Platelet Function and Sildenafil Use During Left Ventricular Assist Device Support
Clinical outcome studies have shown that sildenafil is associated with reduced mortality and thrombotic events such as ischemic stroke during contemporary left ventricular assist device (LVAD) support. Sildenafil has anti-platelet properties but its relation to platelet function during LVAD support is uncertain.

Sildenafil Reduces Risk of Ischemic Stroke and Pump Thrombosis with Ongoing Low Level Hemolysis During Heart Mate II Support
Low level hemolysis after Heart Mate (HM) II implantation, as evident by an elevated discharge lactate dehydrogenase (LDH) level>400 U/L, is linked to subsequent thrombotic events. Free hemoglobin from ongoing hemolysis scavenges nitric oxide (NO) to create a NO deficiency which can augment platelet function. We hypothesized the potentiation of NO signaling during low level hemolysis with a phosphodiesterase-5 inhibitor, sildenafil, may lead to reduced thrombotic events.
