Early Zalunfiban Injection Effective for Major Heart Attack:

In patients with ST-segment elevation myocardial infarction (STEMI), early subcutaneous administration of zalunfiban significantly improved coronary artery patency and reduced the risk of adverse 30-day clinical outcomes without increasing severe bleeding. In an international, double-blind, placebo-controlled trial of 2,467 patients randomly assigned to receive zalunfiban (0.11 mg/kg or 0.13 mg/kg) […]


Stem Cells Infusion Reduced HF Risk in AMI

Intracoronary infusion of Wharton’s jelly–derived mesenchymal stem cells after acute myocardial infarction (AMI) significantly reduced the risk of developing heart failure (HF) and related adverse cardiovascular events, suggesting its potential as a valuable adjunctive therapy. In a Iranian phase 3 randomized clinical trial involving 420 patients with a first ST-segment […]


Sex Differences in Heart Attacks in Younger Patients

In a US community-based study of patients aged ≤65 years between 2003 and 2018, researchers identified 1,474 index myocardial infarction (MI) events and classified them into six pathophysiologic mechanisms: atherothrombosis, spontaneous coronary artery dissection (SCAD), embolism, vasospasm, MI with nonobstructed coronary arteries of uncertain cause (MINOCA-U), and supply/demand mismatch secondary […]


Cold Weather Linked to Higher MI Risk

A Chinese nationwide case-crossover study revealed that lower temperatures were associated with higher risks of myocardial infarction (MI), and that the risk was more pronounced in MI with non-obstructive coronary arteries (MINOCA) than that of MI with obstructive coronary artery disease (MI-CAD). The study included 83 784 MINOCA patients and […]


No Benefit to Stop Beta-Blockers After MI

A French multicenter, open label, randomized, noninferiority trial suggested that interruption of long-term beta-blocker treatment was not found to be noninferior to a strategy of beta-blocker continuation in patients with a history of myocardial infarction (MI). A total of 3698 MI patients (mean age 63.5 years, 17.2% women) were randomized […]


Subclinical Coronary Atherosclerosis Linked to Higher MI Risk

A prospective Danish cohort study revealed that subclinical obstructive coronary atherosclerosis is associated with a more than 8-fold elevated risk for myocardial infarction (MI). The study included 9533 asymptomatic persons aged 40 years or older without known ischemic heart disease. Coronary atherosclerosis was assessed with coronary computed tomography angiography and […]


Silent MI Deadly

A population-based, prospective cohort study in Iceland revealed that the long-term mortality risk of unrecognized myocardial infarction (UMI) can be as high as clinically recognized myocardial infarction (RMI). 935 participants (aged 67-93 years, 48.3% men) were characterized with cardiac magnetic resonance (CMR) from January 2004 to January 2007 and followed […]
