Applying Pulse Spectrum Analysis to Facilitate the Diagnosis of Coronary Artery Disease

Figure 2

Receiver operator curves (ROC) comparing Model 1 (influence factors: age, gender, BMI, hypertension, diabetes, and hyperlipidemia) with Model 2 (influence factors and relative spectral energy values) for predicting coronary artery disease. Area under curve (AUC) of Model 1 and Model 2 is 0.788 and 0.856, respectively.
