In patients with suspected CAD and normal ECG, a nomogram model based on clinical and exercise variables predicted mortality.

Patients: Patients ≥ 30 years of age (derivation group, n = 33 268, median age 52 y, 62% men; validation group, n = 5821, median age 55 y, 55% men) with normal ECGs and suspected CAD referred for symptom-limited exercise treadmill testing. Exclusion criteria were coronary disease, heart failure, left ventricular systolic dysfunction, cardiomyopathy, valvular or congenital heart disease, past renal or cardiac transplantation, atrial fibrillation, digitalis use, pacemaker or defibrillator placement, or end-stage renal disease.
