摘要
目的 通过对冠状动脉 (冠脉 )造影正常的急性心肌梗死 (MINC)患者的随访 ,探讨其临床预后 ,并分析发病危险因素。方法 1987至 2 0 0 1年北京大学第一医院 4 0例 (A组 )首次急性心肌梗死后冠脉造影正常 (冠脉造影狭窄程度小于 2 0 % )患者。同时随访了 12 9例 (B组 )年龄、性别、梗死部位与A组相匹配的冠脉造影严重狭窄 (梗死相关血管狭窄程度 >5 0 % )的急性心肌梗死患者 ,比较分析两组患者急性期、远期预后及发病危险因素。结果 高血压史、危险因素个数、梗死后心绞痛发生率A组明显低于B组。住院期间LVEFA组明显高于B组。两组患者平均随访时间相似 (6 7± 4 0比 6 8± 34月 )。复合心血管事件发生率A组明显少于B组。结论 MINC患者急性期、远期预后明显好于MICS患者 。
Objective To evaluate the clinical outcome of patients who suffered from acute myocardial infarction with angiographically normal coronary arteries (MINC) Methods Forty patients (mean age: 52 6±12 2 years; range: 30-75 years) admitted with acute myocardial infarction had normal coronary arteries after AMI, defined by normal or insignificant <20% stenosis in one vessel only (Group A) The Group A patients were matched for age, sex with a group (Group B) of 129 patients with coronary artery stenosis (>50% diameter stenosis) The risk factors, clinical data, ventricular functions and the long term outcomes were compared between Group A and Group B Results Hypertension and previous angina were more frequent in Group B Patients in Group A had a lower number of risk factors associated with them than patients in Group B LVEF during hospital was higher in Group A than in Group B The mean follow up period was 67±40 months in Group A and 68±34 months in Group B Incidencs of rehospitalization, repeat intervention therapies, heart failures, and total heart events were fewer in Group A than in Group B Conclusion These data suggest a favorable long term prognosis and fewer risk factors in patients who suffered from acute myocardial infarction with normal or nearly normal coronary arteriogram
