Clinical Trial Summary

The main causes of chronic heart failure (CHF) are arterial hypertension and coronary artery disease, less often cardiomyopathy, pericarditis, metastatic myocardial lesions. It should be noted that up to 50% of patients have a preserved left ventricular ejection fraction (LVEF), while its prevalence is progressively increasing annually. Acute decompensation of CHF is understood as a rapid increase in the severity of clinical manifestations (shortness of breath, severe arterial hypoxemia, the occurrence of arterial hypotension), which caused urgent medical treatment and emergency hospitalization in a patient already suffering from CHF. Decompensation of CHF requires intensification of treatment in order to stabilize the patient's condition. Strengthening diuretic therapy in addition to standard therapy helps to reduce edematous syndrome.


Clinical Trial Description

Chronic heart failure (CHF) is a syndrome caused by a violation of the heart's ability for contraction and relaxation, which is associated with an imbalance of vasoconstrictor and vasodilating neurohormonal systems, leading to hypoperfusion of organs and systems and the appearance of such complaints and signs as shortness of breath, weakness, palpitations, increased fatigue, swelling due to fluid congestion in the body. An unfavorable prognosis, significant costs associated with excessive hospitalization of patients with this diagnosis require the development of clear criteria for the diagnosis and treatment of this condition. The variety of variants of the course of the disease, heterogeneous clinical characteristics of patients, difficulties in determining predisposing factors, unsufficient data on the pathogenetic features of the development of certain types of decompensation of CHF require an active scientific search in this direction and the development of modern clinically effective algorithms for the diagnosis and treatment of such patients The scientific hypothesis of the present study is that the use of acetazolamide in patients with decompensated HF at the hospital stage is accompanied by a significant regression of congestion compared to standard diuretic therapy (since randomization). The investigators will anticipate that appointment of acetazolamide is accompanied by a decrease in the manifestation of edema syndrome. ;
