Chen T, et al. - In this study with 506 consecutive coronary artery disease (CAD) patients, researchers examined the link between fibrinogen-to-albumin ratio (FAR) and in-stent restenosis (ISR) in patients who underwent DES implantation. The participants were split into ISR group (n = 125) and no-ISR group (n = 381). Via multivariate logistic regression analysis, experts assessed significant factors related to ISR. Significantly higher FAR level was detected in the ISR group vs no-ISR group. In multivariate analysis, a significant link of FAR, albumin and diabetes mellitus with ISR was revealed. Overall, experts identified a significant association of FAR with ISR development among CAD patients receiving percutaneous coronary intervention with DES implantation.
