ABSTRACT
Myocardial thallium 201 tomography was performed in 112 patients admitted to hospital in the acute stage of a first myocardial infarction. Our quantification method for the myocardial lacuna, validated by animal studies, is described. The necrotic mass evaluated is compared with enzymatic (CPK) (r = 0.89) and angiographic (r = 0.78) quantitative assessments. Thallium 201 tomographic quantification has an unquestionable prognostic value. Thus, among patients whose infarcted mass represented more than 25% of the total myocardial mass, 71% died or developed severe heart failure. Conversely, 93% of patients with a small infarct (less than 20% of total myocardial mass) were asymptomatic on a 24-month follow-up. Myocardial thallium 201 tomography provides a reasonable quantification of the infarct. Its prognostic value seems to be satisfactory.
