Portrait of a patient with chronic heart failure with preserved ejection fraction and assessment of survival considering comorbid pathology

Introduction. Chronic heart failure (CHF) is a clinical syndrome that is a widespread complication of cardiovascular diseases. The majority of patients with CHF are individuals with a preserved left ventricular ejection fraction (LVEF ≥ 50 %). The number of such patients is increasing every year, while there is no effective drug therapy for this disease. Objective. To create a portrait of a patient with CHF and analyze the 10-year survival rates on the Charlson Comorbidity Index scale in a cohort of patients, considering gender and age characteristics. Materials and methods. Patients with CHF participated in the study. Demographic, anamnestic, and laboratory instrumental data were considered. The 10-year survival rate was assessed using the Charlson Comorbidity Index scale. Results. The average age of the subjects was 62 ± 26 years. Among the pathologies of the cardiovascular system, hypertension prevailed — 274 people (100 %), angina pectoris — 184 people (67 %), and atrial fibrillation (AF) — 100 people (36 %). Among the studied 14 people. (5 % of patients) had a history of chronic obstructive pulmonary disease (COPD), 8 people (3 %) had bronchial asthma (BA). 88 subjects (33 %) suffered a cardiovascular catastrophe. Among all the studies, the 10-year survival rate on the Charlson Comorbidity Index scale of less than 50 % was detected in 174 people (63.5 %), among whom 106 women predominated (39 %). Conclusion. Portrait of a typical patient with CHF: male or female patient aged 60–69 years. Of the concomitant pathologies, most often those who are overweight / obese, hypertension, angina pectoris, atherosclerosis, AF, diabetes mellitus, who have had a history of myocardial infarction and/or stroke/transient ischemic attack. Older women (from 60 to 74 years old) are more likely to have a survival index of less than 50 % on the Charlson Comorbidity Index scale.
