Inclusion Criteria: * Major noncardiac surgery with a planned minimal postoperative hospital stay of 2 days * Age \> 59 years * Troponin\_I elevation \> 0.06 ng/ml in the first 3 post-operative days * No clinical symptoms of myocardial ischemia Exclusion Criteria: * Perioperative troponin elevation due to other factors than coronary artery disease such as proven pulmonary embolism or sepsis * Perioperative ST-elevation myocardial infarction (STEMI) * Perioperative symptomatic angina with troponin elevation * Patients with a history or ECG-signs of myocardial infarction * Patients with pre-existent heart failure, left ventricular dysfunction, significant valvular disease or left ventricle hypertrophy * Patients with significant valvular disease or left ventricle hypertrophy determined postoperatively with echocardiography. * Contra-indication for CMR such as claustrophobia or metal prosthesis * Allergic reaction to CT-contrast or gadolinium * Renal dysfunction with GFR \< 50 ml/min, as determined after the operation * Unstable hemodynamics or other conditions disabling transport to the Radiology department * Expected major discomfort or substantial increase in pain sensation by undergoing CCTA or CMR * Admission at the ICU * Poor prognosis due to other medical conditions e.g. malignancy
