The primary goal of this project is to describe the clinical and physiologic characteristics of Spontaneous Coronary Artery Dissections (SCAD) in order to increase awareness, understanding, treatment and prevention of a potentially fatal cardiovascular event.

This study will be a retrospective and prospective review of medical course and current health of men and women with SCAD.

The purpose of this study is to determine differences in clinical and imaging presentation, in-hospital management and prognosis in peri-partum and non-peri-partum SCAD patients.

The purpose of this study is to identify and characterize heart rhythm disorders including atrial arrhythmias such as atrial fibrillation, ventricular arrhythmias such as ventricular tachycardia, conduction abnormalities, etc. among patients with spontaneous coronary artery dissection (SCAD).

The purpose of this research is to compare sympathetic function (flight or fight system), arterial structure and mechanics of participants with history of spontaneous coronary artery dissection (SCAD) to age and sex matched control participants.

The sympathetic function across the menstrual cycle in premenopausal women with a history of SCAD will also be compared to age-matched premenopausal women.
