SMI is recognized as a common manifestation after percutaneous coronary interventions (PCIs) (1-2). PCIs can induce coronary artery spasm that causes ischemia (2). As catheterization laboratory procedures have become progressively more invasive with multivessel interventions, prolonged balloon inflation times, use of multiple guiding catheters and the advent of coronary stenting, the propensity for PCI-induced spasm has increased. We report a patient who had a brief period of intense epicardial ischemia after percutaneous transluminal coronary angioplasty (PTCA), possibly due to coronary artery spasm. Although this clinical picture is not unusual, the authors find the ECG changes during SMI very exceptional.eninfo:eu-repo/semantics/openAccessSilent İschemiaCoronary SpasmSessiz İskemiKoroner SpazmCase Report3521271302-s2.0-17244369051Q346251
