Introduction.Chronic obstructive pulmonary disease and cardiovascular diseases (arterial hypertension, ischemic heart disease, chronic heart failure) are among the comorbid conditions that mutually aggravate each other. The addition of tuberculosis in this category of patients requires additional efforts from the doctor to improve treatment outcomes.Purpose.Тo assess the prevalence of chronic obstructive pulmonary disease, arterial hypertension, coronary heart disease and chronic heart failure in patients with newly diagnosed tuberculosis hospitalized in an anti-tuberculosis hospital.Materials and methods.We examined 462 patients with newly diagnosed tuberculosis, hospitalized in a tuberculosis dispensary, aged 17 to 88 years, the median (Me (P25; 75) age was 43.68 (32.00; 54.00) years, including 266 men (57.6%) and 196 women (42.4%) All patients underwent clinical, laboratory, instrumental examination to establish or confirm the diagnosis.Results.The incidence of chronic obstructive pulmonary disease among patients with newly diagnosed tuberculosis was 31.4%, with arterial hypertension – 12.1%, coronary heart disease – 6.1%, chronic heart failure – 6.1%. The incidence of cardiovascular pathology in the group of tuberculosis + chronic obstructive pulmonary disease was 40%, in the group of tuberculosis without chronic obstructive pulmonary disease 6%.Conclusions.The prevalence of comorbid cardiovascular pathology in patients with tuberculosis + chronic obstructive pulmonary disease is significantly higher than among patients with only tuberculosis, which requires the involvement of doctors of various specialties to manage this category of patients to prevent adverse treatment outcomes, disability and mortality.
