Balloon angioplasty in acute myocardial infarction is an established procedure. The procedure is limited by the potential for early abrupt reocclusion (18-20%) and other complications. Coronary stenting improves the initial success rate, decreases the incidence of abrupt closure, and is associated with a reduced rate of restenosis. For these reasons, coronary stenting is increasingly utilized to treat acute myocardial infarction. The purpose of this study was to compare the effect of coronary stenting with percutaneous transluminal coronary angioplasty (PTCA) in the management of acute myocardial infarction. Clinical data from a retrospective review of 228 consecutive patients admitted with acute myocardial infarction who underwent primary or rescue coronary intervention were used. There was a significantly greater incidence of in-hospital recurrent myocardial infarction in the PTCA group (10%) versus the stented group (1%). In the PTCA cohort, 10 patients required in-hospital repeat revascularization by PTCA compared with one patient in the stented group. The in-hospital death rate was significantly higher in the PTCA group (8%) compared with the stented group (1%). There was no significant difference in the incidence of postdischarge death or repeated revascularization. The results suggest that patients who undergo PTCA with stent deployment have fewer episodes of in-hospital recurrent angina, myocardial infarctions, repeat angioplasties, and fewer in-hospital deaths. PTCA with stenting was associated with a low in-hospital mortality (1%). For patients who had PTCA alone and survived to be discharged, there was no significant difference in overall mortality or the need for revascularization over the 2-year follow-up period.

Background: The prevalence of recreational drug use in myocardial infarction (MI) patients without standard modifiable cardiovascular risk factors (SMuRF) namely hypercholesterolemia, hypertension, diabetes and smoking, remains unknown.
Methods: All patients enrolled in The Addiction in Intensive Cardiac Care Units (ADDICT-ICCU) study, a French multicenter prospective observational study which systematically assessed the use of recreational drug within 2 h of admission, and presenting with MI but without known coronary artery disease were included. We compared patients with and without SMuRF.

Coronary artery disease (CAD) is a leading cause of morbidity and mortality worldwide, with platelet reactivity playing a central role in its pathogenesis. Recent research has identified microRNAs (miRNAs; miRs) as potential biomarkers for CAD, due to their ability to regulate platelet function and reactivity. This review focuses on four key miRNAs-miR-223, miR-126, miR-21, and miR-150-known to influence platelet reactivity and their implications in CAD.

Background: Rural areas have higher cardiovascular disease (CVD) incidence and age-adjusted mortality rates in the general population. However, the impact of rurality on CVD development and outcomes in patients with prostate cancer (PC) remains unclear.
Patients And Methods: This retrospective cohort study used the SEER-Medicare database to analyze males aged ≥65 years diagnosed with PC between 2009 and 2017.

Background: Machine learning (ML) models have been constructed to predict the risk of in-hospital mortality in patients with myocardial infarction (MI). Due to diverse ML models and modeling variables, along with the significant imbalance in data, the predictive accuracy of these models remains controversial.
Objective: This study aimed to review the accuracy of ML in predicting in-hospital mortality risk in MI patients and to provide evidence-based advices for the development or updating of clinical tools.
