摘要:

Purpose:Pulmonary rehabilitation programs consistently have improved exercise capacity, quality of life, and symptoms over the past decade. Although training has been shown to be an essential component of the rehabilitation program, individual patients do not always benefit to the same extent. The present study was designed to investigate which patients were achieving significant benefit of exercise training.Methods:Forty-nine stable outpatients with moderate to severe COPD (FEV137 (15)%pred) were evaluated before and after 12 weeks of exercise training (3 times per week). Responders in exercise capacity were defined as having 15% increase in maximal workload and/or 25% increase in walking distance, while responders in quality of life showed an improvement of at least 10 points on the chronic respiratory disease questionnaire. With multivariate discriminant analysis, responders were distinguished from nonresponders based upon their initial characteristics.Results:Thirty-two patients were responders in terms of improved exercise capacity. Ventilatory reserve (VE/MVV), inspiratory muscle strength (Plmax), and peripheral muscle strength (handgrip force and quadriceps force) were significant predictors of the training response (P<0.05) (accuracy 80%P<0.001). Although the explained variance was modest, patients that were clearly ventilatory limited and had normal skeletal muscle strength were not likely to benefit from exercise training in terms of exercise capacity. No physiologic variables predicted whether a patient would increase quality of life after exercise training.Conclusion:Patients with reduced exercise capacity who experience less ventilatory limitation to exercise and more reduced respiratory and peripheral muscle strength are more likely to improve with exercise training. Improvements in quality of life after exercise training were significant but remained unpredictable with variables included in the present trial.

摘要:

Purpose:Household tasks are highly salient physical activities for women. Inability to perform household tasks may serve as an important marker of limitations imposed by cardiac symptoms. The purpose of this study was to examine the impact of cardiac symptoms on perceived ability to perform household tasks in women with coronary artery disease and to examine relationships among age, whether the woman lived alone, ability to perform household tasks, and cardiac-related quality of life.Methods:Forty-one women with confirmed diagnosis of coronary artery disease and a mean age of 66 years (SD 12 years) were interviewed about the impact of their cardiac symptoms and perceived ability to perform household tasks (Household Activities Scale) and cardiac-related quality of life (Seattle Angina Questionnaire). The women were primarily white (89.4%) and retired (65.9%). Forty-six percent were married, and 26.8% lived alone.Results:"Washing dishes" (51.3%) was the only task a majority of the sample could perform without limitation. Household tasks most commonly reported as no longer performed included carrying laundry (24.4%), vacuuming (30.0%), and scrubbing the floor (51.2%). The task most commonly modified because of cardiac symptoms was changing bed linens (60%). Of the 14 household tasks, women performed a mean of 3.39 (SD 3.36) activities without difficulty. Total number of household activities performed without difficulty was associated with better quality of life in the area of exertional capacity (r=0.50,P=0.001). Women who lived alone reported greater perceived ability to perform household tasks than women who did not live alone (r=0.31,P=0.05). Age was not significantly associated with perceived household task performance (r=−0.22,P=0.17).Conclusion:Women with coronary artery disease (CAD) perceived cardiac symptoms as disrupting their ability to perform household tasks. Future research is needed to determine the independent impact of cardiac symptoms on functional limitations, especially in older women with heart disease, and whether changes in ability to perform household tasks could be a marker for coronary artery disease progression in women.

摘要:

Background:This study examines the influence of gender on the healthcare provider's secondary prevention instruction and cardiac rehabilitation (CR) referral after coronary revascularization procedures such as balloon angioplasty/coronary stenting and coronary bypass surgery (CABG). Cardiac rehabilitation decreases mortality and morbidity, yet only a small percentage of women and men are referred to these programs. The patient population of our university-affiliated CR program consisted of 88% men and 12% women.Methods:In a matched case observational study, 80 patients (40 men, 40 women) who had undergone coronary revascularization procedures between 1997 and 1998 completed a questionnaire on secondary prevention instruction and written referral to CR programs. Patients were matched for age and coronary revascularization procedure.Results:Women were less likely to be instructed on secondary prevention strategies and CR or referred to CR as compared to men despite being matched for age and undergoing the same procedure. The data demonstrate a gender difference in hospital teaching and referral information for CR after revascularization (P<0.001). Being a woman was associated with a decreased likelihood of receiving a physician referral to CR after revascularization (P<0.001).Conclusion:The instruction of patients concerning secondary prevention and CR postrevascularization procedures is poor. Within that group, women were far less likely to have CR discussed or referrals made by healthcare professionals. This study demonstrates the need for education initiatives of all healthcare providers on the comprehensive nature and benefits of CR in the secondary prevention of cardiovascular disease, with a particular emphasis on women.

摘要:

Purpose:Despite the documented benefits of participating in rehabilitation programs, access to cardiac rehabilitation is limited for a large number of people with coronary artery disease (CAD). There is potential to increase participation in exercise training if home-based exercise were a viable option.Methods:We conducted a retrospective database review of 1,042 patients who took part in exercise rehabilitation following coronary artery bypass graft surgery (CABGS) between 1992 and 1998. Of these, 713 patients took part in supervised exercise, and 329 were in an unsupervised, home-based group. All exercise protocols were based upon American College of Sports Medicine guidelines, and patients in both groups received exercise prescriptions that were similar in intensity, frequency, and duration.Results:There were no differences between groups at baseline. Following 6 months of exercise training, there were substantial improvements in peak VO2, peak workload, and peak MET levels in both the supervised and unsupervised groups (P<0.0001). Patients in the supervised group had significant improvements in both LDL and HDL-cholesterol, whereas the home-based group showed improvement in HDL-cholesterol only. When analyzed by sex, men performed better than women for all measures of exercise capacity; however, women in both groups showed approximate 20% improvements (P<0.05) in exercise capacity as well as improvements in HDL-cholesterol.Conclusion:Stable post CABGS patients who receive a detailed exercise prescription to follow at home do as well as those in supervised rehabilitation.

摘要:

Background:Quality of life (QOL) is an important health-related outcome measure in patients with cardiovascular disease. The North Carolina Cardiopulmonary Rehabilitation Association (NCCRA) is a coalition of 72 state-certified, multidisciplinary cardiac rehabilitation (CR) programs. In 1997, the NCCRA Executive Board and Research Committee agreed to collect ongoing data to assess QOL changes following CR participation using the Ferrans & Powers QOL Index Cardiac Version III. The purpose of this study was to determine if changes were present in QOL scores after 12 weeks of CR in men and women from multiple outpatient centers.Methods:Data were analyzed from 420 patients from 19 Phase II early outpatient CR programs who completed the QOL index survey within the first week of program entry and upon discharge. The four QOL index domains measured were health/function, psychological/spiritual status, socioeconomic status, and family interaction. Overall QOL was tabulated as the aggregate score from the four domains. Each domain, as well as overall QOL, was compared pre- and post-CR participation with a repeated measures analysis of variance.Results:Across programs, statistically significant improvements in QOL indices were observed following 12 weeks of CR in each of the four domains and on the overall score in all patients. Men reported greater CR entry and discharge scores than women on the health/function, family interaction, and overall scores. Women showed a greater positive change in scores than men on the socioeconomic, family interaction, and overall scores.Conclusions:Patients who participated in Phase II multidisciplinary North Carolina CR programs and completed the protocol improved QOL parameters. While men had higher physical function and overall QOL scores both pre- and post-CR, women showed greater improvements in overall scores, as well as in family and socioeconomic parameters. These findings suggest that North Carolina CR patients experience a positive change in QOL following short-term participation in CR. Further study with a larger number of patients benchmarked with programs from other regions with comparisons to patients who do not participate in formalized CR programs is indicated from this investigation.
