Pulmonary arterial hypertension is a rare, life-threatening disorder characterized by high blood pressure in the arteries of the lungs. Current methods for diagnosing this condition can be cumbersome, expensive and not entirely reliable. Daniel Lachant, DO, Associate Director of the Pulmonary Hypertension Program at Mary Parkes Center for Asthma, Allergy and Pulmonary Care, has been awarded a grant (URMC KL2 Scholars Award) to study whether cardiac effort (the number of heart beats required for a person to walk a given distance) is a more sensitive and reliable measure to monitor patients. Dr. Lachant will also develop a remote, mask-free assessment of cardiac effort and heart rate expenditure that patients can perform in the comfort of their own homes.
