Heart rate recovery from exercise reveals risk of attack

Ever wonder how healthy your heart is? There's a fairly easy way to get an accurate answer, says Men's Health magazine, citing a recent study in the New England Journal of Medicine.

After following over 5,700 men for 23 years, researchers concluded that the faster your rate drops after exercise, the lower your risk of dying of a heart attack. To perform the calculation, first take note of your heart rate at exactly one minute after you've finished your workout. Then, take that number and subtract it from the maximum heart rate you reached during the workout. If the difference is more than 35bpm, there's a good chance you do not face an increased risk.

If, however, it is less than 35bpm, the study suggests there's need for caution. Specifically, if the difference is between 31-35bpm, your risk is increased by 40 percent; 25-30bpm, risk increase is 30 percent; less than 25bpm, risk increase is 110 percent.
