Key result
Low-volume high-intensity interval training attenuated dysfunctional ventricular remodeling by preventing wall thinning and improving diastolic function, including a 21.7% reduction in ST2 levels, in post-myocardial infarction patients.
Why the study?
Aerobic HIIT benefits post-MI ventricular remodeling, but the optimal training volume is not well known.
Does low-volume or high-volume aerobic HIIT improve echocardiographic and biochemical indicators of LV remodeling in post-MI patients with preserved ventricular function?

Low-volume HIIT is a time-efficient strategy that improves left ventricular function and attenuates dysfunctional remodeling in post-MI patients with preserved ventricular function.

Low-volume HIIT attenuates post-MI LV remodeling without wall thinning; supports time-efficient rehab protocols in preserved-EF patients.
Aispuru-Lanche et al. (2023) conducted an RCT in Myocardial infarction with preserved ventricular function (n=80). Aerobic high-intensity interval training (HIIT) vs. Attentional control was evaluated on Left ventricle end-diastolic diameter (LVEDD) (p=0.85). Low-volume high-intensity interval training attenuated dysfunctional ventricular remodeling by preventing wall thinning and improving diastolic function, including a 21.7% reduction in ST2 levels, in post-myocardial infarction patients.
