Low-grade systemic inflammation, myocardial stress, and extracellular matrix fibrosis lead to heart failure with preserved ejection fraction (HFpEF). The HFA-PEFF diagnostic algorithm and the H2FPEF score are recommended for detecting HFpEF. Their low compliance is the reason for improving the methods for diagnosing HFpEF. Modern paraclinical diagnostics of HFpEF includes an assessment of the left ventricular filling pressure during diastolic stress test. Phase analysis of left atrial strain during resting echocardiography may be promising to conclude an increase in mean left atrial pressure. Research interest is growing in relation to biomarkers involved in the regulation of collagen synthesis. Together, paraclinical diagnostics help to characterize sequential morphofunctional cardiac remodeling, increasing the possibility of HFpEF detection.

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.

Aim of this study was to assess clinical profile, treatment and long-term results in patients with left main coronary artery disease in a real-world practice. 225 cases were analyzed. Long-term results were evaluated from 213 (97.7%) patients. Median follow-up period was 49 months. Fifty two (23.9%) patients received nonsurgical treatment, coronary artery bypass grafting (CABG) was performed in 106 (48.6%) patients, percutaneous coronary interventions (PCI) in 60 (27.5%) patients. Patients of nonsurgical group had more severe clinical profile compared with PCI group. There was no differences between nonsurgical and CABG groups as well as between CABG and PCI groups in clinical profile. Major adverse cardiac and cerebrovascular event rate was higher in nonsurgical group. There was no difference between CABG and PCI groups. Survival in CABG and PCI groups was higher compared with nonsurgical group. Survival effect of revascularization was observed immediately (before 6 months) and continued long-term (more than 60 months). Revascularization was independent predictor of improved long-term survival. After diagnosis of left main coronary artery stenosis PCI was performed more quickly than CABG.
