了解血压读数
What do your blood pressure numbers mean?
只有这样才能知道你有没有 高血压, also known as hypertension, is to have your blood pressure tested. Underst和ing your results is key to controlling 高血压.
Healthy 和 unhealthy blood pressure ranges
Learn what is considered normal, as recommended by the 美国心脏协会.
| 血压类别 | 收缩压毫米汞柱(上数值) | 和/或 | 舒张mm Hg(较低数值) |
|---|---|---|---|
| 正常的 | 小于120 | 和 | 少于80 |
| 升高 | 120 – 129 | 和 | 少于80 |
| HIGH BLOOD PRESSURE (HYPERTENSION) STAGE 1 | 130 – 139 | or | 80 – 89 |
| HIGH BLOOD PRESSURE (HYPERTENSION) STAGE 2 | 140或以上 | or | 90分或以上 |
| 高血压危象 (请立即咨询医生) | 大于180 | 和/或 | 大于120 |
Note: A diagnosis of 高血压 must be confirmed with a medical professional. A health care professional should also evaluate any unusually 低血压读数.

血压分类
The five blood pressure ranges as recognized by the 美国心脏协会 are:
正常的
Blood pressure numbers of less than 120/80 mm Hg (millimeters of mercury) are considered within the normal range. If your results fall into this category, stick with heart-healthy habits like following a balanced diet 和 getting regular exercise.
升高
升高 blood pressure is when readings consistently range from 120-129 systolic 和 less than 80 mm Hg diastolic. People with elevated blood pressure are likely to develop 高血压 unless steps are taken to control the condition.
高血压1期
高血压1期 is when blood pressure consistently ranges from 130 to 139 systolic or 80 to 89 mm Hg diastolic. 在高血压的这个阶段, health care professionals are likely to prescribe lifestyle changes 和 may consider adding blood pressure medication based on your risk of atherosclerotic cardiovascular disease, 或ASCVD, 比如心脏病发作或中风.
高血压2期
高血压2期 is when blood pressure consistently is 140/90 mm Hg or higher. 在高血压的这个阶段, health care professionals are likely to prescribe a combination of blood pressure medications 和 lifestyle changes.
高血压危象
This stage of 高血压 requires medical attention. If your blood pressure readings suddenly exceed 180/120 mm Hg, wait five minutes 和 then test your blood pressure again. If your readings are still unusually high, contact your health care professional immediately. 你可能正在经历 高血压危象.
If your blood pressure is higher than 180/120 mm Hg or you are experiencing signs of possible organ damage such as chest pain, 呼吸急促（气促）。, 背部疼痛, 麻木和缺点, change in vision or difficulty speaking, do not wait to see if your pressure comes down on its own. 拨打911.
Your blood pressure numbers 和 what they mean
Your blood pressure is recorded as two numbers:
- 收缩压 (the first number) – indicates how much pressure your blood is exerting against your artery walls when the heart contracts.
- 舒张压 (the second number) – indicates how much pressure your blood is exerting against your artery walls while the heart muscle is resting between contractions.
哪个数字更重要?
通常, more attention is given to systolic blood pressure (the first number) as a major risk factor for cardiovascular disease for people over 50. 对大多数人来说, systolic blood pressure rises steadily with age due to the increasing stiffness of large arteries, long-term buildup of plaque 和 an increased incidence of cardiac 和 vascular disease.
然而, either an elevated systolic or an elevated diastolic blood pressure reading may be used to make a diagnosis of 高血压.
