[Angina and "normal coronarography" results: diagnostic approach and future perspectives (author's transl)].

Patients with angina but with "normal coronarography" results, are not a rare finding during angiographic investigations, more especially in the case of women. The authors review the clinical, electrical, hemodynamic and metabolic characteristics of these cases, and discuss the principal known etiologies, and limits of "normality" with respect to coronary artery angiography results.
