摘  要:目的:探讨无痛性心肌梗塞(PMI)的临床特点;核素心肌显像(ECT)与冠状动脉造影(CAG)对其诊断价值。方法:300例住院心肌梗塞患者,其中男196例,女104例。有胸痛者234例,无胸痛者66例。同时行 ECT 和冠脉造影检测,将结果进行对比分析。结果:(1)PMI 患者的女性比例、年龄、体重指数及糖尿病、高脂血症的发病率等指标均高于有胸痛组(P<0.05~<0.001);(2)临床症状:心衰、胃肠道症状、低血压或休克、脑卒中、异位疼痛等症状在两组间均存在显著差异(P<0.05~<0.001);(3)心肌酶学、TnT、ECG 在无痛组阳性率明显低于有痛组 (P<0.001);(4)ECT 与 CAG 两组间阳性率无差异;(5)PMI 组的误诊(27.27%)、漏诊(25:76)及住院死亡率明显高于有痛性心肌梗塞组(均为0%),P<0.01。结论:(1)ECT 是一种无创、方便、费用低的早期诊断 PMI 的重要方法;(2)动态观察心电图的变化是减少 PMI 误诊和漏诊的方便手段之一。Objective: To study (1) Clinical characteristic of painless myocardial infarction (PMI) : (2) The diagnosis value of single photon emission computed tomography (SPECT) and coronary angiography (CAG) on PMI. Metbods: A total of 300 acute myocardial infarction (AMI) patients were examined SPECT and CAG, among them 234 with chest pain (CPMI) and 66 without, then analyzed the check reports. Results: (1) The female, elder, higher BMI, incidence rate of diabetes and hyperlipemia in PMI were more than those of CPMI group (P〈0.05-〈0. 001); (2) There were significant difference between two groups in clinical symptoms (P〈0. 001 ), (3) The PMI group had lower positive finding rate in enzymology, ECG examination than those of CPMI group (P〈0. 001) ; (4) The positive finding rates in SPECT and CAG examination were no differences between two groups; (5) The misdiagnosis rate (27.27%) and miss diagnosis rate (25.76%) of PMI group were more than those of CPMI group (P〈0.01). Conclusion: (1) SPECT is a non-invasive, convenient, less cost and important examination method for earlier diagnosis of PMI; (2) ECG examination can reduce the misdiagnoses of PMI.
