摘　　要：目的探讨冠状动脉(冠脉)造影正常的急性ST段抬高型心肌梗死(STEMI)患者的临床特点。方法选择456例STEMI患者,均行冠脉造影。比较冠脉造影正常与异常的ASTEMI患者的年龄、性别、既往病史等资料。结果456例STEMI患者中,共21例(4.6%)冠脉造影正常。31～40岁组冠脉造影正常者所占比例显著高于41～50岁组(χ2=19.025,P<0.01);41～50岁组又显著高于51～60岁组(χ2=5.375,P<0.05)。冠脉造影正常组和冠脉造影异常组患者的年龄,既往心绞痛、高血压病、糖尿病、高脂血症的发生率,吸烟史间差异均有统计学意义(P<0.05);而两组患者的性别及家族史间差异无统计学意义(P>0.05)。结论冠脉造影正常的STEMI患者年龄较小,多无心绞痛、高血压、糖尿病病史及血脂异常,且以大量吸烟者居多。Objective To investigate the morbidity rate and clinical characteristics of acute ST-segment elevation myocardial infarction （STEMI） with normal coronary angiograms （CAG）.Methods The CAG findings and related risk factors were analysed in 456 STEMI patients admitted to our hospital from August 2004 to August 2009.Results The patients with STEMI and normal CAG accounted for 4.6% （21/ 456） patients.The proportion of patients with normal CAG was significantly higher in 31～40-year-old group than in 41～50-year-old group （χ^2=19.025,P〈0.01）,and higher in 41～50-year-old group than in 51～60-year-old group （χ^2=5.375,P0.05）.There was significant difference in age,gender,and the incidence of angina pectoris,hypertentive disease,diabetes,hyperlipidemia and smoking history between groups normal CAG and abnormal （P0.05）,but there was not in family history （P〉0.05）.Conclusion Acute STEMI with normal CAG is more likely to occur in young smokers,most of whom have no history of angina pectoris,hypertensive,diabetes,or abnormal blood lipid.
