Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Prospectively enroll patients with history of severe myocardial infarction, cardiomyopathy, heart failure or prior nuclear scans with resting perfusion defects. Patients were approached in the nuclear stress lab prior to scheduled stress test. Recruitment period was between 3/20/2012 and 2/14/2014.
