ABSTRACT
OBJECTIVE: In European Society of Cardiology/European Association for Cardio-Thoracic Surgery (ESC/EACTS) guidelines, six indications have been proposed for making a decision on myocardial revascularization in patients with stable coronary artery disease (CAD). Our aim was to study a discrepancy between the actual clinical situation and ESC/EACTS indications on performing the revascularization in patients with CAD in Russia. DESIGN AND SETTING: We used retrospective clinical data on patients with stable CAD enrolled in the 2012-2015 Russian Registry of Hypertension, Coronary Artery Disease, and Chronic Heart Failure. PARTICIPANTS: A total of 1522 patients with CAD (aged 53.0 ± 8.5 years, 76.2% male) were used for analysis. INTERVENTIONS: All patients were divided into two groups: 591 patients with performed myocardial revascularization (named as R-CAD) and 931 patients refused from revascularization (named as NR-CAD). Factors associated with revascularization performance were identified by discriminant function analysis. MAIN OUTCOME MEASURES: ESC/EACTS indications for revascularization were assessed. RESULTS: A total of 1196 patients with CAD had any ESC/EACTS indication for revascularization, but only 40.2% of them had performed invasive coronary intervention. Myocardial revascularization was appropriate in 81.4% of R-CAD patients and 76.8% of NR-CAD patients. The main factor of revascularization performance was any stenosis >50% and grades III-IV of stable angina. With non-performed revascularization, the following factors were associated: limiting angina or angina equivalent, unresponsive to medical therapy, atherosclerotic peripheral arterial disease and increasing the New York Heart Association class of chronic heart failure. Most ESC/EACTS indications had little effect on decision-making on revascularization. CONCLUSION: There is a discrepancy between the actual clinical situation and ESC/EACTS guidelines on myocardial revascularization in patients with stable CAD in Russia.
