Why the study?
Does Body Mass Index impact in-hospital mortality in patients undergoing primary PCI for ST segment elevation acute myocardial infarction?
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.
Supports age-adjusted risk assessment in primary PCI; challenges obesity paradox and leaves open causal BMI effects.
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.
