ST段压低型急性心肌梗塞的临床特征

目的　探讨ST段压低型急性心肌梗塞的临床特征。方法　比较 2 8例ST段压低型急性心肌梗塞 (AMI)与 170例非ST段压低型AMI(对照组 )的临床特点。结果　ST段压低组年龄大 [(6 7.8± 6 .2 )岁 (P <0 .0 5 ) ],有陈旧性心肌梗塞病史者较多 (P <0 .0 1) ,急性左心衰发生率高 (P <0 .0 5 ) ,心房纤颤发生率高 (P <0 .0 5 ) ,住院死亡率高 (P <0 .0 5 )。结论　ST段压低型AMI较非ST段压低型AMI患者年龄大 ,并发症发生率高 ,有OMI病史者多 ,预后差。

Clinical characteristics in patients with acut myocardial infarction with ST-segment depression on Electracardiogram

Objective To investigate clinical characteristics in patients with acut myocardial infarction with ST segment depression on Electracardiogram. Method To compare the clinical characteristic in 28 patient with acute myocardical infarction(AMI)with ST segment depression and in 170 cases without ST segment depression on initial electrodiogram(ECG). Results indicted that patients with ST segment de Pression were older(67.8±6.2, P <0.05), more likely to Have had old myocardiol infarction (46% vs 21%, P <0.05), and to have left ventricule failure (35.7% vs 20.5, P <0.05), than those without ST segment depression. Hospital mortality rate was signification higher in patient with ST segment depression than inthose without ST segment depression (25.0 vs 11.7, P <0.05). Conclusion patints with ST segment depression are likely to be older with a highpresence of previous myocardial infarction and to have higher complication and a poor prognosis.
