目的:探讨代谢综合征(MS)对急性心肌梗死(AMI)左心室重构、心功能变化和30 d心性病死率的预测价值。方法:按NCEP-ATPⅢ标准将113例AMI患者分为MS组(53例)和非MS组(60例),比较2组患者左心室重构、心功能和30 d心性病死率。结果:MS组左心房内径、左心室舒张末期内径、左心室质量指数、左心室舒张末期容积、左心室收缩末期容积均较非MS组明显增加(P<0.05,P<0.01),左心室射血分数较非MS组明显减少(P<0.05)。30 d心性病死率,非MS组为1.7%,MS组为13.2%,差异有统计学意义(P<0.05)。结论:并有MS的AMI患者左心室重构和心功能损害更明显,30 d心性死亡危险增加。
Objective: To investigate the predictive value of metabolic syndrome (MS) on left ventricular remodeling, cardiac function and 30-day cardiac mortality in patients with acute myocardial infarction (AMI). Methods: Thirty-three AMI patients were divided into MS group (n = 53) and non-MS group (n = 60) according to NCEP-ATPⅢ standard. The left ventricular remodeling, cardiac function and 30-day cardiac mortality were compared between the two groups. Results: Left atrial diameter, left ventricular end diastolic dimension, left ventricular mass index, left ventricular end-diastolic volume and left ventricular end-systolic volume in MS group were significantly higher than those in non-MS group (P <0.05, P <0.01) Blood score was significantly lower than non-MS group (P <0.05). The 30-day cardiac death rate was 1.7% in the non-MS group and 13.2% in the MS group, with a significant difference (P <0.05). CONCLUSIONS: Left ventricular remodeling and cardiac dysfunction were more pronounced in AMI patients with MS, with an increased risk of 30-day cardiac death.
