone tubing was associated with a time-dependent increase in small particles released (P = 0.04), whereas this did not apply to large particles or to Tygon tubing. Yet, bootstrap estimates suggested that silicone tubing was associated with the release of more small particles whereas Tygon tubing released more large particles (both P < 0.01). Unlike silicone, Tygon samples taken from the portion of the circuit not subjected to the action of the roller pump did not show any erosion on their surfaces. Samples of both materials taken from the portion subjected to the compression of the roller pump showed signs of significant deterioration., Conclusions: Silicone showed a worse spallation performance than Tygon, thus appearing less safe for more complex surgery of prolonged duration or for patients with a prior cerebral ischaemic event. Additional risk and cost-effectiveness comparisons to determine the potential benefits of one type of tubing material over the other are warranted to further expand our findings., (© The Author(s) 2019.

Purpose of Review: Cardiac regenerative medicine is a field bridging together biotechnology and surgical science. In this review, we present the explored surgical roads to cell delivery and the known effects of each delivery method on cell therapy efficiency. We also list the more recent clinical trials, exploring the safety and efficacy of delivery routes used for cardiac cell therapy approaches., Recent Findings: There is no consensus in defining which way is the most suitable for the delivery of the different therapeutic cell types to the damaged heart tissue. In addition, it emerged that the "delivery issue" has not been systematically addressed in each clinical trial and for each and every cell type capable of cardiac repair. Cardiac damage occurring after an ischemic insult triggers a cascade of cellular events, eventually leading to heart failure through fibrosis and maladaptive remodelling. None of the pharmacological or medical interventions approved so far can rescue or reverse this phenomenon, and cardiovascular diseases are still the leading cause of death in the western world. Therefore, for nearly 20 years, regenerative medicine approaches have focused on cell therapy as a promising road to pursue, with numerous preclinical and clinical testing of cell-based therapies being studied and developed. Nonetheless, consistent clinical results are still missing to reach consensus on the most effective strategy for ischemic cardiomyopathy, based on patient selection, diagnosis and stage of the disease, therapeutic cell type, and delivery route.

Atrial natriuretic peptide (ANP) is a cardiac hormone belonging to the family of natriuretic peptides (NPs). ANP exerts diuretic, natriuretic, and vasodilatory effects that contribute to maintain water-salt balance and regulate blood pressure. Besides these systemic properties, ANP displays important pleiotropic effects in the heart and in the vascular system that are independent of blood pressure regulation. These functions occur through autocrine and paracrine mechanisms. Previous works examining the cardiac phenotype of loss-of-function mouse models of ANP signaling showed that both mice with gene deletion of ANP or its receptor natriuretic peptide receptor A (NPR-A) developed cardiac hypertrophy and dysfunction in response to pressure overload and chronic ischemic remodeling. Conversely, ANP administration has been shown to improve cardiac function in response to remodeling and reduces ischemia-reperfusion (I/R) injury. ANP also acts as a pro-angiogenetic, anti-inflammatory, and anti-atherosclerotic factor in the vascular system. Pleiotropic effects regarding brain natriuretic peptide (BNP) and C-type natriuretic peptide (CNP) were also reported. In this review, we discuss the current evidence underlying the pleiotropic effects of NPs, underlying their importance in cardiovascular homeostasis., Competing Interests: The authors declare no conflict of interest.

Background: Treatment of patients with ULMCA (unprotected left main coronary artery disease) with percutaneous coronary intervention (PCI) has been compared with coronary artery bypass graft (CABG), without conclusive results., Methods: All randomized controlled trials (RCTs) and observational studies with multivariate analysis comparing PCI and CABG for ULMCA were included. Major cardiovascular events (MACEs, composite of all-cause death, MI, definite or probable ST, target vessel revascularization and stroke) were the primary end points, whereas its single components were the secondary ones, along with stent thrombosis, graft occlusion and in-hospital death and stroke. Subgroup analyses were performed according to Syntax score., Results: Six RCTs (4717 patients) and 20 observational studies with multivariate adjustment (14 597 patients) were included. After 5 (3-5.5) years, MACE rate was higher for PCI [odds ratio (OR) 1.10, 95% confidence interval (CI) 1.07-1.14], without difference in death, whereas more relevant risk of MI was because of observational studies. Coronary stenting increased risk of revascularization (OR 1.52; 95% CI 1.34-1.72). At meta-regression, performance of PCI was improved by use of intra-coronary imaging and worsened by first generation stents, whereas two arterial grafts increased benefit of CABG. For patients with Syntax score less than 22, MACE rates did not differ, whereas for higher values, CABG reduced MACE because of lower risk of revascularization. Incidence of graft occlusion was 3.24% (2.25-4.23), whereas 2.13% (1.28-2.98: all CI 95%) of patients experienced stent thrombosis., Conclusion: Surgical revascularization reduces risk of revascularization for ULMCA patients, especially for those with Syntax score greater than 22, with a higher risk of in-hospital death. Intra-coronary imaging and use of arterial grafts improved performance of revascularization strategies.

An unexpectedly high incidence of thrombosis in patients that received the polylactic acid bioresorbable vascular scaffold (BVS) suggests a delayed/incomplete endothelial repair with this stent. The anti-platelet agent tirofiban stimulates endothelial cell migration and proliferation, mediated by VEGF production. We investigated the tirofiban effect on the migration and adhesion of endothelial cells to BVS, in vitro. We performed human umbilical endothelial cell (HUVEC) cultures in the presence of BVS. Tirofiban, similarly to VEGF, increased the ability of HUVEC to grow on the vascular scaffold, compared to unstimulated or abciximab-treated cells. Tirofiban increased HUVEC expression of β1 and β3 integrins along with collagen and fibronectin. A role for β1 integrin in the "pro-adhesive and -migratory" signals elicited by tirofiban was suggested by use of an anti-β1-blocking antibody that prevented poly-levo-lactic acid vascular scaffold colonization. Our study suggests that tirofiban may improve the outcomes of patients receiving BVS by accelerating stent endothelization.

Background: Epidemiological studies have shown a higher risk of cardiovascular mortality associated with early menopause, but the relation between menopausal age and extent of coronary artery disease after menopause is unknown. We assessed the relation between menopausal age and extent of coronary disease in postmenopausal women with an acute coronary syndrome., Methods: A prospective study was conducted in patients ≥55 years old undergoing coronary angiography for an acute coronary syndrome. Enrollment was stratified by sex (women/men ratio 2:1) and age (55-64, 65-74, 75-85, and >85 years). Women were administered menopause questionnaires during admission. An independent core lab quantified coronary artery disease extent using the Gensini Score, which classifies both significant (>50%) and nonsignificant lesions. Linear correlation was used to appraise the association between the Gensini score and menopausal age., Results: We enrolled 675 patients, 249 men and 426 women (mean age 74 years). The mean Gensini score was 60 ± 36 in men vs 50 ± 32 in women (P <.001), being higher among men at any age. The median menopausal age of women was 50 years. Risk factors and age at first acute coronary syndrome were identical among women below and above the median menopausal age. The Gensini score in women showed a weak association with age (R = 0.127; P = .0129), but not with menopausal age (R = 0.063; P = .228). At multivariable analysis, ejection fraction, female sex, and ST elevation myocardial infarction were independent predictors of the Gensini score in the overall population., Conclusions: Menopausal age was not associated with the extent of coronary artery disease. Age at first acute coronary syndrome presentation, risk factors, and prior cardiovascular events were not affected by menopausal age.

Background: Cardiac rehabilitation (CR) is an evidence-based intervention to increase survival and quality of life. Yet studies consistently show that elderly patients are less frequently referred to CR, show less uptake and more often drop out of CR programmes., Design: The European study on effectiveness and sustainability of current cardiac rehabilitation programmes in the elderly (EU-CaRE) project consists of an observational study and an open prospective, investigator-initiated multicentre randomised controlled trial (RCT) involving mobile telemonitoring guided CR (mCR)., Objective: The aim of EU-CaRE is to map the efficiency of current CR of the elderly in Europe, and to investigate whether mCR is an effective alternative in terms of efficacy, adherence and sustainability., Methods and Results: The EU-CaRE study includes patients aged 65 years or older with ischaemic heart disease or who have undergone heart valve surgery. A total of 1760 patients participating in existing CR programmes in eight regions of Europe will be included. Of patients declining regular CR, 238 will be included in the RCT and randomised in two study arms. The experimental group (mCR) will receive a personalised home-based programme while the control group will receive no advice or coaching throughout the study period. Outcomes will be assessed after the end of CR and at 12 months follow-up. The primary outcome is VO 2peak and secondary outcomes include variables describing CR uptake, adherence, efficacy and sustainability., Conclusion: The study will provide important information to improve CR in the elderly. The EU-CaRE RCT is the first European multicentre study of mCR as an alternative for elderly patients not attending usual CR., (© The European Society of Cardiology 2016.)

The purpose of the study was to evaluate the optimal duration of dual antiplatelet therapy (DAPT) after percutaneous coronary intervention, especially in the era of second-generation drug-eluting stents (DES). The work was conducted from November 2014 to April 2015. All randomized controlled trials comparing short (<12 months) versus long (≥12 months) DAPT in patients treated with second-generation DES were analyzed. Sensitivity analyses were performed for length of DAPT and type of DES. All-cause death was the primary end point, whereas cardiovascular death, myocardial infarction (MI), stent thrombosis (ST), and major bleeding were secondary end points. Results were pooled and compared with random-effect models and meta-regression analysis. Eight randomized controlled trials with 18,810 randomized patients were included. The studies compared 3 versus 12 months of DAPT (2 trials), 6 versus 12 months (3 trials), 6 versus 24 months (1 trial), 12 versus 24 months (1 trial), and 12 versus 30 months (1 trial). Comparing short versus long DAPT, there were no significant differences in all-cause death (odds ratio [OR] 0.87; 95% confidence interval [CI] 0.66 to 1.44), cardiovascular death (OR 0.95; 95% CI 0.65 to 1.37), and ST (OR 1.20; 95% CI 0.79 to 1.83), and no differences were present when considering everolimus-eluting and fast-release zotarolimus-eluting stents separately. Shorter DAPT was inferior to longer DAPT in preventing MI (OR 1.35; 95% CI 1.03 to 1.77). Conversely, major bleeding was reduced by shorter DAPT (OR 0.60; 95% CI 0.42 to 0.96). Baseline features did not influence these results in meta-regression analysis. In conclusion, DAPT for ≤6 months is reasonable for patients treated with everolimus-eluting and fast-release zotarolimus-eluting stents, with the benefit of less major bleeding at the cost of increased MI, with similar survival and ST rates. An individualized patient approach to DAPT duration should take into account the competing risks of bleeding and ischemic complications after present-generation DES., (Copyright © 2016 Elsevier Inc.

Background: The use of inhibitors of glycoprotein IIb/IIIa (GPIIb/IIIa) has provided dramatic results in terms of the prevention of acute stent thrombosis and a reduction in major adverse coronary events in patients subjected to percutaneous coronary intervention. GPIIb/IIIa or αIIbβ3 is a member of the β3 subfamily of integrins, which also includes αVβ3. GPIIb/IIIa functions as a receptor for fibrinogen and several adhesion proteins sharing an arginine-glycine-aspartic acid (RGD) sequence. GPIIb/IIIa antagonists, through blockade of the receptor, prevent platelet aggregation. Among the three GPIIb/IIIa antagonists used in therapy, abciximab is an anti-β3 monoclonal antibody, while tirofiban and eptifibatide mimic the binding sequence of the fibrinogen ligand. Although antiplatelet aggregation represents the central function of GPIIb/IIIa inhibitors, further actions have been documented for these compounds., Objective: The aim of the present article is to review the structures and functions of GPIIb/IIIa antagonists and to highlight the clinical outcomes and results of randomized trials with these compounds. Hypotheses on the unexplored potential of GPIIb/IIIa antagonists will be put forward., Conclusion: GPIIb/IIIa inhibitors were developed to prevent platelet aggregation, however, these compounds can exert further biological functions, both platelet- and non-platelet-related. Large-scale studies comparing the efficacy and safety of GPIIb/IIIa antagonists are lacking. More insights into the functions of these compounds may lead to generation of novel small molecules able to antagonize platelet aggregation while promoting vascular repair.

Background: The most suitable approach for patients with aspirin hypersensitivity undergoing percutaneous coronary intervention remains to be assessed., Methods and Results: Pubmed, Google Scholar, and Cochrane were systematically searched for papers describing protocols about aspirin hypersensitivity in the percutaneous coronary intervention setting. Discharge from hospital with aspirin was the primary end point, whereas rates of adverse reactions being a secondary outcome. An online international survey was performed to critically analyze rates of aspirin hypersensitivity and its medical and interventional management. Eleven studies with 283 patients were included. An endovenous desensitization protocol was performed on one of them, with high efficacy rate (98%) and a low adverse reaction rate when compared with oral administration. No significant differences were reported among the oral protocols in terms of efficacy (less versus more fractionated [95.8% {95.4%-96.2%} versus 95.9% {95.2-96.5%}]), whereas higher incidence of rash and angioedema were reported for protocols with <6 doses escalation (2.6% [1.1%-4.1%] versus 2.6% [1.9%-3.2%]). In the survey, we collected answer from 86 physician of the 100 interviewed. Fifty-six percent of them managed aspirin hypersensitivity changing the therapeutic regimen (eg, clopidogrel monotherapy and indobufen). Despite the previous safety data, desensitization protocols were adopted by only 42% of surveyed cardiologist., Conclusions: Available protocols for aspirin hypersensitivity are effective and safe, representing a feasible approach for patients needing dual antiplatelet therapy., (© 2016 American Heart Association, Inc.)

Background: Cardiovascular disease represents an important cause of morbidity and mortality in patients with a diagnosis of systemic lupus erythematosus (SLE), due to a complex interplay between traditional risk factors and disregulation of autoimmunity but uncertainty is still present about the most important predictors of cardiovascular events., Objectives: The aim of our work was to perform a collaborative systematic review on the main predictors of cardiovascular events in SLE patients., Methods: PubMed and Cochrane were systematically searched for eligible studies on SLE and cardiovascular events between January 2008 and December 2012. Study features, patient characteristics and incidence of stent thrombosis were abstracted and pooled, when appropriate, with random-effect methods (point estimate - 95% confidence intervals) and consistency of predictors was formally appraised., Results: A total of 17,187 patients was included; of those, 93.1% were female and the median age was 39 years. After a median follow-up period of 8 years, cardiovascular events presented in 25.4%, including acute myocardial infarction (4.1%) and stroke (7.3%). The most important predictors may be divided into traditional risk factors, such as male gender (OR 6.2, CI 95% 1.49-25), hyperlipidaemia (OR 3.9, CI 95% 1.57-9.71), familiar history of cardiac disease (OR 3.6, CI 95% 1.15-11.32) and hypertension (OR 3.5, CI 95% 1.65-7.54), and SLE-related features, such as the presence of auto-antibodies (OR 5.8 and 5.0, CI 95% 3.28-7.78) and neurological disorders (OR 5.2, CI 95% 2.0-13.9). A low correlation was shown for the importance of organ damage and SLE activity (respectively OR 1.4, CI 95% 1.09-4.44 and OR 1.2, CI 95% 1.2-1.2), as well as for age at diagnosis (OR 1.1, CI 95% 1.07-1.17)., Conclusions: Cardiovascular events in SLE patients are caused by a multifactorial mechanism, including both traditional and disease-specific risk factors. A global valuation with an individual risk stratification based on both these features is important to correctly manage these patients in order to reduce negative outcomes., (© The European Society of Cardiology 2014.)

Aims: Thirty-day readmission rate after percutaneous coronary intervention (PCI) is used as an index of quality of care, but the complete recovery from any myocardial damage needs 8 weeks. We evaluated the readmission rate 60 days after PCI, defined its predictors, and investigated its relationship with long-term prognosis., Methods and Results: All consecutive patients undergoing PCI in a large volume hospital were enrolled, and their outcomes were explored using an institutional database. The primary outcome was unplanned 60-day readmission. A composite of major adverse cardiovascular events (MACEs) including all-cause death, myocardial infarction, and repeated revascularization were the secondary endpoints. Among the 1193 enrolled patients, 71 (6.0%) underwent unplanned 60-day readmission for unstable angina (35.3%), chest pain (21.1%), heart failure (14.1%), and acute myocardial infarction (11.3%); 40.8% patients underwent repeated PCI. Readmitted patients carried more frequently left main disease (16.9 vs. 8.3%, P = 0.001), proximal left descending artery disease (31.0 vs. 27.4%, P = 0.03), and bifurcation disease (26.8 vs. 20.5%, P = 0.03). The only predictor of readmission was left main disease. After a mean follow-up of 743 ± 334 days, patients with 60-day readmission experienced higher rates of all-cause death (8.5 vs. 3.8%, P = 0.05). General baseline conditions and multivessel disease, but not 60-day readmissions, were predictors of MACE and death at follow-up., Conclusion: Unplanned 60-day readmissions after PCI are mainly related to the extent of coronary artery disease, being associated with left main, proximal left descending artery, and bifurcation disease. Readmissions are associated with higher long-term all-cause mortality.

Introduction: Asymptomatic patients with human immunodeficiency virus (HIV) infection are at increased risk of vascular disease. Whether asymptomatic HIV patients have increased prevalence or structural differences in coronary artery plaques is not clear., Methods: Pubmed, Cochrane and Google Scholar were searched for articles evaluating asymptomatic HIV patients evaluated with coronary computed tomography. The prevalence of coronary stenosis (defined as >30% and >50%), of calcified coronary plaques (CCP) viewed as more 'stable' plaques, and of non-calcified coronary plaques (NCP) viewed as more 'vulnerable' plaques were the end points of interest., Results: 9 studies with 1229 HIV patients and 1029 controls were included. No significant differences were detected about baseline cardiovascular risk profile. The prevalence of significant coronary stenosis>30% or >50% did not differ between HIV+ and HIV- patients (42% [37-44] and 46% [35-52] with an Odds Ratio [OR] of 1.38 [0.86-2.20] for >30% stenosis) and (15% [9-21] and 14% [7-22] with an OR of 1.11 [0.81-1.52]), respectively. The prevalence of calcified coronary plaques (CCP) (31% [24-32] and 21% [14-30] with an OR of 1.17 [0.63-2.16]) also did not differ among HIV+ and HIV- patients. On the contrary rates of NCP were >3-fold higher in HIV-positive patients [58% (48-60) and 17% (14-27) with an OR of 3.26 (1-30-8.18)], with an inverse relationship with CD4 cell count at meta-regression (Beta -0.20 [-0.35-0.18], p 0.04)., Conclusion: Asymptomatic HIV patients present a similar burden of coronary stenosis and calcified coronary artery plaques but significantly higher rates of non-calcific coronary plaques at computed tomography. The association between HIV infection, reduced CD4 cell counts and higher prevalence on non-calcific coronary artery plaques may shed light into the pathogenesis in HIV-associated coronary artery disease, stressing the importance of primary prevention in this population., (Copyright © 2015 Elsevier Ireland Ltd.

Coronary artery disease represents the leading cause of death for HIV patients treated with highly active antiretroviral treatment. Besides this, an extensive amount of data related to the risk of overt heart failure and consequently of atrial fibrillation and sudden cardiac death (SCD) in this population has been reported. It seems that persistent deregulation of immunity in HIV-infected patients is a common pathway related to both of these adverse clinical outcomes. Despite the fact that atrial fibrillation and heart failure are relatively common in HIV, few data are reported about screening, diagnosis, and potential treatment of these conditions.

Introduction: Thirty-day readmission rates after percutaneous coronary intervention (PCI) have been related to adverse prognosis, and represent one of the most investigated indicators of quality of care. These data, however, derive from non-European centers evaluating all-cause readmissions, without stratification for diagnosis., Methods: All consecutive patients undergoing PCI at our center from January 2009 to December 2011 were enrolled. Thirty-day readmissions related to postinfarction angina, myocardial infarction, unstable angina or heart failure were defined as acute coronary syndrome (ACS) or heart failure rehospitalizations. Major cardiac adverse event (MACE) was the primary outcome, and its single components (death, myocardial infarction and repeated revascularization) the secondary ones., Results: A total of 1192 patients were included; among them, 53 (4.7%) were readmitted within 30 days, and 25 (2.1%) were classified as ACS/heart failure related. During hospitalization, patients with ACS/heart failure readmissions were more likely to suffer a periprocedural myocardial infarction (22 vs. 4%; P = 0.012), and to undergo PCI at 30 days (52 vs. 0.5%; P < 0.001). Logistic regression analysis indicated that periprocedural myocardial infarction represented the only independent predictor of an ACS/heart failure readmission [odds ratio (OR) 4.5; 1.1-16.8; P = 0.047]. After a median follow-up of 787 days (434-1027; first and third quartiles), patients with a 30-day ACS/heart failure readmission experienced higher rates of MACE, all-cause death and myocardial infarction (64 vs. 21%, P < 0.001; 28 vs. 6%, P = 0.017; and 20 vs. 2.7%, P < 0.001, respectively). Cox multivariate analysis indicated that ACS/heart failure 30-day readmissions were independently related to an increased risk of all-cause death (OR 3.3; 1.1-8.8; P = 0.02), differently from 30-day non-ACS/heart failure readmissions (OR 3.1; 0.7-12.9; P = 0.12)., Conclusion: Thirty-day readmissions after PCI in an Italian center are infrequent, and only those patients with ACS/heart failure show a detrimental impact on prognosis who have periprocedural myocardial infarction as the only independent predictor.

Aims: Contrast-induced nephropathy (CIN) and periprocedural myocardial infarction (PMI) represent frequent complications of percutaneous coronary intervention (PCI) and negatively impact subsequent length of hospitalization, costs of adjunctive diagnostic-therapeutic measures and mid-term cardiovascular events. The aim of the EURO-CRIPS trial is to test whether remote ischemic preconditioning (RIPC) may reduce the incidence of these complications and improve mid-term outcome., Methods: This will be a double-blind, randomized, placebo-controlled multicentre study. Patients will be allocated 1 : 1 to RIPC or standard therapy if they were younger than 85 years old, with a renal clearance in the interval 30-60 ml/min/1.73 m and candidate to PCI for all clinical indications except for primary PCI in ST segment elevation myocardial infarction (STEMI), unstable haemodynamic presentations or ongoing severe arrhythmias. Incidence of CIN will be the primary end point and the amount of periprocedural cardiac enzyme leakage will be the secondary end point. In addition, we will evaluate whether the preconditioned patients will have a reduction of MACCE at 6 months (major adverse cardiac and cerebrovascular event)., Conclusion: The EURO-CRIPS Study will be the first large-scale, multicentre clinical trial to test the role of RIPC in current clinical practice. The results of this randomized trial will provide important insights to optimize management strategy of patients undergoing PCI and to improve their outcome.
