摘要
目的 探讨 ５０ 岁以下心肌梗死（ｍ ｙｏｃａｒｄｉａｌ ｉｎｆａｒｃｔｉｏｎ， Ｍ Ｉ）患者冠脉病变特点及危险因素对其发病率和死亡率的关系。方法 采用年龄分组：组 １ 年龄＜ ５０ 岁 ３９ 例；组 ２ 年龄＞ ６０ 岁 ４０ 例作为对照。比较 ２ 组性别、冠心病危险因素、病变特点、病死率关系。结果 ５０ 岁以下 Ｍ Ｉ病人前壁、前间壁部位梗死率（５１％ ）高于组 ２（３２５％ ），２ 组差异有显著性（ Ｐ ＜ ００５）。男性发病率明显高于女性（ Ｐ ＜ ０００５）。组 １ 中有冠心病家族史明显高于组 ２（ Ｐ ＜ ０００５）。随访：组 １：３％ 死亡；组 ２：２０％ 死亡。结论 ５０ 岁以下 Ｍ Ｉ病变特点以前壁、前间壁部位为主，男性发病率明显高于女性，病死率明显低于对照组，预后较高龄患者好。
Objective To study the clinical characteristics, fatality and different risk factors in younger AMI patients.Methods Patients were divided into two groups: 39 cases with ages below 50 in Group Ⅰ and 40 cases with ages above 60 in Group Ⅱ.Then their changes in ECG, risk factors and fatalities,etc.were compared.Results In younger adults, myocardial infarctions occurring on anterior and anteroseptal wall were much more, about 51% against 32.5% in Group Ⅱ (P<0.05).Higher incidence was found in man than in woman.Patients with family history of CAD in Group I were much more common than that in Group Ⅱ (P<0.005).Conclusion MI occurrs more on anterior and anteroseptal walls in younger adults.MI is more common in man than in woman.Prognosis is rather good in Group Ⅰ,but precaution should be taken in children with family history of CAD.
