Abstract

Background: Blood pressure variability (BPV) is of prognostic value for fatal and non-fatal cardiovascular outcomes.

Objective: This study aimed to evaluate the association between within-visit BPV and cardiovascular risk among participants of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).

Methods: The present cross-sectional study was carried out using baseline data (2008-2010) of 14,357 ELSA-Brasil participants with no prior history of cardiovascular disease. Within-visit BPV was quantified by the coefficient of variation of three standardized systolic blood pressure (SBP) measurements using an oscillometer. Anthropometric measurements and laboratory tests were also performed. Cardiovascular risk was assessed using the atherosclerotic cardiovascular disease risk estimator (ASCVD) and multivariate logistic regression analysis was employed with a significance level of 5%.

Results: Significantly higher cardiovascular risk was determined by increased BPV for both sexes. A significantly higher prevalence of high risk was found in men than women across all quartiles, with the highest difference observed in the fourth quartile of variability (48.3% vs. 17.1%). Comparisons among quartiles in each sex revealed a significantly higher cardiovascular risk for men in the third (OR=1.20; 95%CI: 1.02 - 1.40) and fourth quartiles (OR=1.46; 95%CI: 1.25 -1.71), and for women in the fourth quartile (OR=1.27; 95%CI: 1.03 - 1.57).

Conclusion: Analysis of baseline data of the ELSA-Brasil participants revealed that blood pressure variability was associated with increased cardiovascular risk, especially in men.

Fundamento: A variabilidade da pressão arterial (VPA) tem valor prognóstico para desfechos cardiovasculares fatais e não fatais.

Objetivos: Este estudo teve como objetivo avaliar a associação entre a VPA em uma única visita e o risco cardiovascular em participantes do Estudo Longitudinal de Saúde do Adulto (ELSA-Brasil).

Métodos: O presente estudo transversal foi conduzido com dados basais (2008-2010) de 14.357 participantes do ELSA-Brasil, sem história de doença cardiovascular. A VPA foi quantificada pelo coeficiente de variação de três medidas padronizadas da pressão arterial sistólica (PAS) realizadas com um oscilômetro. Medidas antropométricas e exames laboratoriais também foram realizados. O risco cardiovascular foi avaliado pelo estimador de risco de doença cardiovascular aterosclerótica (ASCVD), e se empregou a análise de regressão logística multivariada com nível de significância de 5%.

Resultados: Um risco cardiovascular significativamente maior foi determinado por uma VPA elevada para ambos os sexos. Uma prevalência significativamente maior de alto risco foi observada mais em homens que em mulheres em todos os quartis, com a maior diferença observada no quarto quartil de variabilidade (48,3% vs. 17,1%). Comparações entre quartis por sexo revelaram um risco significativamente mais alto para homens no terceiro (OR=1,20; IC95%: 1,02 - 1,40) e no quarto quartis OR=1,46; IC95%: 1,25 -1,71), e para mulheres no quarto quartil (OR=1,27; IC95%: 1,03 - 1,57).

Conclusão: Análises de dados basais de participantes do ELSA-Brasil revelaram que a variabilidade da pressão arterial se associou com risco cardiovascular aumentado, especialmente nos homens.
