Abstract Funding Acknowledgements Type of funding sources: None. Background Patients with heart failure with reduced ejection fraction (HFrEF) who received implantable cardiac defibrillator (ICD) still remain at high risk due to pump failure and comorbid conditions. C-reactive protein to albumin ratio (CAR) may be of value for identifying those with high risk for mortality despite ICD implantation. Methods Those who were implanted ICD for HFrEF in our institution between 2009 and 2019 were included. CAR was calculated as ratio of C-reactive protein (CRP) to serum albumin concentration. Patients were grouped into tertiles in accordance to CAR at the time of implantation. After follow up of 48 ± 35 months, survival times of tertiles were compared by using Kaplan-Meier survival method. Results Thousand and eleven patients constituted study population. Ischemic cardiomyopathy was primary diagnosis in 92.3%. Of those 14.5% had died after discharge. Patients in tertile 3 (T3) had higher risk of appropriate shock (19.3% vs 23.7% vs 38.0%) and mortality (4.2% vs 11.0% vs 28.5%) compared to those in other tertiles. Multivariable analysis revealed that when patients in T1 were considered as reference, both those in T2 and T3 had independently higher risk of appropriate shocks and mortality. These effects were consistent in the unadjusted and adjusted multivariable models. Conclusion Among patients with HFrEF and ICD, elevated CAR increased the risk of appropriate device shock and mortality at long term.

Abstract Background In-stent restenosis (ISR) remains a potential problem and raises concerns about the long-term safety and efficacy of carotid artery stenting (CAS). As inflammation has a pivotal role in the pathogenesis of ISR, a novel and more sensitive inflammatory marker, CRP/albumin ratio (CAR) may be used to predict ISR in patients undergoing CAS. Purpose The present study aimed to assess the predictive value of preprocedural C-reactive protein/albumin ratio (CAR) for ISR after CAS. Method In this retrospective study, 206 patients who underwent successful CAS procedure in a tertiary heart centre were included. For each patient, both C-reactive protein (CRP) and serum albumin were determined before the index procedure. The CAR was calculated by dividing serum CRP by serum albumin level. The main end-point of the study was ISR during long-term follow-up. Results ISR developed in 34 (16.5%) out of 206 patients after a mean follow-up of 24.2±1.5 months. The CAR was significantly elevated in patients with ISR compared to those who were not (0.99 [1.3] vs. 0.15 [0.2], p<0.01, respectively). In a multivariate Cox regression analysis, the CAR was an independent predictor of ISR (HR: 1.85, 95% CI: 1.29–2.64, p<0.01). A ROC curve analysis revealed that the optimal value of CAR in predicting ISR was >0.53 with a sensitivity of 100% and a specificity of 97.1% [area under curve (AUC) 0.98, p<0.001]. Conclusion The present study demonstrated that CAR, a new inflammatory-based index, is a strong independent predictor of ISR after CAS. As a simple and easily accessible parameter, this index may be used for the assessment of ISR in patients who are treated with CAS. Funding Acknowledgement Type of funding source: None
