The results of a recent research, indicates that heart patients who are overweight or obese are more likely to survive than the patients with normal weight.

Considering excess weight to be a major risk factor, doctors in general put obese heart patients under aggressive treatment. Scientists opine that this increase in survival rate could be due to the aggressive treatment given to obese people.
Thus, the authors conclude that further research is needed to explain the results of this study.
