title: Is estimated cardiovascular risk higher in HIV-infected patients than in the general population?
abstract: Cardiovascular disease (CVD) is an increasing concern for human immunodeficiency virus (HIV)-infected patients, and risk assessment is recommended in routine HIV care. The absolute cardiovascular risk in an individual is determined by several factors, and various algorithms may be applied. To date, few comparisons of HIV patients with persons of the same age from the general population have been conducted. We hypothesized that the calculated risk of CVD may be increased in HIV patients. The probability for acute coronary events within 10 y (Framingham Risk Score) and the probability for fatal cardiovascular disease (SCORE algorithm) were assessed in 403 consecutive HIV-positive subjects free from overt cardiovascular disease, as well as in 96 age- and gender-matched control subjects drawn from the general population living in the same geographical area. The average 10-y risk for acute coronary events (Framingham Risk Score) was 7.0%+/-5% in HIV subjects and 6.3%+/-5% in the control group (p =0.32). The 10-y estimated risk for cardiovascular mortality (SCORE algorithm) was 1.23%+/-2.3% and 0.83%+/-0.9%, respectively (p =0.01). The main contributor to the increased CVD risk was the high proportion of smokers, but not an increase in cholesterol level. In conclusion, a limited increase in estimated risk of CVD was found in HIV-infected patients compared to the general population. In HIV-infected individuals other factors of less value in the general population and not included in any cardiovascular algorithm might be important. In our patients intervention to modify traditional risk factors should be addressed primarily towards modifying smoking habits.
