Kurisu et al identified changes in the electrocardiogram associated with mortality following an acute myocardial infarction (AMI) involving the left main coronary artery. These can help to identify a patient who may benefit from more aggressive management. The authors are from Hiroshima City Hospital in Hiroshima, Japan.
Patient selection: AMI associated with occlusion of the left main coronary artery
Outcome: death within 30 days of the AMI
ECG findings associated with death within 30 days of the AMI:
(1) right bundle branch block
(2) left anterior fascicular block
(3) ST segment elevation >= 0.1 mV in both aVR and aVL
Survivors were more likely to have ST segment depression >= 0.1 mV in V5.
