Induction of myocardial ischemia reperfusion injury. (A) Interventional setup with an angiography x-ray system for catheter-based balloon occlusion of a coronary artery. (B) Coronary angiogram showing the left coronary artery (highlighted in red) with the LAD occluded downstream of the origin of the first ramus diagonalis (RD). The estimated position of the balloon for an LCX occlusion is indicated by “*”. (C) Typical progressive ECG changes during LAD occlusion: In the initial pre-ischemic state, a sinus rhythm without signs of ischemia. Within the first 5–10 min of ischemia, ST-segment elevations > 0.1 mV and reciprocal depressions emerge, becoming progressively more pronounced over time. Ventricular ectopic beats frequently appear after approximately 30 min of ischemia. Immediately following reperfusion, pronounced T-wave changes are evident.
