Cardiorespiratory Fitness After Open Repair for Acute Type A Aortic Dissection - A Prospective Study.

Cardiorespiratory fitness (as measured by peak oxygen consumption [VO]) is an independent predictor of cardiovascular disease and all-cause mortality. Limited data exist on VO following repair for an acute type A aortic dissection (ATAAD) or proximal thoracic aortic aneurysm (pTAA). This study prospectively evaluated VO, functional capacity, and health-related quality of life (HR-QOL) following open repair.
