Simply measuring a woman’s resting pulse rate can predict how likely she is to suffer a heart attack, says a study in the British Medical Journal. US researchers looked at the records of around 129,000 postmenopausal women who had no history of heart problems. They found that those with the highest heart rates were significantly more likely to suffer a heart attack than the women with the lowest rates. However, the association was weaker than that with cigarettes and diabetes. Previous studies have shown that resting heart rate predicts coronary events in men.
