Abstract

<h4>Background</h4>Chronic kidney disease (CKD) is highly prevalent in atrial fibrillation (AF) patients and associated with an increased risk of adverse outcomes. Our objectives were to study clinical features associated with CKD in AF patients and the impact of CKD on anticoagulation control, as reflected by time in therapeutic range (TTR). We also determined the impact of CKD and TTR in predicting adverse outcomes.<h4>Methods and results</h4>We analysed pooled datasets from SPORTIF III and V trials, including 3646 patients assigned to warfarin with data on renal function. CKD (creatinine clearance <60ml/min) was present in 952 (26%) patients. TTR was higher in patients with normal renal function compared to those with CKD (p<0.001). On logistic analysis, chronic AF and male sex were associated with TTR>70%, whilst diabetes mellitus, aspirin use and CKD were inversely associated with TTR>70%. On Cox regression analysis, CKD was an independent predictor for stroke (p=0.006) and death (p<0.001). TTR>70% was independently associated with a lower risk of stroke (p=0.024), death (p=0.001) and major bleeding (p=0.001).<h4>Conclusions</h4>CKD is highly prevalent amongst AF patients and a risk factor for stroke and death. Adjusting for CKD, good quality anticoagulation control (TTR>70%) was an independent predictor for lower risks of stroke, death and major bleeding.
