Acute myocardial infarction with a non-diagnostic electrocardiogram. Case presentation and overview.
The clinical presentation of a young hypertensive White man with acute high lateral non-transmural myocardial infarction (MI) is documented. This diagnosis was established on the grounds of a history of chest pain, elevated serial serum enzyme levels, technetium-99m pyrophosphate ('hot-spot') scintigraphy, exercise thallium-201 ('cold-spot') scanning, left ventricular cine angiography and selective coronary arteriography. Daily resting 12-lead ECGs failed to demonstrate unequivocal features of acute non-transmural subendocardial MI. The diagnostic difficulties facing the clinician in a case of acute MI associated with a non-diagnostic ECG are stressed, and the ECG features of acute subendocardial MI are reviewed.
