Abstract
Summary: A comparison of nontransmural and transmural myocardial infarction. J. Boxall and A. Saltups, Aust. N.Z. J. Med., 1980, 10, pp. 176–179.This report compares the past history, hospital course and follow‐up of 70 patients with nontransmural myocardial infarction compared to 259 patients with transmural myocardial infarctionThe pre‐infarction history in the two groups is similar with respect to angina and infarction. The hospital course for non‐transmural myocardial infarction is not a guide for future cardiac events and the post‐hospital prognosis in the two groups is similar. Nontransmural myocardial infarction has a lower hospital mortality (PP< 0.05).The study demonstrates that myocardial infarction without development of q waves does not have an unfavourable long term outlook when compared to transmural infarction. This finding is contrary to reports which suggest a poor prognosis and recommend early coronary anteriography with a view to aorto‐coronary bypass in patients with nontransmural infarction
