BACKGROUND: The influence of b-blockers on heart rate recovery (HRR) and @entity1168 ( @entity1168 ) during Phase I cardiac rehabilitation (CR) for @entity1 with a recent episode of @entity583 ( @entity583 ) is not clear. METHODS: From October 2009 to July 2011, 105 @entity1 with a recent episode of @entity583 who received a successful percutaneous coronary intervention were recruited into this study. Before entering Phase II CR, each @entity1 underwent a cardiopulmonary exercise test (CPET), where @entity1168 was assessed every minute and related parameters were recorded. RESULTS: The @entity1 entering CR had relatively low mean peak @entity26 consumption (VO2max). However, the peak heart rate and VO2max were lower in those taking b-blockers. The @entity1168 value at the @entity1576 ( @entity1576 ) was significantly higher (12.7      1.7) in @entity1 who were taking b-blockers relative to those who were not (11.5      1.4). The HRR value was lower (12.5      8.8) in @entity1 who were taking b-blockers relative to those who were not (17.0      9.1). CONCLUSION: These findings suggest that use of b-blockers increased the @entity1168 value at the @entity1576 . In addition, HRR was attenuated by b-blockers. In @entity1 who do not undergo CPET, the use of b-blockers should be taken into consideration when using @entity1168 for the initial exercise prescription to determine training intensity.
