平均24.9(18～39)岁的10(男7、女3)例急性心肌炎患者发病不久具有急性心肌梗塞的表现。各例均有急性病毒感染的症状。7例具有急性病毒感染的实验室依据:病毒学检查阳性4例(4/10),焦磷酸盐扫描广泛性异常3例(3/6)和局限性异常2例(2/6),心内膜活检阳性1例(1/3)。急性心肌梗塞的表现有:胸痛9例,心电图相应表现10例,血清磷酸肌酸水平增高10例,MB 组分阳性8例和局部室壁活动异常8例。急性期间,6例左室喷血分数<55%,5例室性异位活动,4例束支传导阻滞,3例一过性交界处逸搏性心律,3例充血性心力衰竭。平均随访5.8(1～14)个月,死亡1例。随访期间,5例(5/6)运动试验阴性,3例(3/3)冠状动脉造影未见异常,5
An average of 24.9 (18 to 39) years of age 10 (male 7, female 3) cases of acute myocarditis in patients with onset of acute myocardial infarction performance. Each case has the symptoms of acute viral infection. Seven laboratory-based studies with acute viral infection were based on 4 virological tests (4/10), 3 (3/6) cases of extensive pyrophosphate scans and 2 (2/6) cases of localized abnormalities Intimal biopsy was positive in 1 case (1/3). The manifestations of acute myocardial infarction were chest pain in 9 cases, electrocardiogram in 10 cases, elevated serum creatine phosphate in 10 cases, MB in 8 cases and abnormal local wall activity in 8 cases. In the acute period, 6 patients had a left ventricular ejection fraction of 55%, 5 patients had ventricular ectopic activity, 4 had bundle branch block, 3 had a transient borderline escape stroke and 3 had congestive heart failure. The average follow-up 5.8 (1 ~ 14) months, 1 patient died. During follow-up, 5 (5/6) exercise tests were negative, 3 (3/3) coronary angiography showed no abnormality, and 5
