Background To compare cost-effectiveness and utility of four clinical algorithms to diagnose obstructive coronary atherosclerotic heart disease (CAD), we compared exercise ECG (ExECG), stress single photon emission computed tomography (SPECT), positron emission tomography (PET), and coronary angiography.
Methods and Results Published data and a straightforward mathematical model based on Bayes'theorem were used to compare strategies.
Effectiveness was defined as the number of patients with diagnosed CAD, and utility was defined as the clinical outcome, ie, the number of quality-adjusted life years (QALY) extended by therapy after the diagnosis of CAD.
Our model used published values for costs, accuracy, and complication rates of tests.
Analysis of the model indicates the following results.
