The observation period was uneventful, and serial cardiac troponin T was negative in 404 patients. These patients were eligible to undergo dobutamine stress echocardiography. However, in 27 patients dobutamine stress echocardiography could not be performed. The remaining 377 patients underwent dobutamine stress echo cohort and were considered for further analysis.
