45岁以下的妇女心肌梗死罕见,在住院的心肌梗死患者中不到1%。1975年在英格兰和威尔斯,年龄30～44岁妇女因冠心病死亡者仅258例;同年龄男性则有1,497例。 Morris等在分析24名40岁以下妇女患心肌梗死的情况时,发现4例非动脉粥样硬化性心脏病。2例由持续性冠状动脉栓子所致;1例系暴发型系统性红斑狼疮引起的冠状血管炎;另1例为冠状动脉夹层动脉瘤(本病见于年轻妇女,特别是孕妇)。尽管高胆固醇血症妇女可发生心脏病,但其危险性似比男性低。与年轻男性冠心病相反,年轻妇女的心肌梗死患者,Ⅳ型高胆固醇血症并不常见。也有人
Women under the age of 45 have a rare myocardial infarction, less than 1% of hospitalized patients with myocardial infarction. In England and Wales in 1975, only 258 women aged 30-44 died of coronary heart disease; 1,497 men were at the same age. Morris and colleagues analyzed four non-atherosclerotic heart disease in 24 women under 40 years of age with myocardial infarction. 2 were caused by persistent coronary emboli; 1 was fulminate systemic lupus erythematosus-induced coronary vasculitis; and 1 was coronary artery dissection aneurysm (this disease occurs in young women, especially pregnant women). Although hypercholesterolemic women can develop heart disease, their risk is lower than that of men. In contrast to young men with coronary heart disease, IV hypercholesterolemia is uncommon in young women with myocardial infarction. There are also people
