A Study to Analyze the Role of Sympathetic Nervous System in Spontaneous Coronary Artery Dissection
June 5, 2023 updated by: Marysia Tweet, Mayo Clinic
Role of the Neurovascular System in Spontaneous Coronary Artery Dissection (SCAD)
The purpose of this research is to compare sympathetic function (flight or fight system) and arterial health including structure and mechanics of participants with history of spontaneous coronary artery dissection (SCAD) to age and sex matched control participants.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Other: Spontaneous coronary artery dissection (SCAD) group
Subject with a history of SCAD will undergo a series of diagnostic studies to assess neurovascular function.
|
We will measure arterial stiffness using arterial tonometry.
We will collect limited ultrasound images of the heart.
We will perform ultrasound imaging of the carotid artery.
We will measure the elastic properties of the arteries using elastography.
We will measure the ankle-brachial index to assess peripheral artery blood flow.
We will measure sympathetic nerve activity at rest and in response to isometric handgrip, mental stress test, cold pressor test, Valsalva maneuvers.
