Heart failure requiring hospitalization in patients after cardiac surgery for valvular heart disease

The aim – to determine the factors associated with the frequency of hospitalizations for decompensation of heart failure (HF) after cardiac surgery in patients with valvular heart disease. Materials and methods. 235 patients who underwent cardiac surgery for valvular heart disease were examined. During the period from 2014 to 2017, a part of patients (129 people) had no hospitalizations, while 106 people were on inpatient treatment from 1 to 10 times, on average 2.78±1.95. The complex of examination of patients along with physical examination included electrocardiography, echocardiography. Results and discussion. During dynamic observation for 2 years in the group of patients without hospitalization, a progressive statistically significant decrease in the size of the left atrium (LA) and left ventricle (LV) as well as an increase in LV contractility were noted, while in the group of patients after hospitalization such changes were not observed. The dimensions of the chambers of the heart remained practically unchanged for 2 years. Thus, it can be concluded that the more severe course of heart failure after prosthetics of heart valves is accompanied by the absence of reverse remodeling of the heart chambers. Predictors of hospitalizations for HF are the presence of diabetes mellitus, hypertension and permanent form of atrial fibrillation. Conclusions. The probability of progression of heart failure in patients after cardiosurgical intervention for valvular heart pathology is not affected by sex, age, type of lesion of the valve, etiology of valve damage, indicators of echocardiography. Predictors of hospitalizations for heart faiure in the long-term postoperative period are the presence of diabetes, AF, and AH. The more severe course of heart failure after prosthetics of heart valves is accompanied by the absence of reverse remodeling of the heart chambers.
