As people with HIV age, their risk of heart attack increases far more if they also have untreated hepatitis C virus, even if their HIV is treated, according to new research published today in the Journal of the American Heart Association.

Since the introduction of antiretroviral therapies to treat HIV in the late 1990s, the lifespan of people with HIV has increased dramatically. However, even with treatment, studies have found the heart disease risk among people with HIV is at least 50% higher than people without HIV. This new study evaluated if people with HIV who also have hepatitis C – a viral liver infection – have a higher risk of heart attack.

Researchers analyzed health information for 23,361 people with HIV in the North American AIDS Cohort Collaboration on Research and Design between 2000 and 2017 and who had initiated antiretroviral treatment for HIV. All were between 40 to 79 years of age when they enrolled in the NA-ACCORD study . One in 5 study participants were also positive for hepatitis C. During a median follow-up of about 4 years, the researchers compared the occurrence of a heart attack between the HIV-only and the HIV-hepatitis C co-infected groups as a whole, and by each decade of age.

The analysis found:

1. With each decade of increasing age, heart attacks increased 30% in people with HIV alone and 85% in those who were also positive for hepatitis C.

2. The risk of heart attack increased in participants who also had traditional heart disease risk factors such as high blood pressure (more than 3 times), smoking (90%) and Type 2 diabetes (46%).

3. The risk of heart attack was also (40%) higher in participants with certain HIV-related factors such as low levels of CD4 immune cells and 45% in those who took protease inhibitors.
