    <p>A homeostase da press&#227;o arterial (PA) &#233; um elemento crucial na prote&#231;&#227;o de eventos cardiovasculares. Muitas diretrizes nacionais e internacionais <sup><xref ref-type="bibr" rid="B1">1</xref> - <xref ref-type="bibr" rid="B4">4</xref></sup> propuseram valores-alvo para a press&#227;o arterial, e essas recomenda&#231;&#245;es consideram metas ligeiramente diferentes de acordo com os est&#225;gios da hipertens&#227;o, estratifica&#231;&#227;o de risco e presen&#231;a de doen&#231;as renais ou cardiovasculares e les&#227;o de &#243;rg&#227;o-alvo. No entanto, esses valores s&#227;o baseados em medidas de consult&#243;rio, monitoriza&#231;&#227;o ambulatorial da press&#227;o arterial (MAPA) e monitoriza&#231;&#227;o domiciliar da press&#227;o arterial (MDRA), n&#227;o levando em conta a variabilidade da press&#227;o arterial (VPA). A variabilidade interindividual da PA &#233; um fator de risco independente para doen&#231;as cardiovasculares independentemente da PA m&#233;dia. <sup><xref ref-type="bibr" rid="B5">5</xref> - <xref ref-type="bibr" rid="B7">7</xref></sup> As flutua&#231;&#245;es nas medidas fisiol&#243;gicas da press&#227;o arterial n&#227;o ocorrem aleatoriamente e podem contribuir ou ser preditores de desfechos cardiovasculares.</p>
    <p>A maioria dos estudos avaliou a VPA em curto (24h), m&#233;dio (&gt;2 dias) ou longo prazo (semanal, mensal ou anual). <sup><xref ref-type="bibr" rid="B8">8</xref> , <xref ref-type="bibr" rid="B9">9</xref></sup> A VPA de curto prazo pode estar associada ao aumento do risco cardiovascular. <sup><xref ref-type="bibr" rid="B10">10</xref> , <xref ref-type="bibr" rid="B11">11</xref></sup></p>
    <p>No estudo de Zarife et al., <sup><xref ref-type="bibr" rid="B12">12</xref></sup> os autores utilizaram dados basais de 14.357 participantes do ELSA-Brasil sem hist&#243;ria pr&#233;via de doen&#231;a cardiovascular.</p>
    <p>A VPA foi quantificada em uma &#250;nica visita na linha de base pelo coeficiente de varia&#231;&#227;o de tr&#234;s medidas padronizadas de press&#227;o arterial sist&#243;lica usando um oscil&#244;metro validado (Omron HEM 705CPINT) e correlacionado com o risco de DCVA. A VPA foi dividida em quartis, e o quartil mais alto foi associado a um risco cardiovascular significativamente maior em homens e mulheres. O sexo masculino apresentou maior risco cardiovascular do que o feminino em todos os quartis, sendo a maior diferen&#231;a observada no quarto quartil do VPA. Al&#233;m disso, a compara&#231;&#227;o dos quartis por sexo mostrou risco significativamente maior para os homens no terceiro e quarto quartis e no quarto quartil para as mulheres. A VPA tamb&#233;m foi associada a maior velocidade de onda de pulso, menor taxa de filtra&#231;&#227;o glomerular e hipercolesterolemia. Nenhum estudo relatou avalia&#231;&#227;o de risco cardiovascular e VPA em uma &#250;nica visita. Os resultados do ELSA-Brasil, nesta grande coorte prospectiva, sugerem que este pode ser um marcador de risco de doen&#231;a cardiovascular e ajudar a identificar pacientes que necessitam de acompanhamento mais pr&#243;ximo ou terapia mais intensiva. Vale ressaltar que a maioria dos participantes do ELSA-Brasil era de indiv&#237;duos normotensos (64%), refor&#231;ando o conceito de que a press&#227;o arterial &#233; uma medida cont&#237;nua de risco e que a VPA pode ser importante n&#227;o apenas para os hipertensos, mas tamb&#233;m pode ser avaliada em indiv&#237;duos com medidas normais de press&#227;o arterial. Outros passos devem ser a avalia&#231;&#227;o da VPB em visita &#250;nica e dos desfechos cardiovasculares no ELSA-Brasil. no ELSA-Brasil.</p>

    <body>
      <p>Blood pressure (BP) homeostasis is a crucial element in the protection of cardiovascular events. Many national and international guidelines<sup><xref ref-type="bibr" rid="B1">1</xref> - <xref ref-type="bibr" rid="B4">4</xref></sup> have proposed target values for blood pressure, and these recommendations consider slightly different goals according to hypertension stages, risk stratification and presence of renal or cardiovascular diseases, and target organ lesion. However, these values are based on office measures, ambulatory blood pressure monitoring (ABPM) and home blood pressure monitoring (HBPM), not accounting for blood pressure variability (BPV). BP intraindividual variability is an independent risk factor for cardiovascular diseases regardless of mean BP.<sup><xref ref-type="bibr" rid="B5">5</xref> - <xref ref-type="bibr" rid="B7">7</xref></sup> Fluctuations in physiological measures of blood pressure do not occur randomly and can contribute or be predictors of cardiovascular outcomes.</p>
      <p>Most studies evaluated BPV on short (24h), medium (&gt;2 days) or long-term (weekly, monthly, or annually).<sup><xref ref-type="bibr" rid="B8">8</xref> , <xref ref-type="bibr" rid="B9">9</xref></sup> Short-term BPV can be associated with increased cardiovascular risk.<sup><xref ref-type="bibr" rid="B10">10</xref> , <xref ref-type="bibr" rid="B11">11</xref></sup></p>
      <p>In the study by Zarife et al.,<sup><xref ref-type="bibr" rid="B12">12</xref></sup> the authors used baseline data from 14,357 participants of ELSA-Brasil without prior history of cardiovascular disease.</p>
      <p>BPV was quantified in a single visit at baseline by the coefficient of variation of three standardized systolic blood pressure measurements using a validated oscilometer (Omron HEM 705CPINT) and correlated with ASCVD risk. BPV was divided into quartiles, and the highest quartile was associated with a significantly higher cardiovascular risk in both men and women. Males had a higher cardiovascular risk than females in all quartiles, with the greatest difference observed in the fourth BPV quartile. In addition, comparing quartiles by sex showed a significantly higher risk for men in the third and fourth quartiles and the fourth quartile for women. BPV was also associated with higher pulse-wave velocity, lower glomerular filtration rate, and hypercholesterolemia. No studies have reported cardiovascular risk assessment and BPV in a single visit. The results from ELSA-Brasil, in this large prospective cohort suggest that this can be a marker of cardiovascular disease risk and help identify patients needing closer monitoring or more intensive therapy. It is worthy to note that the majority of participants of ELSA-Brasil were normotensive individuals (64%), reinforcing the concept that blood pressure is a continuous measure of risk and that BPV can be important not only for those with hypertension but can be assessed in subjects with normal blood pressure measures. Further steps should be assessing single visit BPV and cardiovascular outcomes in ELSA-Brasil.</p>
