  • Title: [The isoproterenol test in the electrocardiographic diagnosis of coronary insufficiency. Experience in 100 cases of ischemic cardiopathy].
    Author: Mazzoni S, Jaeger M, Codreanu R, Rivier JL.
    Journal: G Ital Cardiol; 1975; 5(5):696-703. PubMed ID: 1205042.
    Abstract:
    Intravenous infusion of 10 to 30 gamma/min. of Isuprel for 3 to 7 minutes is accurate in diagnosing coronary disease in at least 80% of cases in our series of 100 patients with segmental coronary artery stenoses of 50% or more, demonstrated by coronary angiography. By comparing these 100 patients with a control group of 30 healthy subjects we can state that the late "ST" segment changes (persisting or appearing 3 minutes after stopping the infusion) are typical of coronary insufficiency. In patients without previous infarction, coronary insufficiency is expressed by a horizontal "ST" depression of 1 mm or more. In patients with previous infarction we observed either an "ST" depression or an "ST" elevation. The "ST" elevation, never observed in the control group, seems to have a different significance depending on whether or not a previous myocardial infarction has occurred. If there was no previous necrosis, severe coronary artery disease seems to be suggested and is a bad prognostic sign. This is not so if the patient has previously presented a myocardial infarction.
