Vedant Pargaonkar
Basic Life Research Scientist, Medicine - Med/Cardiovascular Medicine
BioMy long-term research interests involve development of algorithms using computational methods for early detection of coronary pathophysiology including, endothelial dysfunction and microvascular dysfunction (MVD) and/or a myocardial bridge (MB) in patients with angina and no obstructive coronary artery disease (NOCAD) and the identification of novel target therapies for primary prevention and improved prognosis in these patients. Under the mentorship of Dr. Jennifer Tremmel in Cardiovascular medicine at Stanford, I have been systematically studying to better understand the underlying pathophysiology of these patients, as well as the optimal use of diagnostic testing and treatment using the angina and no-obstructive CAD Registry at Stanford. In collaboration with other investigators in this field, we have published multiple scientific articles highlighting the limitations of current testing in this population and identification of novel diagnostic tools for early diagnosis and management of patients with angina and no obstructive CAD. My research also focuses on myocardial infarction (MI) in women, particularly spontaneous coronary artery dissection (SCAD). I have been involved in the design and execution of the first international collaborative study in SCAD, investigating peripartum vs. non-peripartum SCAD. This is analyzing the largest cohort of patients recruited from multiple US and non-US sites to understand the pathophysiological differences in these patient cohorts.

Jane Parnes
Professor of Medicine, Emerita
Current Research and Scholarly InterestsThe lab is studying the mechanisms controlling B cell responsiveness and the balance between tolerance and autoimmunity. B cells deficient in CD72 are hyperresponsive to stimulation through the B cell receptor. We are examining the alterations in B cell signaling in these B cells and the mechanisms by which CD72 deficiency partially abrogates anergic tolerance. We hope to learn how deficiency in CD72 leads to spontaneous autoimmunity and increased susceptibility to induced autoimmune disease.

His group studies the genetic variations and environmental exposures that are associated with conditions such as atrial fibrillation and heart failure. He has led the studies of atrial fibrillation in Women's Health Initiative, one of the largest nation-wide population-based cohorts. He is currently conducting a large study monitoring for silent or asymptomatic atrial fibrillation in women from the WHI randomized to exercise intervention, and was co-PI of the Apple Heart Study, a clinical trial that validated the ability of a smartwatch to detect atrial fibrillation. He is now PI of the Clinical Coordinating Center at Stanford for the REACT-AF which is a clinical trial to evaluate efficacy and safety of a "pill-in-the pocket" approach to anticoagulation for AF using a smartwatch. He is interested in understanding the paradox that atrial fibrillation is less common in African Americans and Hispanics, despite a greater burden of risk factors such as hypertension. As director of the Stanford Inherited Arrhythmia Clinic, he evaluates families with rare inherited arrhythmias associated with sudden death such as Long QT and Brugada Syndromes and explores their links with novel genes. He also studies the genetic causes of very early onset atrial fibrillation. He also studies how best to use the electrocardiogram and imaging modalities using Machine Learning techniques to identify patients at risk for cardiovascular disease.
