Factors influencing left ventricular diastolic dysfunction on echocardiography of people living with HIV in Kunming, China

Background: The widespread use of antiretroviral therapy has prolonged the survival of people living with HIV (PLWH). Among these patients, co-existing cardiovascular diseases, particularly left ventricular diastolic dysfunction (LVDD), are receiving increasing attention.

Methods: We recruited 386 patients in the PLWH group and 386 sex- and age (± 3 years)-matched individuals in the HIV-negative group, and used logistic regression to determine the risk factors of LVDD.

Results: Compared to the HIV-negative group, PLWH had a significantly higher prevalence of smoking (p < .001), alcohol consumption (p < .001), hypertension (p = .002), diabetes (p = .020), and hyperlipidemia (p < .001) and a lower prevalence of body mass index (BMI) ≥ 24.0 kg/m² (p < .001). The prevalence of LVDD on echocardiography was significantly higher in PLWH than in the HIV-negative group (25.9% vs 16.1%, p = .001). The multivariate analysis showed that non-youth (OR = 8.666; 95%CI = 4.310-17.459; p < .001), BMI ≥ 24.0 kg/m² (OR = 1.992; 95% CI = 1.007-3.939; p = .048), hypertension (OR = 1.888; 95% CI = 1.044-3.415; p = .036), hyperlipidemia (OR = 1.911; 95% CI = 1.068-3.418; p = .029), and HIV infection (OR = 2.003; 95%CI = 1.341-2.992; p = .001) were risk factors for LVDD.

Conclusion: The rate of echocardiographic abnormalities was higher in PLWH. LVDD was associated with non-youth, BMI ≥ 24.0 kg/m², hypertension, hyperlipidemia, and living with HIV.
