Clinical and economic impact of stress echocardiography compared with exercise electrocardiography in patients with suspected acute coronary syndrome but negative troponin: a prospective randomized controlled study

摘要

Aims Patients attending hospital with suspected acute coronary syndrome (ACS), non-diagnostic electrocardiogram (ECG), and negative troponin present a diagnostic dilemma for admitting physicians. We sought to determine the clinical and economic impact of stress echocardiography (SEcho) when compared with exercise ECG (ExECG) in the assessment of these patients.
