| Summary: | Study objective: to study the incidence of arrhythmias in patients with metabolic syndrome and heart failure in accordance with the severity of the functional class (1964, according to the NYNA classification).Materials and methods: The study included 90 patients with heart failure (HF) II and III functional class (FC), EF<50% and metabolic syndrome, who received outpatient and inpatient treatment at the J. Abdullaeva Scientific Researh Institute. Among the patients, 57 were with HF II (according to the NYNA classification), and 33 were with HF III functional class. The age of the patients ranged from 36 to 88 years. Of these, 27% were women, 63% were men. The patients underwent complex clinical, instrumental and laboratory examinations. Instrumental examinations included daily monitoring of the electrocardiogram by the Holter method (with CONTEC, TLC 5000), 6-minute walking test, blood ion analysis, MS indicators, and lipid spectrum research. Exclusion criteria were chronic obstructive pulmonary disease, bronchial asthma, cardiomyopathies,heart defects.Results: The incidence of ventricular premature beats (especially in an amount greater than 1000) among patients with heart failure of the III functional class (97.0%) is slightly higher than in patients of the II functional class (91.2%). However, supraventricular premature beats are more common (78.9%) in patients with functional class II heart failure than in functional class III patients (57.6%). Atrial fibrillation in patients with heart failure of functional class III (33.3%) occurs approximately 1.7 times more often than in patients of functional class II (19.3%). Almost the same frequency of occurrence of episodes of sinus rhythm and atrial fibrillation were observed. Shortterm ventricular tachycardia was recorded in 2 patients of functional class III.Conclusions: In patients with metabolic syndrome, the incidence of ventricular premature beats and atrial fibrillation correlate with the functional class of heart failure, and episodes of ventricular tachycardia are also observed. |
