This review considers the clinical and epidemiological significance of hospitalizations for decompensated heart failure, as well as using it as an indicator of therapy effectiveness. The data on the frequency of using medications that reduce the hospitalization risk in randomized clinical trials and in real practice are presented. The reasons for inadequate prescription of drugs for the treatment of heart failure with reduced ejection fraction and their use in insufficient doses, which include therapeutic inertness and physiological limitations, as well as the need to introduce drugs with alternative mechanisms of action into clinical practice, are iscussed.

The main reason for incomplete myocardial revascularization is the presence of chronic coronary total occlusion (CTO), which is detected in every fourth patient during coronary angiography. At the same time, a generally accepted approach to the treatment of CTO has not yet been developed.Aim. To assess the rationale of complete myocardial revascularization in patients with multivessel coronary artery disease (CAD) with chronic total occlusion and high surgical risk.Material and methods. This retrospective, open-label, non-randomized clinical trial was carried out included 180 patients multivessel CAD and CTO. The patients underwent endovascular surgery for complete myocardial revascularization. Depending on the success of surgery, the patients were divided into groups of complete and incomplete myocardial revascularization. Endpoints were death, acute coronary syndrome, re-revascularization after 1-year follow-up. Left ventricular (LV) contractility and clinical status of patients in the study groups after 1 year of observation was assessed.Results. The median follow-up was 12,1 months. The successful rate of revascularization was 79,4%. The incidence of main composite endpoint in the group of complete myocardial revascularization was 5,59%, while in the group of incomplete revascularizations — 21,6% (p=0,005).Conclusion. The study showed that low incidence of intraoperative complications and a high successful rate of revascularization are characteristic of complete myocardial revascularization in patients at high surgical risk with multivessel CAD and CTO. Complete myocardial revascularization leads to a significant decrease in the incidence of major coronary events.

Aim. To evaluate long term results of percutaneous coronary interventions (PCI) in stable ischemic heart disease patients (IHD) under real clinical circumstances.Material and methods. The PCI group consisted of 150 patients with stable IHD after PCI, randomly selected from the Registry of Coronary Angiography. Comparison group consisted of randomly selected from the Registry 150 patients with stable IHD receiving only drug therapy (DT).Results. In long term perion it was found that total mortality (4,0% vs. 11,3%, p=0,017) and cardiovascular mortality (3,3% vs. 10,7%, p=0,013) were lower in PCI group. After PCI there was rarer coronary bypass operation need (2,0% vs. 10,0%, p=0,004). By the prevalence of myocardial infarction in compared groups there were no statistically significant differences (6,7% vs. 5,3%, p=0,627). Kaplan-Meier curve analysis showed that positive effect of PCI was fulfilled in 15 months and progressively increased until the end of follow-up. In stepped regression of Cox proportional risks it was revealed that in long term period PCI performing associated with the increase of survival rate 2,8 times (RR=2,81, 95% CI 1,03-7,69, p=0,044). Long term survival showed independent relation with the grade of coronary lesion. In PCI group, as in DT group, there were no positive dynamics of angina functional classes. In MT group during the follow-up functional class of heart failure became harder than in PCI group, and in PCI groupthere were no significant dynamics of heart failure functional class.Conclusion. Real clinical practice proved the effectiveness of PCI with DT in treatment of stable IHD. In long term results evaluation, PCI for stable IHD associated with the increase of survival 2,8 times comparing with the group with only DT. Positive PCI effect realized after 15 months and progressively increased to the end of follow-up.

In the review the most prominent foreign registries of stroke are explored, those concern the evaluation of the treatment, and several Russian registries. The importance of treatment evaluation is discussed, and better and worse sides of the evaluating systems are estimated as their possibility to be used it Russia.
