What if a lung doctor and a pulmanery hypertension specialist says no pumanary hypertension but a cardioologist says yes you do why don't they agree.

Another opinion: It may help to get another opinion to sort out the problem.

Pulmonarhyping: Lung pressures can be measured with an echocardiogram or by placing a catheter in the pulmonary artery and measuring it directly. This is most accurate method. The echo measurements can be falsely elevated. If you had a right heart catheter procedure i would go by that reading.
