Can You Differentiate False Positive and True Positive Results in Coronary Arter...

• False positive results are common in treadmill exercise ECG testing for obstructive coronary artery disease screening.
• It is important to distinguish between a false positive and a true positive to avoid unnecessary referrals for invasive coronary angiography.
• The study analyzed a cohort of patients referred for ICA for stable coronary artery disease diagnosis.
• Traditional and nontraditional coronary artery disease risk factors were assessed.
• Modified Framingham risk score, symptoms, pre-test probability of OCAD, left ventricular ejection fraction and ICA results were also evaluated.
• A FP TMT result was defined as an ischemic response and no OCAD.
• The predictors of a FP result were determined through statistical tests and multivariate analysis.
• The discriminatory power of a model based on predictive factors was assessed.
• The study was conducted in a single tertiary-care center from 2006-2011.
• The area under the ROC curve was used to evaluate the model's performance.
