Objectives: To get insight in the mechanism of exercise‐induced ST‐segment elevation (STE) in patients with Q/QS waves at the electrocardiogram (ECG). Methods: We performed exercise stress test in 13 patients with anterior acute myocardial infarction treated by successful primary percutaneous coronary intervention (PCI). Results: Compared to rest, an additional STE > 1 mm in one or more precordial ECG leads during exercise occurred in nine patients (69%), in the absence of symptoms. Conclusions: In acute myocardial infarction (MI) patients, treated by primary PCI and showing optimal coronary blood flow restoration at angiography, STE can still be induced by exercise in Q/QS wave ECG leads. This finding lends further support to the theory that exercise‐induced STE in this clinical context is unlikely to represent by itself transient myocardial ischemia or viability.
