非Q波型梗塞诊断标准为:1.典型症状.2.血清CK峰值大于2倍正常上限,3.特续性ST段和T渡转化,但无新的异常Q渡。共93例符合非Q波型梗塞,又分3个亚型:Ⅰ型,开始时ST段下降,Ⅱ型,开始时ST段抬高,Ⅲ型,开始时T波改变但无ST段移位。对年龄≤65岁的存活者,于急性心肌梗塞(AMI)后4周左右作冠脉造影。 AMI12小时内的心电图记录中,Ⅰ型49例,Ⅱ型35例,Ⅲ型9例。平均年龄相似,分别为63.4±10.2、58.9±9.1和83.8±9.1岁。男性分别占76％、80％和78％。Ⅰ型患者中泵衰竭人数(Killip Ⅱ-Ⅳ级43％)多于另外二型(P<0.01)。51例作了冠脉造影,结果Ⅰ型中多支(2或3支)血管病变人数多于Ⅱ型或Ⅲ型,分别为92％,68％和60％(P<0.05)。80％Ⅰ型病人为3支血管病变。CK峰值无明显差别。住院期死亡13例,其中Ⅰ型12例,Ⅱ
Non-Q-wave infarction diagnostic criteria are: 1. Typical symptoms .2. Serum CK peak greater than 2 times the upper limit of normal, 3. Special ST segment and T transition, but no new abnormal Q crossing. A total of 93 patients with non-Q-wave infarction, and sub-sub-three subtypes: type Ⅰ, ST segment decreased at the beginning, type Ⅱ, ST segment elevation at the beginning, type Ⅲ, beginning with T wave changes without ST segment shift . Coronary angiography was performed at 4 weeks after acute myocardial infarction (AMI) for survivors ≤65 years of age. AMI 12 hours ECG records, 49 cases of type Ⅰ, 35 cases of type Ⅱ, 9 cases of type Ⅲ. The mean age was similar, 63.4 ± 10.2, 58.9 ± 9.1, and 83.8 ± 9.1 years, respectively. Men make up 76%, 80% and 78% respectively. Type I patients had more pump failure (43% Killip class II-IV) than the other two (P <0.01). Fifty-one patients underwent coronary angiography. The results showed that the number of multi-branch (2 or 3) vessels in type I was more than that in type II or III (92%, 68% and 60%, respectively) (P <0.05). 80% of type I patients with 3 vascular lesions. CK peak no significant difference. In-hospital deaths in 13 cases, of which 12 cases of type Ⅰ, Ⅱ
