Implication
Recovery haemodynamics lack sensitivity for ePH/ePVH diagnosis and should not yet guide practice; leaves open optimal timing for invasive exercise testing.
Structured PICO
Does measuring pulmonary haemodynamics during recovery after maximum invasive cardiopulmonary exercise testing accurately diagnose exercise pulmonary hypertension in patients with unexplained exertional intolerance?
P
Population
95 patients evaluated for unexplained exertional intolerance, comprising exercise pulmonary hypertension (ePH; n=36), exercise pulmonary venous hypertension (ePVH; n=28), and age-matched controls (n=31).
I
Intervention
Directly measured pulmonary haemodynamics during 2-min recovery after maximum invasive cardiopulmonary exercise testing
C
Comparator
Age-matched controls (n=31)
O
Outcome
Sensitivity of pulmonary hypertension-related haemodynamic measurements during recovery for ePH and ePVH diagnosissurrogate
Measuring pulmonary haemodynamics during the recovery period after exercise is not a sensitive method for diagnosing exercise pulmonary hypertension due to the rapid decay of pressures.
