Frailty and coronary plaque characteristics on optical coherence tomography

The relationship between frailty and plaque characteristics is unclear and was investigated by optical coherence tomography (OCT) in this study. One hundred and four patients undergoing OCT before percutaneous coronary intervention were evaluated. Frailty was defined as a clinical frailty scale score of ≧6. Frailty was found in 16% of the patients (17/104). Compared with the nonfrail patients, frail patients showed significantly lower body mass...
