The blood-groove and the biomechanics of the pulmonary artery at patients with COLD I and II stages

Abstract

The blood-groove in the pulmonary artery was studied by the method of the Echocardiography in the impulse doppler mode and the biomechanic by the method of the automated analysis rheogramma of the pulmonary artery at 23 patient with COLD l stage (GOLD, 2006) and at 35 patient with COLD ll stage. The violation of haemodynamics were realised by increase in high-speed parametres at patients with COLD l stage and lowering at patients COLD ll stage. The average pressure in the pulmonary artery authentically exceeded the normal amounts at patient both groups. The biomechanics violations were characterised hypodynamy in the systole of the pulmonary artery
