Background: The CHADS-VASC score does not incorporate renal dysfunction in stroke risk assessment in patients with atrial fibrillation and the prevalence of atrial fibrillation, atrial flutter, and cerebrovascular accidents (CVA) in patients with concurrent CHF and CKD is not well investigated. Objective: Evaluate the prevalence of history of stroke, atrial fibrillation, atrial flutter in patients with CHF and CKD. Methods: Data from the single institution Get With The Guidelines- Heart Failure (GWG-HF) cohort of 2938 consecutive inpatients with known GFR was utilized. CHADS-VASC score was calculated from the GWG-HF variables. Chronic kidney disease (CKD) was defined as GFR <60 ml/min. Results: An overwhelming majority (95%) of GWG-HF patients had elevated >1 CHADS-VASC score, which was also significantly more common in patients with CKD (97.6% vs. 91.7% in patients without CKD, p<0.0001). Average CHADS-VASC score was also significantly increased in patients with CKD (4+/-1.3 vs. 3.3+/-1.4, p<0.0001). Furthermore, CKD was associated with increased prevalence of atrial fibrillation and/or flutter (45.6% vs. 35.3%, p<0.0001) and stroke history (17.5% vs. 12.3%, p=0.002). When stroke and TIA histories were removed from the CHADS-VASC score ("CHAD-VASC score"), the remaining variables were strongly predictive of stroke or TIA (14.2% vs. 3.8%, p<0.0001). In multivariate logistic regression analysis, both CHAD-VASC score (OR 2.6, 95%CI 1.3-5.4, p=0.009) and CKD (OR 1.5, 95%CI 1.2-1.8, p=0.001) were associated significantly increased odds of prior stroke or TIA. Conclusions: In patients admitted with heart failure, CKD is associated with increased prevalence of atrial fibrillation or atrial flutter as well as increased prevalence of CVA/TIA. Further prospective studies are warranted to examine whether CKD history should be included in stroke risk assessment in patients with atrial fibrillation or atrial flutter, in conjunction with existing risk assessment frameworks.

Discriminatory Performance

SummaryMany of the risk factors for stroke in atrial fibrillation (AF) are also important risk factors for bleeding. We tested the hypothesis that the CHADS2 and CHA2DS2-VASc scores (used for stroke risk assessment) could be used to predict serious bleeding, and that these scores would compare well against the HAS-BLED score, which is a specific risk score designed for bleeding risk assessment. From the AMADEUS trial, we focused on the trial’s primary safety outcome for serious bleeding, which was “any clinically relevant bleeding”. The predictive value of HAS-BLED/CHADS2/CHA2DS2-VASc were compared by area under the curve (AUC, a measure of the c-index) and the Net Reclassification Improvement (NRI). Of 2,293 patients on VKA, 251 (11%) experienced at least one episode of “any clinically relevant bleeding” during an average 429 days follow up period. Incidence of “any clinically relevant bleeding” rose with increasing HAS-BLED/CHADS2/CHA2DS2-VASc scores, but was statistically significant only for HAS-BLED (p<0.0001). Only HAS-BLED demonstrated significant discriminatory performance for “any clinically relevant bleeding” (AUC 0.60, p<0.0001). There were significant AUC-differences between HAS-BLED (which had the highest AUC) and both CHADS2 (p<0.001) and CHA2DS2VASc (p=0.001). The HAS-BLED score also demonstrated significant NRI for the outcome of “any clinically relevant bleeding” when compared with CHADS2 (p=0.001) and CHA2DS2-VASc (p=0.04). In conclusion, the HAS-BLED score demonstrated significant discriminatory performance for “any clinically relevant bleeding” in anticoagulated patients with AF, whilst the CHADS2 and CHA2DS2-VASc scores did not. Bleeding risk assessment should be made using a specific bleeding risk score such as HAS-BLED, and the stroke risk scores such as CHADS2 or CHA2DS2-VASc scores should not be used.
