The authors report fifty-nine cases of non-transmural myocardial infarction. The diagnosis was made on the basis of clinical electrocardiographic data and enzyme changes. The clinical course was characterized by several chest pain attacks; a transmural myocardial infarction occurred in four patients a few days after admission. Out of fifty-five patients, followed for a nineteen - months period, six died, thirty-one were asymptomatic and fourteen complained of angina. In the last group, chest pain was generally present before the non-transumural myocardial infarction. The ECG were within normal limits in thirty-seven patients. The coronarographic patterns found in fifteen patients are also described and discussed.
We thought chest pain associated with ST segment elevation during exercise test in patients with not significant coronary lesions could be related to coronary spasm. Three patients with mild coronary obstructive lesions underwent coronary arteriography during exercise test. In two patients this hypotesis was supported by angiographic documentation of the coronary spasm.
The clinical, electrocardiographic, coronarographic and hemodynamic findings in thirty-one patients with left coronary artery stenosis were compared with those noted in patients with critical stenoses in all the three branches only. It was not possible to distinguish between the two groups of patients by comparing these results, and coronary arteriography is still the only valid diagnostic procedure.
