Simple breathing workout may ease rare lung condition

This study tests whether six weeks of special breathing exercises (called inspiratory muscle strength training) can improve heart and lung function in people with pulmonary hypertension, a condition where high blood pressure strains the heart and lungs. Four adults already scheduled for routine heart-lung tests will do the exercises and then repeat the tests to see if there is improvement. The goal is to learn if this simple, drug-free approach can help manage the disease.
