The management of patients with cardiovascular pathology and comorbid obstructive pulmonary diseases seems to be an urgent problem against the background of their widespread prevalence among the adult population. According to the latest recommendations of GOLD 2017, it is not possible to diagnose COPD and to select options for pharmacotherapy without assessing the symptoms. Evaluation of symptoms in patients with cardiorespiratory pathology is a key element in the diagnosis of both respiratory and cardiovascular deseases. It is important to conduct differential diagnosis of both nosologies for reliable evaluation of the results of standardized respiratory questionnaires. Many respiratory questionnaires have been developed now; some of them have been validated and recommended for use in clinical practice in patients with COPD and asthma. However, their sensitivity and specificity are different, these questionnaires can`t be used interchangeably. In some cases, a decrease in the informative value of standardized respiratory questionnaires was revealed in patients with comorbid cardiovascular and obstructive pulmonary diseases. There are extremely few scientific works, that assess the same aspects of this problem. In connection with this, the development of specialized questionnaires for patients with comorbid cardiovascular and obstructive pulmonary pathology is relevant.

Objective: To determine the frequency of detection of chronic obstructive pulmonary disease (COPD) and Asthma in patients who are admitted to specialized cardiological hospital with arterial hypertension (AH), including AH with chronic heart failure (CHF), coronary heart disease (CHD), cardiac arrhythmias. Analyze the possibility of early diagnosis and the validity of the modified questionnaire for screening risk factors and symptoms of broncho-obstructive pathology in patients with arterial hypertension.Materials and methods: The sample (n = 1000) consisting of individuals over the age of 18 who continuously arrive for inpatient treatment at the admission department of the National Medical Research Center of Cardiology with arterial hypertension, incl. AH with CHF, IHD and arrhythmias in the period from 2018 to 2019. Active identification of broncho-obstructive pathology among all persons was carried out (history taking, complaints), analysis of medical documents provided by patients (conclusions from outpatient and reference cards of the patient), screening of risk factors and symptoms of broncho-obstructive pathology (a modified questionnaire was used), external respiration function was assessed (computer spirometry), filled out the specialized respiratory questionnaires (CAT, mMRC, ACT).Results: The undiagnosed broncho-obstructive diseases was demonstrated against the background of their high occurrence in patients with hypertension, incl. CHF, coronary artery disease, NRS entering a specialized cardiological hospital. The study established the most likely predictors of airway obstruction in patients with hypertension, which signal the need to assess the function of external respiration (computed spirometry).Conclusions: The development and validation of a modified questionnaire makes it possible to identify specific symptoms and risk factors for bronchoobstructive diseases against the backdrop of their high prevalencre among patients who are admitted to cardiology hospital with arterial hypertension.
