There are 2 new clinical insights of blood pressure (BP) surge. One is that the exaggerated BP surge is risk of target organ damage and future cardiovascular events, independently of the average of the 24-hr BP level (Kario K: Hypertension 56: 765-773, 2010). The cardiovascular risk is potentiated at the time period of the exaggerated BP surge. In hypertensive patiens who exhibit morning BP surge, cardiovascular events occur most frequently in the morning, while in the obstructive sleep apnea patients who exhibit sleep BP surge, cardiovascular events occur most frequently during sleep period. Another aspect is that the exaggerated BP surge is the "prehypertension" which precede hypertension (Kario K: J Hypertens 25: 1573-1575, 2007). The new BP monitoring device which detect BP surge reproducibly would clarify clinical implication of BP surge more extensively.
