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.

Epidemiological study links heart protection with non-aspirin, non-steroidal drugs

It is well known that aspirin, a non-selective, non-steroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX), reduces the risk of heart attack and stroke.

High rate of heart attack amongst ethnic minorities in Scotland

The incidence of heart attack amongst Scots of Indian and Pakistani origin is 60-70% higher when compared with non-South Asians, a new report led by the University of Edinburgh has shown.

Slower care for heart attack patients treated after hours and on weekends

Heart attack patients treated with primary percutaneous intervention (PCI) at hospitals after hours and on weekends wait longer to receive clot busters and other treatments and have a higher risk of death than those treated during regular hospital hours

Separate studies produce conflicting results on race and gender disparities in U.S. health system

Two newly released studies in the U.S. have to some extent come to conflicting results. According to one study, by researchers at Emory University, attempts over the last decade to address race and gender disparities in the treatment of U.S. patients hospitalized for heart attacks, still in some respects raise cause for concern.

Treatment of U.S. patients hospitalized for heart attacks continues to vary according to sex and race

Despite a decade of initiatives to remedy health disparities in cardiovascular medicine, at least some aspects of the treatment of U.S. patients hospitalized for heart attacks continues to vary according to sex and race, according to a study by researchers at Emory University in collaboration with Yale University and other centers.

New study shows even non-prescription painkillers raise blood pressure in women

According to a new U.S. study women who take higher doses of common, over-the-counter painkillers, such as Ibuprofen and even Tylenol, have higher blood pressure than women who do not.

Complications from angioplasty much lower among patients whose doctors perform a large number of those procedures each year

Before patients get their clogged heart arteries re-opened, they may want to ask their doctor just how many such procedures he or she has done, a new study finds. The answer may make a big difference in each patient's risk of suffering a major setback before leaving the hospital.

Psychologists find that two different thought processes can explain how we gauge our risk of disease

Psychologists have gained insight into how people judge their personal health risks. The findings suggest that people aren't horribly off the mark as long as they do not rely on media reports and stick to what's happened to people they know.

Electron-beam computed tomography best for evaluating adults with congenital defects in the heart arteries

Electron-beam computed tomography (EBCT) is more accurate than conventional catheter angiography for identifying which adult patients face the greatest risk of sudden death from congenital abnormalities in the arteries supplying blood to the heart, according to a study in the September 2005 issue of Catheterization and Cardiovascular Interventions: Journal of the Society for Cardiovascular Angiography and Interventions.

Fluorescence spectroscopy able to detect the presence of inflammatory cells that are associated with critical atherosclerotic plaques

Because atherosclerotic plaque typically builds up without symptoms and leads to more than 1 million deaths in America each year, the search is on to develop early detection devices that will enable physicians to offer treatment before the disease progresses to advanced stages.

Ground-breaking discoveries that provide hope of an alternative treatment option for haemophilia sufferers

Haemophilia is a hereditary blood disease, primarily affecting males, where the blood fails to clot causing potentially life-threatening 'bleeds'. About one in 6000 Australian males is born with haemophilia in severe, moderate or mild form. People with haemophilia rely on intravenous infusion of recombinant Factor VIII clotting protein.

Latest findings on aspirin resistance

Treatment failures occur with any drug and aspirin is no exception. Evidence is growing that some people will not respond to the anti-coagulant action of aspirin and the drug will not protect against cardiovascular events despite its regular intake.

Drinking a cup of cocoa can prevent potentially fatal blood clots

Throughout history, cocoa has been described as a medicine for many ailments. New research suggests that cocoa may also have a beneficial effect on heart disease and stroke.

People with prehypertension are at much higher risk of heart attack

Normal blood pressure is lower than 120/80 millimeters of mercury (mm Hg). Prehypertension is systolic blood pressure between 120 and 139 and/or diastolic pressure between 80 and 89 mm Hg. (Systolic pressure is the force in the arteries when the heart beats and diastolic pressure is the force when the heart is at rest.) Hypertension is blood pressure 140/90 mm Hg or higher.

FDA approval for Diovan (Valsartan)

Novartis Pharmaceuticals Corporation announced today that the US Food and Drug Administration (FDA) approved Diovan (valsartan), the most prescribed ARB (angiotensin receptor blocker) in the US and worldwide, for a new indication to reduce cardiovascular death in patients at high risk (with left ventricular failure or left ventricular dysfunction) following a heart attack.

New guidelines to help physicians treat and prevent heart attacks

A University of Cincinnati (UC) physician is the lead author of new, simplified guidelines designed to help physicians treat and prevent heart attacks.

Possible early warning system for heart problems

By using sound waves Mayo Clinic researchers have described subtle changes in the motion of the heart that are measurable by ultrasound and may improve understanding of heart function, and possibly be a noninvasive aid in predicting impending heart damage including heart attacks.
