Question: 1 / 400

True or False: Values greater than .75-.80 for FFR indicate a significant stenosis.

True

False

The statement is false because a Fractional Flow Reserve (FFR) value greater than 0.75-0.80 typically indicates a non-significant stenosis, meaning that the coronary artery narrowing is unlikely to be causing a substantial limitation to blood flow during peak exercise conditions. Generally, an FFR value below 0.80 is used as a threshold to identify significant stenosis, where values below this level suggest that the lesion may be functionally significant and may warrant intervention, such as angioplasty or stent placement.

A value between 0.75 and 0.80 is discordant and does not consistently predict the significance of stenosis. The interpretation of FFR also takes into account clinical context, including the patient's symptoms and overall cardiovascular status. Understanding FFR helps in guiding the management of patients with coronary artery disease and determining the necessity for revascularization procedures.
