Abstract
- AIM To assess the temporal trends in the usage pattern of non-invasive testing before invasive coronary angiography (ICA) and its diagnostic yield in patients with suspected coronary artery disease (CAD). METHODS Cross-sectional observational multicenter study of 4805 consecutive patients (60% male, mean age 66 ± 10 years) with suspected CAD undergoing elective ICA due to angina pectoris in two centers, from 2008 to 2017. The use of noninvasive testing and the proportion of patients with obstructive CAD (defined as the presence of at least one ≥50% stenosis on ICA) were assessed. RESULTS There were 4038 (84%) patients referred for ICA with positive noninvasive test, mainly SPECT (38%, n = 1828) and exercise ECG (36%, n = 1731). Obstructive CAD was found in 54.5% (n = 2621) of the patients and 37.9% (n = 1822) underwent revascularization. The prevalence of obstructive CAD was higher in patients with vs. without previous noninvasive testing (55.8% vs. 48.1%, respectively, P < 0.001) and tended to decrease during the study period (P for trend
