Coronary artery stenoses more often overestimated in older patients: Angiographic stenosis overestimation in elderly.

Background: Angiographic overestimation of coronary artery stenosis severity may result in unnecessary revascularization and is possibly more prevalent with increasing age.

Aim: To identify whether age is an independent clinical predictor for angiographic overestimation of a coronary artery stenosis.

Methods: Fractional flow reserve (FFR) of 335 coronary lesions was performed in 260 consecutive patients with stable coronary artery disease (CAD).
