Objective Try to carry out the intervention experiment of the strength exercise of the elderly in the community, aiming to provide theoretical and data basis for the daily strength exercises of the elderly in China. Methods  Recruiting 18 elderly female volunteers in Xicheng District, Beijing, required independent living ability and were willing to participate in the experiment. They were randomly divided into intervention group (N=9, 62.0±6.0 years) and control group (N=9, 63.0 ± 4.8 years). On Tuesday afternoon and Thursday morning, under the leadership of a professional coach, follow the planned "Resistance Exercise Plan" to carry out resistance training. Each practice time is about 90min for 9 weeks. The exercise intensity control is divided into two phases: the first phase lasts for one week, mainly the learning and adaptation phase of the action, and the heart rate control in the 30%~40%HRR or RPE 10 subscale is 4 (a little easy); The stage lasts for 8 weeks of the medium-intensity practice phase, the heart rate control in the 40%~60%HRR or RPE 10 subscale is 5~6 (moderate, slightly strenuous). Results Intervention group before and after experiment, the grip strength (25.0±5.0 VS 26.8±3.9 kg, P<0.05) and the 30s arm curl test (23.1±5.2 VS 25.4±4.0 reptitions, P<0.05) increased. Five sit-up tests (6.99±2.01 VS 6.51±2.00 s, P<0.05) and the 8-foot standing walk (5.13±1.03 VS 5.07±1.01 s, P<0.05) were all shortened. The bone density T value (-1.3±0.4 VS -1.0±0.4, P<0.05) increased. After intervention, the intervention group compared with the control group, grip strength (26.8 ± 3.9 VS 22.1 ± 4.5 kg, P <0.05), 30s arm curl test(25.4 ± 4.0 VS 22.1 ± 3.0 reptitions, P <0.05) increased. Five sit-up tests (6.51 ± 2.00 VS 6.94 ± 1.05 s, P < 0.05) and 8 feet of standing walk (5.07 ± 1.01 VS 5.27 ± 0.97 s, P < 0.05) were all shortened. Bone density T value (-1.0 ± 0.4 VS - 1.4 ± 0.4, P < 0.05) increased. There was no significant change in the 30-second chair stand test. Conclusions Through 9 weeks of progressive resistance exercise, the experiment made the upper limb explosive force, upper limb muscle endurance, lower limb explosive power, flexibility and dynamic balance enhanced, and bone density increased. The enhancement of lower limb endurance is not obvious, which may be the reason for short experimental time and small exercise intensity of lower limbs.

Background : Although type B aortic dissection (AD) has been treated with beta-blocker to lower the arterial blood pressure (BP), there has been little evidences about reduction in heart rate (HR). We assessed whether tight HR control improved the outcome of medical treatment in patients with AD. Methods and Results : From 1997 to 2005, consecutive 223 patients with AD medically treated and controlled to lower BP under 120 mmHg were enrolled. Based on the average HR at 3, 5, and 7 days after the onset, patients were divided to tight HR (<60 bpm) control group (39 patients; mean HR of 56 .8bpm) and conventional HR (equal or more than 60 bpm) control group (184 patients; mean HR of 71.6 bpm). We compared the frequency of aortic events including aortic rupture, recurrent dissection, and aortic expansion of more than 5mm, and surgical requirement between two groups. During a median follow-up of 33.3 months, aortic rupture, recurrent dissection, pathological aortic expansion, and aortic surgery occurred in 3, 14, 43, and 30 patients respectively. Reductions in aortic events and surgical requirement were observed in tight HR control group (10.3% and 2.6%) compared to conventional HR control group (28.3% and 15.8%) (Odds ratio: 0.29 and 0.14. C.I.:0.10 to 0.90 and 0.02 to 1.07, p<0.01.). Kaplan-Meier curves of aortic event and surgical requirement free rates were shown in figure 1 and 2 . Conclusions : The present study demonstrated that tight heart rate control improved the outcome of medical treatment in patients with AD.

Abstract Background Few studies examined interventions in frail elderly in China, while the awareness of applying interventions to prevent frailty in pre-frail elderly is still lacking. This study aimed to explore the effects of lower limb resistance exercise in pre-frail elderly in China. Methods This was a randomized controlled trial of patients with pre-frailty. The control group received routine care, while the exercise group received a 12-week lower limb resistance exercise based on routine care. The muscle strength in the lower limbs, physical fitness, and energy metabolism of the patients was evaluated at admission and after 12 weeks of intervention. Results A total of 60 pre-frail elderly were included in this study. The patients were divided into the exercise group (n = 30) and control group (n = 30) by random grouping. There were 17 men and 13 women aged 65.3 ± 13.4 in the exercise group, and 15 men and 15 women aged 67.6 ± 11.9 years in the control groups. The Barthel index was 80.3 ± 10.6 and 85.1 ± 11.6, respectively. The characteristics of the two groups were not significantly different before intervention (all p > 0.05). The results of repeated measurement ANOVA showed that there was statistically significant in crossover effect of group * time (all p < 0.05), that is, the differences of quadriceps femoris muscle strength, 6-min walking test, 30-s sit-to-stand test, 8-ft “up & go” test, daily activity energy expenditure and metabolic equivalent between the intervention group and the control group changed with time, and the variation ranges were different. The main effects of time were statistically significant (all p < 0.05), namely, femoris muscle strength, 6-min walking test, 30-s sit-to-stand test, 8-ft “up & go” test, daily activity energy expenditure and metabolic equivalent of the intervention group and the control group were significantly different before and after intervention. The main effects of groups were statistically significant (p < 0.05), namely, femoris muscle strength, 6-min walking test, 30-s sit-to-stand test, daily activity energy expenditure and metabolic equivalent before and after intervention were significantly different between the intervention group and the control group, while there was no significant differences in 8-ft “up & go” test between groups. Conclusion Lower limb resistance exercise used for the frailty intervention could improve muscle strength, physical fitness, and metabolism in pre-frail elderly.

Abstract Funding Acknowledgements Type of funding sources: None. 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)

Abstract Background Previous studies highlighted the importance of adequate heart rate control in heart failure patients, and suggested under-treatment with beta-blockers especially in women. However, data on women achieving effective heart rate control during beta-blocker therapy optimization are lacking. Methods The wearable cardioverter defibrillator (WCD) allows continuous monitoring of heart rate (HR) trends during WCD use. In the current study, we assessed resting HR trends (nighttime: midnight-7am) in women, both at the beginning of WCD use and at the end of WCD use to assess the adequacy of beta-blockade following a typical 3 months of therapy optimization with beta-blockers. An adequate heart rate control was defined as having a nighttime HR <70 bpm at the end of the 3 months. Results There were a total of 21,453 women with at least 30 days of WCD use (>140 hours WCD use on the first and last week). The mean age was 67 years (IQR 58–75). The mean nighttime heart rate was 72 bpm (IQR 65–81) at the beginning of WCD use, that decreased to 68 bpm (IQR 61–76) at the end of WCD use with therapy optimization. Women had an insufficient heart rate control with resting heart rate ≥70 bpm in 59% at the beginning of WCD use that decreased to 44% at the end of WCD use, but still remained surprisingly high. Interestingly, there were 21% of the women starting with HR ≥70 bpm at the beginning of use (BOU) who achieved adequate heart rate control by the end of use (EOU). Interestingly, 6% of women with adequate heart rate control at the start of therapy optimization ended up having higher heart rates >70 bpm at the end of the therapy optimization time period (Figure). Figure 1 Conclusions A significant proportion of women with heart failure and low ejection fraction do not reach an adequate heart rate control during the time of beta blocker initiation/titration. The wearble cardioverter defibrillator is a monitoring device that has been demonstrated in this study to appropriately identify patients with inadequate heart rate control at the end of the therapy optimization period. The WCD could be utilized to improve management of beta-blocker therapy in women and improve the achievement of adequate heart rate control in women.
