Executive Summary
Failure to achieve maximum heart rate during exercise testing predicts heart attack and death, according to the Framingham-Cleveland Clinic study. During eight-year follow-up of 1,575 men, 14% of those who had failed to reach their predicted maximum heart rate on a treadmill went on to suffer a heart attack, sudden death or angina. Only 3% of those who reached the heart rate target suffered adverse cardiac events, writes Dr Peter Okin in Circulation (April).
