A long-term follow-up study of 21 patients with 24 attacks of acute non-Q-wave myocardial infarction admitted to Beijing Hospital was carried out and clinicopathological correlation was made in 9 by autopsy. The results revealed that in patients with non-Q-wave myocardial infarction the mortality rate in acute stage was 14.3%, the 2-year aggregate mortality rate 33.3% and the rate of reinfarction 38%, while in patients with Q-wave myocardial infarction admitted in the same period the rate was 18.9%, 26.2% and 17.3%, respectively. It was thus shown that non-Q-wave myocardial infarction was an unstable condition. Although its prognosis in the acute stage was slightly better than that of Q-wave myocardial infarction, yet its outcome in the long run was poorer. Clinicopathological correlation showed that the diagnostic criteria for acute non-Q-wave myocardial infarction used at present are practical and a negative serum enzyme does not preclude the possibility of this disease.
对北京医院收治的21例发生24次急性非Q波心肌梗死发作的患者进行了一项长期随访研究，并对其中9例进行了尸检以进行临床病理相关性分析。结果显示，非Q波心肌梗死患者急性期死亡率为14.3%，2年总死亡率为33.3%，再梗死率为38%，而同期收治的Q波心肌梗死患者的相应比率分别为18.9%、26.2%和17.3%。由此表明，非Q波心肌梗死病情不稳定。虽然其急性期预后略优于Q波心肌梗死，但长期预后较差。临床病理相关性分析表明，目前使用的急性非Q波心肌梗死诊断标准是实用的，血清酶阴性并不能排除该病的可能性。
