Patients with left bundle branch block (LBBB) were excluded from the exercise stress test and scintigraphy analysis.
↵2-150 Negative result only accepted if at least 85% of predicted maximum heart rate achieved.
CAD, number of patients with established coronary artery disease; EST, exercise stress test; LVH, left ventricular hypertrophy detected by echocardiography, defined as thickness of interventricular septum and posterior wall > 11 mm; n, number of patients with clinical characteristics suggestive of coronary artery disease.
