目的 探讨急性心肌梗死 (AMI)患者血清心肌肌钙蛋白I(cTnI)水平与近期预后的关系。方法 测定 5 1例AMI患者的血清cTnI,根据cTnI水平分为二组 ,观察住院期间心力衰竭、缺血性胸痛、心脏性死亡的发生率 ,测定左心室射血分数 (LVEF) ,分析cTnI水平与它们的关系。结果 在 5 1例AMI患者中 ,cTnI较高组 2 9例 ,较低组 2 2例 ,住院期间发生心力衰竭为 4 1 38%相对于 9 0 9% ,(P <0 0 1) ,缺血性胸痛为 4 4 83%相对于 18 18% ,(P <0 0 5 ) ,心脏性死亡为 3例相对于 0例 ,LVEF为 4 8%± 12 %相对于 5 8%± 12 % ,(P <0 0 5 ) ,存在显著差异。结论 血清cTnI是AMI患者住院期间预后的独立预测因子。
Objective To investigate the relationship between serum cardiac troponin I (cTnI) and the prognosis in patients with acute myocardial infarction (AMI). Methods The serum levels of cTnI in 51 patients with acute myocardial infarction (AMI) were determined. The levels of cTnI were divided into two groups according to the level of cTnI. The incidence of heart failure, ischemic chest pain and cardiac death during hospitalization was observed. Left ventricular ejection fraction (LVEF) Relationship with them. Results Among the 51 AMI patients, 29 were higher in the cTnI group and 22 in the lower group. Heart failure during hospitalization was 41 38% to 90% (P <0.01) The incidence of bloody chest pain was 44.33% vs 18.18% (P <0.05), cardiac death was 3 cases versus 0 case, LVEF was 48% ± 12% vs. 58% ± 12% (P <0 05), there are significant differences. Conclusions Serum cTnI is an independent predictor of prognosis during AMI in hospital.
