ABSTRACT
BACKGROUND: HIV and HCV have each been linked with cardiac dysfunction. Studies of HIV have often lacked appropriate controls and primarily involved men, while data for HCV are sparse.
METHODS: We performed repeat echocardiography over a median interval of 12 years in participants from the Women’s Interagency HIV Study in order to evaluate the relationships of HIV and HCV with incident left ventricular (LV) dysfunction (systolic or diastolic).
RESULTS: Of the 311 women included (age 39 ± 9), 70% were HIV and 20% HCV positive. Forty three participants (13.8%) developed LV dysfunction, of which 79.1% was diastolic. Compared to participants with neither infection, the group with HIV-HCV coinfection showed a significantly increased risk of incident LV dysfunction after adjustment for risk factors (RR = 2.96 [95% CI = 1.05-8.31]), but associations for the HCV monoinfected and HIV monoinfected groups were not statistically significant (RR = 2.54 [0.83-7.73] and RR = 1.66 [0.65-4.25], respectively). Comparison of HCV-positive and HCV-negative women showed a significantly increased risk independent of covariates (RR = 1.96 [1.02-3.77]), but this was not the case for HIV-positive vs. HIV-negative women (RR = 1.43 [0.76-2.69]). There was no evidence of HCV-by-HIV interaction. A more restrictive definition of LV diastolic dysfunction led to fewer incident cases, but a similar, though non-significant, risk estimate for HCV.
CONCLUSIONS: Among middle-aged women, HCV but not HIV infection was associated with a pronounced risk of incident LV dysfunction. Although the influence of residual confounding cannot be excluded, these findings bolster the potential benefits that could be realized by adopting recent recommendations for expanding HCV screening and treatment.
