Evaluating The Impact of High-Intensity Interval Training on Fitness, Patient Satisfaction, and Exercise Adherence in Heart Failure Rehabilitation

Abstract

Background: High-Intensity Interval Training (HIIT) exercise is reported to be an appropriate training mode on health and cardiorespiratory fitness. In other cases, there is no data on the role of HIIT on cardiac rehabilitation outcome with regard to heart failure. This paper concludes by founding its rationale in establishing the applicability of HIIT on physical fitness and satisfaction within the rehabilitation regimens and the obstacles of obtaining HIIT in the long run outlook in the situation with heart failure patients.

Objective: The current paper targets the identification of the effects of HIIT on patient reported outcomes, fitness and exercise barriers in heart failure patients. This specific study aims to determine the utility of HIIT in illuminating cardiovascular fitness, the perception that the subjects concerned had about the rehabilitation program, and also the problems which the subjects face as far as the adoption of HIIT is concerned when they are over with their formal rehabilitation program.

Methods: A survey was developed and given in electronic form to a group of one hundred sixty-seven respondents which included heart failure patients who have undergone cardiac rehabilitation on the basis of HIIT. The questionnaire that included several sets of questions with different parameters was posted including demography, fitness status and fitness appraisals before and after the HIIT program as well as the level of supplier to practicing the HIIT program and the challenges during the heteronance when looking at the HIIT program. The survey was carried out between the 1st March 2024- 30 th march 2024. It was performed by the quantitative analysis of the quantitative data by the descriptive statistics, and the theme analysis of the qualitative data.

Results: There were strong indications of the resultant enrichments of fitness such as enhanced ability and spirit after a couple of weeks of HIIT. The results showed that the percentage of the cohort reporting having high satisfaction with the program was almost 65 percent with the responses being that they felt fitter and healthier more significantly and their hearts were healthier. Nevertheless, numerous impediments to HIIT continuation post-rehabilitation (including time, physical capacity, and resource shortage), were the reasons mentioned. Nevertheless, the majority of respondents declared their readiness to do HIIT assuming they received the relevant support and resources.

Conclusion: This shows, therefore, the benefits of HIIT for rehabilitation for those who had experienced heart failure, where significant increases in levels of fitness and high patient satisfaction were noted. HIIT may be problematic for some groups due to physical barriers or a lack of access to the required expertise or equipment so quality of life improvements will need to be sustained to underpin a longer-term exercise strategy. Future considerations should focus on overcoming these barriers and evaluating the cost-effectiveness of HIIT for cardiac rehabilitation.
