FUNDAMENTO: A despeito de elevada prevalência e importância clínica da Fibrilação Atrial (FA), não existem até o momento publicações brasileiras informando o perfil clínico e a estratégia de tratamento (controle de ritmo vs. controle de frequência cardíaca) mais utilizada nesse universo de pacientes. OBJETIVO: Avaliar a estratégia de tratamento mais empregada na FA em ambulatório especializado no manejo dessa doença. Secundariamente, procurou-se descrever o perfil clínico dessa população. MÉTODOS: Estudo transversal que avaliou sequencialmente, em 167 portadores de FA, a estratégia de tratamento mais empregada, bem como o perfil clínico desses pacientes. Utilizou-se questionário padronizado para coleta de dados. A análise estatística foi realizada por meio do software SPSS® versão 13.0. RESULTADOS: Nessa população de alto risco para eventos tromboembólicos (61% com score CHADS2 > 2), em que 54% dos indivíduos apresentavam fibrilação atrial paroxística ou persistente, 96,6% utilizavam antagonistas da vitamina K ou AAS, e 76,6% faziam uso de betabloqueador (81,2% frequência x 58,8% ritmo, p < 0,05); a estratégia de controle de frequência foi a mais empregada (79,5% x 20,5%, p < 0,001). Houve uma tendência estatística a maior agrupamento de pacientes com disfunção ventricular (15,2% x 2,9%; p = 0,06), CHADS2 > 2 (60,5% x 39,5%; p = 0,07) e valvopatias (25,8% x 11,8%; p = 0,08) no segmento de controle da frequência. CONCLUSÃO: Nessa população de alto risco para eventos tromboembólicos, a estratégia de controle de frequência cardíaca foi a mais empregada.
BACKGROUND: Despite the high prevalence and clinical importance of atrial fibrillation (AF), there is no Brazilian study about the clinical profile of patients with AF and the most used treatment strategy (heart rhythm control vs. heart rate control) for them. OBJECTIVE: To assess the most used treatment strategy for AF in an outpatient clinic specialized in the management of that disease. In addition, the clinical profile of the population studied was provided. METHODS: Cross-sectional study assessing sequentially, in 167 patients with AF, the most used treatment strategy, as well as their clinical profile. A standardized form was used for data collection. The statistical analysis was performed by using the SPSS® software, version 13.0. RESULTS: In that population at high risk for thromboembolic events (61% had CHADS2 > 2), 54% of the patients had paroxysmal or persistent AF, 96.6% used vitamin K antagonists or acetylsalicylic acid, and 76.6% used beta-blocker (heart rate, 81.2% x heart rhythm, 58.8%; p < 0.05). Heart rate control was the most used treatment strategy (79.5% x 20.5%; p < 0.001). A statistical tendency towards more patients with ventricular dysfunction (15.2% x 2.9%; p = 0.06), CHADS2 > 2 (60.5% x 39.5%; p = 0.07) and heart valve diseases (25.8% x 11.8%; p = 0.08) was observed in the heart rate control group. CONCLUSION: In that population at high risk for thromboembolic events, the heart rate control strategy was the most used.

BACKGROUND: Despite the high prevalence and clinical importance of atrial fibrillation (AF), there is no Brazilian study describing the clinical profile of patients with AF and the most used treatment strategy (rhythm control vs. rate control). OBJECTIVE: Assess the most common treatment on AF in an outpatient specialized clinic for management of AF. In addition, the clinical profile of the population studied was provided. METHODS: Cross-sectional study assessing the most used strategy for atrial fibrillation control in 167 patients. The clinical profile was also described. A standardized form was used for data collection and statistical analysis was performed by SPSS 13.0 software. RESULTS: In This high risk population for thromboembolic events (61% had CHADS(2) ≥ 2), 54% of patients had paroxysmal or persistent AF, 96.6% were on vitamin K antagonists or acetylsalicylic acid, and 76.6% on beta-blocker (rate control 81,2% x rhythm control 58,8%; p < 0.05).

A statistical tendency towards more patients with ventricular dysfunction (15.2% x 2.9%; p = 0.06), CHADS(2) ≥ 2 (60.5% x 39.5%; p = 0.07) and heart valve diseases (25.8% x 11.8%; p = 0.08) was observed in the heart rate control group. CONCLUSION: In this high risk population for thromboembolic events, the rate control strategy was the most used.

Asthma patients that depend on emergency department (ED) services are generally considered to have extremely poor disease control and prognosis. It is important to identify characteristics related to poor disease control and frequent visits to the ED to apply appropriate clinical management. This study comprised a cross-sectional survey of consecutive patients with asthma exacerbation (age > or = 12 years) presenting at the adult ED of a large, tertiary care, university-affiliated hospital over a 2-month period. The frequent visitors (FV) were defined by > or = 3 visits to the ED in the preceding year, and the occasional visitors (OV) by < or = 2 visits. Eighty-six patients (61 females and 25 males) were included in the study (mean age 38 +/- 18 years). Of these patients, 51.2% were FV and 48.8% were OV. Sixty-nine percent had annual income lower than A dollar 3000 and 66.3% had < or = 8 years of the formal education. Only 18.6% had used inhaled corticosteroids, 79.1% identified the asthma attack severity, 70.9% increased or initiated inhaled beta-agonist, 20.9% increased or initiated steroid therapy, and 55.8% had an asthma action plan for attack. The number of hospital admissions in past year (OR 4.3, P = .02), use of home nebulizer (OR 3.6, P = .05) and the lack of a written asthma action plan (OR 3.3, P = .03) were independently associated with frequent visits to the ED. We conclude that a substantial proportion of the patients that visit the ED are FV. These patients are more likely to have hospital admission in the past year, to use a home nebulizer, and to lack a written asthma action plan. They should be considered the most important target for asthma education.

O aperfeiçoamento do atendimento a pacientes com asma aguda em serviço de urgência depende do reconhecimento de como realmente se trata a crise asmática na prática clínica. Objetivos: Avaliar padrão de atendimento da asma aguda no setor de adultos do departamento de emergência de um hospital universitário, utilizando como referência a conduta preconizada pelo III Consenso Brasileiro no Manejo da Asma. Pacientes e métodos: Estudo observacional conduzido durante um período de 3 meses, em 2001, no setor de adultos do departamento de emergência do Hospital de Clínicas de Porto Alegre. Os dados coletados incluíram uso de medidas objetivas para avaliar a gravidade da asma, exames solicitados, uso de terapêutica recomendada e uso de terapêutica não-recomendada. Resultados: Foram estudados um total de 108 casos de asma aguda. Destes, 4,6 por cento tiveram registro de pico de fluxo expiratório e 8,3 por cento tiveram registro de oximetria de pulso. Exames radiológicos foram realizados em 33,4 por cento dos atendimentos, hemograma em 11,1 por cento e outros exames laboratoriais em 9,3 por cento. Oxigenoterapia foi utilizada em 18,5 por cento dos pacientes, Beta-agonistas por nebulização em 100 por cento, corticosteróides em 82,4 por cento (corticosteróides via oral em apenas 8,3 por cento) e brometo de ipratrópio em 67,6 por cento. Metilxantinas foram utilizadas em 18,5 por cento dos casos (uso intravenoso em 11,1 por cento), Beta-agonistas subcutâneo em 1,9 por cento e antibióticos em 28,7 por cento. Conclusão: Este estudo identificou utilização subótima do pico de fluxo expiratório e da oximetria de pulso como medidas objetivas para avaliar a gravidade da crise asmática, e solicitação demasiada de exames radiológicos. Estes aspectos identificados serão utilizados como metas principais a serem corrigidas pela futura implantação de um protocolo assistencial para o manejo da asma aguda na sala de emergência.
