Aim. Coronary stenting is the evidence-based treatment approach of stable angina. The objective was to determine the incidence of restenosis or atherosclerosis progression which led to the need for coronary angiography according to a single center registry data. Materials and methods. The procedure and clinical data of 3732 (2897 males) consecutive stable coronary artery disease patients undergoing coronary stenting, over five years between March 2010 and September 2014, were subject of this study. Over the next 4 years, 1487 (1173 males) patients were re-evaluated due to angina reoccurrence. 699 patients demonstrated the indications for coronary angiography. Results. The restenosis of the previously stented segment was detected in 84 (12%) cases, the progression of coronary atherosclerosis in 306 (44%), the combination of restenosis and atherosclerosis progression in 63 (9%), and the absence of these complications in 245 (35%) cases. The progression of coronary atherosclerosis was the leading indication for the repeat angiography and revascularization (44 and 58%, respectively); p0.05. The basal level of hsCRP2 mg/l had a prognostic significance for the development of combined event (the restenosis and atherosclerosis progression): AUC 0.65 (0.500.75), OR 3.0 (1.17.9), p0.05. Conclusion. The progression of coronary atherosclerosis was the leading indication for the repeat angiography and repeat revascularization during 2 years after coronary stenting. The hsCRP level 2 mg/l at baseline had a prognostic significance for the development of restenosis in previously stented segment and coronary atherosclerosis progression.
