    Abstract:
    Percutaneous coronary intervention is the first-line treatment for ST-elevation myocardial infarction. In the setting of multivessel disease, concomitant reperfusion of all obstructed vessels is controversial, notably when the culprit vessel cannot be easily identified. We describe two cases with acute inferior-posterior myocardial infarction (ST-segment elevation in the inferior leads and ST-segment depression in the precordial leads). In the first case, angiography revealed severe three-vessel disease and the culprit vessel could not be identified. Following standard pharmacological therapy, the clinical picture and the ECG pattern improved, so that coronary revascularization was postponed. In the second case, angiography showed two-vessel disease with total occlusion of the right coronary and left circumflex arteries, which was treated with coronary angioplasty and drug-eluting stent implantation on the right coronary artery. In patients who undergo coronary angioplasty immediately, careful reading of the ECG can be a reliable tool for the identification of the culprit vessel in ST-elevation myocardial infarction associated with multivessel disease, allowing to choose the appropriate reperfusion strategy.
