A new study by NYU Langone Medical Center researchers identified a new culprit that leads to atherosclerosis, the accumulation of fat and cholesterol that hardens into plaque and narrows arteries. The research explains why cholesterol-laden, coronary artery disease-causing cells called macrophages, accumulate in artery plaques.
In a study that enrolled nearly 30,000 apparently healthy men and women, those who had an increase in their resting heart rate over a 10-year period had an increased risk of death from all causes and from ischemic heart disease, according to a study in the December 21 issue of JAMA.
In a new study, NYU Langone Medical Center researchers have discovered how cholesterol-lowering drugs called statins promote the breakdown of plaque in the arteries.
Highlights: 1) Two similar blood pressure–lowering drugs could have different effects on dialysis patients’ heart health. 2) Angiotensin receptor blockers are more effective at fighting inflammation while angiotensin converting enzyme inhibitors are better at preventing blood vessel damage. Both properties could help prevent heart disease. 3) About 20% of kidney disease patients die within one year after they start dialysis and more than half die after five years—mostly from heart disease.

Coronary calcium in heart arteries provides important clues about risk, even among younger and elderly patients and those without traditional risk factors, according to new studies.
If your doctor says you have a negative stress test, or that your cholesterol or blood pressure are normal, how assured can you be that you’re not likely to have a heart attack in the next seven to 10 years? Assessing traditional risk factors, such as age, high blood pressure, cholesterol, smoking and family history can estimate a person’s risk, but the picture is not always clear-cut. Some newer tests can be offered to provide reassurance or guidance about the need for medications or further testing.

A new study from researchers at the Perelman School of Medicine at the University of Pennsylvania suggests that cardiovascular disease may be an unfortunate consequence of mammalian evolution.
After a heart attack, women’s hearts are more likely to maintain their systolic function—their ability to contract and pump blood from the chambers into the arteries. This suggests that heart disease manifests differently in women, affecting the small blood vessels, instead of the major blood vessels as it does in men.
A Loyola University Chicago Stritch School of Medicine study could lead to improved gene therapies for conditions such as heart disease and cancer as well as more effective vaccines for tuberculosis, malaria and other diseases.
A long-held mantra suggests that you can't change your family, the genes they pass on, or the effect of these genes. Now, an international team of scientists, led by researchers at McMaster and McGill universities, is attacking that belief. The researchers discovered the gene that is the strongest marker for heart disease can actually be modified by generous amounts of fruit and raw vegetables. The results of their study are published in the current issue of the journal PLoS Medicine.

Each year in the United States, more than 200,000 people have a cardiac defibrillator implanted in their chest to deliver a high-voltage shock to prevent sudden cardiac death from a life-threatening arrhythmia. While it’s a necessary and effective preventive therapy, those who’ve experienced a defibrillator shock say it’s painful, and some studies suggest that the shock can damage heart muscle.
Researchers at the Cardiac & Vascular Institute at NYU Langone Medical Center have identified a hidden culprit in the battle against women’s heart disease. Plaque disruption, a rupture or ulceration of cholesterol plaque in a coronary artery, has been discovered as the mechanism behind myocardial infarction (heart attack) in some women without significant coronary artery disease (CAD) – that is, open rather than closed arteries on an angiogram. The study is published in the September 27th issue of the journal Circulation.
New York City, NY (September 22, 2011) – The first weeks of school are stressful enough on children, but how much more so for children with underlying heart problems. Parents of children who have been diagnosed with cardiac problems such as a heart murmur or irregular heart beat, or whose family has a history of heart problems, should be specially vigilant. The following information from the Pediatric Heart Center of The Children’s Hospital at Montefiore should be considered by parents of children at risk for heart disease:
Among patients with acute coronary syndromes undergoing a procedure such as angioplasty, those who received platelet function tests before receiving antithrombotic therapy to determine appropriate clopidogrel dosing and who had high residual platelet reactivity (platelets resistant to antithrombotic therapy) were at an increased risk of an ischemic event at short- and long-term follow-up of up to 2 years, according to a study in the September 21 issue of JAMA.
While the incidence of the life-threatening condition of aortic dissection is significantly higher than in the general population, it remains low among patients with the congenital heart defect, bicuspid aortic valve; however, the incidence of aortic aneurysms is significantly high, according to a study in the September 14 issue of JAMA.
