无痛性心肌梗死临床特征的观察

Observation of clinical characteric of no chest pain myocardial infarction

目的探讨无痛性心肌梗死(NCPMI)患者的临床特征。方法将146例AMI患者根据发病时有无胸痛主诉分成无痛组(NCPMI组)和疼痛组(CPMI组)。回顾性分析两组的临床特征,并行对比分析。结果NCPMI组患者发病年龄高于CPMI组(69.0±9.7岁比63.0±7.4岁,P<0.01),NPCMI组中女性发病率明显高于男性(32:20)。NCPMI并多伴糖尿病(28.1%),(CPMI组为19.9)。NCPMI组来院就诊时间明显长于CPMI组(9.4±3.2比4.2±1.1,P<0.01),住院病死率NCPMI组(12.3%)高于CPMI组(6.2%)(P<0.001)。结论急性心肌梗死患者发病前可无胸痛症状,并以年龄偏高者多见,多伴有糖尿病、预后较有胸痛症状者差。

To explore the clinical characteric of the patients with no chest pain myocardical infarction (NCPMI). Depended on having chest or not when it inovased, 146 case patients with acute myocardial infardial (AMI) were divided into NCPMI group and CPMI ( chest pain myocardial infarction) group. Retrospective studied the clinical characteric of the patients of the two groups by compared with each other. The patients of NCPMI group were elder than CPMI group′s (69.0±9.7 vs 63.0±7.4) (P <0.01). In NCPMI group, the female were much more than the male on morbidity (32:20). The patients of NCPMI group were more likely to be accompany with diabetes mellitus (28.1%) (while CPMI group was 19.9%). The time NCPMI group had been in hospital was longer than CPMI group′s (9.4±3.2 vs 4.2±1.1) (P <0.01). The case fatality rate during hospitalization of NCPMI group was higher contrast to CPMI group (12.3% vs 6.2%) (P <0.001). [Conclusion] The patients of AMI may has no chest pain symptom when it inovased. The elder are likely to get AMI, and more likely to be accompany with diabetes mellitus. The prognosis is worse than that having chest pain.
