Heart Attack (Myocardial Infarction) News and Research

RSS

A Heart Attack (Myocardial Infarction) occurs when blood flow to a section of heart muscle becomes blocked. If the flow of blood isn’t restored quickly, the section of heart muscle becomes damaged from lack of oxygen and begins to die.

Heart attack is a leading killer of both men and women in the United States. But fortunately, today there are excellent treatments for heart attack that can save lives and prevent disabilities. Treatment is most effective when started within 1 hour of the beginning of symptoms. Heart attacks occur most often as a result of a condition called coronary artery disease (CAD). In CAD, a fatty material called plaque (plak) builds up over many years on the inside walls of the coronary arteries (the arteries that supply blood and oxygen to your heart). Eventually, an area of plaque can rupture, causing a blood clot to form on the surface of the plaque. If the clot becomes large enough, it can mostly or completely block the flow of oxygen-rich blood to the part of the heart muscle fed by the artery.

'Seeing' stem cells helps in fight against peripheral arterial disease

Interventional radiologists are fitting together the puzzle pieces of how to use stem cells to create new or more blood vessels to treat peripheral arterial disease (PAD) in those individuals with extensively narrowed or clogged arteries.

Study links inflammation and calcium signaling in heart attack

A new study led by University of Iowa researchers has found an unexpected new link between this inflammation in heart muscle following a heart attack and a previously known enzyme called calcium/calmodulin-dependent protein kinase II or CaM kinase II.

New procedure for eliminating reblockage of arteries

An easily implementable technique to avoid reblockage of arteries that have been cleared through angioplasty and stent insertion has been developed by researchers led by Prof. Boris Rubinsky of the Hebrew University of Jerusalem.

Number of cardiovascular risk factors could determine safety of IVIg treatment

New research out of Wake Forest University School of Medicine identifies the presence of cardiovascular risk factors as an indicator of how likely it is that elderly, hospitalized patients who receive intravenous immunoglobulin (IVIg) treatment will have a stroke or heart attack.

Dermatologists caution that severe cases of psoriasis can be associated with other serious medical conditions

On the surface, the thick, red, scaly, itchy plaques of psoriasis - which have been shown to have a significant negative impact on a person's overall quality of life - may not appear to pose a serious health risk for patients. However, a growing body of research suggests that psoriasis patients are at an increased risk of developing serious medical conditions, including cardiovascular disease and diabetes, particularly when their psoriasis is severe.

History of major depression increases risk for heart disease more than genetics or environment

A history of major depression increases the risk of heart disease over and above any genetic risks common to depression and heart disease, according to researchers at Washington University School of Medicine in St. Louis and the VA.

Heart attack outcomes worse for blacks than whites due in part to individual characteristics

Black heart attack patients have worse outcomes than their white counterparts in large part because of preexisting chronic health conditions and socioeconomic factors, according to a study published in the March issue of Annals of Internal Medicine, Reuters Health reports.

Certain combined medications after heart attack may increase risk of death

Following an acute coronary syndrome such as a heart attack or unstable angina, patients who receive a medication to reduce the risk of gastrointestinal bleeding that may be associated with the use of the antiplatelet drug clopidogrel and aspirin have an increased risk of subsequent hospitalization for acute coronary syndrome or death, according to a study in the March 4 issue of JAMA, the Journal of the American Medical Association.

The obesity paradox

It's called the obesity paradox. Although obese people are more apt to suffer from inflammatory diseases, such as diabetes, heart disease, and stroke, they are also more likely to survive a major attack caused by one of those conditions.
