Abstract

Comorbidity between cardiovascular diseases and other somatic conditions plays a significant role in the prognosis of individuals with coronary heart disease (CHD). The prognostic significance of comorbidity between these conditions varies depending on the effectiveness of treatment.

The aim of the study is to analyze the comorbidity of CHD with other cardiovascular and somatic diseases, taking into account age and gender characteristics.

The clinical and open-label study included men and women aged 40 years and older, hospitalized at the National Medical Research Center for for Therapy and Preventive Medicine with a diagnosis of CHD. The study included 1,484 patients with CHD, divided into two groups: those with and without cardiac arrhythmias (CA). The primary source of information was medical records from the center's archive. Along with sociodemographic indicators, behavioral and biological risk factors for chronic noncommunicable diseases, the presence of CVD and other somatic conditions was analyzed.

Results.

Among patients with CHD without CA, the largest number were those aged 60-69 years, followed by those over 70 years old. Among individuals with CHD and CA, the largest number of patients were over 70 years of age, followed by those aged 60-69 years. Approximately 90% of patients with CHD, regardless of gender, have comorbidity with other cardiovascular and somatic diseases. Individuals with CHD without CA are more likely to have 2-3 additional CVD, while those with CHD and CA are more likely to have 3-4 additional CVD. Among additional cardiovascular diseases, hypertension and chronic heart failure are the most common. Chronic kidney disease is more common in individuals with CHD  and CA compared to those without CA (p<0.001), while the incidence of bronchopulmonary and gastrointestinal diseases was comparable between the groups.

Conclusion.

When developing secondary prevention strategies for CHD to improve quality of life and life expectancy, it is important to consider the comorbidity of cardiovascular diseases and other somatic diseases.
