Washington, Apr 29 : A cheap method of predicting who is at greater risk of dying suddenly and unexpectedly from a heart attack has been developed by researchers in France.
In a study of 7746 French male civil servants, published in Europe''s leading cardiology journal, the European Heart Journal, the researchers found that men whose heart rate increased the most during mild mental stress just before an exercise test had twice the risk of dying of a sudden heart attack in later life than men whose heart rate did not increase as much.
The study is the first to discover this association and since taking a patient''s pulse is an easy and inexpensive procedure, it suggests a way of identifying people who may be at increased risk.
