Safety of regadenoson positron emission tomography stress testing in orthotopic heart transplant patients.

ABSTRACT:

Objectives

We sought to determine the safety of regadenoson (REG) stress testing in patients who have undergone orthotopic heart transplantation (OHT).

Background

Routine screening for cardiac allograft vasculopathy (CAV) is necessary after OHT. Adenosine stress is contraindicated after heart transplantation due to supersensitivity in denervated hearts. Safety of regadenoson stress following OHT has not been well studied.

Methods

We retrospectively reviewed data from OHT patients (N = 123) who were referred to REG stress testing. Medical records were reviewed to determine hemodynamic and ECG response to regadenoson and to identify adverse reactions.

Results

No serious adverse events occurred. No life-threatening arrhythmias or hemodynamic changes occurred. Comm
