In Person Lecture: Human Cardiac Metabolism

About this Seminar

Heart failure is understood to be in part a metabolic disorder, but most of our understanding of cardiac metabolism stems from pre-clinical models. Dr. Arnay and his lab therefore leveraged modern mass spectrometry and metabolomics to probe cardiac metabolism in human health and disease in two contexts: (1) arteriovenous differences in plasma metabolite concentrations across the cardiac microvasculature in 120 patients undergoing elective procedures requiring placement of a coronary sinus catheter, and (2) tissue samples from excised hearts from patients undergoing transplantation for non-ischemic dilated cardiomyopathy or from organ donors with normal cardiac function. From the former, the lab calculated flux of hundreds metabolites in and out of the heart in health and disease, while from the latter researchers gathered mechanistic insight into metabolic alterations in heart failure.
