Could an echocardiogram detect pulmonary disease/pulmonary hypertension?

Pulmonary HTN: Echo can detect pulmonary hypertension, but no signs of it on echo does not necessarily rule it out. Right heart catheterization is the most accurate way to diagnose it. There are recent studies suggesting the inaccuracy of echocardiograms on diagnosing pulmonary htn.

Yes: Echo or cardiac ultrasound is a good non invasive way to detect pulm htn.

ECHO for PH: Pulmonary hypertension (ph) is often first detected by echocardiogram (echo) which estimates the pulmonary artery systolic pressure. The diagnosis is confirmed by right heart catheterization which measures mean pulmonary artery pressure and resistance.
