简要总结
The present study aims to evaluate the cardiovascular changes in long-term virologically controlled HIV patients. All the participants have been treated and have been undetected for at least five years. Vascular ultrasound and echo will be carried out at 0, 24, 48 and 96 weeks of follow-up.
详细描述
Previous studies have indicated that chronic HIV infection has resulted the diastolic cardiac dysfunction. In this study, 500 long-term virologically controlled HIV-infected individuals will be followed for two years, and evaluated at 0, 24, 48 and 96 weeks of follow-up. At each visiting point, ultrasound evaluation of carotid and vertebral arteries and the heart function will be carried out and compared.

结局指标
主要结局
Number of Participants with abnormal brachial-ankle arteries measured by ultrasound at 48 weeks
时间窗: 48 weeks
The ankle-brachial index (ABI) and pulse wave velocity (PWV) including right and left brachial-ankle are aceessed through ultrasound. The measured value will be documented and evaluated for abnormality.
Number of Participants with abnormal brachial-ankle arteries measured by ultrasound at 96 weeks
时间窗: 96 weeks
The ankle-brachial index (ABI) and pulse wave velocity (PWV) including right and left brachial-ankle are aceessed through ultrasound. The measured value will be documented and evaluated for abnormality.
Number of Participants with abnormal echocardiogram results at 48 weeks
时间窗: 48 weeks
Echocardiogram indicators include left ventricular end-diastolic diameter, left ventricular end-systolic diameter, left ventricular fractional shortening (LVFS), ejection fraction (EF), E/A ratio, E-wave deceleration time (EDT), isovolumetric relaxation time (IVRT), tricuspid regurgitation velocity (TRV), Pulmonary artery systolic pressure, Interventricular septal (IVS ) thickness, left ventricular posterior wall thickness, the present of valve abnormalities/ myocardial ischemia/ pericardial effusion. The measured value will be documented and evaluated for abnormality.
