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.

Happy Holidays (and watch the cookies!)

December 23, 2010 | by

December can be a fun, joyous season. Families everywhere are celebrating Christmas, Hanukkah and Kwanzaa. Each of these winter holidays brings many festivities and lots of yummy, delicious food. The temptation to eat and drink in excess can be hard to overcome.

Although getting your five-a-day is important for promoting good health, overindulging on anything is bad for you. Indeed, overindulgence — consuming more calories than your body requires — is one of the main factors contributing to weight gain. Many of us love sweets during the holidays, but large portions won’t do anything but add surplus calories that get converted into fat.

Cookies and Santa Claus

Consider Santa Claus. One of the benefits of being “good St. Nick” is eating all the holiday cookies left by children around the world on Christmas eve.

Lifestyle Intervention Improves Risk Factors in Type 2 Diabetes

October 2, 2010 | by

An intensive lifestyle intervention program designed to achieve and maintain weight loss improves diabetes control and cardiovascular disease risk factors in overweight and obese individuals with type 2 diabetes, according to four-year results of the Look AHEAD study, funded by the National Institutes of Health and the Centers for Disease Control and Prevention. The results are published in the Sept. 27, 2010, issue of the Archives of Internal Medicine.
