ABSTRACT
OBJECTIVE: The aim: To investigate the clinical and pathogenetic peculiarities of formation and course of CCP and the relationship between clinical, hemodynamic and neurohumoral factors of comorbidity development in COPD combined with arterial hypertension (AH). PATIENTS AND METHODS: Materials and methods: The object of the study were 484 patients with COPD. Among them, 350 patients with CCP as a result of cardiac insufficiency/severe congestive heart failure (COPD III-IV) out of aggravation, combined with AH II stage (non-symptomatic organ damage) and 1 - 3 grades, including 55 patients (43 men, 12 women) with compensated CCP (average age 43.7 ± 3.4 years), and 295 patients (212 men and 83 women) with decompensated CCP and chronic heart failure (CHF), average age 63.2 ± 8.9 years. RESULTS: Results: It was found that the development and progression of the left and right CHF in patients with CCP combined with AH occurs due to the disorders of the central hemodynamic, progression of pulmonary hypertension, bronchial obstruction syndrome, neurohumoral and systemic immunoinflammatory activation, disorders of endothelial regulation of vascular tension, overproduction of epithelial and mitogenic growth factors, inducers of apoptosis, and is accompanied by increasing levels of natriuretic peptides. CONCLUSION: Conclusions: The main pathogenetic formation mechanisms of the heart failure on the background of CCP combined with AH are: neurohumoral and systematic immune-inflammatory activation with the development of endothelial dysfunction and (neo)angiogenesis, induction of pathological apoptosis, increase in the intrathoracic pressure, and deposition of blood in the extrathoracic tissues, which result in pulmonary and systemic hypertension, metabolic and hemodynamic remodelling and heart dysfunction.

OBJECTIVE: Introduction: Modern strategies of STEMI/NSTEMI management, that include revascularization by coronary stenting, bypass grafting, nowadays are used in 30-40% of urgent patients of such category. The prevalent part of patients is treated by administration of the optimal drug therapy. The aim of the research was to study the influence of trimetazidine and levocarnitine on the clinical course of STEMI/NSTEMI. PATIENTS AND METHODS: Materials and methods: 100 patients with STEMI/NSTEMI were included into the research. Depending on the therapy scheme, patients were divided into three groups and the control one. Determination of the key parameters was performed initially after hospitalization and at the day of patient discharge. RESULTS: Results: Promising results were shown while slowing the myocardial fibrosing. Limiting of the infarcted and `stunned` myocardium area resulted in ejection fraction increase, increase of the myocardial reserve, measured by echocardiographic indexes. CONCLUSION: Conclusions: Decreasing of myocardial fibrosing can be potentiated by the pharmacological postconditioning as well as limiting of the necrotic myocardium area and increase of viable myocardium area. Pharmacological postconditioning is effective and save, that can be proved by the absence of any serious complications.
