高血压是危害人类健康的常见病,其定义为:在未服抗高血压药情况下,收缩压≥140毫米汞柱(18.67千帕),舒张压≥90毫米汞柱(12千帕)。大多数高血压患者在病变初期是没有明显症状的。这种状态往往要持续很长一段时间,大约半数患者是因为体检或其他疾病就诊时才发现血压升高的。这就是很多高血压患者声称自己“没有感觉”的原因。需要指出的是,高血压病的症状并不都是与血压高低成正比的。有些患者血压不高,但症状却很多;而另一些人虽然血压很高,症状却不明显。从现有治疗条件看, Hypertension is a common disease that is endangering human health and is defined as systolic blood pressure ≥140 mm Hg (18.67 kPa) and diastolic blood pressure ≥90 mm Hg (12 kPa) without antihypertensive medication. Most hypertensive patients have no obvious symptoms early in the disease. This condition often lasts for a long time, and about half of the patients are diagnosed with elevated blood pressure because of a medical examination or other medical condition. This is why many hypertensive patients claim to have “no feeling”. It should be pointed out that the symptoms of hypertension are not always proportional to the level of blood pressure. Some patients with low blood pressure, but the symptoms are many; while others, although high blood pressure, the symptoms are not obvious. From the existing treatment conditions,
