Low ALT blood levels are associated with lower baseline fitness amongst participants of a cardiac rehabilitation program

Lower ALT values, measured prior to the initiation of cardiac rehabilitation programs may indicate frailty of patients and be indicative for poor rehabilitation outcomes. Further, prospective studies should assess the potential correlation between ALT values and rehabilitation efficiency. We aimed to assess the potential correlation between the baseline ALT values and the baseline exercise capacity, as expressed in METs (Metabolic equivalent of tasks). 3806 patients were included in our study.
