Andrew P. Ambrosy, MD, is a practicing cardiologist at Kaiser Permanente in San Francisco as well as research scientist within the Division of Research’s section on Cardiovascular and Metabolic Conditions. His research interests are ischemic heart disease, cardiomyopathy, and heart failure, and he has extensive prior experience in health outcomes, implementation science, and traditional and pragmatic clinical trials. He previously completed a dedicated research fellowship at Duke University Medical Center/Duke Clinical Research Institute where he was a member of the operations team for the National Heart, Lung, and Blood Institute-funded Heart Failure Network and several industry-sponsored clinical trials. He has presented his research at national and international scientific meetings and has authored approximately 100 peer-reviewed manuscripts.

Partnership for Anemia: Clinical and Translational Trials in the Elderly (PACTTE)

Within the CVRN-HF Network, and in collaboration with NIA-sponsored PACTTE consortium investigators, we will examine the following among a large, multi-center cohort of elderly patients with heart failure with reduced or preserved left ventricular systolic function: 1) to characterize the contemporary frequency of testing for and prevalence of anemia; 2) to assess the frequency, timing and extent of evaluation for reversible causes of anemia in those with documented anemia; 3) to evaluate contemporary adverse event rates by hemoglobin level; and 4) to examine the feasibility of conducting a potential pragmatic clinical trial of systematic evaluation of anemia in elderly heart failure patients.
