ABSTRACT
OBJECTIVES: This observational, cross-sectional study based aimed to test whether heart failure (HF)-disease management program (DMP) components are influencing care and clinical decision-making in Brazil. METHODS: The survey respondents were cardiologists recommended by experts in the field and invited to participate in the survey via printed form or email. The survey consisted of 29 questions addressing site demographics, public versus private infrastructure, HF baseline data of patients, clinical management of HF, performance indicators, and perceptions about HF treatment. RESULTS: Data were obtained from 98 centers (58% public and 42% private practice) distributed across Brazil. Public HF-DMPs compared to private HF-DMP were associated with a higher percentage of HF-DMP-dedicated services (79% vs 24%; OR: 12, 95% CI: 94-34), multidisciplinary HF (MHF)-DMP [84% vs 65%; OR: 3; 95% CI: 1-8), HF educational programs (49% vs 18%; OR: 4; 95% CI: 1-2), written instructions before hospital discharge (83% vs 76%; OR: 1; 95% CI: 0-5), rehabilitation (69% vs 39%; OR: 3; 95% CI: 1-9), monitoring (44% vs 29%; OR: 2; 95% CI: 1-5), guideline-directed medical therapy-HF use (94% vs 85%; OR: 3; 95% CI: 0-15), and less B-type natriuretic peptide (BNP) dosage (73% vs 88%; OR: 3; 95% CI: 1-9), and key performance indicators (37% vs 60%; OR: 3; 95% CI: 1-7). In comparison to non- MHF-DMP, MHF-DMP was associated with more educational initiatives (42% vs 6%; OR: 12; 95% CI: 1-97), written instructions (83% vs 68%; OR: 2: 95% CI: 1-7), rehabilitation (69% vs 17%; OR: 11; 95% CI: 3-44), monitoring (47% vs 6%; OR: 14; 95% CI: 2-115), GDMT-HF (92% vs 83%; OR: 3; 95% CI: 0-15). In addition, there were less use of BNP as a biomarker (70% vs 84%; OR: 2; 95% CI: 1-8) and key performance indicators (35% vs 51%; OR: 2; 95% CI: 91,6) in the non-MHF group. Physicians considered changing or introducing new medications mostly when patients were hospitalized or when observing worsening disease and/or symptoms. Adherence to drug treatment and non-drug treatment factors were the greatest medical problems associated with HF treatment. CONCLUSION: HF-DMPs are highly heterogeneous. New strategies for HF care should consider the present study highlights and clinical decision-making processes to improve HF patient care.

FUNDAMENTO: A fibrilação atrial é um fator de risco controverso para demência. OBJETIVO: O objetivo deste estudo é avaliar a associação entre fibrilação atrial e demência em participantes do São Paulo Ageing & Health. MÉTODOS: O São Paulo Ageing & Health é um estudo transversal, de base populacional, de idosos residentes em um uma região de baixa renda da cidade de São Paulo, Brasil. Diagnóstico de demência foi realizado de acordo com o protocolo do grupo 10/66, com base em critérios do Manual de Diagnóstico e Estatística das Perturbações Mentais (DSM-IV). O diagnóstico de fibrilação atrial foi feito por eletrocardiograma de 12 derivações, avaliado por dois cardiologistas. Dados demográficos e de fatores de risco cardiovasculares também foram obtidos. RESULTADOS: A demência foi diagnosticada em 66 (4,3%) e fibrilação atrial em 36 (2,4%) de 1.524 participantes com um eletrocardiograma válido. A razão de chances bruta para demência em participantes com fibrilação atrial foi 2,8 (intervalo de confiança [IC] 95%: 1,0-8,1; p = 0,06) em comparação com indivíduos sem fibrilação atrial. Relação positiva foi encontrada em mulheres (RC 4,2; IC 95%: 1,2-15,1; p = 0,03). Após ajuste para idade, no entanto, essa associação tornou-se não significativa (RC 2,2, IC 95%: 0,6-8,9; p = 0,26). CONCLUSÃO: Não houve associação independente entre a fibrilação atrial e demência nessa amostra. A prevalência da fibrilação atrial pode ser baixa nesta população em virtude da mortalidade cardiovascular prematura.
BACKGROUND: Atrial fibrillation (AF) is a controversial risk factor for dementia. OBJECTIVE: The objective of this study was to assess the association between AF and dementia in the "Sao Paulo Ageing & Health" (SPAH) study participants. METHODS: SPAH is a cross-sectional, population-based study of elderly people living in a deprived neighborhood in Sao Paulo, Brazil. Dementia diagnosis was performed according to the 10/66 study group protocol based on Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) criteria. Diagnosis of AF was made using a 12-lead electrocardiogram (ECG) recording, which was assessed by two cardiologists. Data on demographics and cardiovascular risk factors were also obtained. RESULTS: Dementia was diagnosed in 66 (4.3%) and AF in 36 (2.4%) of 1,524 participants with a valid ECG. The crude odds ratio (OR) for dementia in participants with AF was 2.8 (95% confidence interval [CI]: 1.0-8.1; p=0.06) compared with individuals without AF. When analyzing data according to sex, a positive relationship was found in women (OR 4.2; 95% CI: 1.24-15.1; p=0.03). After age-adjustment, however, this association was no longer significant (OR 2.2; 95% CI: 0.6-8.9; p=0.26). CONCLUSION: There was no independent association between AF and dementia in this sample. The prevalence of AF may be low in this population owing to premature cardiovascular death.
