Description
Obesity is an important public health problem, especially among patients with cardiovascular disease. However, little is known about the impact of obesity on the long-term prognoses of patients with acute myocardial infarction (AMI). Major adverse cardiac and cerebrovascular events (MACCE) consist of all causes of death, stroke, target lesion revascularization, target vessel revascularization, non-fatal myocardial infarction, and hospitalization. From January 2001 to March 2005, we analyzed 121 patients who survived [30 days after suffering their first AMI of the left anterior descending artery for MACCE. The mean follow-up period for this study was 59 ± 26 months. Seventy-five patients presented with normal weight (BMI\25 kg/m2) and 46 were obese (BMI[25 kg/m2). During the follow-up period, 56 patients presented MACCE, including 18 deaths, 11 strokes, and seven non-fatal myocardial infarctions. Normal weight was significantly associated with the occurrence of MACCE (p = 0.012). Grouping of the patients by BMI and homeostasis model assessment ratio (HOMA-R) indicated that the combination of a higher BMI ([25) and lower insulin resistance (HOMA-R\2.0) provided the best prognosis (p = 0.0006). Kaplan–Meier curves stratified to the four groups, sorted by diabetes mellitus and BMI at admission, showed that the normal weight patients with diabetes mellitus presented the highest risk of MACCE (p\0.0001). Patients with higher BMI and no insulin resistance or diabetes mellitus present better long-term outcomes following anterior AMI.
