Abstract:
Objective To evaluate the significance of coronary calcification and stenosis in elderly hypertensive patients by 16-row multi-sliced computed tomography (MSCT) and its association with peripheral arterial atherosclerosis and other target organ damages. Methods Sixty-four patients with hypertension (n=50) 76.1?6.5 years and normotensions (n=14) 73.4?6.8 years were enrolled. All patients underwent coronary calcification scan by MSCT and the coronary calcification score(CCS) was calculated as AJ130 and Volume. Fourty-four patients in the hypertensive group were subjected to MSCT enhanced scan for evaluation of coronary stenosis. Intima media thickness (IMT), atherosclerotic and calcified plaques in carotid and femoral arteries and ankle-brachial index (ABI) carotid and femoral arteries were measured by echosonography and echocardiography; Fasting plasma blood glucose, blood lipid series, insulin, HOMA-IR, hsCRP and morning urine albumin were determined. Results (1) Both AJ130 and Volume of left anterior descending artery(LAD), left circumflex artery(LCX) and the total calcification score were higher in the hypertensive group than those in the control group (P
