People with HIV are at increased risk of cardiac dysfunction; however, limited tools are available to identify patients at highest risk for future cardiac disease. We performed proteomic profiling using plasma samples from children and young adults with perinatally acquired HIV without clinical cardiac disease, comparing samples from participants with and without an abnormal myocardial performance index (MPI). We identified four proteins independently associated with subclinical cardiac dysfunction: ST2, CA1, EN-RAGE, and VSIG2.
