Evaluation of Right-Ventricular Function by Doppler Echocardiography in Patients with Chronic Respiratory Failure
Why the study?
Does a new Doppler index combining systolic and diastolic function correlate with systolic pulmonary arterial pressure in patients with chronic respiratory failure?
Population
31 patients with pulmonary tuberculosis sequelae who had received home oxygen therapy during the preceding 6…

Implication
Index may indicate right-ventricular function independent of afterload; leaves open clinical utility in chronic respiratory failure.
Structured PICO
Does a new Doppler index combining systolic and diastolic function correlate with systolic pulmonary arterial pressure in patients with chronic respiratory failure?
P
Population
31 patients (16 men, 15 women; mean age 65.8 +/- 7.12 years) with pulmonary tuberculosis sequelae who had received home oxygen therapy during the preceding 6 or more months.
I
Intervention
Evaluation of right-ventricular function using a new Doppler index combining systolic and diastolic function.
O
Outcome
Correlation between the new Doppler index and systolic pulmonary arterial pressure.surrogate
A new Doppler index combining systolic and diastolic function allows for the evaluation of right-ventricular function independent of right-ventricular afterload in patients with chronic respiratory failure.
