Exercise Type in Cardiac Rehab Might Make a Difference

Introducing high-intensity interval training improved some surrogate endpoints in a small study.

I find myself very interested in the effects of high-intensity interval training (HIIT) compared with moderate-intensity continuous training (MICT). Investigators from Austria examined how these two approaches affect platelet function in 82 men who were entering outpatient cardiac rehabilitation after an acute coronary syndrome that was treated by percutaneous coronary intervention (NCT02930330). The men were on dual antiplatelet therapy and reported no previous regular exercise.

In the randomized, single-center, 12-week study, the two isocaloric exercise programs were either 2 weekly training sessions of HIIT plus 2 weekly sessions of MICT, or 4 weekly sessions of MICT. Compared with the MICT-only group, the HIIT+MICT group showed a signifi…
