Purpose: Many patients with acute coronary syndrome experience problematic or altered sexual function. This aspect of the disease is frequently ignored or overlooked by the healthcare community even though it can strongly influence health-related patient quality of life (HRQoL). Thus, the aim of this study was to compare the effects of a specific cardiac rehabilitation programme focused on aerobic and neuromuscular strength-resistance training to those of a classic rehabilitation programme, both in terms of HRQoL and erectile dysfunction in patients with acute coronary syndrome. Methods: This study reports both secondary and unregistered outcomes from a double-blinded, randomised, and controlled clinical trial. The proposed intervention was based on the completion of a 20-session (10-week) cardiac rehabilitation programme for patients with cardiovascular disease. The patient cohort had been diagnosed with acute coronary syndrome and was recruited at the Cardiology Service of a private tertiary hospital. The outcomes assessed in this study were HRQoL and erectile disfunction assessed at baseline, after the intervention, and at a 6-month follow-up. Results: A total of 30 participants were randomly allocated to each study arm. The results of the two-way mixed ANOVAs showed significant group × time interactions for all the outcome measures (EQ-5D_index, p = 0.004; EQ-5D_VAS, p = 0.017; QLMI-Q, p ≤ 0.001; and IIEF-5, p = 0.001). Conclusion: The neuromuscular strength training programme was more effective than the classic strength training programme in terms of increasing the HRQoL and improving erectile dysfunction in patients following acute coronary syndrome, with differences still remaining between these groups at the 6-month follow-up.

Background: Chronic kidney disease is closely related to a high risk of death and disability, poor physical performance and frailty. The main objective of this research was to analyse how intradialytic administration of a non-immersive virtual reality (VR) exercise programme would affect physical function and adherence to exercise in these patients. Methods: A total of 56 individuals participated in two 12-week periods in a crossover randomized controlled trial. Each patient underwent a functional capacity evaluation before and after each study period. The functional tests administered included the 4-m gait speed test, Short Physical Performance Battery (SPPB), timed up-and-go (TUG) test, one-legged stance test (OLST) for balance, sit-to-stand 10 (STS-10) and sit-to-stand 60 (STS-60) tests and 6-min walking test (6MWT). Adherence to the exercise programme was also recorded. To assess the effect of VR exercise on the functional test outcomes over time, the patients were analysed using a two-way repeated-measures analysis of variance with time and treatment as the within-participant factors. Results: By the end of the 12 weeks of exercise, compared with the control period, 33 participants showed significant change in physical function as measured through the 4-m gait speed test (0.14 m/s), SPPB (1.2 points), TUG (−1.7 s), OLST (7.1 s), STS-10 (−5.8 s), STS-60 (5 repetitions) and 6MWT (85.2 m), with adherence rates exceeding 70%. There were no changes in the biochemical data or in the medications in the period of the study. Conclusion: An intradialytic non-immersive VR exercise programme improves patient physical function.
