          Abstract

          Background  In patients with atrial fibrillation, the CHA 2 DS 2 -VAS C score guides stroke prevention using anticoagulants, but it is an imperfect score. Other potential risk factors such as renal failure, the type of atrial fibrillation, active smoking, cancer, sleep apnea or systemic inflammation have less well been investigated.

          Objective  To assess the impact of these factors on ischemic stroke risk in patients with non-valvular atrial fibrillation.

          Methods  On a population of 248 patients (124 patients with acute ischemic stroke and 124 controls), we performed a logistic regression to assess the impact of multiple non-classic risk factors for the prediction of acute ischemic stroke. Their impact on mortality was assessed by performing a survival analysis.

          Results  A high CHA 2 DS 2 -VASc score (OR 1.75; 95% CI 1.13–2.70; p = 0.032), treatment with anticoagulants (OR 0.19; 95% CI 0.07–0.51; p < 0.001) and permanent atrial fibrillation (OR 6.31; 95% CI 2.46–16.19; p < 0.001) were independently associated with acute ischemic stroke. Renal failure and chronic obstructive pulmonary disease predicted a higher mortality. After adjusting for age, sex, the CHA 2 DS 2 -VASc score and the use of anticoagulants, the only risk factor predictive for acute ischemic stroke was the permanent type of AF (OR: 8.0 [95% CI 2.5–25.5], p < 0.001).

          Conclusions  The CHA 2 DS 2 -VASc score, the absence of anticoagulants and the permanent type of atrial fibrillation were the main predictive factors for the occurrence of acute ischemic stroke. Larger studies are necessary for conclusive results about other factors.

          Resumo

          Antecedentes  Em pacientes com fibrilação atrial, o escore CHA2DS2-VASC orienta a prevenção de AVC com anticoagulantes, mas é um escore imperfeito. Outros fatores de risco potenciais, como insuficiência renal, o tipo de fibrilação atrial, tabagismo ativo, câncer, apnéia do sono ou inflamação sistêmica foram menos bem investigados.

          Objetivo  Avaliar o impacto desses fatores no risco de AVC isquêmico em pacientes com fibrilação atrial não valvular.

          Métodos  Em uma população de 248 pacientes (124 pacientes com AVC isquêmico agudo e 124 controles), realizamos uma regressão logística para avaliar o impacto de múltiplos fatores de risco não clássicos na predição de AVC isquêmico agudo. O seu impacto na mortalidade foi avaliado através da realização de uma análise de sobrevivência.

          Resultados  Escore CHA2DS2-VASc alto (OR 1,75; IC 95% 1,13–2,70; p = 0,032), tratamento com anticoagulantes (OR 0,19; IC 95% 0,07–0,51; p < 0,001) e fibrilação atrial permanente (OR 6,31; 95% CI 2,46–16,19; p < 0,001) foram independentemente associados ao AVC isquêmico agudo. Insuficiência renal e doença pulmonar obstrutiva crônica previram maior mortalidade. Após ajuste para idade, sexo, pontuação CHA2DS2-VASc e uso de anticoagulantes, o único fator de risco preditivo para AVC isquêmico agudo foi o tipo permanente de FA (OR: 8,0 [IC 95% 2,5–25,5], p < 0,001).

          Conclusões  O escore CHA2DS2-VASc, a ausência de anticoagulantes e o tipo permanente de fibrilação atrial foram os principais fatores preditivos para a ocorrência de AVC isquêmico agudo. Estudos maiores são necessários para resultados conclusivos sobre outros fatores.

            Refining clinical risk stratification for predicting stroke and thromboembolism in atrial fibrillation using a novel risk factor-based approach: the euro heart survey on atrial fibrillation.

            Contemporary clinical risk stratification schemata for predicting stroke and thromboembolism (TE) in patients with atrial fibrillation (AF) are largely derived from risk factors identified from trial cohorts. Thus, many potential risk factors have not been included. We refined the 2006 Birmingham/National Institute for Health and Clinical Excellence (NICE) stroke risk stratification schema into a risk factor-based approach by reclassifying and/or incorporating additional new risk factors where relevant. This schema was then compared with existing stroke risk stratification schema in a real-world cohort of patients with AF (n = 1,084) from the Euro Heart Survey for AF. Risk categorization differed widely between the different schemes compared. Patients classified as high risk ranged from 10.2% with the Framingham schema to 75.7% with the Birmingham 2009 schema. The classic CHADS(2) (Congestive heart failure, Hypertension, Age > 75, Diabetes, prior Stroke/transient ischemic attack) schema categorized the largest proportion (61.9%) into the intermediate-risk strata, whereas the Birmingham 2009 schema classified 15.1% into this category. The Birmingham 2009 schema classified only 9.2% as low risk, whereas the Framingham scheme categorized 48.3% as low risk. Calculated C-statistics suggested modest predictive value of all schema for TE. The Birmingham 2009 schema fared marginally better (C-statistic, 0.606) than CHADS(2). However, those classified as low risk by the Birmingham 2009 and NICE schema were truly low risk with no TE events recorded, whereas TE events occurred in 1.4% of low-risk CHADS(2) subjects. When expressed as a scoring system, the Birmingham 2009 schema (CHA(2)DS(2)-VASc acronym) showed an increase in TE rate with increasing scores (P value for trend = .003). Our novel, simple stroke risk stratification schema, based on a risk factor approach, provides some improvement in predictive value for TE over the CHADS(2) schema, with low event rates in low-risk subjects and the classification of only a small proportion of subjects into the intermediate-risk category. This schema could improve our approach to stroke risk stratification in patients with AF.
