Cardiorespiratory Fitness
Tuesday, August 18, 2009

A study shows that people with good cardiorespiratory health have a lesser risk of dying not only from heart disease, but from any cause. Dr. Edward Hill discusses more about the studyís conclusions in todayís 60 Second Housecall.

People who are physically fit are less likely to develop heart disease and less likely to die from any cause, a review of studies concluded.

In the review, researchers analyzed the relationship between physical fitness, expressed by cardiorespiratory fitness, and the risk of death found in 33 different studies involving nearly 190,000 people. Cardiorespiratory fitness, or CRF, is measured through exercise stress testing.

The researchers found that compared to those with a high CRF, those with low cardiorespiratory fitness had a 70 percent higher risk of death from any cause and a 56 percent higher risk of heart disease events, such as heart attack or stroke. Compared to those with an intermediate level of physical fitness, those with a low CRF had a 40 percent higher risk of death from any cause and 47 percent higher risk of heart events.

CRF could be useful for prediction of heart disease and all-cause mortality risk in a primary care medical practice.
