Multivessel coronary artery disease (MVCAD) is common in patients with ST-elevation myocardial infarction (STEMI), thereby negatively affecting mortality and outcome. Currently there is increasing evidence that complete revascularisation should be considered in haemodynamically stable patients. There are few larger randomised controlled trials available showing a lower risk of major adverse cardiac events after complete revascularisation, mainly driven by a reduction of repeat revascularisation. However, these trials are not adequately powered to show a mortality benefit or reduced risk of myocardial infarction. As there are several possible strategies, the presence of MVCAD often poses a therapeutic dilemma for interventional cardiologists and there is still ongoing debate on when and how to perform complete revascularisation. Pending further trials that may clarify which strategy is best, an individualised approach should be adopted.
