Elevated pulmonary pressure: A novel risk marker in kidney disease?

Pulmonary hypertension is associated with adverse cardiac outcomes and death in the general population. Bolignano and colleagues studied the prevalence of higher estimated pulmonary artery systolic pressure (⩾35 mm Hg) assessed using echocardiogram among patients with stage 1-4 chronic kidney disease. They further examined the associations of higher pulmonary pressures with a composite cardiovascular outcome. These findings suggest the potential role of pulmonary arterial systolic pressure as a risk marker in those with chronic kidney disease.
