随着CT和MRI这些新诊断方法的应用,发现老年人无症状性颅内形态学改变极为普遍。为了调查有动脉粥样硬化并发症的高危病人中隐型脑梗塞的发生率,作者对疑有缺血性心脏病者在冠状动脉造影后做头部CT和颈动脉超声。评估了隐型脑梗塞与冠状动脉疾病的严重度、颈动脉粥样化改变程度和脑血管病危险因素间的关系。对象与方法本研究以92例缺血性心脏病患者为研究对象,男性63例,女性29例。排除潜在脑血管病的心源性因素,如瓣膜性疾病、心源性栓塞、心律失常以及有症状的卒中,所有病人在做冠状动
With the application of these new diagnostic methods, such as CT and MRI, it is found that asymptomatic intracranial morphological changes in the elderly are extremely common. To investigate the incidence of occult cerebral infarction in high-risk patients with atherosclerotic complications, the authors performed head CT and carotid ultrasound after coronary angiography in patients with suspected ischemic heart disease. The relationship between the severity of occlusive cerebral infarction and coronary artery disease, the degree of change in carotid atherosclerosis and the risk factors of cerebrovascular disease was evaluated. Subjects and Methods In this study, 92 patients with ischemic heart disease were studied, 63 males and 29 females. Cardiogenic factors that exclude underlying cerebrovascular disease, such as valvular disease, cardioembolism, arrhythmia, and symptomatic stroke, all patients undergoing coronary
