Does Body Mass Index impact in-hospital mortality in patients undergoing primary PCI for ST segment elevation acute myocardial infarction?
The observed 'obesity paradox' in STEMI patients undergoing primary PCI appears to be confounded by age rather than a protective effect of BMI itself on in-hospital mortality.
BMI itself had no impact on in-hospital mortality in patients undergoing primary PCI for AMI. The phenomenon ;obesity paradox' may be explained by the fact that obese patients were younger at presentation.
Kosuge et al. (Mon,) studied this question.
