Among 10 % of all patients presenting with non ST elevation acute coronary syndromes (ACS), coronary angiography do not show non lesions at all (50 % ) or mild atheromatous stenosis (50 % ). ACS without angiographic stenosis are more prevalent in female sex and young patients but can be seen in older ones and in men. Pathogenic mechanisms include acute evolution of vulnerable non-significant plaques and endothelial dysfunction. Inhospital and mean term prognosis is not as benign as expected. Six months deaths and myocardial infarction incidence is around 6 % . Numerous rehospitalizations due to ischemic recurrences are also very often seen. Therefore, such surprising coronary angiograms do not preclude a fair follow-up. These patients need a careful therapeutic strategy.
