Pulmonary Vascular Resistance During Exercise Predicts Long-Term Outcomes in Heart Failure With Preserved Ejection Fraction
2018, Journal of Cardiac FailureCitation Excerpt :Normal pulmonary circulation is dynamically affected by both passive and active mechanisms during exercise. Passive factors include increased transmural pressure driven by input and outflow pressures (pulmonary arterial pressure and PAWP, respectively) that assist in ventilation/perfusion matching.18 Active factors include nitric oxide–mediated vasodilation, regional alveolar hypoxia, and sympathetic nervous system activation–mediated vasoconstriction, which affect recruitment, distention, and PVR during exercise.19–21
Right ventricular afterload and the role of nitric oxide metabolism in left-sided heart failure
2013, Journal of Cardiac FailureCitation Excerpt :This provokes a linear increase in mean pulmonary arterial pressure (mPAP), as a function of Q, during most of the course of exercise. Only in the beginning of exercise might this curve be somewhat curvilinear (concave to the flow axis) owing to dilation and/or recruitment of the pulmonary vasculature (Fig. 5).36,45–47 However, the slope of the curve is steeper in certain pathologies, such as PAH and heart failure with reduced (HFrEF) or preserved (HFpEF) ejection fraction.48,49
World Health Organization Pulmonary Hypertension Group 2: Pulmonary hypertension due to left heart disease in the adult - A summary statement from the Pulmonary Hypertension Council of the International Society for Heart and Lung Transplantation
2012, Journal of Heart and Lung TransplantationCitation Excerpt :In this setting, eliciting dynamic PH with exercise or attenuating PH with vasodilator exposure can be particularly useful in characterizing PH in the setting of LHD. In healthy individuals, passive distention of a compliant pulmonary circulation and active flow-mediated vasodilation allows the pulmonary vasculature to accommodate increased cardiac output during exercise, with only a modest increment in PAPs3 and a fall in PVR.78 Exercise-induced PH arises when the pulmonary vasculature is unable to accommodate increased blood flow during exercise without an abnormally high PCWP and/or PVR.79
