非侵入性心血管功能評估－－血壓應激反應

Noninvasive Measurement of Cardiovascular Functions: Blood Pressure Reactivity to Stress

由於醫學工程發展，血液動力變化已可以利用連續性及非侵入性的生理測量儀器來加以監測。某些具有特定心理特質或生理症狀之個體在面對實驗室標準化壓力刺激下會出現有別於一般健康者之心血管系統反應。因此，個人在壓力情境下所顯現之血壓應激反應，即可做為評估個體心血管系統功能的指標，以及協助探討壓力反應與心血管疾病之間的生理機轉。本文將介紹壓力反應機轉、血壓應激反應與急性血壓調控之生理機轉、以及血壓應激反應之施測方式與測量儀器，以提供探討血壓應激反應相關研究之參考。

Advances in medical engineering have introduced novel tools to monitor changes in hemodynamics in a continuous and non-invasive manner. Blood pressure or cardiovascular reactivity to laboratory-induced mental stresses in individuals with certain traits or diseases differs from that of healthy controls. Therefore, blood pressure reactivity to stress can be used as an index of cardiovascular function. It can also be used in research to elucidate linkages between exaggerated blood pressure response and cardiovascular disease. This paper introduces the stress response and its physiologic mechanisms, blood pressure reactivity, short-term regulation of blood pressure, and blood pressure reactivity assessment methods.
