Is there an entity called “ Isolated ” systolic pulmonary arterial hypertension ?

What is the incidence of Isolated systolic pulmonary arterial hypertension (ISPAH) and its Implication? We attempted to answer this question and found some interesting answers. It was published in the Indian heart journal  December 2007 Abstract issue. More than a decade gone. I think this issue is still largely misunderstood. Fellows may pursue this. One more parameter that can be explored is pulmonary artery pulse pressure and effect on progressive pulmonary vascular disease and PVR. Mean while  PAH definition and classification has changed many times, ISPAH definitely requires a place in the new scheme of things. The abstract ISOLATED SYSTOLIC PULMONARY ARTERIAL HYPERTENSION S.Venkatesan ,G.Gnanavelu,V.Jaganathan , Madras Medical College. Chennai Pulmonary circulation is a classical example of a low-pressure low impedance circulation. It is generally presumed high output states generally do not increase the systolic blood pressure in the pulmonary circulation. In systemic circulation, there can be divergence of systolic and diastolic blood pressure depending upon the cardiac output and peripheral vascular resistance. This has resulted in separate clinical entity -Isolated systolic hypertension.(ISH). It has been our observation many of the patients with PAH during echocardiographic and cath study were found to have an elevation of systolic pulmonary artery pressure(PAP) with normal diastolic PAP . In this context, this study was undertaken to specifically identify whethe...
