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.

Early blood pressure treatment with candesartan may postpone hypertension

A new study offers intriguing insight into the possibility of postponing hypertension among the 59 million Americans whose blood pressure is slightly high.

Research finds blood type, age may be pivotal in transfusion success

The controversial practice of blood transfusions for patients suffering from cardiac episodes may lead to an increased risk of mortality, and may be correlated to transfusion blood type and blood age, according to research presented at the American College of Cardiology Annual Scientific Session.

Bariatric surgery may reduce risk of heart disease

"We believed the surgical patients would have a modest reduced risk, but instead we discovered there are significant and long-lasting heart benefits for this group," Dr. Batsis says.

New brain chemical test to predict heart attack yet appropriately used

A new brain chemical test that predicts which patients with heart attack symptoms are at higher risk of dying is paradoxically not being used in younger, healthier patients who could benefit the most from the prognostic information provided by this test

Diabetics benefit less from anti-hypertensive treatment to reduce enlarged heart

Standard blood-pressure-lowering treatment to reduce dangerously enlarged hearts is much less effective and less beneficial in diabetic vs. nondiabetic patients, a team led by NewYork-Presbyterian Hospital/Weill Cornell Medical Center researchers reports in this month's issue of Circulation.

Carotid stenting beneficial for patients with disease but no symptoms

Results from the largest-ever multi-center U.S. registry on the efficacy of carotid stenting shows that the procedure is safe in patients who are at high risk for standard surgical therapy.

Vaccinated adults less likely to die from pneumonia

Adults hospitalized for pneumonia who have received the pneumococcal vaccine are at a lower risk of dying from the disease than those who haven't been vaccinated, according to an article in the April 15 issue of Clinical Infectious Diseases.

Forget the bathroom scales and get out the tape measure!

A new study has found that waist measurements are a better indicator of cardiovascular disease (CVD) than body mass index (BMI).

Fondaparinux significantly reduces risk of death for heart attack patients

Heart attack patients who have a certain pattern on an electrocardiogram significantly reduced their risk of death and having another heart attack at 30 days with the medication fondaparinux, without an increased risk of bleeding and strokes

Therapy for slightly raised blood pressure delays hypertension

A new study shows by giving a blood pressure drug to people with measurements above normal but not yet considered too high, the development of hypertension might be delayed.

Statin drug reverses heart disease

Researchers say a high dose of a cholesterol-lowering statin drug can reverse the build-up of plaque in coronary arteries.

Salt substitution in rural China would cut hypertension rates

A salt substitute specially formulated to be flavourful and effective has significantly reduced blood pressure among high-risk residents of northern, rural China, where home-pickled foods are a dietary mainstay and hypertension is rampant.

Researchers evaluate efficacy, safety of anti-clotting drugs

Patients admitted to the hospital with an acute coronary syndrome (ACS) are often treated with a catheter-based procedure known as percutaneous coronary intervention, or PCI.

One stent may be as good as two

Cardiologists increasingly use non-invasive methods to treat patients with diseased arteries that previously required open-heart surgery.

The safety and effectiveness of fondaparinux for heart attacks

The results of a large international cardiovascular trial will shed light on whether the addition of a new drug that prevents blood clotting, or thrombosis, can improve the treatment of the most serious form of heart attacks.

Driving times and distances to hospitals with percutaneous coronary intervention in the United States

Diverting ambulances with patients suffering a heart to a hospital providing emergency angioplasty rather than a closer hospital with no ability to provide this specialized care, may be feasible for the majority of Americans

Wireless transmission of eletrocardiograms to a cardiologist's hand-held device from ambulance cuts time to direct clot removal

When emergency medical technicians (EMTs) wirelessly transmit eletrocardiograms (ECG) directly to a cardiologist's hand-held device, heart attack patients can potentially receive direct clot removal in half the usual time, according to cardiologists at Duke University Medical Center and NorthEast Medical Center, Concord, N.C.

Innovative treatment for critical limb ischemia

A new randomized study presented at the American College of Cardiology's 55th Annual Scientific Session investigates an innovative treatment for critical limb ischemia, or lack of arterial blood supply and oxygen to the legs, using a therapeutic approach to generate new blood vessels.

Researchers find viable new sources for stem cell transplants to the heart

Stem cell transplantation is among one of the most exciting and hotly debated areas of medical research today. While the promise of personalized medicine and effective treatments for debilitating diseases drive progress in this area, moral and ethical dilemmas about embryonic cells continues to cloud the field.
