Evaluation of Pulmonary Artery Pressure in the Aged Population

Abstract

ging is a major risk factor for the most important age-related diseases including coronary, peripheral, and cerebrovascular artery disease. Pulmonary hypertension is a substantial global health issue. All age groups are affected with rapidly growing importance in elderly people, particularly in countries with ageing populations. Aim of the study was to evaluate the effect of aging on resting pulmonary artery systolic pressure non-invasively using TTE. We recruited 200 elderly patients referred for echocardiographic evaluation at Heliopolis and Ain Shams University Hospitals in the period from August 2017 to February 2018 .After a detailed history, all patients were assessed clinically followed by M-Mode and 2D echocardiographic assessment, pulsed and continuous wave Doppler for routine examination. RVSP was calculated from the peak tricuspid regurgitate jet velocity (V) using the modified Bernoulli equation (RVSP = 4V2 + RAP), with the mean right atrial pressure (RAP) estimated to be 10 mmHg. While Mean PA pressure = 79 (0.45 x AT), where acceleration time (AT) being measured from PW Doppler on pulmonary valve in short axis aortic level.
