A study led by the National University of Ireland, Galway has said that men with angina face far greater heart risks than their female counterparts.
The study analyzed the outcomes in 1,785 patients who were diagnosed with angina between January 1998 and December 2001. During a five-year follow-up period, the researchers found that patients who were male, older and a smoker were at an increased risk of suffering a heart attack.
Male patients were also more likely than female ones to undergo bypass surgery and angioplasty to open up blocked arteries.
"We need to look at what the hell is happening here rather more closely than we have in the past," said lead researcher Dr Brian Buckley. "If you are diagnosed with angina, you should not panic - it won't necessarily end up in a heart attack - but you ought to take what the doctor says to you seriously, both in terms of taking medication and adopting a healthier lifestyle."
The details of the study appear in the British Medical Journal.
