High blood pressure refers to pressure above what is considered normal (140 / 90 mm Hg). When the pressure in blood vessels is excessive for long periods of time, it results in general damage to organs throughout the body.
所謂高血壓，就是血管裡的壓力高於正常（收縮壓高於 140 毫米汞柱 mmHg 或舒張壓高於 90mmHg），當血管壓力長期超過負荷，就會對全身器官造成廣泛性的傷害。
