The Norwegian Trial of Physical Exercise After Myocardial Infarction

Supervised home-based and community-based physical exercise with a dose required to increase cardiorespiratory fitness, i.e. intensity, duration and frequency that accumulates to at least 115 minutes a week of exercise, divided into at least 20 minutes a week of high/vigorous intensity physical activity (active minutes at about 85% of peak heart rate or Rated Perceived Exertion \[RPE\] of about 16 on Borg scale) and 95 minutes a week at moderate-intensity physical activity (active minutes at about 70% of peak heart rate or RPE of about 13 on Borg Scale), or continuous heart rate measurements amounting to at least 100 Personal Activity Intelligence (PAI) equivalents per week.

Standard care, i.e. advice at study start to follow international guidelines of moderate to vigorous physical activity intensity without further guidance and follow-up by study personnel.

Follow-up through mandatory national heath registries for primary endpoint, without any contact by study personnel
