Overview
Pulmonary function test may be helpful in the diagnosis of interstitial lung disease as a complication of MCTD and Right heart catheterization is the standard diagnostic approach for definitive diagnosis of pulmonary hypertension as a complication of MCTD
Other Diagnostic Studies
Pulmonary function test
- Pulmonary function test may be helpful in the diagnosis of interstitial lung disease as a complication of MCTD. Findings suggestive of interstitial lung disease include:[1][2]
- DLCO values is significantly lower in the active pulmonary stage (most sensitive test for predicting the presence of fibrosing alveolitis)
- Restrictive ventilatory defect (reduction of FEV1 and total lung capacity)
Right heart catheterization
- Right heart catheterization is the standard diagnostic approach for definitive diagnosis of pulmonary hypertension as a complication of MCTD.[3]
