cold cardioplegic techniques have decreased the risks of ischemic myocardial damage during aortic clamping , but reperfusion damage can still occur when there is poor cardioplegic distribution ( that is , coronary artery disease ) or in hearts that have suffered ischemic damage before extracorporeal circulation is started ( such as extending myocardial infarction , cardiogenic shock and the like ) .
