Acute Coronary Syndromes

Acute coronary syndrome (ACS) is most commonly caused by a heart attack (myocardial infarction) where blood flow to the heart is suddenly blocked. This is usually caused by a blood clot from a ruptured coronary artery atherosclerotic plaque. Other causes include spontaneous coronary artery dissection (SCAD), which most commonly occurs in women. ACS is usually treated in a cath lab with angioplasty and the placement of a stent to prop the vessel open.

Insomnia linked to greater odds of CVD, stroke

A genetic predisposition for insomnia was linked to greater odds of heart disease and stroke—but not atrial fibrillation—in a study of more than a million people with or without CVD.

Machine learning predicts MI risk better than contemporary tools

A machine learning algorithm dubbed “MI3” can reportedly predict a person’s risk of heart attack with more nuance than existing algorithms, prompting its developers to claim it as “one of the first effective demonstrations” of how AI can be used to inform treatment decisions in the cardiology unit.

War exacerbates CVD risk

A systematic review analyzing the cardiovascular impact of nearly two dozen armed conflicts has identified a link between war and an increased incidence of coronary heart disease, cerebrovascular and endocrine diseases, and other risk factors among civilians.

MI survivors live longer if they have an active sex life

A study out of Israel has concluded heart attack survivors with an active sex life are better off than their less-active counterparts in the years following an MI, Reuters Health reported August 1.

Long-lost CMAH gene could be responsible for humans’ predisposition to CVD

A gene wiped out by evolution a few million years ago might be the culprit behind humans’ apparent predisposition to heart disease, researchers at the University of California, San Diego School of Medicine have found.

Deadly spider venom minimizes CV damage after heart attack

Researchers in Australia are in the process of converting a deadly local spider’s venom into a drug that could be used to reduce heart damage after an MI.

Testosterone replacement therapy hikes risk of MI, stroke in men

Men taking testosterone replacement therapy for age-related hypogonadism are at an increased risk for ischemic stroke, transient ischemic attack and myocardial infarction, especially during their first two years of use, researchers report in the American Journal of Medicine

Eleven medical societies have signed on to a consensus statement aimed at standardizing imaging for suspected cardiovascular infections.

Kate Hanneman, MD, explains why many vendors and hospitals want to lower radiology's impact on the environment. "Taking steps to reduce the carbon footprint in healthcare isn’t just an opportunity," she said. "It’s also a responsibility."
