Biography
My clinical training is as an advanced heart failure physician with formal research training in patient oriented translational research. My research program is supported by NIH and investigator-initiated industry sources and uses techniques of both translational and clinical research to further the mechanistic understanding of cardiac-renal interactions, fluid and sodium homeostasis, and diuretic resistance. The primary approach of my current research program is prospective mechanistic human studies in heart failure and kidney disease patients, for which we have established extensive infrastructure. N My lab has extensive expertise in biomarker research has established and maintains an extensive bioassay resource with the capability to determine an extensive range of analytes in human biological samples with complexity ranging from simple serum chemistries to complex analytes such as ultra-trace lithium by inductively coupled plasma mass spectrometry, deuterium concentration by IRMS, high dimension multiplex protein assays, and large and small molecules by liquid chromatography mass spectrometry.

Overview
Jeffrey Testani, MD, MTR (master of science in translational research) is a cardiologist who specializes in advanced heart failure. People with advanced heart failure experience shortness of breath and other symptoms even while at rest despite conventional therapies and strategies.
Dr. Testani’s work focuses on the connections between fluid build-up and heart failure. When the heart is unable to pump an adequate supply of blood to the body, the kidneys respond by increasing the volume of fluids. Dr. Testani and fellow researchers have determined that a diabetes medication can reduce fluid build-up in diabetic patients with heart failure.
Dr. Tetany’s current research involves studying hundreds of heart patients, producing 500,000 biospecimens, or samples, that can be used to determine specific paths and characteristics that lead to heart failure.
Dr. Testani is an associate professor of medicine (cardiology) at Yale School of Medicine.
