All of the following statements about Universal Definition of Myocardial Infarction are true, Except:

A
Sudden, unexpected Cardiac death with symptoms of Ischemia.
B
Elevation of cardiac biomarkers with new regional wall motion abnormality
C
Three times increase in Troponin levels after Percutaneous Coronary Intervention (PCI)
D
Three times increase in Troponin levels after Coronary Aery Bypass Grafting (CABG)
High-Yield Explanation
Answer is D (Three times increase in Troponin levels after Coronary Aery Bypass Grafting (CABG) Myocardial Infarction associated with CABG is defined by an increase in cardiac biomarkers to more than 5 times normal (> 5 times above the 99th percentile). Universal Defination of Myocardial infarction Myocardial infarction related to ischemia due to primary coronary event (plaque rupture) or imbalace between oxygen demand and supply (coronary spasm, hypotension etc) . Myocardial Infarction related Sudden Cardiac Death (Death occuring before blood samples could be obtained, or at a time before the appearance of cardiac biomarkers in the blood.) Myocardial Infarction associated with PCI (in patients with normal baseline troponin values) Myocardial infarction associated with CABG (in patients with normal baseline troponin values,) Detection of rise and/or fall of cardiac biomarkers (preferably troponin) with at least one value * By convention, increases of biomarkers greater than 5 x 99'h Sudden, unexpected cardiac death, involving cardiac arrest, often with : * By convention, increases of biomarkers greater above the 99th percentile of the * Symptoms suggestive of than 3 x 99th percentile URL plus upper reference limit (URL) myocardial ischaemia, and percentile URL either new pathological together with evidence of myocardial ischaemia with at least accompanied by * New ST elevation, or new have been designated as Q waves or new LBBB, or angiographically one of the following: LBBB, and/or defining PCI- documented new graft * Symptoms of ischaemia * Evidence of fresh thrombus by related myocardial or native aery * ECG changes indicative of new coronary angiography and/or infarction. occlusion, or imaging ischaemia * Development of pathological Q waves in the ECG at autopsy, evidence of new loss of ble myocardium have been designated as defining CABG-related myocardial infarction. * Imaging evidence of new loss of ble myocardium or new regional wall motion abnormality.
