What does diastolic mean?

Diastolic drugs are part of blood pressure, mainly indicating that in the beating of the heart, the heart has two functions of contraction and relaxation. When relaxing, the blood volume in the blood vessels, and then a value generated by the pressure on the blood vessels. Generally, normal diastolic blood pressure is between 60 and 90. If it is elevated, it may be that there is some risk of hypertension and further diagnosis is needed. If the diastolic blood pressure is higher than the normal value for many times, it may be necessary to take antihypertensive drugs for symptomatic treatment. And if there is hypertension, it may be necessary to insist on taking antihypertensive drugs. Because high blood pressure is easy to cause cardiovascular and cerebrovascular diseases, as well as arteriosclerosis or kidney function damage.
