Current Research Interests

Dr. Tremmel studies sex differences in cardiovascular disease. She is currently investigating sex differences in coronary endothelial function, plaque deposition, and the microcirculation of women and men who present with chest pain, but have normal appearing coronary arteries by angiography. She is also leading Stanford’s participation in the multi-center VIRGO trial, which is evaluating sex differences in young patients who present with myocardial infarction. Other active research projects include sex differences in chronic total coronary occlusions, the impact of stress on anginal symptoms, and vascular access site complications. Dr. Tremmel keeps Stanford’s Tako-tsubo Patient Registry and is conducting a multi-center study to investigate the relationship of stress and coping to genetic polymorphisms in patients with Tako-tsubo.
