[|AI|]  Sorry for the loss... But every medical procedure has risk associated... With all care many times patient not survive... As your father was having coronary artery disease. many times these patient go on arrhythmia... Fast heart rate... His surgery done in emergency say more chances of death related risk. Even angiography also has 1% risk which increases with age. Heart disease., Unstable patient. Only treating doctor can tell you exact what happened... Take care
