Predicting the occurrence of minor adverse events in cardiac rehabilitation using physical variables.

The safety of exercise practice by individuals with cardiovascular disease is due to a good clinical evaluation to identify patients with a higher risk of adverse events, thus the study of simple variables capable of predicting the rate of events during exercise is relevant and may provide better screening tools to be applied in the clinical practice. The study aimed to evaluate if clinical and physical parameters can predict the rate of adverse events during exercise-based cardiac rehabilitation. This was a cohort study that followed 73 patients during 24 sessions of exercise. Were registered 217 simple adverse events, at a rate of 2.5 events per hour of exercise. We found that higher adiposity, worse pulmonary function, lower functional capacity, and reduced heart rate variability were significant and acceptable predictors of adverse events during exercise, according to the ROC curve analysis. We state that these simple physical parameters may be useful for cardiac risk stratification in cardiac rehabilitation programs with low resources, contributing to its safety.

Perceptions and preferences of patients with cardiac conditions to the inclusion of virtual reality-based therapy with conventional cardiovascular rehabilitation: A qualitative study.

BACKGROUND: Virtual reality-based therapy (VRBT) has been recently used in rehabilitation programs, as it can improve patient's adherence to treatment. However, patients' acceptance of VRBT has been scarcely investigated. OBJECTIVE: To qualitatively analyze the perceptions and preferences of patients about the inclusion of VRBT to a conventional cardiovascular rehabilitation program (CRP). METHODS: Fifteen patients from a randomized clinical trial participated in focus groups for qualitative assessment. RESULTS: Patients demonstrated good acceptance and satisfaction of VRBT. Physical and psychosocial benefits were highlighted, and patients reported the perception of higher exercise intensity in VRBT then when doing conventional training. In addition, the frequency of VRBT (once a week), associated with conventional treatment was reported as satisfactory. Cognitive aspects that influenced participation to the new approach were also raised by study participants. CONCLUSION: Patients with cardiac conditions demonstrated satisfaction with the inclusion of VRBT in a conventional CRP, demonstrating that VRBT has the potential to be a new approach for this patient population, allowing training diversification. Benefits perceived by patients include physical, mental, and social aspects. TRIAL REGISTERED: NCT04336306 (https://clinicaltrials.gov/ct2/show/NCT04336306).
