Background/Aims Coronary artery bypass grafting is a complex procedure that triggers a series of clinical and functional complications. The reduction of inspiratory muscle strength that persists during the late postoperative period has been suggested as an important determinant of functional capacity after coronary artery bypass grafting. The aim of this study was to investigate whether inspiratory muscle strength, functional capacity and quality of life are determinants of exercise capacity before and after a short-term phase II cardiac rehabilitation programme in patients who have had coronary artery bypass graft surgery. Methods A prospective quasi-experimental study was undertaken with 20 patients who had recevied coronary artery bypass surgery. All patients completed a short-term, moderate-to-high intensity inspiratory muscle training programme, followed by aerobic and resistance exercise, two times a week for 12 weeks, totalling 24 sessions, under the direct supervision of a physical therapist. Results Pre-intervention, peak oxygen consumption (peak VO2) was associated with maximum inspiratory pressure (β=0.037; 95% confidence interval 0.01–0.06; P=0.002). Post-intervention, peak VO2 was associated with maximum inspiratory pressure (β=0.03; 95% confidence interval 0.007–0.053; P=0.014) and the 6-Minute Walk Test (β=0.007; 95% confidence interval, 0.001–0.013; P=0.024). Conclusions Inspiratory muscle strength influences exercise capacity before and after a short-term cardiac rehabilitation programme in patients who have had coronary artery bypass graft surgery.

Inspiratory Muscle Strength

Introduction:Cardiac anxiety(CA) is a common finding in patients in the pre- and postoperative period of coronary artery bypass graft(CABG) surgery. Ventilatory restriction generated by pain and reduced muscle strength is associated with increased CA level. Inspiratory muscle training(IMT) for generating increased muscle strength can cause a decrease in CA in the postoperative period. Objective:To evaluate the impact of IMT on inspiratory muscle strength and its relationship with cardiac anxiety in patients undergoing CABG. Methodology:This is a randomized controlled clinical trial. In the preoperative moment, all patients answered a cardiac anxiety questionnaire, composed of two domains: fear and vigilance and avoidance. In addition, their maximum inspiratory pressure(MIP) was assessed. After the surgical procedure, the patients were divided into a control group(CG) that received routine hospital care and a training group(TG) who underwent an IMT protocol until the moment of hospital discharge. Results:80 patients were evaluated,40 in each group. The IMT group showed a 17% decrease in MIP while the CG decreased 43%(p <0.01). The fear and vigilance domain had a decrease of -16±3 in the CG while in the TG the reduction was -8±3(p <0.01). The avoidance domain reduced -17±4 in the CG vs -10±4 in the TG(p <0.01). In addition, there was a strong correlation between the MIP of the TG with the domains of fear/vigilance(r -0.77) and avoidance(r -0.72). Conclusion:IMT is associated with a reduction in the loss of inspiratory muscle strength, resulting in a reduced level of cardiac anxiety in patients undergoing CABG.

Objective: The objective was to assess the effects of a nasal restriction device for inspiratory muscle training, called Feelbreathe®, added to a rehabilitation program (RP) on exercise capacity, quality of life, dyspnea and inspiratory muscle strength in patients with stable COPD. Methods: Patients were randomized into three groups, one performed a supervised RP using the Feelbreathe® device (FB group), the second group developed the same RP with oronasal breathing without FB (ONB group) and the third was the control group (CG). We evaluated inspiratory muscle strength (PImax), dyspnea (mMRC), quality of life (CAT) and exercise capacity (6MWT) before and after 8-week of RP. Results: A total of 16 patients completed the study, seven in FB group, five in ONB group and four in the CG. After the RP, the FB group showed a significant increase in PImax (93.3 ± 19.1 vs. 123.0 ± 15.8 mmHg) and in the 6MWT distance (462.9 ± 71.8 m vs. 529.1 ± 50.1 m) and a decrease in the CAT score (9.7 ± 6.5 vs. 5.9 ± 6.0) and in the mMRC dyspnea score. FB provides greater improvement in PImax, dyspnea, quality of life and 6MWT than ONB. Conclusions: The Feelbreathe® device provides greater improvements in quality of life, dyspnea, exercise capacity and inspiratory muscle strength compared to patients that did not use it.

Hba1c Levels

Background Diabetes is associated with higher mortality and worse post-operative outcomes in patients undergoing coronary artery bypass grafting and HbA1c levels have consistently been reported to be associated with adverse post-operative outcomes. However, the role of HbA1c still remains unclear with regards to the occurrence of atrial fibrillation. Method Data for the patients undergoing off-pump coronary artery bypass grafting was analysed in a retrospective fashion. Patients were divided into–those with HbA1c < 6.5% and those with HbA1c ≥ 6.5% and the incidence of atrial fibrillation observed in these two groups. We also compared patient who developed atrial fibrillation in the post-operative period and compared them with those who did not. Results Of the 5259 patients included in the study HbA1c was <6.5 in 2808 (53.4%) patients and was ≥6.5 in 2451 (46.6%) patients; 623 (11.8%) patients in our study developed atrial fibrillation. Onset of atrial fibrillation in the post-operative period was seen most commonly 235 (38.3%) on between 24 and 48 h after the operation with more than half of them 338 (54.2%) occurring within the first 48 h. On multivariate analysis, HbA1c was not a risk factor for atrial fibrillation (odd’s ratio 1.144, 95% confidence interval 0.967–1.354). Only increased age (odd’s ratio 1.08; 95% confidence interval 1.069–1.091); EuroSCORE (odd’s ratio 1.073; 95% confidence interval 1.048–1.099); history of recent MI (odd’s ratio 0.768; 95% confidence interval 0.606–0.971) and peripheral vascular disease (odd’s ratio 1.667; 95% confidence interval 1.091–2.517) were found to be independently associated with increased risk of atrial fibrillation in the post-operative period. Conclusions After adjusting for confounders HbA1c levels do not independently predict risk of atrial fibrillation after off-pump coronary artery bypass grafting.

AbstractThe relative and combined effects of sleep apnea with diabetes mellitus (DM) on cardiovascular outcomes in patients undergoing coronary artery bypass grafting (CABG) remain unknown. In this secondary analysis of data from the SABOT study, 1007 patients were reclassified into four groups based on their sleep apnea and DM statuses, yielding 295, 218, 278, and 216 patients in the sleep apnea (+) DM (+), sleep apnea (+) DM (−), sleep apnea (−) DM (+), and sleep apnea (−) DM (−) groups, respectively. After a mean follow-up period of 2.1 years, the crude incidence of major adverse cardiac and cerebrovascular event was 18% in the sleep apnea (+) DM (+), 11% in the sleep apnea (+) DM (−), 13% in the sleep apnea (−) DM (+), and 5% in the sleep apnea (−) DM (−) groups. Using sleep apnea (−) DM (−) as the reference group, a Cox regression analysis indicated that sleep apnea (+) and DM (+) independently predicted MACCEs (adjusted hazard ratio, 3.2; 95% confidence interval, 1.7–6.2; p = 0.005) and hospitalization for heart failure (adjusted hazard ratio, 12.6; 95% confidence interval, 3.0–52.3; p < 0.001). Sleep apnea and DM have independent effects on the prognosis of patients undergoing CABG.Clinical trial registration: ClinicalTrials.gov identification no. NCT02701504.
