Patients at high or intermediate probability of having pulmonary hypertension (PH, n=79) were defined, for the purposes of this study, as having PH on echocardiogram in combination with secondary signs of PH.2Patients were characterised by CT, and adjusted regression analysis identified that both large and central opacities were predictive of PH, and the authors assert that the mechanical obstruction to the proximal pulmonary vasculature may be aetiologically important.These findings further support the view that echocardiographic features of even mild elevation of PA pressure are associated with a worse prognosis,3 with those defined as having an intermediate or high probability of PH having a survival of … ER -
