A blood pressure of 200mmHg in the elderly is very serious. The normal range of blood pressure for adults is generally 90-140 mmHg systolic and 60-90 mmHg diastolic. 200 mmHg systolic is very high, and at this time the diagnosis is generally hypertension grade 3, i.e., very high risk group, which is a very serious diagnosis, and studies have shown that for every 10 mmHg increase in blood pressure, the risk of major cardiovascular events increases by increases by 36%. Therefore, for elderly people with 200mmHg blood pressure, they are prone to cardiovascular and cerebrovascular complications, so it is especially important to pay attention to this, and they must gradually bring their blood pressure under control in order to get the maximum benefit of lowering blood pressure, not only depending on the blood pressure value. 200mmHg blood pressure is very serious, and vascular sclerosis is usually very common and obvious in elderly people, so it is easy to cause some cardiovascular and cerebrovascular complications caused by high blood pressure at this time. This is why this time of year is prone to some of the cardiovascular and cerebrovascular complications caused by hypertension.
