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

ABSTRACT: Cardiorespiratory fitness (as measured by peak oxygen consumption [VO_2peak]) is an independent predictor of cardiovascular disease and all-cause mortality. Limited data exist on VO_2peak following repair for an acute type A aortic dissection (ATAAD) or proximal thoracic aortic aneurysm (pTAA). This study prospectively evaluated VO_2peak, functional capacity, and health-related quality of life (HR-QOL) following open repair. Participants with a history of an ATAAD (n = 21) or pTAA (n = 43) performed cardiopulmonary exercise testing (CPX), 6-minute walk testing, and HR-QOL at 3 (early) and 15 (late) months following open repair. The median age at time of surgery was 55-years-old and 60-years-old in the ATAAD and pTAA groups, respectively. Body mass index signif
