Acute coronary insufficiency with normal coronary arteriograms
Insights
Patients with angina and normal coronary arteriograms often experience symptom-free survival. Further review of electrocardiographic, metabolic, and hemodynamic data suggests various potential causes for their condition, indicating a generally good prognosis.
Area of Science:
- Cardiology
- Internal Medicine
Background:
- Acute coronary insufficiency symptoms and electrocardiographic changes can occur despite normal coronary arteriograms.
- Understanding the underlying causes and prognosis for these patients is crucial for effective management.
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.
