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.

Canada province will seize children of drug addicts

Mixed carbon nanotubes and standard urban particulates suggests a risk of thrombosis from airborne pollution

Carbon nanoparticles - both those unleashed in the air by engine exhaust and the engineered structures thought to have great potential in medical applications - promote blood-clotting, scientists report in an upcoming edition of the British Journal of Pharmacology.

Drug-eluting stents significantly cut the rates of heart attack and repeat procedures

The use of medicated stents markedly improves the clinical outcomes of patients who develop blockages in aging veins surgically grafted onto the heart, according to a just-published study in the November 2005 issue of Catheterization and Cardiovascular Interventions: Journal of the Society for Cardiovascular Angiography and Interventions.

More doubt cast on benefit of beta blockers for high blood pressure

A comprehensive study has produced more evidence that a drug widely used to treat high blood pressure may not be the best option for many patients.

New genetic discovery may help explain why some people develop high blood pressure and others don't

It also gives new insight into how the kidneys govern the balance of salt in the body, a crucial task for regulating blood pressure. And, it reveals how a gene already linked to behavior and mental health can play a role in the body, as well as the brain.

Cell phones speed heart attack treatment

A Michigan hospital has cut in half the time it takes to begin life-saving treatment of heart attack patients by using cell phones to transmit electrocardiograms (ECGs) from the field

Very low LDL cholesterol levels appear to be safe for heart patients on statin therapies

"There was no apparent safety concern for patients whose resultant LDL on intensive therapy was lower than current guidelines. There was a trend toward improved clinical outcomes in the lowest LDL groups," said Stephen D. Wiviott, M.D., from Brigham and Women's Hospital in Boston, Massachusetts.

First study to investigate how heat affects people with heart failure

Reduced blood flow to the skin's surface may be a key cause of heat-related illnesses in patients with congestive heart failure, UT Southwestern Medical Center researchers have found.

Obesity linked to dementia and Alzheimer's disease

Individuals who were obese at midlife had an increased risk for dementia later in life compared to individuals of normal weight, according to an article in the October issue of Archives of Neurology.

Electron-beam computed tomography - a more accurate replacement for coronary catheterizations

Electron-beam computed tomography (EBCT) is more accurate than conventional catheter angiography for detecting a dangerous congenital heart abnormality that could cause sudden death, according to research by a Saint Louis University radiologist published last month in Catheterization and Cardiovascular Interventions: Journal of the Society for Cardiovascular Angiography and Interventions.

Screening for cardiovascular risk by measuring blood levels of C-reactive protein should not be advocated

C-reactive protein (CRP) is released by the liver in response to inflammation related to an infection, injury, or conditions such as arthritis. Inflammation also has been associated with the cause and progression of cardiovascular disease, particularly in the build up of fatty deposits in the lining of arteries.

Cost-effectiveness of potentially life-saving implantable cardioverter defibrillators (ICD) is an important public health issue

The use of implanted defibrillators that keep the heart beating in proper electrical rhythm to prevent cardiac arrest appears to be cost-effective for those patients who receive a significant mortality reduction, according to researchers from Duke Clinical Research Institute (DCRI), Stanford University and the VA Palo Alto Health Care System, Calif. They analyzed eight clinical trials of the devices to arrive at their conclusion.

Many people continue to smoke after life threatening event

An international survey published today (Thursday 6 October) in Europe's leading cardiology journal, European Heart Journal, reveals that fewer than half of the heart patients in the study who smoked quit after suffering their first coronary event, with one out of five continuing to smoke despite advice to stop.

Amiloride and spironolactone may help patients with high blood pressure

Two inexpensive but widely overlooked drugs may help many patients who continue to have high blood pressure despite taking standard blood pressure medications, according to research by Indiana University School of Medicine scientists.

Study shows hospitals can streamline procedures to reduce the time they take to treat heart attack patients

The NIH-sponsored study, published in the September Journal of the American College of Cardiology, reports methods for delivery of rapid care based on the experiences of top programs. Studies have found that while every minute counts, few hospitals are able to perform at levels recommended by national guidelines.

Study paves the way for new therapeutic targets which can potentially improve heart disease in patients with end-stage kidney failure

Night-time hemodialysis patients may have a greater capacity to repair their hearts and blood vessels compared to those on conventional dialysis three times a week, according to a study in the October issue of the American Journal of Physiology - Renal Physiology, published by the American Physiological Society.

Johns Hopkins awarded $12 million to study how stem cell therapies can be used to treat hearts damaged by heart attack

Heart specialists at Johns Hopkins Heart Institute have been awarded more than $12 million from the National Heart, Lung, and Blood Institute (NHLBI) to study how stem cell therapies can be used to treat hearts damaged by heart attack or heart failure.

Researchers set out to determine the effectiveness of endomorphin 1, with a painkilling capacity equal to or greater than morphine

Nearly one third of the world's adult population suffers with the pain of arthritis. While NSAIDs and COX-2 inhibitors offer the promise of relief, these drugs also bring the risk of adverse effects, from stomach ulcers to heart attack.

HeartMate XVE left ventricular assist device

Nine years ago this week, a team of University of Michigan doctors gave a dying heart patient a second chance at life by implanting a high-tech pump in his chest. The high-risk procedure was the first in Michigan performed using a new blood-pumping device called a HeartMate XVE left ventricular assist device, which helped the patient live until he received a heart transplant five weeks later.
