Result: The combined model - typical angina pectoris + risk factor (old age, male, dyslipidemia, smoking) - were predictive of coronary disease (89% patients having significant coronary stenosis with the specifity 73%); when combined the noninvasive diagnostic tests - ST depression in ECG at rest, Exercise ECG, abnormal movement of ventricular walls on echocardiography, the model increased a little bit sensitivity (93% 0 but the specificity increased significantly (88%).
