Abstract Introduction A high proportion of elderly patients with Chronic Heart Failure (CHF) experience dyspnea and fatigue during the activities of daily living (ADLs). Purpose We aimed to determine 1) the VO2 peak of some basic ADLs comparing it to VO2 peak at CardioPulmonary Exercise Test (CPET) and 2) the effects of 3-week inpatient cardiac rehabilitation program on ADLs' performance. Methods At entry and at the end of a 20-day cardiac rehabilitation program patients performed an ADL-test consisting of five task-related ADL activities and two time-related ADL activities while wearing a metabolimeter mobile device (K5, Cosmed). Task-related activities were: 1) to put on and take off socks, shoes and jacket (ADL 1); 2) to fold eight towels (ADL 2); 3) to put 6 bottles on a shelve (ADL 3); 4) to make a bed (ADL 4); 5) to go up and down 1-floor stairs (ADL 5). Time-related ADL activities were: 1) to sweep the floor for 4 minutes (ADL 6) and 2) to walk for six minute (6MWT). Metabolic load, oxygen uptake, ventilation, heart rate and symptom of dyspnea were computed for each ADL. During the program, patients performed a CPET. Results Fifty-six CHF patients [89% men; age 72±6 years; Ejection Fraction (EF) 38±12%; 66% with EF<40%] were enrolled. At entry, the least demanding ADL [expressed as proportion of peak oxygen uptake (VO2 peak) reached at CPET] was ADL 3 with 53,14±18.53%, while the most challenging was the 6MWT with 116.81±34.48%. Forty-two (75%) patients reached the VO2peak of CPET during 6MWT. After rehabilitation, there was a significant decrease in the time required to perform the task-related activities (ADL 1–5) [from 382.25±114.90 to 354.48±116.92 seconds, p=0.0175] and a significant increase in the distance covered during 6MWT [from 421.35±81.64 to 448.84±89.69 meters, p=0.000]. Moreover, following rehabilitation a significant decrease of heart rate in ADL1, ADL 3 and ADL 5 and a significant decrease of dyspnea in ADL 5, ADL 6 and 6MWT was recorded. Conclusion A comprehensive cardiac rehabilitation program can improve ADL performance due to the change of some physiological variables during effort. Further studies about the role of dedicated rehabilitation program (i.e. occupational rehab) are necessary.

Abstract Background Cardiac rehabilitation has been shown to reduce cardiac mortality, improve quality of life, and reduce hospitalizations. Cardiac rehabilitation programs are usually performed over a 12-week period. Studies have shown that similar benefits could be achieved with shorter programs. Abnormal heart rate recovery after exercise has been associated with an increased risk of cardiovascular events and mortality. The main aim of this study was to compare the effect of a 6-week phase 2 cardiac rehabilitation program on heart rate recovery to a 12-week one in patients who had recovered from an anterior wall ST segment elevation myocardial infarction. Results This prospective study included 60 patients enrolled in cardiac rehabilitation programs randomized into two equal groups: a 6-week and a 12-week program. Baseline patient demographics, lipid profile, and left ventricular ejection fraction (LVEF) were assessed. METs achieved, total exercise time, resting heart rate, peak heart rate, and heart rate recovery at 1 min were examined. These were re-assessed at the end of each program. Results showed no difference between both groups at the end of each program regarding lipid profile and LVEF. Patients enrolled in the 12-week cardiac rehabilitation program were able to achieve more METs, had a longer exercise time, a higher peak heart rate, and had a lower resting heart rate at the end of the program. Heart rate recovery was slightly higher in patients enrolled in the 6-week program 26.5 ± 6.78 versus 23.17 ± 6.12 bpm (p = 0.051). On comparing the magnitude of change between both programs, those in the 12-week program had more increase in HDL-C levels, METs achieved, and exercise time. Additionally, they had more reduction of resting heart rate. Heart rate recovery was more increased for those in the 6-week program. Conclusion Although heart rate recovery increases after completion of each of a 6-week and 12-week cardiac rehabilitation program compared to their baseline, there is no difference on comparing heart rate recovery between both programs at their end. Patients enrolled in a standard 12-week cardiac rehabilitation program achieve more METs, have a longer exercise time, a higher peak HR, and a lower resting HR at the end of the program compared to those in the 6-week program.

Introduction  Due to the increase in global prevalence of degenerative valve disease, aortic stenosis (AS) has played a preponderant role in the cardiovascular scenario, especially in patients undergoing transcatheter aortic valve replacement (TAVR). An alternative management for this patients are the cardiac rehabilitation programs (CRP); however, their effect has not been completely understood, both in exercise capacity and quality of life, but neither in the improvement of cardiopulmonary performance and other cardiovascular outcomes.  Purpose: To evaluate the effect of the CRP on exercise tolerance and cardiopulmonary performance in patients with AS undergoing TAVR.  Methods: A cohort study was conducted including 26 patients with AS undergoing TAVR and divided into an intervention group who performed a 4-week supervised training program in the Cardiac Rehabilitation Service and a control group to whom instructions and recommendations to performed unsupervised exercise at home were given. Demographic and clinical data (VO2Max, METS12, oxygen pulse, heart rate, double product, left ventricular ejection fraction, body mass index) were collected at baseline and after a 4-week follow-up. Results: 15 patients were included in the intervention group and 11 patients in the control group. There were no baseline significant differences between groups. After the intervention, significant differences were observed in the METS 12 final gain variable between the control and intervention group (4.55 vs 3.1 p = 0.01). Intergroup analysis showed significant differences (percentage changes) in the intervention group with an increase of METS12 (67.4%, p = 0.001), oxygen pulse (18.21%, p = 0.01), final METS (39.47% p = 0.001) and a decrease in VO2 recovery time (-12.5%, p = 0.05), in the ergometric performance index by heart rate (-38.17%, p = 0.001) and by double product (-38.1%, p = 0.001). Conclusions  A 4-week cardiac rehabilitation program is effective to improve exercise tolerance and cardiopulmonary response in patients with AS undergoing TAVR; improvement was statistically significant in METS12, oxygen pulse, VO2 recovery time, METS-load and ergometric performance index for heart rate and double product. METS12 final gain was statistically significant in intervention group in comparison with the control group. Abstract Figure. Control vs Intervention Group (METS12)
