Farook N, et al. - Researchers aimed at developing a comparative diagnostic model using Bayesian statistics for exercise treadmill test (ETT) and stress echocardiogram (ECHO) to calculate post-test diagnostic risk of major adverse cardiac events (MACE) using HEART (history, electrocardiogram, age, risk factors, and troponin) risk score as predictor of pretest probability. Observations revealed that in low- and intermediate-risk patients, this Bayesian analysis demonstrated slight superiority of stress ECHO over ETT in ruling out MACE.
