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.

Moderate alcohol intake reduces the risk of dementia in seniors

A glass of wine here, a nightcap there - new research out of Wake Forest University School of Medicine suggests that moderate alcohol intake offers long-term cognitive protection and reduces the risk of dementia in older adults. The study is being presented at the Alzheimer's Association 2009 International Conference on Alzheimer's Disease (ICAD), in Vienna on July 13.

FDA approves Effient (prasugrel) for heart attack in angioplasty patients

The U.S. Food and Drug Administration has approved the blood-thinning drug Effient tablets (prasugrel) to reduce the risk of blood clots from forming in patients who undergo angioplasty, a common procedure to unblock a clogged coronary artery.

Dialysis treatments OK for patients who have had a heart attack

Dialysis treatments do not affect the heart health of kidney disease patients who have had a heart attack, according to a study appearing in an upcoming issue of the Clinical Journal of the American Society Nephrology (CJASN). Since cardiovascular disease is the most common cause of death in kidney disease patients, the findings are good news for individuals who need the treatments.

Atrial fibrillation linked to increased hospitalization in heart failure patients

Patients with atrial fibrillation, common in those with advanced chronic heart failure, have an increased risk of hospitalization due to heart failure, according to new research from researchers at the University of Alabama at Birmingham (UAB).

Delirium in hospitalized adults: Situation critical, no relief available

Every year as many as seven million adults in the United States experience delirium during hospitalization. In a systematic review of the scientific literature on delirium prevention and treatment, investigators from the Regenstrief Institute, Indiana University, and Wishard Health Services found that despite the significant health and financial burdens of delirium for hospitalized adults, no effective way to prevent or treat the condition has been identified.

How ‘high carb’ foods cause heart attacks

It has been commonly known for a number of years that certain foods, such as white bread and corn flakes, are bad for cardiac health, but new research from Israeli scientists shows just how 'high carb' foods cause heart attacks.

Heart attacks kill 10,000 Australians each year and many could be avoided

A new report by Access Economics has revealed that this year 80,000 Australians can expect to be treated in hospital for heart attacks or chest pain - at a cost to the economy of $18 billion and 10,000 people will die from a heart attack.

Telehealth interventions for the secondary prevention of coronary heart disease

The use of phone and internet between patients and healthcare providers is an effective way to reduce risk factors for coronary heart disease and the risk of further events after a heart attack, according to new research published today in the June issue of the European Journal of Cardiovascular Prevention & Rehabilitation.

Genomic discovery: Protecting kidney function during heart failure

Mayo Clinic cardiology researchers have found a peptide that helps preserve and improve kidney function during heart failure, without affecting blood pressure. Earlier variations of this peptide caused blood pressure to drop limiting the potential benefits to the kidneys. The findings appear in the current Proceedings of the National Academy of Sciences.

Skin disease psoriasis associated with cardiovascular disease and increased mortality

The skin disease psoriasis is associated with atherosclerosis (a buildup of plaque in the arteries) characterized by an increased prevalence of ischemic heart disease, cerebrovascular disease, peripheral artery disease and an increased risk of death, according to a report in the June issue of Archives of Dermatology.

High blood pressure among lower-status employees lingers well into retirement

Retirement from some occupations may not provide relief from the potentially devastating health effects of work-related hypertension, according to a new study from UC Davis.

Comparative effectiveness tested in diabetes study, VA records release

A study in the New England Journal of Medicine has found common surgical interventions and stents, the expensive medical devices used in bypass surgeries, are no more effective at preventing death, heart attacks and strokes in diabetic patients than less expensive drugs, the Wall Street Journal reports. The study, which included 2,368 patients, is representative of new interest in head-to-head comparisons of treatments.

Seniors who use cardiac rehabilitation live longer, study finds

Coronary heart disease (CHD) is the leading cause of death worldwide and a major driver of medical and economic costs, especially among older adults. It has long been established that cardiac rehabilitation improves survival, at least in middle-aged, low- and moderate-risk white men. Now a large Brandeis University-led study published in the Journal of the American College of Cardiology reports that older cardiac patients benefit as much from cardiac rehab as their younger counterparts.

Diabetes with coronary disease: A moving target amid evolving therapies

In an editorial in the current issue of the New England Journal of Medicine (NEJM), William E. Boden, M.D., professor of medicine and preventive medicine at the University at Buffalo, recommends that the results of the BARI-2D Trial published in that edition must be interpreted with "considerable caution."

Fatigue common after heart attack

Half of all patients who undergo myocardial infarction (heart attack) are experiencing onerous fatigue four months after the infarction. The patients who are most fatigued are those who perceive the infarction as a sign of chronic illness, those who experience the illness as difficult to control, and those who believe that the illness has a large impact on their life. These are the conclusions of a thesis presented at the Sahlgrenska Academy, University of Gothenburg, Sweden.

Stopping fatty change in heart cells

Heart failure is one of the world's most frequent causes of death - caused by conditions such as diabetes and obesity. With people who are overweight, the heart has to do more work in order to pump the blood through the circulatory system and this causes an increase in blood pressure.

Importance of preventing vascular congestion in heart failure

Preventing vascular congestion is an important mediator in heart failure, reports a study in the June issue of the Journal of Cardiac Failure, published by Elsevier.

Obesity and diabetes each double the risk of heart failure - patients with both conditions ‘very difficult’ to treat

The twin epidemics of obesity and type 2 diabetes will continue to fuel an explosion in heart failure, already the world's most prevalent chronic cardiovascular disease, according to John McMurray, professor of cardiology at the Western Infirmary, Glasgow, and President of the Heart Failure Association. He reported that around one-third of patients with heart failure have evidence of diabetes, and for them the outlook is very serious. For doctors, he added, effective treatment is "very difficult".
