Background To evaluate the short- and mid-term effect of a specially tailored resistance and balance training provided in addition to usual cardiac rehabilitation (CR) care program in older patients after valve surgery/intervention. Methods Single-center (inpatient CR clinic in Lithuania) randomized controlled trial. Two hundred fifty-two patients were assessed for eligibility on the first day of admittance to CR early after (14.5 ± 5.9 days) valve surgery/intervention between January 2018 and November 2019. Participants were coded centrally in accordance with randomization 1:1 using a computerized list. Control group (CG) patients were provided with usual care phase-II-CR inpatient multidisciplinary CR program, while intervention group (IG) patients received additional resistance and balance training (3 d/wk). Patients participated in a 3-month follow-up. Main outcome measures were functional capacity (6 min walk test (6MWT, meters), cardiopulmonary exercise testing), physical performance (Short Physical Performance Battery (SPPB, score) and 5-m walk test (5MWT, meters/second)), strength (one repetition maximum test for leg press), physical frailty (SPPB, 5MWT). Results One hundred sixteen patients (76.1 ± 6.7 years, 50% male) who fulfilled the study inclusion criteria were randomized to IG (n = 60) or CG (n = 56) and participated in CR (18.6 ± 2.7 days). As a result, 6MWT (IG 247 ± 94.1 vs. 348 ± 100.1, CG 232 ± 102.8 vs. 333 ± 120.7), SPPB (IG 8.31 ± 2.21 vs. 9.51 ± 2.24, CG 7.95 ± 2.01 vs. 9.08 ± 2.35), 5MWT (IG 0.847 ± 0.31 vs. 0.965 ± 0.3, CG 0.765 ± 0.24 vs 0.879 ± 0.29) all other outcome variables and physical frailty level improved significantly (p < 0.05) in both groups with no significant difference between groups. Improvements were sustained over the 3-month follow-up for 6MWT (IG 348 ± 113 vs. CG 332 ± 147.4), SPPB (IG 10.37 ± 1.59 vs CG 9.44 ± 2.34), 5MWT (IG 1.086 ± 0. 307 vs CG 1.123 ± 0.539) and other variables. Improvement in physical frailty level was significantly more pronounced in IG (p < 0.05) after the 3-month follow-up. Conclusion Exercise-based CR improves functional and exercise capacity, physical performance, and muscular strength, and reduces physical frailty levels in patients after valve surgery/intervention in the short and medium terms. SPPB score and 5MWT were useful for physical frailty assessment, screening and evaluation of outcomes in a CR setting. Additional benefit from the resistance and balance training could not be confirmed. Trial registration NCT04234087, retrospectively registered 21 January 2020.

Objectives To evaluate 20 days and 3 months follow-up effectiveness of cardiac rehabilitation (CR) enhanced by resistance/balance training and telephone-support program compared to usual CR care in improving quality of life, clinical course and physical activity behavior. Design Single-centre randomized controlled trial. Setting Inpatient CR clinic Subjects 116 (76.1 ± 6.7 years, 50% male) patients 14.5 ± 5.9 days after valve surgery/intervention were randomized to intervention group (IG, n = 60) or control group (CG, n = 56). Intervention Additional resistance/balance training (3 days/week) during phase-II CR and telephone-support program during 3-month follow-up. CG patients were provided with usual CR care. Main measures Short Form 36 Health Survey scales, European Quality of Life 5 Dimensions 3 Level Version QoL index, visual analog scale, clinical course, and physical activity behavior assessed with standardized questionnaires. Results IG reported statistically significant higher mental component score (48.5 ± 6.91 vs. 40.3 ± 11.21 at the baseline, 50.8 ± 9.76 vs. 42.6 ± 9.82 after 20 days, 49.4 ± 8.45 vs. 40.5 ± 8.9 after 12 weeks follow up), general health (48.6 ± 3.17 vs. 45.0 ± 2.95 at the baseline, 53.6 ± 3.02 vs. 43.8 ± 2.55 after 20 days, 53.2 ± 3.11 vs. 44.2 ± 3.07 after 12 weeks) and role limitations due to emotional problems (48.5 ± 15.2 vs. 27.7 ± 11.5 at the baseline, 72.7 ± 12.6 vs. 30.5 ± 11.2 after 20 days, 66.6 ± 14.2 vs. 36.1 ± 11.2 after 12 weeks) in all three assessments ( p < 0.05). CG patients had more documented hospital admissions (4 (8%) vs 10 (25%), p = 0.027), atrial fibrillation paroxysms (3 (6.0%) vs. 10 (35.0%), p = 0.011) and blood pressure swings (13 (26%) vs. 20 (50%), p = 0.019). IG patients chose more different physical activities (1.7 ± 0.7 vs. 1.25 ± 0.63, p = 0.002), spent more time being physical active every day (195.6 ± 78.6 vs. 157.29 ± 78.8, p = 0.002) Conclusions The addition of resistance/balance exercises and telephone-support program 12 weeks after to the CR could linked to higher physical activity levels and fewer clinical complications but did not lead to a significant improvement in quality of life.

Background and Objectives: Nearly 23% of elderly patients hospitalized due to acute coronary syndrome have reduced muscle strength. It is assumed that these patients would better benefit from a complex training—a combination of endurance, strength, balance, coordination, and flexibility—in order to reduce the loss of muscle strength and mass and improve functional capacity. The aim of this study was to assess the effectiveness and safety of two different complementary resistance and balance training programs during short-term cardiac rehabilitation (CR) in elderly patients after a percutaneous or surgical intervention due to acute coronary syndrome. Materials and Methods: This randomized controlled trial was conducted from January 2020 to February 2021 in one Lithuanian rehabilitation hospital. A total of 63 participants who met the inclusion criteria were randomly assigned to three groups (at the ratio of 1:1:1): control (CG, n = 19), intervention 1 (IG-1, n = 26), and intervention 2 (IG-2, n = 18). All the patients attended a usual inpatient CR program of a mean duration of 18.7 ± 1.7 days, while the patients assigned to the intervention groups (IG-1 and IG-2) additionally received different resistance and balance training programs three days a week. Functional capacity, with 6-minute walk test (6MWT) and cardiopulmonary exercise testing (CPET), as well as physical performance, with the short physical performance battery (SPPB) test and one repetition maximum test (1RM) for leg press, were assessed at baseline and after CR. Results: The mean age of the participants was 72.9 ± 5.5 years; 73% were men. All parameters of functional capacity and physical performance improved significantly after CR (p < 0.05), except for peak VO2 that improved only in the IG-1. Comparison of CR effectiveness among the groups revealed no significant differences. Conclusions: All three rehabilitation programs were safe and well tolerated by elderly patients aged ≥65 years as well as improved functional capacity (6-minute walk distance and peak workload) and physical performance (SPPB and 1RM). Complementary resistance and balance training with traditional physical therapy means and exercises with mechanical devices did not show greater benefits for the results of physical performance compared with the usual CR program.

Background and Objectives: The world’s population is rapidly aging, and it is estimated that, by 2050, every sixth person on earth will be older than 65 years. Around 30% of older adults entering cardiac rehabilitation (CR) meet the criteria of frailty. Frailty identification has not been included in the routine evaluation of CR patients yet, and there is a lack of evidence on what training regimen for improving physical performance in frail people is optimal. Therefore, the aim of our study was to determine the prevalence of frailty and to evaluate the effect of two different complementary training programs on the gait speed of older vulnerable and frail patients with acute coronary syndrome and mid-range-to-preserved left ventricular ejection fraction (≥40%) during short-term CR. Materials and Methods: This randomized controlled trial was conducted from January 2020 to September 2021. CR participants (n = 97) with a mean age of 73.1 ± 5.3 years were randomly allocated into three groups: control (CG, n = 32), intervention-1 (IG-1, n = 32) and intervention-2 (IG-2, n = 33). The patients of all three groups attended a usual inpatient CR program, and two intervention groups additionally received different resistance and balance training programs 3 days a week: the IG-1 underwent complementary training with traditional means of physical therapy, while the IG-2 underwent complementary training with mechanical devices. The mean CR duration was 18.9 ± 1.7 days. Frailty was assessed with the Edmonton Frail Scale, and the 5 m walk test was used to evaluate gait speed. Results: Frailty was determined in 37.1% of participants, and 42.3% met the criteria of being vulnerable. After CR, the gait speed of frail and vulnerable patients significantly improved in all three groups (p < 0.05). In the IG-2, slow gait speed was reversed to normal in the overwhelming majority of patients (p < 0.05), while the CG had the greatest proportion of patients who remained to be slow after CR (p < 0.05). Conclusions: A considerable part of patients entering CR are frail or vulnerable; therefore, it is of crucial importance to assess frailty status in all older people. All three CR programs improved gait speed in frail and vulnerable older patients with ischemic heart disease. Complementary resistance and balance training with mechanical devices more effectively reversed slow gait speed to normal during short-term CR.

Due to frailty, cardiac rehabilitation in older patients after open-heart surgery must be carefully tailored, thus calling for informative and convenient tools to assess the effectiveness of exercise training programs. The study investigates whether heart rate (HR) response to daily physical stressors can provide useful information when parameters are estimated using a wearable device. The study included 100 patients after open-heart surgery with frailty who were assigned to intervention and control groups. Both groups attended inpatient cardiac rehabilitation however only the patients of the intervention group performed exercises at home according to the tailored exercise training program. While performing maximal veloergometry test and submaximal tests, i.e., walking, stair-climbing, and stand up and go, HR response parameters were derived from a wearable-based electrocardiogram. All submaximal tests showed moderate to high correlation (r = 0.59-0.72) with veloergometry for HR recovery and HR reserve parameters. While the effect of inpatient rehabilitation was only reflected by HR response to veloergometry, parameter trends over the entire exercise training program were also well followed during stair-climbing and walking. Based on study findings, HR response to walking should be considered for assessing the effectiveness of home-based exercise training programs in patients with frailty.
