Complete revascularisation vs culprit‐only revascularisation

Long‐term all‐cause mortality (≥ 1 year after the intervention) · people with STEMI and MVD.

It is very uncertain whether complete revascularisation changes long‐term all‐cause mortality (≥ 1 year after the intervention) compared with culprit‐only revascularisation (very low certainty).
