O que \u00e9 a press\u00e3o arterial?<\/strong><\/h3>\n

Quando o cora\u00e7\u00e3o bate, bombeia sangue para o corpo, fornecendo-lhe nutrientes e oxig\u00e9nio. O sangue que circula faz press\u00e3o contra as paredes dos vasos sangu\u00edneos. A for\u00e7a da press\u00e3o tem o nome de press\u00e3o arterial.<\/p>\n

Quando a press\u00e3o arterial \u00e9 demasiado elevada, exerce tens\u00e3o nas paredes das art\u00e9rias, tornando-as mais suscet\u00edveis a dep\u00f3sitos de colesterol<\/a> e ao desenvolvimento de placas ateroscler\u00f3ticas (tamb\u00e9m chamadas art\u00e9rias endurecidas).<\/p>\n

Pode formar-se um co\u00e1gulo sangu\u00edneo no local da placa, que pode bloquear total ou parcialmente o fluxo sangu\u00edneo no interior da art\u00e9ria ou causar a sua rutura. Se um co\u00e1gulo bloquear um vaso sangu\u00edneo que fornece sangue ao c\u00e9rebro, d\u00e1-se um AVC. Se um co\u00e1gulo bloquear um vaso sangu\u00edneo que fornece sangue ao cora\u00e7\u00e3o, d\u00e1-se um ataque card\u00edaco. Os co\u00e1gulos bloqueados na aorta (o vaso principal do corpo) podem causar uma disse\u00e7\u00e3o potencialmente fatal.<\/p>\n

A press\u00e3o alta faz o cora\u00e7\u00e3o trabalhar mais. Isso faz com que o m\u00fasculo card\u00edaco engrosse e endure\u00e7a, o que pode levar a insufici\u00eancia card\u00edaca.<\/p>\n

Como medir a press\u00e3o arterial <\/strong><\/h3>\n

As pessoas devem saber a respetiva press\u00e3o arterial. Saber os n\u00fameros (press\u00e3o arterial, colesterol, a\u00e7\u00facar no sangue e \u00edndice de massa corporal) \u00e9 fundamental para prevenir doen\u00e7as card\u00edacas<\/a>.<\/p>\n

\"\"<\/p>\n

    \n
  1. Deve sentar-se confortavelmente numa \u00e1rea silenciosa durante aproximadamente cinco minutos antes de medir a press\u00e3o arterial.<\/li>\n
  2. O tamanho correto da bra\u00e7adeira \u00e9 importante: se for muito grande ou muito pequena, pode levar a uma leitura imprecisa.<\/li>\n
  3. A bra\u00e7adeira deve ser posicionada ao n\u00edvel do cora\u00e7\u00e3o e o bra\u00e7o deve ser apoiado sobre uma mesa ou apoio de bra\u00e7o.<\/li>\n
  4. Na sua primeira consulta ao m\u00e9dico, a press\u00e3o arterial \u00e9 registada como uma m\u00e9dia de, pelo menos, duas medi\u00e7\u00f5es.<\/li>\n<\/ol>\n

     <\/p>\n

    \"\"A leitura ser\u00e1 expressa como sist\u00f3lica sobre a press\u00e3o arterial diast\u00f3lica em mil\u00edmetros de merc\u00fario (mmHg). As press\u00f5es refletem as fases de bombeamento (sist\u00f3lica) e de repouso (diast\u00f3lica) de um batimento card\u00edaco.<\/p>\n

     <\/p>\n

    Na figura, o n\u00famero superior (120) \u00e9 a press\u00e3o arterial sist\u00f3lica e o n\u00famero inferior (70) \u00e9 a press\u00e3o arterial diast\u00f3lica.<\/p>\n

     <\/p>\n

    Press\u00e3o arterial alta<\/h3>\n

    A hipertens\u00e3o (HTA) \u00e9 diagnosticada quando a press\u00e3o arterial est\u00e1 consistentemente acima do n\u00edvel associado a um aumento do risco de doen\u00e7a cardiovascular (DCV). A PRESS\u00c3O ARTERIAL \u00e9 feita de press\u00e3o arterial sist\u00f3lica e diast\u00f3lica.<\/p>\n

    A press\u00e3o arterial normal n\u00e3o deve exceder 130 a 140 mmHg sist\u00f3lica e 80 a 90 mmHg diast\u00f3lica, dependendo da idade.<\/p><\/blockquote>\n

    A press\u00e3o arterial alta \u00e9 um assassino silencioso, porque geralmente n\u00e3o h\u00e1 sintomas. A primeira e crucial etapa \u00e9 Conhecer os seus N\u00fameros! Pe\u00e7a ao seu m\u00e9dico para medir a sua press\u00e3o arterial em diferentes ocasi\u00f5es. Tamb\u00e9m pode pedir ao seu m\u00e9dico ou farmac\u00eautico um dispositivo fi\u00e1vel para medir a press\u00e3o arterial v\u00e1rias vezes, em casa, ou continuamente durante 24 horas.<\/p>\n

    Assim que souber qual \u00e9 a sua press\u00e3o arterial, pode acordar uma estrat\u00e9gia de gest\u00e3o com o seu m\u00e9dico. Isso depender\u00e1 da sua press\u00e3o arterial e de outros fatores que influenciam o seu risco total de desenvolver DCV. Se a press\u00e3o arterial estiver elevada, o passo inicial \u00e9 melhorar o seu estilo de vida: n\u00e3o fumar<\/a>, ter uma alimenta\u00e7\u00e3o saud\u00e1vel<\/a> e fazer exerc\u00edcio f\u00edsico<\/a> regular. Perder 1 kg de gordura visceral (gordura corporal que \u00e9 armazenada dentro da cavidade abdominal \u00e0 volta de \u00f3rg\u00e3os internos importantes, como o f\u00edgado, p\u00e2ncreas e intestinos) pode diminuir a press\u00e3o arterial em quase 1 mmHg. Se a press\u00e3o arterial permanecer alta mesmo com a mudan\u00e7a comportamental, deve ser considerada uma terap\u00eautica medicamentosa. A escolha da medica\u00e7\u00e3o depender\u00e1 do seu risco individual. \u00c9 importante tomar os comprimidos conforme prescrito para evitar DCV. Lembre-se de que n\u00e3o sente a press\u00e3o arterial alta, mas o risco esta l\u00e1. \u00c9 necess\u00e1rio monitorizar a press\u00e3o arterial, ter um bom estilo de vida e tomar medicamentos para toda a vida.<\/p>\n","protected":false},"excerpt":{"rendered":"
