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.

Bacteria in plaque may increase risk for heart attacks

Researchers have found evidence that the amount of bacteria in subgingival plaques, the deep plaques in periodontal pockets and around the teeth, may contribute to an individual's risk of a heart attack, according to two studies appearing the Journal of Periodontology.

Narcotic medications can safely and effectively ease severe, chronic pain in older people

Narcotic medications can safely and effectively ease severe, chronic pain in older people with little risk that these patients will seek ever-increasing doses, University of California, San Francisco (UCSF) medical scientists have found. Younger patients, however, are likely to want to rapidly increase their medication dose, the researchers found, posing serious potential health consequences.

Two out of three Americans with type-2 diabetes do not have their disease under control

According to a new survey two out of three Americans with type-2 diabetes do not have their disease under control and are putting themselves at risk of early deaths from stroke, heart attack or kidney failure as well as blindness and limb loss.

Cardiovascular risk factors among homeless people are under-treated in Canada

The study, the first comprehensive assessment of cardiovascular risk factors in a representative sample of homeless adults, also found that cardiovascular risks among the homeless may be underestimated due to commonly used risk assessment tools that do not account for cocaine use and the level of smoking exposure.

Hypertension drug combination yields high rate of blood pressure control in hard-to-treat patients

The study, conducted at the University of Maryland School of Medicine and 118 other sites, was focused on bringing down systolic blood pressure, the top number in a blood pressure reading, which is the more difficult number to bring down.

Routine, inexpensive blood test sharpens heart disease risk predictions

Routine measurements of white blood cell counts that provide a ratio of neutrophils to lymphocytes may offer a simple and low-cost way to refine predictions of heart attack or death, according to a new study in the May 17, 2005, issue of the Journal of the American College of Cardiology.

A drug that controls blood pressure and reduces heart risk also appears to protect against diabetes

In new results from the VALUE trial that pitted the drug valsartan against another blood pressure drug, amlodipine, the patients taking valsartan were found to have a 23 percent lower risk of developing diabetes during the four or more years of the study.

Tamoxifen study counters hopes that drug might protect the heart

Despite previous studies hinting at tamoxifen's potential benefit for breast cancer survivors' heart health, California researchers have found that the breast cancer drug does not decrease survivors' risk of heart attack.

Statin therapy is cost-effective for a wider range of individuals with vascular disease or diabetes than previously recognised

Current guidelines generally recommend the initiation of statin therapy when the estimated 10-year risk of a non-fatal heart attack or coronary death is at least 15-20%.

New trend in treating heart disease in diabetics - angioplasty using the Cypher Sirolimus-eluting coronary stent

The World Health Organisation has predicted an increase in the worldwide prevalence of diabetes of epidemic proportions . Eighty percent of people with diabetes will die from cardiovascular complications -- stroke and/or coronary heart disease (CHD).

Aspirin aids recovery following heart bypass surgery

Many patients who regularly take aspirin to thin their blood prior to undergoing coronary artery bypass surgery, have in the past been told to stop the aspirin a week before the operation, but new research has found that they may be better off taking it.

Drug lowers inflammatory markers associated with risk for heart attack

A preliminary study suggests that use of a drug that inhibits a specific protein in patients with certain genetic variants that increase their risk for heart attack reduced their levels of inflammatory markers associated with heart attack risk, according to a study in the May 11 issue of JAMA.

No glass ceiling for women when it comes to dying from heart disease, say experts

While many of us assume that heart disease mainly strikes men, the fact is 12,000 Australian women die each year from illnesses like stroke, heart attack and heart failure - that's four and a half times the number of lives claimed by breast cancer.

Cocaine use increases the risk of coronary aneurysms

Researchers in Minnesota say that cocaine users may be putting themselves at risk of coronary aneurysms, a ballooning of the walls of coronary arteries, which is potentially fatal.

New study suggests Pioglitazone HCl may significantly improve key predictors of cardiovascular risk

Study results published in the May 17th issue of Circulation, the journal of the American Heart Association, found that the diabetes medication pioglitazone HCl reduced carotid artery intima-media thickness (IMT). Patients taking pioglitazone also experienced significant reductions in insulin resistance, C-reactive protein (a marker for inflammation) and blood pressure, all of which contribute to the overall risk for cardiovascular disease.
