Blood Pressure
血压
When your heart beats, it pumps blood around your body. As the blood moves, it pushes against the sides of the blood vessels. The strength of this pushing is your blood pressure.
随着心脏跳动，它将血液泵送到全身。血液在血管内流动时，将推压血管壁。血液对血管壁产生的压力是血压。
As your heart pumps, the flow of blood in your arteries - and your blood pressure - rises and falls in a regular wave pattern.
随着心脏泵血，动脉血管内的血流和血压以有规律的波动模式上升和下降。
Blood pressure is shown as two numbers. The top number, or systolic pressure, is the pressure when your heart beats. The bottom number, or diastolic pressure, is the pressure when your heart relaxes.
血压用两个数字表示。上面的数字，或收缩压，是心脏跳动时产生的压力。下面的数字，或舒张压，是心脏舒张时产生的压力。
Healthy blood vessels can stretch to allow for these changes in pressure. Damaged blood vessels are less stretchy, which increases blood pressure. Constant high blood pressure puts extra strain on your heart and blood vessels.
健康的血管有弹性，可以适应这些压力变化。但是受损的血管弹性较小，会导致血压升高。血压持续升高将对心脏和血管造成进一步的损害。
Over time, this increases your risk of a heart attack or stroke. It can also cause problems for your eyes and kidneys.
随着时间的推移，这将导致心脏病发作或卒中风险增加，眼睛和肾脏也会出现问题。
High blood pressure speeds up the process of atherosclerosis, where fatty streaks form inside the arteries.
高血压会加速动脉粥样硬化（动脉内形成脂质条纹）的进程。
If one of these cracks, it can cause a blood clot in your arteries. This is what causes a heart attack or stroke. It's never too late to make changes to protect your heart.
如果其中一条脂质条纹突然断裂，动脉血管内将形成血栓。这就是心脏病发作或卒中发生的原因。及时做出改变对于保护心脏至关重要。
Think about your future: being there for your family, your plans and dreams. Could your blood pressure affect this?
畅想未来骨肉团圆、抱负得成，梦想实现的美好画面，而血压会导致这一切化为泡影？
There are steps you can take today to lower your risk. If you smoke, stop smoking. Make heart healthy eating and drinking choices, Move more, Lose weight, Talk to your doctor about medications.
我们可以采取一些措施来降低风险：吸烟者，请戒烟！选择有益心脏健康的饮食、多运动、减肥，向医生咨询最适合自己的药物。
