    <p>A anticoagula&#231;&#227;o &#233; uma abordagem terap&#234;utica padr&#227;o para pacientes com fibrila&#231;&#227;o atrial (FA), exigindo uma an&#225;lise cuidadosa do equil&#237;brio entre a efic&#225;cia antitromb&#243;tica e o risco de complica&#231;&#245;es hemorr&#225;gicas. Os autores examinaram a taxa de prescri&#231;&#227;o de anticoagulantes entre pacientes admitidos no pronto-socorro com FA sintom&#225;tica, revelando uma maior preval&#234;ncia de n&#227;o prescri&#231;&#227;o em mulheres em compara&#231;&#227;o com homens.<sup><xref ref-type="bibr" rid="B1">1</xref></sup> Essa observa&#231;&#227;o levanta diversas preocupa&#231;&#245;es importantes.</p>
    <p>O escore mediano CHA<sub>2</sub>DS<sub>2</sub>-VASc foi relatado como 2 em homens e 4 em mulheres,<sup><xref ref-type="bibr" rid="B1">1</xref></sup> um valor relativamente modesto. Em contraste, candidatos &#224; oclus&#227;o do ap&#234;ndice atrial esquerdo, tipicamente necess&#225;ria devido a um risco elevado de sangramento que contraindica a anticoagula&#231;&#227;o a longo prazo, geralmente apresentam maior escore CHA<sub>2</sub>DS<sub>2</sub>-VASc.<sup><xref ref-type="bibr" rid="B5">2</xref></sup> Al&#233;m disso, estudos recentes sugerem que pacientes com FA assintom&#225;tica enfrentam maiores riscos de eventos adversos em compara&#231;&#227;o &#224;queles com FA sintom&#225;tica.<sup><xref ref-type="bibr" rid="B3">3</xref></sup> A coorte estudada aqui pode n&#227;o ser totalmente representativa das popula&#231;&#245;es contempor&#226;neas de FA.</p>
    <p>O mecanismo subjacente que explica a maior idade de in&#237;cio da FA em mulheres em compara&#231;&#227;o aos homens permanece obscuro e pode envolver fatores de confus&#227;o n&#227;o abordados.<sup><xref ref-type="bibr" rid="B1">1</xref></sup> Por exemplo, o abuso de &#225;lcool, um fator de risco conhecido para FA recorrente ap&#243;s abla&#231;&#227;o por cateter, &#233; supostamente mais prevalente entre os homens,<sup><xref ref-type="bibr" rid="B4">4</xref></sup> o que pode ser parcialmente respons&#225;vel pelas diferen&#231;as observadas.</p>
    <p>Al&#233;m disso, os riscos de acidente vascular cerebral e sangramento s&#227;o significativamente influenciados por interven&#231;&#245;es como abla&#231;&#227;o por cateter e fechamento do ap&#234;ndice atrial esquerdo. &#201; fundamental esclarecer quantos pacientes no estudo foram submetidos a esses procedimentos e se ocorreram eventos adversos ap&#243;s a interven&#231;&#227;o.</p>

      <p>Os autores apreciam o interesse em nosso artigo e os pontos importantes levantados. Em rela&#231;&#227;o &#224; &#8220;representatividade das popula&#231;&#245;es contempor&#226;neas com FA&#8221;, concordamos que nossa amostra n&#227;o &#233; totalmente representativa das popula&#231;&#245;es com FA, conforme afirmamos nas limita&#231;&#245;es do estudo. Embora tenhamos realizado um estudo multic&#234;ntrico com uma amostra muito grande da maior rede hospitalar privada da Am&#233;rica Latina, n&#227;o inclu&#237;mos hospitais p&#250;blicos. Al&#233;m disso, os achados, como os valores de CHA<sub>2</sub>DS<sub>2</sub>VASc (mediana de 2 para homens e 4 para mulheres), foram semelhantes aos do Registro Cardiovascular Brasileiro de Fibrila&#231;&#227;o Atrial (Estudo RECALL), cuja pontua&#231;&#227;o m&#233;dia foi de 3,2.<sup><xref ref-type="bibr" rid="B5">1</xref></sup></p>
      <p>A diferen&#231;a de idade entre homens e mulheres na popula&#231;&#227;o estudada, como j&#225; apontado em outros estudos,<sup><xref ref-type="bibr" rid="B6">2</xref></sup> pode estar associada a diferentes mecanismos fisiopatol&#243;gicos. Como mencionado, o consumo de &#225;lcool, um conhecido fator de risco para fibrila&#231;&#227;o atrial, pode ser um fator importante associado ao aumento da incid&#234;ncia de taquiarritmias em homens jovens.<sup><xref ref-type="bibr" rid="B7">3</xref></sup></p>
      <p>De fato, a abla&#231;&#227;o e o fechamento do ap&#234;ndice atrial esquerdo s&#227;o interven&#231;&#245;es que podem reduzir o risco de acidente vascular cerebral e sangramento a longo prazo. No entanto, nosso estudo n&#227;o se concentrou na preval&#234;ncia de complica&#231;&#245;es cl&#237;nicas associadas &#224; fibrila&#231;&#227;o atrial, mas sim na adequa&#231;&#227;o da indica&#231;&#227;o da terapia anticoagulante, revelando resultados paradoxais em rela&#231;&#227;o ao g&#234;nero, com mulheres apresentando maior risco, por&#233;m menor indica&#231;&#227;o de profilaxia. Al&#233;m disso, como n&#227;o h&#225; consenso sobre a descontinua&#231;&#227;o da terapia antitromb&#243;tica ap&#243;s a abla&#231;&#227;o, esses aspectos n&#227;o foram inclu&#237;dos na an&#225;lise, sem afetar as conclus&#245;es do estudo.</p>

      <p>Anticoagulation is a standard therapeutic approach for patients with atrial fibrillation (AF), requiring careful consideration of the balance between antithrombotic efficacy and the risk of hemorrhagic complications. The authors examined the rate of anticoagulant prescriptions among patients admitted to the emergency department with symptomatic AF, revealing a higher prevalence of non-prescription in women compared to men.<sup><xref ref-type="bibr" rid="B1">1</xref></sup> This observation raises several important concerns.</p>
      <p>The median CHA<sub>2</sub>DS<sub>2</sub>-VASc score was reported as 2 in men and 4 in women,<sup><xref ref-type="bibr" rid="B1">1</xref></sup>a relatively modest value. In contrast, candidates for left atrial appendage closure, typically necessitated by an elevated bleeding risk that contraindicates long-term anticoagulation, generally present with higher CHA<sub>2</sub>DS<sub>2</sub>-VASc scores.<sup><xref ref-type="bibr" rid="B2">2</xref></sup> Furthermore, recent studies suggest that patients with asymptomatic AF face higher risks of adverse events compared to those with symptomatic AF.<sup><xref ref-type="bibr" rid="B3">3</xref></sup> The cohort studied here may not be fully representative of contemporary AF populations.</p>
      <p>The underlying mechanism explaining the higher age of AF onset in women compared to men remains unclear and may involve unaddressed confounding factors.<sup><xref ref-type="bibr" rid="B1">1</xref></sup> For example, alcohol abuse, a known risk factor for recurrent AF following catheter ablation, is reportedly more prevalent among men,<sup><xref ref-type="bibr" rid="B4">4</xref></sup> which could partly account for the observed differences.</p>
      <p>Additionally, the risks of both stroke and bleeding are significantly influenced by interventions such as catheter ablation and left atrial appendage closure. It is imperative to clarify how many patients in the study underwent these procedures and whether adverse events occurred post-intervention.</p>

        <p>The authors appreciate the interest in our paper and the important points raised. Regarding the &#8220;<italic>representativeness of contemporary AF populations</italic>&#8221;, we agree that our sample is not fully representative of AF populations, as we stated in the limitations of the study. Even though we performed a multicenter study with a very large sample from the largest private hospital network in Latin America, we did not include public hospitals. Moreover, the findings, such as the CHA<sub>2</sub>DS<sub>2</sub>VASc values (median of 2 for men and 4 for women), were similar to those of the Brazilian Cardiovascular Registry of Atrial Fibrillation (RECALL Study), whose average score was 3.2.<sup><xref ref-type="bibr" rid="B5">1</xref></sup></p>
        <p>The difference in age between men and women in the study population, as already pointed out in other studies,<sup><xref ref-type="bibr" rid="B6">2</xref></sup> may be associated with different pathophysiological mechanisms. As mentioned, alcohol use, a known risk factor for atrial fibrillation, may be an important factor associated with the increased incidence of tachyarrhythmia in young men.<sup><xref ref-type="bibr" rid="B7">3</xref></sup></p>
        <p>Indeed, ablation and left atrial appendage closure are interventions that can reduce the long-term risk of stroke and bleeding. However, our study did not focus on the prevalence of clinical complications associated with atrial fibrillation but rather on the appropriateness of anticoagulant therapy indication, revealing paradoxical results related to gender, with women exhibiting a higher risk yet lower prophylaxis indication. Furthermore, since there is no consensus on discontinuing antithrombotic therapy after ablation, these aspects were not included in the analysis without affecting the study&#8217;s conclusions.</p>
