Spontaneous Coronary Artery Dissection

Dr. Jennifer Tremmel

Dr. Tremmel is an interventional cardiologist who founded and directs the Women’s Heart Health Program at Stanford. She conducts research in women’s heart health and sex differences in cardiovascular disease, and regularly speaks around the country. She has several ongoing studies investigating sex differences in coronary endothelial function, microvascular function, and myocardial bridging in women and men who present with chest pain, but have normal appearing coronary arteries by angiography. She has been a leading figure in transradial procedures since 2009, in which coronary angiography and intervention are performed from the wrist rather than the groin. She started doing this because women are 2-3x more likely to bleed from the groin than men, and she wanted to eliminate this sex disparity in the cath lab. She regularly teaches this procedure to other interventionalists and speaks internationally on the topic, including an appearance on the Dr. Oz show. Dr. Tremmel is also an expert in spontaneous coronary artery dissection (SCAD), and is the principal investigator of the first international collaboration, evaluating differences between patients who are peri-partum when they have their SCAD event vs. those who are not. In addition, she speaks about SCAD whenever she can, with the hope of increasing awareness among patients, as well as physicians.
