 At the 6 month follow up visit, subjects will undergo resting and exercise echoCBPmetabolic stress testing exactly as performed at visit 1. The co-primary endpoints will be the change in central augmentation index defined below and change in peak oxygen uptake VO2 from baseline. Secondary endpoints will include the changes in resting and exercise-induced CBP and brachial blood pressures, number of antihypertensive medications prescribed, resting and exercise change in LV systolic and diastolic function see below, changes in: cardiac output, exercise time, anaerobic threshold, minute ventilation VE over carbon dioxide produced VCO2 slope ventilatory efficiency. There will be a total of 7 visits, the first and last for exercise testing; the intervening 5 visits will be routine heart failure clinic follow up appointments.
