Abstract:
It is well known that the mortality rate is very high in the patients with cerebrovascular disease (CVD). The most common cause of death in the ischemic CVD patients is myocardial infarction. The purpose of this study is to evaluate the diagnostic significance of myocardial perfusion SPECT for coronary artery disease (CAD) in ischemic CVD. We studied in 64 patients with transient ischemic attack and ischemic stroke diagnosed by means of the clinical history and brain CT and MRI. Electrocardiography, myocardial perfusion SPECT and coronary angiography were performed. We checked hypertension, diabetes, smoking, alcohol drinking and hyperlipidemia as the risk factors in ischemic CVD and CAD. The myocardial perfusion SPECT was abnormal in 37 out of 64 patients(57.8%) with ischemic CVD. There was a increasing tendency in the prevalence of myocardial perfusion abnormality in the elderly patients (more than 65 years old). The incidence of abnormal myocardial perfusion SPECT was not significantly different among TIA, lacunar infarction, minor infarction and major infarction. The long standing hypertension and hyperlipidemia were siginificant risk factors in the ischemic CVD and CAD as having the abnormal myocardial perfusion SPECT (p<0.05). There were not significantly different between resting EKG and myocardial perfusion SPECT results. Coronary artery stenosis was identified in 5 out of 7 patients receiving coronary arteriography. The results suggested that ischemic stroke is frequently associated with coronary artery disease. So myocardial perfusion SPECT as an active investigation for CAD in Ischemic CVD should be considered in order to optimal management.
