Background: The prevalence of cardiovascular diseases (CVD) in HIV-infected patients increases with aging and duration of the disease. Hypertension, high cholesterol level obesity, diabetes, tobacco exposure, and use of alcohol are among the traditional risk factors that contribute to CVD.
Aim: The aim of the study was to determinate the incidence of hypertension, lipid disturbances, and CVD risk in dependence on clinical, viral, and biochemical factors.
Methods: A total of 417 HIV-infected Caucasian adult patients from the four clinical centres in Poland were enrolled and analysed on the basis of available medical data from the years 2013-2015.
Results: Hypertension was diagnosed in 28% of all patients and in the age ranges: < 40 years, 41-60 years and > 60 years in 18%, 43%, and 53%, respectively. The percentage of optimal, normal, and high normal blood pressure was: 28%, 14%, and 30%, respectively. Hypertension grade 1, 2, and 3 was observed in 58%, 35%, and 7% of patients, respectively. Factors associated with hypertension were: increasing age, male sex, increased body mass index, hypercholesterolaemia, hypo-high density lipoprotein (HDL), hypertriglyceridaemia and duration of HIV infection more than 10 years. Hypercholesterolaemia, suboptimal level of HDL, elevated low-density lipoprotein, and hypertriglyceridaemia were observed in 37%, 20.5%, 31%, and 52%, respectively. Hypertriglyceridaemia was associated with protease inhibitor-based highly active antiretroviral therapy. HCV infection was negatively associated with hypercholesterolaemia. Cigarette smoking was reported in 55% of cases.
Conclusions: Incidence of hypertension in particular age groups of HIV infected people is higher than in the general Polish population. Hypertension is influenced by traditional risk factors and duration of HIV infection but not antiretroviral treatment. HIV/HCV coinfection appears to be protective against hypercholesterolaemia.
