News : Physical fitness halves men's heart disease death rate
Webindia123 - India, September 3 2005 -- A new study published in the Journal of the American Heart Association says that being physically fit can dramatically reduce men's deaths from heart disease, even when their cholesterol rates are high.
According to Queen's researcher Peter Katzmarzyk. who led the study, regardless of their cholesterol level, men can cut by half their risk of dying from cardiovascular disease if they are physically fit.
The main aim of the study was to analyze the effectiveness of last year's modifications to the guidelines from the U.S. National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) for lowering bad (LDL) cholesterol to predict death from cardiovascular diseases.
"We wanted to find out if the new guidelines could identify men at risk for cardiovascular disease. We confirmed that the guidelines do accurately identify men at risk not only of disease, but also at risk of cardiovascular death. We also discovered that fitness is important across the board - at every level of cholesterol," said Dr. Katzmarzyk.
The researchers found that within a given risk category, physical fitness is associated with a greater than 50-per-cent lower risk of mortality.
In this study, physical fitness was four to five, 30-minute segments of activity per week: equivalent to walking 130 to 138 minutes per week.
Researchers analyzed the cardiovascular risk factors and cardio-respiratory fitness of men aged between 20 to 79, and foun that there were 179 deaths from cardiovascular disease over more than 10 years of follow-up.
"Lowering the threshold for consideration of cholesterol-lowering drug therapy for those at high risk will ultimately save lives and also have important implications for the healthcare system," said Dr. Katzmarzyk. (ANI)
