Objective Cardiovascular involvement causes significant morbidity and mortality among patients with human immunodeficiency virus ( HIV ) infection. Since the introduction of highly active antiretroviral treatment ( HAART ), subtle changes in left ventricular ( LV ) function, which may be clinically silent, have become more pronounced in HIV patients. Echocardiographic strain imaging ( SI ) may detect subclinical myocardial dysfunction at an earlier stage compared with conventional echocardiography. The aim of this study was to evaluate tissue Doppler–derived LV strain and strain rate (SR) along with conventional measures of LV function in asymptomatic, stable adult HIV patients on HAART . Methods Twenty‐one patients with HIV infection (mean age: 37.8 ± 11.9 years, 11 males) who had no cardiovascular complaints and 27 healthy volunteers (mean age: 40.9 ± 5.8 years, 14 males) were enrolled. Traditional parameters including LV ejection fraction ( EF ) were measured along with tissue velocity imaging ( TVI ) and tissue Doppler SI parameters using transthoracic echocardiography. Results The mean duration of HIV infection was 30.8 ± 25.1 (3–120) months. The mean LVEF in HIV group was within normal limits but lower than controls (64.5% ± 10.2% vs. 72.2% ± 6.4%, P = 0.003). There were no differences in other major traditional measures, as well as TVI parameters between groups. LV systolic strain and SR parameters were impaired indicating subtle LV systolic dysfunction in HIV group. No difference in diastolic function was observed between groups. Conclusion Left ventricular systolic strain parameters may be utilized to demonstrate subtle LV systolic dysfunction in asymptomatic HIV patients.
