Coronary Stenosis Clinical Trial
Official title:
Pronostic Impact of Flow Fraction Reserve on Intermediate Stenoses
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
