Myocardial dysfunction in patients infected with HIV: prevalence and risk factors

Abstract

There was a high prevalence and wide range of myocardial dysfunction in HIV positive patients. Dilated cardiomyopathy was a feature of advanced HIV disease and affected all major risk groups for HIV infection. In contrast, isolated dilatation of either ventricle occurred at an earlier stage of HIV infection and, particularly in the case of the right ventricle, often was transient. Neither treatment with zidovudine nor infection with Toxoplasma gondii or cytomegalovirus seemed to be responsible for these findings.
