ABSTRACT RESUMEN En este artículo se tuvo como objetivos reverenciar a Sergei Nicolai Korotkoff con motivo del centenario del descubrimiento del método de auscultación de me-dida de la presión arterial en Rusia, en 1905; relatar los hechos que culminaron en el desarrollo de la esfignomanometría en el Brasil; historiar la valiosa contribución de la Escuela de Enfermería de la Universidad de Sao Paulo (EEUSP) en el desarrollo de la investigación en el área de la medida de la presión y analizar el producto de la línea de inves-tigación "Influencia del Ancho del brazalete en la Medida de la Presión Arterial", generada en la EEUSP a partir de 1974, eviden-ciando los estudios desarrollados en el curso de Postgrado (docto-rado) en esta institución. El artí-culo relata la consolidación de los hallazgos iniciales de los estudios que permitieron la formación de los primeros doctores en el área, que sugiere la confirma-ción de hipótesis en estudios longitudinales.

RESUMO Este artigo tem como objetivos reverenciar Sergei Nicolai Koro-tkoff por ocasião do centenário da descoberta do método auscul-tatório de medida da pressão arterial na Rússia, em 1905; relatar os fatos que culminaram no desenvolvimento da esfigmo-manometria no Brasil; historiar a valiosa contribuição da Escola de Enfermagem da Universidade de São Paulo (EEUSP) no desen-volvimento da pesquisa, na área da medida da pressão e analisar o produto da linha de pesquisa "Influência da Largura do Man-guito na Medida da Pressão Arte-rial", gerada na EEUSP a partir de 1974. O artigo relata a conso-lidação dos achados iniciais pelos estudos que permitiram a forma-ção dos primeiros doutores na área, que sugere a confirma-ção de hipóteses em estudos longitudinais.

    ABSTRACT: This study followed blood pressure in 11 subjects 5 years after slight or established hypertension had been revealed using a cuff of the correct width (appropriate to arm circumference); at that time, the use of a standard-width cuff (12 cm) had shown a blood pressure within the normal range. For the present study, blood pressure was determined indirectly under very strict conditions so that a faithful comparison between the readings with both cuffs could be achieved. An important underestimate of blood pressure was detected in thin arms when the standard width cuff was used. The present measurements showed a consistent increase in blood pressure with standard-width cuff readings, confirming the hypertension that had been identified using the correct cuff width 5 years previously. These results support our previous hypothesis that early diagnosis of hypertension can be masked by the standard-width cuff, particularly in lean persons.

    ABSTRACT: Trained nurse-specialists obtained 84 000 blood-pressure measurements in 1240 obese subjects using cuffs of the three standard adult sizes in a randomised order. The differences in readings between the three cuffs were smallest in non-obese subjects and became progressively greater with increasing arm circumference (AC) in the obese population. The regular cuff (12 X 23 cm) showed the greatest bias in relation to AC. Formulae and a table have been derived to correct the measurement error caused by cuffs of inappropriate size at various ACs. The reported high prevalence of hypertension in obese subjects may be greatly overestimated.
