Pulmonary Hypertension in Chronic Lung Disease In proportion PH in lung disease: the underlying parenchymal remodeling causes some natural loss of overall vascular cross-sectional area Out of proportion PH in lung disease: the severity of PH is high in relation to the degree of lung parenchymal abnormalities
Pulmonary Hypertension in Chronic Lung Disease In proportion PH in lung disease: the underlying parenchymal remodeling causes some natural loss of overall vascular cross-sectional area Out of proportion PH in lung disease: the severity of PH is high in relation to the degree of lung parenchymal abnormalities severe PH in lung disease: mpap > 35 mm Hg or mpap > 25 mm Hg with low CI (<2 l/min/m 2 )
Pulmonary Hypertension in Chronic Lung Disease In proportion PH in lung disease: the underlying parenchymal remodeling causes some natural loss of overall vascular cross-sectional area Out of proportion PH in lung disease: the severity of PH is high in relation to the degree of lung parenchymal abnormalities limitation of exercise capacity due to exhausted circulatory reserve rather than an ventilatory reserve low carbon monoxide diffusion capacity
Pulmonary Hypertension in Chronic Lung Disease In proportion PH in lung disease: the underlying parenchymal remodeling causes some natural loss of overall vascular cross-sectional area Out of proportion PH in lung disease: the severity of PH is high in relation to the degree of lung parenchymal abnormalities The severe PH group : minority of chronic lung disease patients (for COPD is 1 % of the entire population)
