Hypertension may exaggerate pulmonary vascular reactivity to adrenergic stress; leaves open causal role and therapeutic implications.
Does adrenergic stimulation increase pulmonary vascular resistance in patients with primary hypertension compared to normotensive subjects?
Systemic hypertension is associated with exaggerated pulmonary vascular reactivity to adrenergic stimulation, suggesting a pathophysiological link between the systemic and pulmonary circulations.
Fiorentini et al. (1985) studied this question.
