Performing Two 6MWTs in Pulmonary Hypertension Minimizes "Learning Effect"
More than half of participants in the initial assessment were able to walk farther in the second 6MWT vs the first.
Preterm infants who need mechanical ventilation at day 7 and early echocardiographic evidence of pulmonary vascular disease are strong risk factors for late respiratory disease.
At follow-up, the 6-minute walk distance, cardiac index, stroke volume index, and other hemodynamic variables were independently associated with transplant-free survival in patients with systemic sclerosis-associated pulmonary hypertension.
In some patients at risk for pulmonary hypertension, left ventricular end diastolic pressure measurement with standard right heart catheterization should be used.
