Background: One of the clinical manifestations of Human Immunodeficiency Virus (HIV) infected patients is cardiovascular disorder. The aim of this study was to evaluate the prevalence of cardiovascular disorders in HIV infected patients for the beginning treatment of these patients and reducing mortality and morbidity in these patients.
Methods: This cross-sectional study was performed on 134 HIV infected patients who referred to Imam Khomeini hospital, Tehran University of Medical sciences, Tehran Iran during years 2007-2008. Demographic characteristics, history of smoking and opium addiction, antiretroviral therapy, class of drugs and duration of consumption were recorded. After completion of physical examination, electrocardiography and echocardiography studies were done.
Results: In this study 98(73.1%) patients were male. The mean age of the patients was 36.5±10.3 years. The mean of the CD4 number were 296±181. Injection drug users were 54.4% of the study patients. Cardiovascular disorders were found in 84(62.7%) patients. Among patients with heart diseases, 75% were male. The most Electrocardiographic change was the axis deviation of the heart found in 32(23.7%) patients. Pericardial effusion and LVEF<50% were noted in 7(5.2%) and 23(17.2%) patients respectively. The involvement of the mitral valve in 59(44%), tricuspid valve in 21(15.7%) and aortic valve in 6(4.5%) patients were noted. Myocardial dysfunctions existed in 10(7.4%) patients.
Conclusions: Our results showed a high prevalence of cardiovascular disorder in HIV infected patients. We recommend the evaluation of the cardiovascular system in all HIV infected patients even if they are symptom free.
