Цель
To determine the clinical and echocardiographic features of rheumatic heart disease (RHD) com-plicated by atrial fibrillation (AF).
Материал и методы
A retrospective analysis was conducted on 156 medical records of patients aged over 18 years with RHD who underwent inpatient treatment at the «Republican Clinical Cardiolo-gy Center» under the Ministry of Health and Social Protection of the Republic of Tajikistan from 2022 to 2024. The diagnosis of RHD was established based on clinical data, electrocardiography (ECG), and echocardiography (EchoCG). AF was diagnosed via ECG as an irregular heart rhythm without P waves but with f waves. EchoCG parameters evaluated included valve involvement, sizes of the left atrium (LA) and left ventricle (LV), and LV function.
Результаты
AF was detected in 75 (48.1%) out of 156 RHD patients. The prevalence of AF was higher among women (77.3%) compared to men (22.7%). The mitral valve (MV) was most frequently affected (86.6%), followed by the aortic valve (22.7%). AF incidence was significantly higher in predominant mitral stenosis (MS) (66.6%) compared to mitral regurgitation (MR) (17.3%). For MS with a mitral valve area (MVA) <1.5 cm², the prevalence of AF was 52.0%. Combined involvement of the MV and aortic valve was observed in 17.3% of patients. Enlargement of the LA (>40 mm) was noted in 97.4% of patients
Заключение
AF is a frequent arrhythmic complication in RHD. Its prevalence is higher in women and increases with advancing age, LA size, and severity of MS.
