Why Are Outcomes Different for Registry Patients Enrolled Prospectively and Retrospectively? Insights from the Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF).

Background: Retrospective and prospective observational studies are designed to reflect real-world evidence on clinical practice, but can yield conflicting results. The GARFIELD-AF Registry includes both methods of enrolment and allows analysis of differences in patient characteristics and outcomes that may result. Methods and Results: Patients with atrial fibrillation (AF) and ≥1 risk factor for stroke at diagnosis of AF were recruited either retrospectively (n = 5069) or prospectively (n = 5501) from 19 countries and then followed prospectively. The retrospectively enrolled cohort comprised patients with established AF (for a least 6, and up to 24 months before enrolment), who were identified retrospectively (and baseline and partial follow-up data were collected from the emedical records) and then followed prospectively between 0-18 months (such that the total time of follow-up was 24 months; data collection Dec-2009 and Oct-2010). In the prospectively enrolled cohort, patients with newly diagnosed AF (≤6 weeks after diagnosis) were recruited between Mar-2010 and Oct-2011 and were followed for 24 months after enrolment. Differences between the cohorts were observed in clinical characteristics, including type of AF, stroke prevention strategies, and event rates. More patients in the retrospectively identified cohort received vitamin K antagonists (62.1% vs. 53.2%) and fewer received non-vitamin K oral anticoagulants (1.8% vs . 4.2%). All-cause mortality rates per 100 person-years during the prospective follow-up (starting the first study visit up to 1 year) were significantly lower in the retrospective than prospectively identified cohort (3.04 [95% CI 2.51 to 3.67] vs . 4.05 [95% CI 3.53 to 4.63]; p = 0.016). Conclusions: Interpretations of data from registries that aim to evaluate the characteristics and outcomes of patients with AF must take account of differences in registry design and the impact of recall bias and survivorship bias that is incurred with retrospective enrolment.

Risk profiles and one-year outcomes of patients with newly diagnosed atrial fibrillation in India: Insights from the GARFIELD-AF Registry.

BACKGROUND: The Global Anticoagulant Registry in the FIELD-Atrial Fibrillation (GARFIELD-AF) is an ongoing prospective noninterventional registry, which is providing important information on the baseline characteristics, treatment patterns, and 1-year outcomes in patients with newly diagnosed non-valvular atrial fibrillation (NVAF). This report describes data from Indian patients recruited in this registry. METHODS AND RESULTS: A total of 52,014 patients with newly diagnosed AF were enrolled globally; of these, 1388 patients were recruited from 26 sites within India (2012-2016). In India, the mean age was 65.8 years at diagnosis of NVAF. Hypertension was the most prevalent risk factor for AF, present in 68.5% of patients from India and in 76.3% of patients globally (P < 0.001). Diabetes and coronary artery disease (CAD) were prevalent in 36.2% and 28.1% of patients as compared with global prevalence of 22.2% and 21.6%, respectively (P < 0.001 for both). Antiplatelet therapy was the most common antithrombotic treatment in India. With increasing stroke risk, however, patients were more likely to receive oral anticoagulant therapy [mainly vitamin K antagonist (VKA)], but average international normalized ratio (INR) was lower among Indian patients [median INR value 1.6 (interquartile range {IQR}: 1.3-2.3) versus 2.3 (IQR 1.8-2.8) (P < 0.001)]. Compared with other countries, patients from India had markedly higher rates of all-cause mortality [7.68 per 100 person-years (95% confidence interval 6.32-9.35) vs 4.34 (4.16-4.53), P < 0.0001], while rates of stroke/systemic embolism and major bleeding were lower after 1 year of follow-up. CONCLUSION: Compared to previously published registries from India, the GARFIELD-AF registry describes clinical profiles and outcomes in Indian patients with AF of a different etiology. The registry data show that compared to the rest of the world, Indian AF patients are younger in age and have more diabetes and CAD. Patients with a higher stroke risk are more likely to receive anticoagulation therapy with VKA but are underdosed compared with the global average in the GARFIELD-AF.

Cardiomiopatia chagásica: prognóstico no perfil clínico-hemodinâmico C Cardiomiopatía chagásica: pronóstico en el perfil clínico-hemodinámico C Chagas cardiomyopathy: prognosis in clinical and hemodynamic profile C

FUNDAMENTO: Os pacientes com insuficiência cardíaca (IC) que são internados apresentando má perfusão e congestão (perfil clínico-hemodinâmico C) constituem o grupo que evolui com pior prognóstico na IC descompensada. Entretanto, há pouca informação na literatura se a etiologia da cardiopatia influencia na evolução dos pacientes na fase avançada. OBJETIVO: Avaliar a evolução dos pacientes que se internaram com perfil clínico-hemodinâmico C e verificar o papel da etiologia nesta fase. MÉTODOS: Um estudo de coorte foi realizado incluindo pacientes com fração de ejeção do ventrículo esquerdo (FEVE) < 45,0%, classe funcional IV e internação hospitalar apresentando perfil clínico-hemodinâmico C. O grupo foi dividido em pacientes portadores de cardiomiopatia chagásica (Ch) e não chagásica (NCh). Para análise estatística foram utilizados os testes t de Student, exato de Fisher, qui-quadrado e o programa SPSS. O significante de p < 0,05 foi considerado. RESULTADOS: Cem pacientes, com idade média de 57,6 ± 15,1 anos e FEVE média de 23,8 ± 8,5%, foram incluídos. Dentre os pacientes estudados, 33,0% eram chagásicos e, na comparação com os NCh, apresentaram menor pressão arterial sistólica (Ch 89,3 ± 17,1 mmHg versus NCh 98,8 ± 21,7 mmHg; p = 0,03) e menor idade média - Ch 52,9 ± 14,5 anos versus NCh 59,8 ± 14,9 anos; p = 0,03). Durante o acompanhamento de 25 meses, a mortalidade foi de 66,7% nos Ch e de 37,3% nos NCh (p = 0,019). A etiologia chagásica foi um marcador independente de mau prognóstico na análise multivariada com razão de risco de 2,75 (IC 95,0%; 1,35 - 5,63). CONCLUSÃO: Nos pacientes com IC avançada, a etiologia chagásica é um importante preditor de pior prognóstico.<br>FUNDAMENTO: Los pacientes con insuficiencia cardíaca (IC) que son internados presentando mala perfusión y congestión (perfil clínico-hemodinámico C) constituyen el grupo que evoluciona con peor pronóstico en la IC descompensada. Mientras tanto, hay poca información en la literatura sobre si la etiología de la cardiopatía influencia en la evolución de los pacientes en la fase avanzada. OBJETIVO: Evaluar la evolución de los pacientes que se internaron con perfil clínico-hemodinámico C y verificar el papel de la etiología en esta fase. MÉTODOS: Un estudio de cohorte fue realizado incluyendo pacientes con fracción de eyección del ventrículo izquierdo (FEVI) < 45,0%, clase funcional IV e internación hospitalaria presentando perfil clínico-hemodinámico C. El grupo fue dividido en pacientes portadores de cardiomiopatía chagásica (Ch) y no chagásica (NCh). Para análisis estadístico fueron utilizados los test t de Student, exacto de Fisher, qui-cuadrado y el programa SPSS. El significante de p < 0,05 fue considerado. RESULTADOS: Cien pacientes, con edad media de 57,6 ± 15,1 años y FEVI media de 23,8 ± 8,5%, fueron incluidos. Entre los pacientes estudiados, 33,0% eran chagásicos y, en la comparación con los NCh, presentaron menor presión arterial sistólica (Ch 89,3 ± 17,1 mmHg versus NCh 98,8 ± 21,7 mmHg; p = 0,03) y menor edad media - Ch 52,9 ± 14,5 años versus NCh 59,8 ± 14,9 años; p = 0,03). Durante el control de 25 meses, la mortalidad fue de 66,7% en los Ch y de 37,3% en los NCh (p = 0,019). La etiología chagásica fue un marcador independiente de mal pronóstico en el análisis multivariado con razón de riesgo de 2,75 (IC 95,0%; 1,35 - 5,63). CONCLUSIÓN: En los pacientes con IC avanzada, la etiología chagásica es un importante predictor de peor pronóstico.<br>BACKGROUND: Patients with heart failure (HF) who are admitted showing poor perfusion and congestion (clinical-hemodynamic profile C) are the group that evolves with the worst prognosis in decompensated heart failure. However, there is little information in literature on the etiology of cardiopathy influences the outcome of patients in advanced stage. OBJECTIVE: To assess the outcome of patients admitted with clinical and hemodynamic profile C and verify the role of the etiology in this phase. METHODS: A cohort study was performed including patients with left ventricle ejection fraction (LVEF) < 45.0%, functional class IV and hospitalization presenting clinical-hemodynamic profile C. The group was divided into patients with chagasic (Ch) and non chagasic (NCh) cardiomyopathy. Statistical analysis used Student t test, Fisher exact test, chi-square and SPSS tests. The significance of p < 0.05 was considered. RESULTS: One hundred patients, with mean age 57.6 ± 15.1 years and mean LVEF of 23.8 ± 8.5%, were included. Among the patients studied, 33.0% were chagasic and, in comparison with NCh, had lower systolic blood pressure (Ch 89.3 ± 17.1 mmHg versus NCh 98.8 ± 21.7 mmHg, p = 0.03 ) and lowest average age - Ch 52.9 ± 14.5 years versus NCh 59.8 ± 14.9 years, p = 0.03). During follow-up of 25 months, mortality was 66.7% for Ch and 37.3% in NCh (p = 0.019). The Chagas disease etiology was an independent marker of poor prognosis in multivariate analysis with risk ratio of 2.75 (HF 95.0%, from 1.35 to 5.63). CONCLUSION: In patients with advanced HF, Chagas disease is an important predictor of the worst prognosis

Adición de bloqueante del receptor de angiotensina II en la insuficiencia cardiaca descompensada

FUNDAMENTO: Durante a descompensação da insuficiência cardíaca, ocorre uma intensa ativação do sistema renina-angiotensina-aldosterona, entretanto, o uso de inibidor da enzima de conversão de angiotensina (IECA) não pode bloqueá-lo completamente. De outro modo, a adição de bloqueador do receptor de angiotensina II (BRA) pode ser útil quando ocorre a dependência de inotrópico. Avaliamos a eficiência da associação BRA-IECA para retirada da dobutamina na insuficiência cardíaca avançada e descompensada. OBJETIVO: Avaliar a eficácia da associação de bloqueador do receptor AT1 de angiotensina II ao inibidor de enzima de conversão, para a retirada da dobutamina em pacientes com dependência de suporte inotrópico decorrente da descompensação aguda da insuficiência cardíaca crônica. MÉTODOS: Em um estudo caso-controle (N = 24), selecionamos pacientes internados por descompensação da insuficiência cardíaca e com uso por mais de 15 dias de dobutamina, ou uma ou mais tentativas sem sucesso de retirada; dose otimizada de IECA; e FEVE < 0,45. Os pacientes então receberam adicionalmente BRA (n = 12) ou não (controle, n = 12). O desfecho foi o sucesso na retirada da dobutamina, avaliado pela regressão logística, com p < 0,05. RESULTADOS: A fração de ejeção foi de 0,25, e a idade de 53 anos, com dose de dobutamina de 10,7 &#956;g/kg.min. O sucesso na retirada de dobutamina ocorreu em oito pacientes do grupo BRA (67,7%), e em dois no grupo controle (16,7%). A "odds ratio" foi de 10,0 (intervalo de confiança de 95%:1,4 a 69,3; p = 0,02). A piora da função renal foi semelhante (grupo BRA: 42% vs. grupo controle: 67%, p = 0,129). CONCLUSÃO: Neste estudo piloto, a associação BRA-IECA foi relacionada ao sucesso na retirada da dobutamina, na insuficiência cardíaca avançada descompesada. A piora da função renal foi semelhante em ambos os grupos. Estudos adicionais são necessários para esclarecer o assunto.BACKGROUND: During heart failure (HF) decompensation, an intense activation of the renin-angiotensin-aldosterone system occurs; however, the use of angiotensin-converting enzyme inhibitor (ACEI) cannot block it completely. Otherwise, the addition of angiotensin II receptor blocker (ARB) can be useful when the inotropic dependence occurs. We evaluated the efficacy of the ARB-ACEI association on dobutamine withdrawal in advanced decompensated HF. OBJECTIVE: To assess the efficacy of association angiotensin receptor blocker - angiotensin converting enzyme inhibitor to withdraw the intravenous inotropic support in decompensated severe heart failure. METHODS: In a case-control study (N = 24), we selected patients admitted at the hospital due to HF that had been using dobutamine for more than 15 days, with one or more unsuccessful drug withdrawal attempts; optimized dose of ACEI and ejection fraction (EF) < 0.45. Then, the patients additionally received ARB (n=12) or not (control, n=12). The outcome was the successful dobutamine withdrawal, evaluated by logistic regression, with a p < 0.05. RESULTS: The EF was 0.25 and the age was 53 years, with a dobutamine dose of 10.7 &#956;g/kg.min. The successful drug withdrawal was observed in 8 patients from the ARB group (67.7%) and in 2 patients from the control group (16.7%). The odds ratio (OR) was 10.0 (95%CI: 1.4 to 69.3; p = 0.02). The worsening in renal function was similar (ARB group: 42% vs. control group: 67%; p=0.129). CONCLUSION: In this pilot study, the ARB-ACEI association was associated with successful dobutamine withdrawal in advanced decompensated heart failure. The worsening in renal function was similar in both groups. Further studies are necessary to clarify the issue.FUNDAMENTO: Durante la descompensación de la insuficiencia cardiaca, ocurre una intensa activación del sistema renina-angiotensina-aldosterona, sin embargo, el empleo de inhibidor de la enzima de conversión de angiotensina (IECA) no puede bloquearlo completamente.

OBJETIVO: Evaluar la eficacia de la asociación de bloqueante del receptor AT1 de angiotensina II al inhibidor de enzima de conversión, para la retirada de la dobutamina en pacientes con dependencia de soporte inotrópico que trascurre de la descompensación aguda de la insuficiencia cardiaca crónica. MÉTODOS: En un estudio caso-control (N = 24), seleccionamos a pacientes internados por descompensación de la insuficiencia cardiaca y con empleo por más de 15 días de dobutamina, o una o más intentos sin éxito de retirada; dosis optimizada de IECA; y FEVI < 0,45. Así que los pacientes recibieron adicionalmente BRA (n = 12) o no (control, n = 12). El desenlace fue el éxito en la retirada de la dobutamina, evaluado por la regresión logística, con p < 0,05. RESULTADOS: La fracción de eyección fue de 0,25, y la edad de 53 años, con dosis de dobutamina de 10,7 &#956;g/kg.min. El éxito en la retirada de dobutamina ocurrió en ocho pacientes del grupo BRA (67,7%), y en dos en el grupo control (16,7%). La "odds ratio" fue de 10,0 (intervalo de confianza de 95%:1,4 a 69,3; p = 0,02). El empeoramiento de la función renal se halló similar (grupo BRA: 42% vs grupo control: 67%, p = 0,129). CONCLUSIÓN: En este estudio piloto, la asociación BRA-IECA se relacionó al éxito en la retirada de la dobutamina, en la insuficiencia cardiaca avanzada descompensada. El empeoramiento de la función renal fue similar en ambos los grupos. Estudios adicionales son necesarios para clarificar el asunto
