[Prognostic value of normal coronary angiography].
Coronary angiography is the "gold standard" for coronary artery disease (CAD). It is considered either normal or subnormal without any lesion (endocoronary echography often demonstrates atheroma), or in presence of a < 50% stenosis. Nevertheless, the risk of plaque rupture is not well correlated with the degree stenosis. Despite the frequent presence of non-significant atheroma, is a normal coronarography really of a good prognosis? Between January and September 1997, 136 of 600 (22.6%) angiographies were considered as normal. The indications were: "CAD suspicion" (n = 77), "preoperative angiography of valvulopathy" (n = 38), and "angioplasty control" (n = 22). The arteries were strictly normal for 86 patients (63%) and a < 50% stenosis was found in 50 patients (37%); 108 patients (80.1%) were followed for 18 +/- 3 months: eight non coronary deaths were reported: four postoperative deaths in "valvular group", two pulmonary embolisms and two pulmonary neoplasm's in "CAD suspicion group". No myocardial infarction was reported and one unstable angina was documented. Despite the frequency of non-significant atheroma, an acute coronary syndrome exceptionally complicates a "normal" coronarography.
