Critical Care Cardiology Trials Network (CCCTN)

Progressive changes in cardiac critical care have driven a need for innovation in research and clinical care. The Critical Care Cardiology Trials Network (CCCTN) is a collaborative research network drawn from national leaders in critical care cardiology and coordinated by the TIMI Study Group.  Our mission is to design and execute observational studies and clinical trials that will advance the care of patients who require cardiac critical care. Learn about the CCCTN COVID-PACT clinical trial, a multicenter, randomized, open-label, 2 x 2 factorial design trial of full-dose anticoagulation vs. standard-dose prophylactic anticoagulation and antiplatelet therapy vs. no antiplatelet therapy on the risk of venous or arterial thrombotic events in ICU patients with COVID-19. Study patients will be followed until their 28th day or hospital discharge, whichever comes first.
