不稳定型心绞痛的自然病史研究,其死亡率为1～60％,手术治疗后的死亡率为0～22％。作者认为上述统计数字相差悬殊的原因是由于病例选择标准不同。本文报道167例不稳定型心绞痛,其中11例因造影未发现冠状动脉显著损害而予以剔除。对上述病例除进行完整的临床检查及心电图、X线摄片、肌酸磷酸激酶、谷—草转氨酶、乳酸脱氢酶等测定外,对每个患者都作了冠状动脉造影和心室造影。心室造影所见分为两型:A型,正常或一侧心室壁轻至中度动力减弱;B型,心室壁运动损害较重。在随访期间每四个月复查一次。所有患者均未作冠
Study of natural history of unstable angina, the mortality rate was 1 to 60%, the mortality rate after surgery was 0 to 22%. The author believes that the above statistics vary greatly due to different case selection criteria. This article reports 167 cases of unstable angina pectoris, of which 11 cases were excluded due to coronary angiography found no significant damage. In addition to a complete clinical examination of these cases and ECG, X-ray, creatine phosphokinase, cereal grass aminotransferase, lactate dehydrogenase and other measurements, for each patient were made coronary angiography and ventriculography. Ventricle angiography seen divided into two types: A type, normal or mild side to moderate ventricular wall weakening; B type, ventricular wall injury heavier. Review every four months during follow-up. All patients did not crown
