No correlation between body mass index and 30-day prognostic outcome in Asians with acute ST-elevation myocardial infarction undergoing primary coronary intervention

摘要

Abstract Background This study investigated whether body mass index (BMI) was a risk factor predictive of 30-day prognostic outcome in Asians with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). Material and methods Data regarding the impact of {BMI} on the prognostic outcome in Asian populations after acute {STEMI} is scarce. A number of 925 {STEMI} patients were divided into three groups according to the BMI: normal weight (<25?kg/m2), overweight (≥25.0 to <30.0?kg/m2) and obese (≥30.0?kg/m2). Results The obese group was significantly younger with significantly higher incidences of smoking and diabetes mellitus. The incidences of multi-vessel disease, final thrombolysis in myocardial infarction (TIMI)-3 flow, advanced Killip score, advance congestive heart failure, 30-day mortality and combined 30-day major adverse clinical outcome (MACO) did not differ among the three groups. Multiple regression analysis showed the age, unsuccessful reperfusion and lower left ventricular ejection fraction were most significant and independent predictor of 30-day mortality. Conclusion {BMI} is not a predictor of 30-day prognostic outcome in Asians with {STEMI} undergoing primary PCI.
