Effect of left ventricular dysfunction and viral load on risk of sudden cardiac death in patients with human immunodeficiency virus. Human immunodeficiency virus (HIV)-infected patients are disproportionately affected by cardiovascular disease and sudden cardiac death (SCD). Whether left ventricular (LV) dysfunction predicts SCD in those with HIV is unknown. We sought to determine the impact of LV dysfunction on SCD in patients with HIV. We previously characterized all SCDs and acquired immunodeficiency syndrome (AIDS) deaths in 2,860 consecutive patients in a public HIV clinic from 2000 to 2009. Transthoracic echocardiograms (TTEs) performed during the study period were identified.
