Dr. Lima has dedicated a large portion of his overall scientific effort in the elucidation of mechanisms of heart failure in population studies (MESA and CARDIA)‎. Specifically, he has investigated the pathogenesis of heart failure with preserved ejection fraction (HFpEF) using RO 1 Ancillary studies to MESA for which he was the PI. He used MRI tagging to define myocardial deformation in cardiac remodeling and, as PI of the MESA MRI reading center since 2008, he performed studies to characterize the role of fibrosis as a major determinant of HFpEF. Overall, his primary scientific contributions to cardiovascular medicine have been the development of MRI methods to measure infarct size and the extent and severity of microvascular obstruction in patients with acute myocardial infarction. The majority of Dr. Lima’s clinical efforts have been dedicated to clinical scholarship and program development at the Johns Hopkins Hospital. He directed the Echocardiography Laboratory at Hopkins for several years and spearheaded pioneering programs in cardiovascular MRI and cardiac CT. His leadership in mentoring cardiology and radiology trainees in cardiovascular imaging has also been significant both clinically and in clinical investigation. Currently, Dr. Lima is a Professor of Medicine with joint appointments in the Departments of Radiology and Epidemiology, as well as Director of Cardiovascular Imaging at Johns Hopkins Hospital. Dr. Lima’s research interests are concentrated on the development and application of imaging technology to address scientific and clinical problems involving the heart and vascular system. Dr. Lima has been the PI for the MESA, CARDIA, EDIC, CorE64, CorE320, ALLSTAR, CCTRN, ESCAPE, HOPE, MESA-COPD, SSCOR, SOL, and SPIROMICS Imaging Core Laboratory studies. The proposed work represents a natural continuation of his efforts dedicated to the elucidation of heart failure and aging related cardiovascular remodeling in human populations.
