Maintaining healthy heart function is not as easy as going for a jog each day for those suffering with pulmonary arterial hypertension (PAH). To slow damage to their heart, patients need to do all that they can, and exercise can potentially improve their quality of life.

    However, many patients have a higher chance of suffering the consequences of overexertion due to the demands of pumping blood into stiffened, large arteries and narrow small arteries, making it hard to decide on how much exercise a patient should do.
