OBJECTIVE: To evaluate the effects of cardiac rehabilitation on the recovery of heart rate over 1 min after peak exercise of patients who received coronary artery bypass graft (CABG) surgery. DESIGN: Thirty subjects who received CABG surgery were randomly assigned to enter or not enter a cardiac rehabilitation exercise programme (cardiac rehabilitation n = 15; control group n = 15). SETTING: Outpatient cardiac rehabilitation centre in a national medical hospital. INTERVENTIONS: Patients assigned to the cardiac rehabilitation group received 36 sessions of the exercise programme, three times a week, with the intensity designed to achieve an individual 60-85% peak heart rate in cardiopulmonary exercise test. Patients assigned to the control group did not get further advice about a specific exercise programme. MAIN OUTCOME MEASURES: Resting heart rate and recovery of heart rate over 1 min after a peak exercise test at discharge and three months later were collected. The heart rates were analysed with computer-recorded electrocardiogram. RESULTS: At follow-up, the 15 patients in the cardiac rehabilitation group had a significantly lower resting heart rate (77.46+/-9.49 versus 92.31+/-10.18 bpm; p<0.001) and a significantly higher recovery of heart rate over 1 min (16.38+/-6.32 versus 11.38+4.81 bpm; p = 0.03) compared with the control group. There were also significant reductions in resting heart rates (cardiac rehabilitation p < 0.001; control p = 0.05) and improvements in recovery on heart rate over 1 min (cardiac rehabilitation p < 0.001; control p = 0.001) compared with baseline measurements in both the cardiac rehabilitation and control groups. CONCLUSION: Cardiac rehabilitation had a positive effect on the improvement of recovery on heart rate over 1 min in patients with coronary artery disease who received CABG surgery. 相似文献

After coronary artery bypass grafting (CABG), 49 nonselected patients followed a cardiac rehabilitation program that included medical follow-up and physical training, both in outpatient groups and on an individual basis at home. The effect of the program on exercise test variables, coronary risk factors, and medication one year after surgery was compared to a nonexercised control group (n = 98). The study group showed less increase in the rate-pressure product, indicating a favorable effect on myocardial oxygen consumption (0.7 +/- 5.4 vs 2.8 +/- 5.6, p less than .05); a lower frequency of angina at exercise testing (6% vs 18%, p less than .01); a reduction in resting systolic and diastolic blood pressure (9/4mmHg, p less than .01); fewer smokers (6% vs 17%, p less than .05); and fewer patients taking long-acting nitrates (0% vs 10.2%, p less than .05). It is suggested, therefore, that an organized cardiac rehabilitation program may be advantageous after CABG. 相似文献

CT angiography is an emerging technique for the noninvasive assessment of coronary artery disease. The diagnostic performance
of different generation CT scanners has been investigated for the detection of significant stenosis (≥ 50% lumen diameter
reduction) in patients after coronary artery bypass surgery (CABG). The temporal and spatial resolution of CT scanners are
important determinants for reliable evaluation of bypass grafts and native coronary arteries. Important drawbacks of 64-slice
CT angiography remain the evaluation of severely calcified native coronary segments and distal graft anastomosis site. Future
developments in the latest CT scanners head toward the use of wider detectors and improved coverage, which may be relevant
in post-CABG patients. Despite technical advances, the role of CT angiography in the follow-up of patients after bypass surgery
has not yet been established. 相似文献

Background: We examined whether slow heart rate recovery (HRR) after exercise testing as an estimate of impaired autonomic function is related to coronary artery calcification (CAC), an emerging marker of coronary atherosclerosis.Methods: We evaluated 2088 men who participated in a health-screening program that included measures of CAC and peak or symptom-limited cardiopulmonary exercise testing. HRR was calculated as the difference between peak heart rate (HR) during exercise testing and the HR at 2?min of recovery after peak exercise. We measured CAC using multidetector computed tomography to calculate the Agatston coronary artery calcium score. Advanced CAC was defined as a mean CAC >75th percentile for each age group.Results: HRR was negatively correlated with CAC (r?=??.14, p?.01). After adjusting for conventional risk factors, participants in the lowest quartile of HRR (<38 bpm) were 1.59 times (95% CI: 1.17–2.18; p?.05) more likely to have advanced CAC than their counterparts in the highest quartile of HRR (>52 bpm). Each 1 bpm decrease in HRR was associated with 1% increase in advanced CAC after adjusting for potential confounders.Conclusions: An attenuated HRR after exercise testing is associated with advanced CAC, independent of coronary risk factors and other related hemodynamic response.
- KEY MESSAGES
Slow heart rate recovery (HRR) after maximal exercise testing, indicating decreased autonomic function, is associated with an increased risk of cardiovascular event and mortality.
Slow HRR has been linked with the occurrence of malignant ventricular arrhythmias, but it remains unclear whether slow HRR is associated with an increased risk of coronary artery calcification (CAC), an emerging marker of coronary atherosclerosis.
An attenuated HRR after exercise testing was associated with advanced CAC, independent of coronary risk factors and other potential hemodynamic confounder, supporting the hypothesis that slow HRR is related to the burden of atherosclerotic coronary artery disease.

For this study a randomized clinical trial was designed to test the effects of an early home recovery information intervention on physical functioning, psychological distress, and symptom frequency 1 month following coronary artery bypass graft surgery (CABG). Recovery outcomes were compared between two groups: those receiving an audiotape of information on expected physical sensations and their management (Cardiac Home Information Program [CHIP]) in addition to the usual care, and those receiving the usual cardiac discharge information protocol. A nonprobability sample of 180 patients (84 women and 96 men; mean age = 62 years) was equally distributed between the two study groups. When controlling for age, comorbidity, and cardiac functional status, the results showed positive effects on physical functioning in women and psychological distress, vigor and fatigue in men. Consistent with other studies, women had worse physical functioning and more symptom frequency than men. These findings indicate that the CHIP intervention is an effective method to prepare CABG patients for home recovery. 相似文献

HeartCare is an Internet-based information and support service for patients recovering at home from coronary artery bypass graft (CABG) surgery. The system is designed to meet the nursing challenges in health information to support needs of CABG patients. HeartCare (a) provides information and support, tailored to patients' individual and changing recovery needs during CABG recovery, (b) makes recovery information more accessible for timely use by patients, and (c) extends the scope of nursing services to CABG patients from hospital through home. An ongoing randomized controlled study is underway to evaluate the clinical outcomes of patients' use of the HeartCare system and to examine its acceptance as a usable resource for postCABG patients who have limited previous computer experience. 相似文献

Many hospitals have initiated early discharge programs in an effort to transition coronary artery bypass grafting patients home as quickly as possible. To meet the needs of patients who are discharged early, several home care agencies have created special cardiac programs. This article describes the common components of six successful home care cardiac programs. 相似文献

For five years, we prospectively studied 353 consecutive patients undergoing first-time coronary artery bypass graft surgery (CABG) for stable angina in the North of England. Angina was present before surgery in nearly all patients, in 20% 3 months after surgery, and in 48% after 60 months. The Nottingham Health Profile, showed a significant improvement in perceived health status (PHS) 12 and 60 months after surgery compared with preoperation. However, PHS at 60 months was worse than at 12 months in the dimensions 'pain' and 'physical mobility' in part 1, and in 'looking after the home' and 'taking holidays' in part 2. Employment rates were 36%, 34% and 21%, before, and 12 and 60 months after surgery, respectively. Working at 12 and 60 months was associated with age below retirement age, work preoperation and absence of angina, and at 12 months also with male gender and waiting time < 6 months. This study describes everyday clinical practice. The significant improvement in angina symptoms and PHS after CABG persists for at least 5 years. However, only one third of patients in this geographical area return to work, and this is not solely dependent on clinical symptoms. 相似文献

ACBGS is indicated in patients with stable angina who have left main coronary artery disease; three-vessel disease; three or four of the clinical variables set forth in the Veterans Administration Cooperative Study; obstruction in proximal third of left anterior descending coronary artery as part of two- or three-vessel disease; and two- or three-vessel disease and exercise-induced ischemic ST-segment depression greater than or equal to 1.5 mm. ACBGS may increase survival in patients with limited exercise capacity. Finally, ACBGS may be indicated to increase the quality of life in patients with disabling angina that is refractory to medical treatment. Patients with unstable angina who have an inadequate response to intensive medical therapy should have emergency ACBGS. Indications for elective ACBGS in patients with unstable angina who respond adequately to medical therapy are the same as those for stable angina. Patients with rupture of the ventricular septum, acute severe mitral regurgitation, and cardiogenic shock with vessels suitable for ACBGS should have urgent ACBGS after acute myocardial infarction. Patients with postinfarction angina after the first few days following acute myocardial infarction, especially non-Q-wave infarction, should be considered for ACBGS. Indications for elective ACBGS in postinfarction patients are the same as those in stable angina. Patients with coronary artery disease, especially those with a significant amount of ischemic myocardium, who must undergo cardiac surgery for valvular heart disease or for congenital heart disease should probably have ACBGS performed at the time of surgery. 相似文献
