Loss of Lung Health from Young Adulthood and Cardiac Phenotypes in Middle Age

Abstract

Patterns of loss of lung health are associated with specific cardiovascular phenotypes in middle age. Decline in FEV1/FVC ratio is associated with underfilling of the left heart and low cardiac output. Decline in FVC with preserved FEV1/FVC ratio is associated with left ventricular hypertrophy and diastolic dysfunction. Cardiopulmonary interactions apparent with common complex heart and lung diseases evolve concurrently from early adulthood forward.
