The validation of the questionnaire for the early detection of pulmonary arterial hypertension and chronic thromboembolic pulmonary hypertension

The objective: to identify pathognomonic symptoms and signs of different groups of pulmonary hypertension (PH), analyze the possibility of early diagnosis of patients with PH and the validity of the questionnaire.Material and methods. The questionnaire consists of 6 sections: clinical symptoms, physical examination, anamnestic information; diseases associated with PH; signs of pulmonary arterial hypertension (PAH) according to electrocardiography, chest radiography, echocardiography. All sections of the questionnaire were filled by physician. Was held an analysis of clinical symptoms, medical history, physical examination, methods of instrumental examination of 81 patients with idiopathic PH in comparison with 29 patients with PAH due to congenital heart defects - PAH-CHD, 36 patients chronic thromboembolic PH - CTEPH and the control group - 48 patients with essential hypertension. In addition, the validity of the questionnaire was evaluated: structural, the criterion and discriminant validity.Results. The leading complaint in IPAH patients was syncope; in patients with PAH-CHD the most often detected signs were cyanosis and accentuated pulmonary component of 2d heart sound; in patients with CTEPH - cough, they had a history of venous thrombosis of the lower limbs and the debut of the disease has been associated with pregnancy.Conclusion. Development and validation of a screening questionnaire allows to improve approaches to early detection of various forms of PH, allows identify specific symptoms that more typical of definite forms of PH.
