Use of the 11-Item Modified Frailty Index to Determine Accurate Prognosis and Revascularization Strategy in Patients Undergoing Vascular Bypass Surgery for Intermittent Claudication.

Background: In cases of intermittent claudication (IC) where traditionally noninvasive management yields unsatisfactory results, revascularization strategy in IC patients is generally decided based on anatomical considerations and the availability of a saphenous vein graft. Life expectancy should also be considered. This study aimed to investigate the relationship between the 11-item modified frailty index (mFI-11) and the overall survival (OS) in patients with IC who underwent vascular bypass surgery to facilitate revascularization strategy selection.
