The intermediate coronary stenoses defined by a degree of stenosis from 40 to 70 % are frequent. The Flow Fraction Reserve (FFR), realized during coronarography, is an hemodynamic evaluation by the functional impact measuring the loss of load in upstream / approval of the stenosis inthe basal state and in situation of hyperemia led by adenosine. Further to the study FAME, the threshold of definition of the significant character of one Stenosis was fixed for a value of FFR = 0,80. However, the impact forecasts intermediate values badly known rest.

We hypothetized that coronary stenosis associated with borderline values of FFR 0.81-0.85 were associated with a higher rate of clinical events than those with a FFR >0.85

Inclusion Criteria:

• patient with FFR> 0,80 between september 2012 till december 2016

Exclusion Criteria:

• refusal of participation

patient underwent FFR during angiography between 2012 september and december 2016
