Heart attacks appear to have become more common in middle-aged women over the past two decades, but all women and especially those younger than 55 have recently experienced a greater increase than men in their chances of survival following such a heart event, according to two reports in the October 26 issue of Archives of [...]

A heart damaged by heart attack is usually broken, at least partially, for good. The injury causes excessive scar tissue to form, and this plays a role in permanently keeping heart muscle from working at full capacity.
Now researchers have identified a key molecule involved in controlling excessive scar tissue formation in mice following a heart [...]

People who have been diagnosed with panic attacks or panic disorder have a greater risk of subsequently developing heart disease or suffering a heart attack than the normal population, with higher rates occurring in younger people, according to new research.
The study found that people who were younger than 50 when first diagnosed had a significantly [...]

Patients with idiopathic pulmonary fibrosis (IPF) are three times as likely to experience severe coronary events—including heart attacks—than people without the disease, according to a recent study that analyzed the risk of cardiovascular disease in nearly 1,000 patients with IPF and more than 3,500 matched controls.
"If you look at them over time, people with IPF [...]

Researchers have discovered one potential mechanism by which briefly cutting off, then restoring, blood flow to arteries prior to a heart attack lessens the damage caused, according to a study published today in the journal Cardiovascular Research. The new mechanism points to how future drugs could provide protection ahead of heart attacks and strokes for [...]

For mini-strokes, or transient ischemic attacks (TIAs), both overdiagnosis and underdiagnosis can be perilous. Overdiagnosis neglects the real underlying illness. Underdiagnosis leaves a patient at risk of a full-fledged stroke. Both expose patients to erroneous therapies with potential side effects.
And yet, TIAs are difficult to assess because, by definition, the neurological dysfunction [...]

Cholesterol crystals released in the bloodstream during a cardiac attack or stroke can damage artery linings much further away from the site of the attack, leaving survivors at greater risk than previously thought.
George Abela, a physician in Michigan State University’s College of Human Medicine and chief of the Department of Medicine’s cardiology section, is leading [...]

It`s not just the stress of going to work. Daily rhythms in the activity of cells that line blood vessels may help explain why heart attacks and strokes occur most often in early morning hours, researchers from Emory University School of Medicine have found.
Endothelial cells serve as the interface between the blood and the arteries, [...]
