Heart Blood Flow Study in Adults With or Without Spontaneous Coronary Artery Dissection Using Stress Contrast Echocardiography

What this Trial Is About

Researchers are exploring how microvascular blood flow and blood pressure respond to stress in people with a history of spontaneous coronary artery dissection SCAD. This observational study uses stress contrast echocardiography to fill existing knowledge gaps about heart function in these patients compared to healthy individuals. The study is sponsored by Mayo Clinic and involves both participants with SCAD and healthy volunteers. The main procedure studied is stress echocardiography with contrast, which evaluates heart function and blood flow changes under stress. Participants are grouped into those with SCAD history and healthy subjects with no significant medical issues. The study measures changes in microvascular function, blood pressure, and heart rate immediately before and after the stress echocardiography. Participants will undergo baseline assessments followed by the stress echocardiography test with contrast. Researchers will monitor changes in heart performance and vital signs during the procedure. The study aims to understand the differences in cardiovascular responses between SCAD patients and healthy individuals. Participation involves a single visit with focused heart imaging and monitoring, with no ongoing treatment or long-term follow-up described.
