Objective There is growing concern regarding cardiovascular disease in HIV‐infected individuals in developing countries such as Thailand. We evaluated the 10‐year risk of coronary heart disease (CHD) in a Thai HIV‐infected cohort using three cardiovascular risk equations, and assessed the level of agreement among their predictions. Methods We carried out a cross‐sectional analysis of data on 785 Thai subjects followed prospectively in the HIV Netherlands Australia Thailand Collaboration (HIV‐NAT) cohort study from 1996 to 2009. Cardiovascular risk factor history, along with relevant laboratory and clinical data, was collected at follow‐up clinic visits. Ten‐year risks of CHD were calculated using the Framingham, Ramathibodi–Electricity Generating Authority of Thailand (Rama‐EGAT) and Data Collection on Adverse Effects of Anti‐HIV Drugs (D:A:D) risk equations. Results The mean age of the patients was 41.0 years; 55% of the subjects were male. The mean duration of antiretroviral therapy was 7.7 years. The prevalence of cardiovascular risk factors was low, with the most common risk factor being low high‐density lipoprotein (HDL) (36.3%). The prevalence of high cardiovascular risk scores (defined as 10‐year risk of CHD≥10%) was also low: 9.9, 2.1 and 0.8%, by the Framingham, Rama‐EGAT and D:A:D scoring systems, respectively. Only eight subjects (1.0%) had a history of CHD. Bland–Altman plots showed that the Framingham equation predicted a higher risk of CVD compared with the Rama‐EGAT and D:A:D equations, which agreed relatively well. Conclusion The predicted cardiovascular risk in this HIV‐infected Thai cohort was relatively low. The agreement among the Rama‐EGAT and D:A:D risk scores suggests that both equations may be appropriate estimators of cardiovascular risk in this population.
