title: Acute coronary insufficiency with normal coronary arteriograms.
abstract: Two patients presenting with apparent symptomatic and electrocardiographic evidence of acute coronary insufficiency and found to have normal coronary arteriograms are documented. The patients remain symptom free at follow-up 9 and 14 months later although one requires 160 mg propranolol daily. The electrocardiographic, myocardial metabolic and haemodynamic data in 413 patients with angina and normal coronary arteriograms are reviewed and the suggested aetiologies documented. Follow-up of patients in these series indicates a good prognosis for symptom-free survival.
