Starting soon · Early Phase 1

Conditions studied: Healthy Subjects (HS), Cardiovascular Diseases (CVD)

In brief

What if heart disease starts outside the heart? This research will study how to simultaneously assess brain and body physiology, how they are jointly related to heart function, and how their response to physical and mental stress differs in patients with heart disease.
