Aims: to study the clinical and hemodynamic efficacy of percutaneous coronary intervention in patients with coronary artery disease with a low left ventricular ejection fraction in the near and long-term follow-up. Methods and results: In a prospective observation we studied analysis of the life and dynamics parameters of intracardiac hemodynamics in 65 (47.1%) patients with low left ventricular ejection fraction (less than 45%). In our study, the incidence of angiographic success with stent implantation in patients with coronary artery disease with a low left ventricular ejection fraction was 92.3% (60), the immediate success of the procedure was 85.7% (59), and the clinical success of in-hospital 85.7% (59). The survival rate in the long term without the development of large cardiac complications was 83.1% (54). The incidence of MACE was 16.9% (11). The LVEF increasing was observed in 60% (39) patients, decreasing of the LVEF in 15.4% (10) patients and in 10.8% (7) patients it was not changed. In patients with a positive growth in LVEF after PCI in the long-term observation reversibility of LV remodeling processes were registered. Conclusion: Percutaneous coronary intervention in patients with coronary heart disease with decreased myocardial contractility improves left ventricular ejection fraction, thereby contributing to improved quality of life. In the long period, there was significant increasing in the average left ventricular ejection fraction up to 43,5% ± 6.9% and initial index was 38.5 ± 4.9% (p = 0.000). |
