NT-proBNP blood test

PH-ILD can put strain on your heart. NT-proBNP is a blood test that can help detect strain on the heart. Your doctor can check your NT-proBNP levels over time to see how the strain on your heart may be changing. If the numbers are higher, there is more strain on the heart; if the numbers are lower, there is less strain on the heart.

TYVASO has been shown to reduce strain on the heart

At week 16, patients who took TYVASO had less strain on the heart (NT-proBNP decreased by 15%), while patients who took placebo had more strain on the heart (NT-proBNP increased by 46%).

TYVASO has been shown to reduce the risk of PH-ILD getting worse.
