对２１９例缺血性脑卒中与心功能减退间关系进行了年龄分组的对照比较，结果发现，心功能减退与缺血性脑卒中的关系极为密切。冠心病，房颤、高血压性心脏病和瓣膜病变的发生率是随着年龄的逐渐增长而升高（Ｐ＜０．０５～０．０１），且导致缺血性脑卒中的发病率也不断增加。在老年人房颤既是缺血性脑卒中的独立危险因素，又可与其它心脏疾病伴随。冠心病是产生房颤的最常见病因 219 cases of ischemic stroke and hypothyroidism were compared between age groups, the results showed that the relationship between hypothyroidism and ischemic stroke is extremely close. The incidence of coronary heart disease, atrial fibrillation, hypertensive heart disease and valvular disease increased with age (P <0.05 ~ 0.01), and the incidence of ischemic stroke was also Increasing. Atrial fibrillation in the elderly is not only an independent risk factor for ischemic stroke, but also with other heart disease. Coronary heart disease is the most common cause of atrial fibrillation
