Patients with chest discomfort or other ischaemic symptoms, who develop new ST-segment elevations in two contiguous leads or new bundle branch blocks ST-elevation is defined as ST segment elevation myocardial infarction in the guideline titled 'The fourth universal definition of myocardial infarction' published by the European Society of Cardiology in 2018. Elevation in the segment of the ECG can be observed in other non-cardiac pathologies apart from acute coronary syndrome. The displacement of the mediastinal structures in thorax surgeries is a rare cause of pseudoischemic ECG changes. Our case is a 63 years old male patient who has no cardiovascular risk factors except smoking. In the postoperative period of our patient, whom right lung resection due to lung malignancy is performed, ECG demonstrates diffuse ST segment elevation in precordial leads. In this case report, it is aimed to present a patient of pneumonectomy which may cause ST segment elevation in ECG, as a non-cardiac pathology, whose coronary angiography revealed normal coronary arteries.
