摘要:

Background.Rehabilitation is an important part of the treatment of patients with ischemic heart disease. Therefore, many patients undergoing coronary artery bypass surgery (CABS) also participate in cardiac rehabilitation programs. This study was conducted to investigate whether rehabilitation influences quality of life and work status after CABS.Methods.Consecutive patients undergoing elective CABS were randomly assigned to a rehabilitation group (R, N = 119) and a hospital-treatment group (H, N = 109). All patients received usual medical care. Group R participated in a rehabilitation program based on exercise and counseling. The follow-up time was 5 years. The measured domains of health-related quality of life were heart symptoms, functional class, exercise capacity, use of medication, depression, the patients' perception of health, and overall life situation. The Nottingham Health Profile as a measure of perceived distress was used.Results.Symptoms, use of medication, exercise capacity, and depression scores did not differ between groups R and H. Five years after the CABS, the patients in group R reported less restriction in physical mobility on the Notthingham Health Profile than patients in group H (P = 0.005), and more patients in group R than in group H perceived their health (P = 0.03) and overall life situation (P = 0.02) as good. The increase in the proportion of subjects working was higher in group R than group H at 3 years after the CABS (P = 0.02), but not at other follow-up times.Conclusion.A cardiac rehabilitation program in conjunction with usual medical care after CABS may induce a perception of improved health. The influence on return to work is limited.

摘要:

Purpose:Ratings of perceived exertion (RPE) are widely used for monitoring individuals during graded exercise testing. Studies of the reliability of RPEs across various exercise conditions have produced mixed results. The purpose of this study was to assess the reliability of RPEs during graded exercise testing by comparing the perceptual-physiological relationship between the Bruce and Balke treadmill protocols throughout a broad range of relative exercise intensities.Methods:Thirty-eight middle-aged men and women completed two maximal treadmill graded exercise testing separated by 48 hours. Test order was randomly assigned. RPEs were compared across protocols and between gender at selected exercise intensities using a series of two-way analysis of variances with repeated measures.Results:A comparison of RPEs (Borg 15-point scale) during the graded exercise testing revealed significant protocol and gender differences at 40%, 60% and 80% of maximal heart rate reserve. RPEs were significantly higher during the Balke protocol compared to the Bruce at each intensity (40% = 9.5 ± 2.0 vs. 8.3 ± 1.6; 60% = 12.7 ± 2.4 vs. 11.1 ± 2.3; 80% = 15.7 ± 2.2 vs. 14.1 ± 2.0). In addition, men rated each intensity significantly higher than the women (P < 0.05).Conclusions:The results from the present study confirm that the perceptual-physiological relationship observed during graded exercise testing varies as a function of the treadmill protocol employed and that these differences extend throughout the exercise training intensity range (40-80% of maximal heart rate reserve) recommended for healthy adults. The perceptual differences between the protocols could not be accounted for by any of the physiological measures assessed within the study. These results have implications when using RPEs from exercise testing for exercise prescription purposes.

摘要:

Purpose.Physical activity is an important variable to measure in patients with peripheral arterial occlusive disease (PAOD) because of its relationship to cardiovascular disease morbidity and mortality. The purposes of this study were to (1) determine the reliability of measures of daily physical activity in PAOD participants using an accelerometer and a pedometer; and (2) assess the validity of both instruments by comparing them against validated physical activity questionnaires.Methods.Forty-three patients with PAOD with a resting ankle/brachial index of 0.63 ± 0.19 were monitored for 2 consecutive weekdays with an accelerometer and pedometer worn on each hip. The 48-hour monitoring period was repeated approximately 1 week later.Results.The daily physical activity values obtained from the accelerometer were similar between the two testing periods, 352 ± 248 kcal/day vs. 337 ± 199 kcal/day; P = 0.61, with a reliability coefficient of r = 0.84. The steps obtained from the pedometer during each 2-day period also were similar, 4615 ± 2839 steps/day vs. 4498 ± 2768 steps/day; P = 0.75, with a reliability coefficient of r = 0.86. The physical activity values from the accelerometer moderately correlated with the Minnesota Leisure Time Physical Activity Questionnaire, r = 0.33; P < 0.01, and the NASA/Johnson Space Center Physical Activity Scale, r = 0.44; P < 0.001. Similarly, the relationship between the steps obtained from the pedometer and physical activity values from the Minnesota Leisure Time Physical Activity and NASA/Johnson Space Center Physical Activity Scale questionnaires were significant, r = 0.46 and r = 0.51; P < 0.001, respectively.Conclusion.These findings indicate that an accelerometer and pedometer are two instruments that reliably estimate the physical activity levels of patients with PAOD over 2 consecutive days. Furthermore, the activity monitors are moderately associated with validated physical activity questionnaires, suggesting that activity monitoring measures a different component of activities in patients with PAOD with intermittent claudication.
