heart attack

An erroneous story on a citizen journalism site saying CEO Steve Jobs has had a heart attack prompts a sell-off of Apple shares.

An Internet report claiming that Apple chief executive Steve Jobs has had a heart attack is not true, the company said on Friday.

(Ohio State University) Researchers have identified specific damages to the brain that may occur when heart attack victims are socially isolated from others.

The study in mice found that those animals that lived alone before undergoing a heart attack showed five to eight times more damage to neurons in one part of the brain than did similar animals that lived with others.

Machines on cell surfaces, mechanical and lifeless as bed springs, protect blood vessels by responding to blood flow force, according to research published today in the Journal of Cell Biology.

By sensing and reacting to force, such machines interfere with inflammatory pathways central to atherosclerosis, the leading cause of heart attack and stroke.

The next set of studies will seek to "tweak" the process with the goal of designing a new class of therapies.

Adiponectin, a protein produced by fat cells, may play a pivotal and counterintuitive role in cardiovascular health for older Americans according to a new study.

Patients treated solely with medications after suffering from chest pain, heart attack or coronary artery disease are more likely to die during the first year following their initial hospitalization.

Researchers found that with all else being equal, the risk of death was highest for the medically managed group and lowest for patients who underwent stenting.

Biophysics researchers are trying to reduce post-heart attack damage by studying the way cells die in the heart -- a process controlled by transcription factors.

Even if you eat right and exercise regularly, chances are high that you'll still die of a heart attack or stroke.

But thanks to new findings the odds may finally shift in your favor. Two unrelated studies on atherosclerosis that have the potential to save millions of lives.

Acute kidney injury, a common complication of cardiac surgery during hospitalization, is linked to increased and prolonged risk of death in heart attack patients who have been discharged from the hospital, according to a study published in Archives of Internal Medicine.

An analysis of studies involving the use of hemoglobin-based blood substitutes indicates their use is associated with an increased risk of death and heart attack, according to a new article.
