Echocardiographic assessment of left cardiac structure and function in antiretroviral therapy (ART)‐naïve people living with HIV/AIDS

Abstract

Abstract Background Patients with human immunodeficiency virus (HIV) are at a significantly higher risk of cardiovascular disease (CVD) compared to HIV‐negative people. Left heart dysfunction is the most common cardiac complication in people living with HIV/acquired immune deficiency syndrome (PLWHA), and diastolic dysfunction is an important predictor of cardiovascular events. The aims of this study were (1) to detect changes in left cardiac structure and function in antiretroviral therapy (ART)‐naive PLWHA using echocardiography; and (2) to investigate the risk factors for the development of left ventricular diastolic dysfunction (LVDD) in ART‐naive PLWHA. Methods We retrospectively included 105 ART‐naïve PLWHA and included 90 healthy subjects as controls to compare the differences in left heart structure and function between the two groups. Univariate and multifactorial logistic regression were employed to explore the risk factors of the development of LVDD in ART‐naive PLWHA. Results The left ventricular end‐diastolic internal diameter (LVEDD), left ventricular mass index (LVMI), and left atrial volume index (LAVI) were significantly greater in PLWHA than in controls (p .05). Multifactorial logistic regression analysis showed that age, body mass index (BMI), and CD4+ count <200 cells/μL were independent risk factors for LVDD in ART‐naive PLWHA (OR = 1.781, 1.228, 3.683, p < .05). Conclusions Left ventricular systolic function did not differ between PLWHA and controls, and left ventricular diastolic function was lower in PLWHA than in controls. Age, BMI, and CD4+ count were independent factors affecting LVDD in ART‐naive PLWHA.
