RESUMO
Hypertension is a growing concern worldwide, causing over 10 million deaths each year. The prevalence of high blood pressure (BP) in Argentina is 36.3% and 38% of these are unaware of their disease. Half of the hypertensive patients are on pharmacological treatment and only a quarter of them are controlled. The International Society of Hypertension initiated the May Measurement Month (MMM) as a global campaign to raise awareness on high BP that may also serve as a temporary solution to the lack of global screening programs worldwide. A volunteer cross-sectional survey was carried out in May 2017 across 56 health centres. Blood pressure measurement, definition of hypertension and statistical analysis followed the MMM protocol. For this awareness campaign, the Argentine Society of Hypertension coined the slogan: 'Know and control your blood pressure'. A total of 32 346 individuals aged at least 18 years were screened during MMM17. After imputation, 16 263 (50.4%) were hypertensive. Of the 12 156 receiving antihypertensive medication 5400 (44.4%) still had uncontrolled BP. MMM17, called in our country 'Know and control your blood pressure', was the largest BP screening campaign done in Argentina. Almost 6 out of 10 hypertensive patients were either not on treatment or were not controlled to the BP goal. These results suggest that appropriate screening can help to identify a significant number of people with high BP.
RESUMO
Una situación estresante produce en el individuo, como reacción, una valoración cognitiva del evento asociada con activación emocional. Esta reacción, a través de mecanismo neuroendócrinos, activa numerosos sistemas siendo uno de ellos el cardiocirculatorio. Esta respuesta ciruclatoria, puede ser valorada en laboratorio. Nuestro propósito es presentar un instrumento: DEXTERIMETRO, creado en nuestro laboratorio para producir estrés psicológico de corta duración, y valaorar su efectividad, utilizando como variable la PA (PAS y PAD). Para este fin, adminsitramos la prueba a 76 estudiantes voluntarios de 3§ año de Medicina, con edad promedio de 21 años. En cada caso registramos dos medidas de PA: una antes de la ejecución y otra al finalizar la misma. El incremento promedio de PAS fue de 11,15 mmHg, y de PAD: 8,88 mmHg. Además, se observó, en el 14% de los sujetos, una marcada reactividad vascular (incremento mayor al incremento medio más una desviación estándar). Se discute el valor del dexterímetro para detectar futuros hipertensos a partir de la valoración de reactividad de PA
