Cardiac Rehabilitation After Heart Valve Surgery: COMPARISON WITH CORONARY ARTERY BYPASS GRAFT XXXX .

@entity1 @entity340 @entity26
PURPOSE: Coronary artery bypass graft (CABG) surgery @entity1 participating in cardiac rehabilitation (CR) experience improvements in aerobic fitness, but there has been little study of outcomes for @entity340 ( @entity340 ) surgical @entity1 . The primary aims of this study were to evaluate baseline peak aerobic capacity for @entity340 @entity1 participating in CR and to compare outcomes between @entity340 and CABG @entity1 . METHODS: Five hundred seventy-six consecutive @entity1 who underwent @entity340 surgery (n = 125), @entity340 plus CABG surgery (n = 57), or CABG surgery (n = 394), all with classic sternotomy and enrolled in CR, were prospectively studied. Changes in outcomes were assessed for individuals who completed CR (n = 313). RESULTS: @entity340 @entity1 were significantly older and had a greater percentage of females than the CABG-only group. Combining @entity340 and @entity340 + CABG groups, @entity340 included 134 mitral, 39 aortic, and 8 combined abnormalities (mitral and aortic). For the entire cohort, the mean number of CR exercise sessions attended was 23.6    11.7. Peak @entity26 uptake ((Equation is included in full-text article.)) increased 19.5% from 17.4    4.4 to 20.8    5.5 mLO2  kg  min (P < .0001). Improvement in peak (Equation is included in full-text article.)with CR exercise training was similar between the 3 groups of @entity1 . Within the group of @entity1 who had @entity340 surgery, percentage change in peak (Equation is included in full-text article.)was not significantly different between the 3 types of @entity340 (ie, mitral [19.2%], aortic [24.4%], and mitral + aortic [21.9%]). CONCLUSIONS: @entity340 surgery @entity1 achieve similar improvement in aerobic fitness from participating in CR exercise training as individuals who had CABG. The observed improvements in aerobic fitness are similar, regardless of the type of @entity340 or whether CABG was performed concurrently.
