Question: The aim was to develop the method for evaluation of blood pressure in pulmonary artery based on impedance cardiogram (ICG) and test it by two-dimentional transtoracal cardioechoscopy (2DECHO) data.

Method Used: The records of tetra-polar ICG and three lead ECG were obtained and analysed by using hardware and software developed in our institution. The assessment of systolic pressure in pulmonary artery (SPPA) was performed by modified Burstin’s equation: SPPA=702 x PEP–52,8, where PEP - pre-ejection period in milliseconds. The population consisted of 109 patients: 61 patient with clinically and 2DECHO confirmed hypertension of pulmonary artery (PAH), conditioned by cardiac pathology (chronic disfunction of left ventricle, occlusion of pulmonary veins, congenital and congestive defects of valves) or/and pulmonary pathology (lung tumours, chronic obstructive pulmonary disease, bronchial asthma, thrombosis of leg veins); 53 patients (control group) with cardiac or/and pulmonary pathology, but without PAH (excluded clinically and 2DECHO).

Results: SPPA assessed by using two methods –2DECHO and ICG, and especially significant Spearman’s coefficient of correlation (r=0,836, p=0,0001) between performance of these methods have been received. Distributions of SPPA values, measured by ICG method well coincided with such, obtained by 2DECHO method (p=0,915). The following equation of regression was constructed: SPPA (obtained by 2DECHO) = 1,107 x SPPA (obtained by ICG) – 2,856.

Conclusion: The received results permits to suppose, that ICG method performs the measurement of SPPA with ample efficacy, as compared with such of basic 2DECHO method, and ICG could be used for detecting patients with hypertension of pulmonary artery.
