Abstract:
Objective To investigate the impact of body mass index (BMI) on short-term and long-term prognosis in the patients with ST-segment elevation myocardial infarction (STEMI).Methods The clinical data of inpatients with STEMI in our hospital during 2014 were retrospectively collected.The patients conforming to the inclusion and exclusion criteria were divided into 4 groups according to BMI,low BMI group (n=31),normal BMI group (n=139),overweight group (n=71) and obesity group(n=26).The clinical baseline data were analyzed and compared among 4 groups,and the all-cause mortality on 7 d and within 1 year after myocardial infarction(MI) was followed up.Results The higher the BMI increased,the younger the patient's onset age (P＜0.01),the smaller the female proportion(P=0.001),among them,the albumin and hemoglobin levels in the obesity group were relatively higher(P=0.004;P =0.006);the all-cause mortality at 1 year after MI was significantly decreased with BMI increasing (P =0.003),while which on 7 d after MI had no statistical difference (P=0.287).Conclusion BMI is correlated with the long-term prognosis in the patients with STEMI,and "obesity contradiction" phenomenon exists in the patients with STEMI.However,the influence of BMI on the prognosis in the patients with STEMI should be comprehensively evaluated by combining with the multiple factors such as the patient's age,sex,complications and medication therapy.
