Prevalence and patterns of echocardiographic abnormalities among people living with HIV on anti-retroviral therapy in Kumasi, Ghana

BackgroundEchocardiography can be used to screen, confirm, and assist in the management of some cardiovascular diseases in people living with human immunodeficiency virus (HIV) (PLWH). Thus, complications from subclinical cardiovascular conditions or more apparent conditions, such as massive pericardial effusion with tamponade, can be promptly identified and managed to minimize cardiovascular morbidity and mortality associated with HIV infection. Since the introduction of antiretroviral therapy (ART) in Ghana approximately two decades ago, studies on the prevalence and patterns of echocardiographic abnormalities among PLWH on ART have been limited. This study was designed to assess the prevalence and patterns of echocardiographic abnormalities among PLWH on ART.MethodsThis was a cross-sectional study. PLWH on ART (cases) attending the HIV clinic at Komfo Anokye Teaching Hospital (KATH) and HIV-negative blood donors (controls) were consecutively recruited and enrolled in this study. The interviews were performed via a standardized questionnaire. After a clinical examination was performed, all patients underwent two-dimensional (2D) and Doppler transthoracic echocardiograms. The prevalence and patterns of echocardiographic abnormalities were characterized.ResultsThere were 117 patients in each arm of the study. There were more females than males among both the cases (92 (78.6%) and controls (80 (68.4%)); however, the sex distribution was similar between the two groups (p = 0.075). For clinical characteristics such as age, weight, height and blood pressure, there were no statistically significant differences between the cases and controls. Echocardiographic abnormalities were more frequently observed and demonstrated a statistically significant difference between cases and controls, with an overall prevalence of 35.0% among cases and 19.7% among controls (p = 0.008). The echocardiographic abnormalities that demonstrated significant differences between the cases and controls were left ventricular (LV) diastolic dysfunction (28.2% versus 8.6%; p = 0.000) and LV hypertrophy (7% versus 0.9%; p = 0.017).ConclusionNearly 1 in 3 PLWH on ART had an echocardiographic abnormality in this Ghanaian study. Echocardiograms are recommended as helpful screening modalities for diagnosing cardiac abnormalities among PLWH on ART.
