Physiologic Assessment of Microvascular Function in Heart Transplant Patients
Trial Parameters
Condition Cardiac Allograft Vasculopathy
Sponsor Samsung Medical Center
Study Type OBSERVATIONAL
Phase N/A
Enrollment 200
Sex ALL
Min Age 18 Years
Max Age 85 Years
Start Date 2016-05

Brief Summary
The aim of the study is to evaluate the impact of early microvascular disease assessed by coronary physiologic indices such as fractional flow reserve (FFR), coronary flow reserve (CFR), index of microvascular resistance (IMR) on future occurrence of cardiac allograft vasculopathy (CAV) in heart transplant recipients.
