Study provides new insights on exercise limitations in patients with ventricular assist devices

Why don't patients with ventricular assist devices get better improvement in exercise tolerance? Increases in key internal heart pressures appear to be the answer, reports a study in the ASAIO Journal, official journal of ASAIO. The journal is published in the Lippincott portfolio by Wolters Kluwer.
