As a growing number of elderly patients with known coronary artery disease (CAD) or with risk factors for CAD are undergoing non- cardiac surgery, cardiovascular clinical problem in the future. The number says approximately 100 million adults undergo non-cardiac surgery worldwide have or are at risk of coronary artery disease (CAD) 2 perioperative cardiovascular complication, . In perioperative cardiac complications varies population and type of surgery 3-5 . of primary symptoms in the perioperative period leads to the difficulty to detect PMI may be the major reason for these high mortality rates 10 PMI have typical chest pain and consequently 53% of the PMI will not be diagnosed if the physician relies only on symptoms or clinical signs 11 . specific troponins are vital[Importance of the study]. Though, the appropriate cut- off levels for detecting myocardial damage using troponins in a surgical setting are debated. Elevated troponin with or without clinical or ECG signs of ischaemia are known to be associated with poor outcome both in patients with acute coronary syndrome 12 non-cardiac surgery 13, 14 provide information and recommendations perioperative evaluation and management including perioperative cardiac risk cardiac evaluation, recommendations perioperative cardiac intervention prior coronary intervention, perioperative
