Obese patients have a greater chance of survival following a myocardial infarction (MI) than those with a normal body mass index, claim the authors of a controversial study.
German and Swiss researchers followed-up 1,676 patients admitted to hospital with unstable angina/non-ST-segment elevation MI. After three years, they found obese and very obese patients had less than half the long-term mortality than those of normal weight.
But June Davison, a cardiac nurse at the British Heart Foundation, said the research raised more questions than it answered. 'This research does not explain the reasons for a link between obesity and improved survival rate,? she said. 'It?s far better to prevent the problem arising at all.?
