Abstract
An important component of secondary prevention of CVD (including HF) is comprehensive cardiac rehab, including exercise. Novel, individualised approaches are needed to increase uptake and adherence to exercise programmes. One area offering potential is HIIT. HIIT has been shown to be both safe and effective for improving cardiovascular fitness in both coronary artery disease and HF patients. The objective of this study was to provide a current and up-to-date evaluation of the physiological and psychological outcomes of HIIT in patients with HF, compared to MCT and UC. A secondary objective was to perform sub-group analyses comparing short and long HIIT protocols. A systematic review and meta-analysis of randomised controlled trials was undertaken. Medline, Embase, Scopus, CINAHL and SportDISCUS were searched up to July 2022. Trials were included if they carried out a HIIT intervention (defined at intensity ≥ 80% peak HR or ≥ 80% VO2peak) in HF patients (HFpEF or HFrEF) for at least 6 weeks. Comparator group was UC or MCT. HIIT was shown to be superior to MCT and UC for improving VO2peak (HIIT mean improvement 3.1mL.kg-1min-1). HITT was superior to MCT and UC for improving LVEF (HIIT mean improvement 5.7%). HIIT was superior to MCT and UC for improving HRQoL, using the MLHFQ (HIIT mean point change of -12.8). Subgroup analysis showed no difference between long and short HIIT. The study therefore concluded that HIIT improves VO2peak, LVEF and HRQoL in patients with HF, with the improvements seen in VO2peak and LVEF being superior in HIIT compared to MCT and UC.
