Background. Studying the use of transcutaneous coronary interventions in patients with different forms of IHD and left ventricular systolic dysfunction and effects of morpho-functional factors on results of these interventions is of special scientific and practical interest. Aim. To study effects of morpho-functional factors on results of transcutaneous coronary interventions in patients with different forms of IHD and left ventricular systolic dysfunction and to identify predictors of beneficial prognosis. Materials and methods. Between January 1, 2013 and December 1, 2014, diagnostic coronary angiography with subsequent coronary stenting was performed in 138 IHD patients with low left ventricular ejection fraction. The study group included 65 IHD patients with left ventricular dysfunction for whom remote results were evaluated. Results. Remote survival without major coronary complications (MCC) was 83.1% (54). Incidence of MCC was 16.9% (11); for 12.3% (8) of patients, MCCs were fatal; in 3.1% (2) MCCs resulted in non-fatal MI; and for 1.5% (1) of patients, coronary bypass was performed. In 60% (39) of patients, LV EF was increased; in 15.4% (10) of patients, LV EF was decreased; and in 10.8% (7) of patients, EF remained unchanged. After TCI, increased LV EF was more frequently observed in the group of patients with FC II–IV (CCS) stable angina (p=0.036, χ2=4.385) and in patients aged 51 to 60 (p=0.019, χ2=5.545). Conclusion. Therefore, analysis of the accumulated experience shows that in IHD patients with left ventricular systolic dysfunction, TCI without identification of viable myocardium is a sufficiently safe and effective method of myocardial revascularization. Following TCI, increased LV EF was significantly more frequently observed in the group of patients with FC II–IV (CCS) stable angina (p=0.036, χ2=4.385) and in patients aged 51 to 60 (p=0.019, χ2=5.545).
