HIV may increase risk of heart failure

Several factors related to HIV infection, including drug treatments, behavioral habits and physiological changes may increase the risk of heart failure among patients who suffer from the sexually transmitted disease (STD), according to a recent study published in the journal Archives of Internal Medicine.

Researchers collected data from a group of veterans, some of whom were HIV-positive. The study's results showed that there was an increased risk of heart failure among HIV patients, regardless of whether or not they had a prior history of cardiovascular problems.

The scientists explained that antiretroviral drugs, such as protease inhibitors, and low blood levels of CD4+ cells typically caused by the virus contribute to the elevated risk of a cardiovascular event. They also noted that HIV-infected veterans were more likely than the other subjects to have coexisting hepatitis C, and abuse drugs or alcohol. However, these individuals were less likely than participants who did not suffer from HIV to have common risk factors such as hypertension or diabetes.

People can help prevent the spread of HIV by practicing safe sex with the use of condoms and seeking regular STD screening, especially if they engage in intercourse with multiple partners.
