Subendocardial myocardial infarction. N. Bayley, D. Hunt, C. Penington and J. G. Sloman, Aust. N.Z. J. Med., 1982, 12, pp. 166–169. Sixty–one consecutive patients with acute subendocardial myocardial infarction (SEAMI) and 223 consecutive patients with transmural infarction (TMI) seen in a coronary care unit were followed for one year. All patients were less than 70 years of age. The patients with SEAMI had a higher frequency of previous infarction (34% vs 21%, p< 0–025), less cardiac failure (44% vs 65%, p<0005), and were more often free from arrhythmias (61 % vs 31%, p<0001) than patients with TMI. Hospital mortality was less in patients with SEAMI (0% vs 8%, p < 0 05) but total mortality to one year was similar (15% vs 17%). Amongst patients with SEAMI, two died within two weeks of infarction but all other deaths occurred at least six weeks after infarction.Patients with SEAMI and a history of previous infarction had a higher one year mortality than patients without such a history (29% vs 7%, p < 0 05). Coronary angiography with a view to coronary artery surgery should be considered in the former group.
