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.

Low levels of good cholesterol risk for heart disease

According to the latest research reducing the amount of "bad cholesterol" (LDL - low density lipoprotein cholesterol) in the blood is incidental if the proper amount of "good cholesterol" (HDL - high density lipoprotein cholesterol) is not present.

Clinical trials for diabetes drugs should measure outcomes important to patients

Most clinical trials for new diabetes drugs do not consider the impact medication will have on a patient's quality of life or other outcomes that are important to patients, such as the risk of developing complications associated with diabetes, according to a Mayo Clinic commentary in the current issue of The Lancet.

Process of necrosis redefined in landmark study

A new study led by investigators from the University of Pittsburgh School of Medicine demonstrates that the process of necrosis, long thought to be a chaotic, irreversible pathway to cell death, may actually be triggered as part of a regulated response to stress by a powerful protein, SRP-6, that can potentially halt necrosis in its path.
