| 目的 观察急性心肌梗死溶栓治疗后3h、24h心电图ST段回落程度和出院前超声心动图心功能指标,探讨24h ST段回落程度的预后意义。方法 123例首次急性心肌梗死近期(3周)存活病例,测量急性期心电图ST段抬高最明显的导联在溶栓治疗开始后3h、24h回落程度(%),各分为ST段回落≥50%组和＜50%组,比较各组在第三周超声心动图测量的心功能参数(t检验),并以心功能参数为因变量、以急性期与再灌注有关的数据为自变量做多元逐步回归分析。结果 3h、24h ST段回落≥50%组心功能参数LVEF、LVFS分别明显高于ST段回落＜50%组(P＜0.001)。逐步回归分析提示:3h和24h ST段回落程度是心功能参数的独立预报因子。结论 溶栓3h和24h ST段回落是重要的近期预后指标;24h ST段回落有特殊的心功能预后意义;3~24h之间ST段继续回落可能仍有积极的意义。 |

| Objective To observe ST segment recovery at 3 hours, 24 hours after thrombolysis in patients with AMI and cardiac function parameters measured by UCG before dischargement, and to evaluate the prognostic significance of ST segment recovery after thrombolysis. Methods We studied 123 patients with AMI, measured the ST recovery in the maximum elevation lead at 3 hours, 24 hours after thrombolysis respectively. The patients were classified into group A (ST resolution≥50％) and group B (ST resolution＜50％) at 3 hours and 24 hours after thrombolysis respectively, and cardiac function parameters were compared among different groups. Results At 3 hours and 24 hours, cardiac function parameters (LVEF, LVFS) of group A were higher than which of group B (P<0.001). It was also indicated by multiple regression (stepwise) that both 3 and 24 hours' ST recovery degree were independent predict factors of prognosis.Conclusion ST recovery at 3 hours and 24 hours is important prognostic predictor, especially at 24 hours; ST recovery from 3 to 24 hours is of great significance for better prognosis. |
