The aim: to study the clinical, angiographic and functional parameters, and their relation to the decision on percutaneous coronary intervention (PCI) in stable coronary artery disease (CAD) patients with intermediate coronary stenoses (ІСS) at patient and lesion levels. Materials and methods. The cross-sectional study enrolled 123 patients (62±9 years; 73,2 % males) with stable CAD and angiographically ICS (50-90 %). Stable angina CCS class II (CCSII) was diagnosed in 70 (56,9 %) patients, class III (CCSIII) – 29 (23,6 %); 24 (19,5 %) patients were free from angina (Afree). Fractional flow reserve (FFR) was assessed in 74 (60,2 %) patients (min per patient). The hemodynamically significant lesion was considered if FFR ≤0,80 a.u. The decision to perform PCI was undertaken in 93 (76 %) patients. In addition, the functional data from 128 lesions were analyzed. Results. The CCSIII group was characterized by less frequent previous PCI (21 % vs. 46 % in the pooled group [CCSII + Afree]; р=0,018); the predominance of cases with (max) severe [70-90 %] coronary stenosis (96 % vs. 78 % in CCSII and 54 % in Afree; ptrend
