无痛性心肌梗死33例分析

The analysis of 33 patients with painless myocardial infarction

目的探讨无痛性心肌梗死患者的临床特点。方法回顾性分析无痛性心肌梗死（A组）33例临床资料，并与同期诊治的典型急性心肌梗死（B组）进行比较。结果两组年龄（χ^2=5．72，P〈0．05）、就诊时间（t=30．98，P〈0．05）及预后（χ^2=32．17，P〈0．05）差异均有统计学意义；性别（χ^2=1．63，P〉0．05）、既往史（χ^2=4．88，P〉0．05）及就诊至确诊的时间（t=1．44，P〉0．05）差异均无统计学意义。结论无痛性心肌梗死患者临床表现多样且年龄大、就诊迟、预后差。

Objective To investigate the clinical feature of painless myocardial infarction. Methods To retrospectively study the clinical data of 33 patients who suffered from painless myocardial infarction, and compare with that of typical acute myocardial infarction patients. Results There wasn＇ t significant difference in gender（ χ^2 = 1.63, P 〉 0. 05 ） and past history （χ^2 = 4. 88, P 〉 0. 05 ）, the time from visit to diagnosis （ t = 1.44, P 〉 0. 05 ） between painless myocardial infarction patients and typical acute myocardial infarction patients. But there was significant difference in the age （ χ^2 = 5.72, P 〈 0. 05 ）, the visit time （ t = 30.98, P 〈 0.05 ）, and the prognosis （ χ^2 = 32. 17, P 〈 0. 05）. Conclusion Patients with painless myocardial infarction have diverse clinical manifestations. They are usually aged and delayed in seeking treatment and at last have a bad prognosis.
