Alcohol Intake Lowers Risk of Heart Disease But … Increases Risk of Breast Cancer?

November 10, 2011 | by

A study published this week in the Journal of the American Medical Association suggests that even moderate alcohol consumption — as little as one-half to one drink per day — increases a woman’s risk of breast cancer by about 15% [1]. Daily consumption of two or more drinks per day (where a “drink” contains about 14 grams of pure alcohol, and results are independent of the type of drink consumed) increases breast cancer risk by 50%. These results suggest a much stronger effect of low to moderate alcohol consumption on lifetime breast cancer risk than previous studies [2-4] have done.

Exercise Intensity, Not Quantity Reduces Risk of Death from Heart Disease

September 7, 2011 | by

New research suggests that the intensity of exercise might be more important than the quantity in helping to prevent death from heart disease and other causes.

In a study presented last week at the European Society of Cardiology Congress 2011, scientists described new research that examined the relationship between exercise duration, exercise intensity, and total risk of death [1]. Lead researcher Peter Schnohr of Copenhagen, Denmark explained that both male and female cyclists had a decreased total risk of death if they cycled vigorously (by their own perception), but that cycling duration didn’t show a similar protective effect.

Scientists Learn Why a Little Alcohol Can Be Good For You

April 7, 2011 | by

A number of studies have asserted that moderate drinking has a positive benefit on cardiovascular health. Now, scientists at the University of Rochester Medical Center have discovered how alcohol consumption can help to prevent heart disease. The research, published in the journal Arteriosclerosis, Thrombosis and Vascular Biology, studied the effects of moderate amounts of alcohol in human coronary artery smooth muscle cells and in the carotid arteries of mice [1]. In both cases, regular, limited amounts of alcohol inhibited a protein called Notch 1 and prevented the buildup of smooth muscle cells in blood vessels that leads to the narrowing of the arteries and can put you at risk for a heart attack or stroke.

Abnormal Heart Rate Turbulence May Predict Heart Disease

March 2, 2011 | by

According to a study in the February 15 edition of the Journal of Cardiovascular Electrophysiology, abnormal heart rate turbulence is associated with an increased risk of heart disease death in otherwise older, low-risk individuals [1]. Additional studies need to be done in order to understand whether this potential biomarker will be a clinically valuable tool.

Hair Cortisol as a Predictive Biomarker for Heart Attack

September 14, 2010 | by

We all deal with stress. Whether it’s stress from a job, financial, or relationship issues, chronic stress has been linked to an increased risk for developing cardiovascular disease [1-2]. However, there hasn’t been a biological marker that could be used to measure an individual’s level of stress. A recent study performed by researchers at the University of Western Ontario Schulich School of Medicine & Dentistry and published in the journal Stress has found that the level of cortisol in hair can be used as a biomarker to measure chronic stress and the risk of heart attack in men [3].
