Pulmonary artery hypertension (PH), associated with increased left ventricular (LV) diastolic pressure and pulmonary vasoconstriction, is frequently observed in heart failure (HF), where it holds prognostic significance. We hypothesized that Cheyne-Stokes respiration (CSR) may contribute to increased pulmonary arterartery pressure (PAP) and right ventricular (RV) remodeling in HF, via hypoxia/hypercapnia cycles and adrenergic activation by the chemoreflex stimulation.

Abstract
Pulmonary artery hypertension (PH), associated with increased left ventricular (LV) diastolic pressure and pulmonary vasoconstriction, is frequently observed in heart failure (HF), where it holds prognostic significance. We hypothesized that Cheyne-Stokes respiration (CSR) may contribute to increased pulmonary arterartery pressure (PAP) and right ventricular (RV) remodeling in HF, via hypoxia/hypercapnia cycles and adrenergic activation by the chemoreflex stimulation.File in questo prodotto:
