Estimated risk of cardiovascular disease among the HIV-positive patients aged 40 years or older in Taiwan.

Abstract

Cardiovascular disease (CVD) is an emerging cause of morbidity and mortality among HIV-positive patients receiving successful combination antiretroviral therapy, but their CVD risk has been rarely investigated in Asia-Pacific region. We aimed to assess the CVD risk of HIV-positive Taiwanese outpatients. We did cross-sectional questionnaire interviews to collect information of HIV-positive Taiwanese patients aged 40-79at the HIV clinics of a medical center from 1 March to 31 August, 2017. The Framingham Risk Score (FRS), Atherosclerotic Cardiovascular Disease (ASCVD) risk score and Data-Collection on Adverse effects of Anti-HIV Drugs (D:A:D) risk score were used to estimate their CVD risk. Of the screened 1251 patients, 1006 (80.4%) with complete data to assess their CVD risk were included for analyses. The prevalence of patients aged 40-75 and with a high CVD risk was 30.6% by FRS, 3.7% by D:A:D (R) risk score, and 22.2% by ASCVD risk score. In multiple logistic regression, older age, current smoking, higher systolic blood pressure, and higher triglyceride and fasting glucose levels were independently associated with the ASCVD risk score ≥7.5%. If current smokers aged 55-59 had stopped smoking, the proportions of them with a 10-year CVD risk of ≥10% by FRS and ≥7.5% by ASCVD risk score would have decreased by 35.3% and 20.0%, respectively. Higher CVD risk estimates among HIV-positive Taiwanese aged 40-75 were associated with an older age, current smoking, higher systolic blood pressure, hypertriglyceridemia, and hyperglycemia. Smoking cessation could potentially lead to significant decreases of CVD risk.
