Comparison of the chronic heart failure with preserved ejection fraction spread using the recommendations of the Russian Society of Cardiology and using the HFA-PEFF scale in therapy practice

High prevalence of chronic heart failure and the insufficient sensitivity and specificity of diagnostic tests for its verification forced medical community to look for а new diagnostic approaches and develop new diagnostic algorithms. Aim. The research aim was to compare the spread of chronic heart failure with preserved ejection fraction using the Recommendations of Russian Cardiological Society approved by the Scientific and Practical Council of the Ministry of Health of the Russian Federation on Chronic Heart Failure in 2024 and using the HFA-PEFF scale recommended by the consensus of the Heart Failure Association of the European Society of Cardiology. Material and methods. A single-stage study was conducted, 61 patients were examined, all patients were examined in the Private Medical Institution «Clinical Hospital Russian Railways-Medicine» in Chelyabinsk. The average age was 52.7 years. There was prevalence of males in the examined population (88.5% of the total number of examined patients). The inclusion criteria were the presence of echocardiography, electrocardiography and stress echocardiography data with an assessment of diastolic function in the patient's cards. The exclusion criteria were the presence in the diagnosis of chronic heart failure with a mildly reduced and reduced ejection fraction. All patients included in the study underwent an assessment of structural and functional disorders associated with diastolic dysfunction of the left ventricle according to the Recommendations of the Russian Cardiological Society. All patients included in the study were also validated according to the HFA-PEFF scale, recommended by the consensus of the Association for Heart Failure of the European Society of Cardiology to verify the signs of heart failure with preserved ejection fraction. Results. Diastolic dysfunction was detected in 27.8% (17) of patients according to the criteria recommended by the Russian Society of Cardiology. Due to the fact that the examined patients had no symptoms associated with heart failure, a clinical diagnosis of heart failure was not made. The echocardiographic criteria of the pre-stage of heart failure were identified in 34.4% (21) of patients according to the recommendations of the Russian Society of Cardiology. According the HFA-PEFF scale 21 (34.4%) patients were scored from 2 to 4 points, that means, that the diastolic stress test was required. Positive result of the diastolic stress test was revealed in 2 (9.5%) patients, and it made possible to diagnose heart failure with a preserved ejection fraction, according to the consensus of the Heart Failure Association of the European Society of Cardiology. Conclusion. In comparison of spread of chronic heart failure with preserved ejection fraction using the Recommendations of Russian Cardiological Society approved by the Scientific and Practical Council of the Ministry of Health of the Russian Federation on Chronic Heart Failure in 2024 and using the HFA-PEFF scale recommended by the consensus of the Heart Failure Association of the European Society of Cardiology no significant differences were obtained.
