Physical Fitness and Heart Attacks

Friday, January 20, 2017

Your level of physical fitness may have an effect on your risk for cardiovascular disease and your chances of surviving a heart attack. Dr. Edward Hill discuss a study on the subject in todays 60 Second Housecall.

Dr. Hill:

Being physically fit may reduce your risk of cardiovascular disease and if you do suffer a heart attack, your exercise regimen could improve your chances of survival.

Thats the conclusion of Johns Hopkins researchers who looked at medical records of more than 2,000 people who had taken a treadmill stress test before their first heart attacks. Each year, about 550,000 Americans have a first-time heart attack.

The study compared the patients metabolic equivalent, or MET scores, a measure of energy consumption at rest and during physical activity, with how well they recovered from a heart attack.

Those with MET scores of 10 to 12, the highest possible, had about 40 percent fewer deaths after a first heart attack compared with the rest of the patients.

A MET score of 1 is equivalent to the energy used to sit on a couch, while a 12 is equivalent to sprinting.

The study also adds to evidence that regular exercise reduces the risk of heart attack and death from all causes, researchers noted.
