Article Synopsis
  • The study evaluated the effectiveness and safety of clopidogrel versus aspirin as a single treatment after dual antiplatelet therapy in patients with acute coronary syndrome (ACS) who had received a drug-eluting stent.
  • After reviewing 6242 abstracts, three studies (one RCT and two observational studies) involving 7081 patients were analyzed, revealing that clopidogrel reduced the risk of major adverse cardiovascular events (MACE) by 28% compared to aspirin.
  • The findings suggest that clopidogrel may be a better option for reducing MACE without significantly increasing the risk of bleeding, but more large-scale randomized trials are needed for conclusive evidence.

Background: Patients who sustain an acute myocardial infarction (AMI), including ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI), remain at high risk for heart failure (HF), coronary events, and death. Angiotensin-converting enzyme inhibitors have been shown to significantly decrease the risk for cardiovascular events in both STEMI and NSTEMI patients.

Objectives: The objectives were to determine whether angiotensin-receptor blockade and neprilysin inhibition with sacubitril/valsartan, compared with ramipril, has impact on reducing cardiovascular events according to the type of AMI.

Lung transplantation can greatly improve quality of life and extend survival in those with end-stage lung disease. In order to derive the maximal benefit from such a procedure, patients must be carefully selected and be otherwise healthy enough to survive a high-risk surgery and sometimes prolonged immunosuppressive therapy following surgery. Patients therefore must be critically assessed prior to being listed for transplantation with close attention paid towards assessment of cardiovascular health and operative risk.

Antiplatelet therapy is the cornerstone of antithrombotic prevention in patients with established atherosclerosis, since it has been proven to reduce coronary, cerebrovascular, and peripheral thrombotic events. However, the protective effect of antiplatelet agents is counterbalanced by an increase of bleeding events that impacts on patients' mortality and morbidity. Over the last years, great efforts have been made toward personalized antithrombotic strategies according to the individual bleeding and ischemic risk profile, aiming to maximizing the net clinical benefit.

Article Synopsis
  • A study examined the role of high-sensitivity C-reactive protein (hs-CRP) levels in predicting health outcomes for patients with chronic kidney disease (CKD) who underwent percutaneous coronary intervention (PCI) from 2012 to 2019.
  • Among 12,410 patients, 24.4% had CKD, with hs-CRP levels elevated in 31.8% of CKD patients and 25.8% of those without CKD.
  • While elevated hs-CRP was linked to higher all-cause mortality in both groups, it did not significantly increase the risk of major adverse cardiac events (MACE) at 1 year after PCI.

Background: The TWILIGHT trial (NCT02270242) demonstrated that in selected high-risk patients undergoing percutaneous coronary intervention (PCI) ticagrelor monotherapy significantly reduced bleeding complications without ischemic harm as compared to ticagrelor plus aspirin after 3-month of dual antiplatelet therapy. The aim of this analysis was to assess the applicability of the findings TWILIGHT trial to a real-world population.

Methods: Patients undergoing PCI at a tertiary center between 2012 and 2019 and not meeting any TWILIGHT exclusion criterion (oral anticoagulation treatment, ST-segment elevation myocardial infarction [MI], cardiogenic shock, dialysis, prior stroke, or thrombocytopenia) were included.

A universal definition to identify patients at higher risk of complications after percutaneous coronary intervention (PCI) is lacking. We aimed to validate a recently developed score to identify patients at increased risk of all-cause death after PCI. All consecutive patients from a large PCI registry not presenting with ST-elevation myocardial infarction or cardiogenic shock were included.

Purpose Of Review: Despite mandates from funding agencies and professional societies to broaden inclusivity in medical research, women remain underrepresented in cardiovascular clinical trials. This lack of representation limits the generalizability of the findings and results in uncertainty about the safety and efficacy of many cardiovascular therapies in female patients.

Recent Findings: Several barriers impact women's participation in clinical trials, including enrollment criteria, common misconceptions, access to tertiary care, and women representation in clinical trial leadership.

Transcatheter aortic valve replacement (TAVR) has revolutionized the treatment of aortic stenosis, providing a viable alternative to surgical aortic valve replacement (SAVR) for patients deemed to be at prohibitive surgical risk, but also for selected patients at intermediate or low surgical risk. Nonetheless, there still exist uncertainties regarding the optimal management of patients undergoing TAVR. The selection of the optimal bioprosthetic valve for each patient represents one of the most challenging dilemmas for clinicians, given the large number of currently available devices.

Gender-based differences in outcomes after successful transcatheter aortic valve implantation (TAVI) in patients without an indication for oral anticoagulation have not been well studied. We aim to evaluate gender-based differences in clinical outcomes after TAVI. In the present analysis of the GALILEO (Global study comparing a rivaroxaban-based antithrombotic strategy to an antiplatelet-based strategy after transcatheter aortic valve replacement to optimize clinical outcomes) trial, patients with symptomatic severe aortic stenosis and who underwent successful TAVI were stratified by gender.
