What are the causes of diastolic blood pressure decline?

The causes of diastolic blood pressure drop include senile degenerative changes, aortic valve insufficiency, simple systolic hypertension, etc. The specific analysis is as follows:

1. Senile degenerative changes

With the increase of age, vascular elasticity decreases, resulting in reduced vascular elastic retraction ability, resulting in diastolic blood pressure drop.

2. Aortic valve insufficiency

If the patient's aortic valve insufficiency, so that systolic period, blood reflux to the left ventricle, the above phenomenon will also occur.

3. Simple systolic hypertension

If the patient is simple systolic hypertension, resulting in myocardial contraction, the impact force on the artery increases, so that blood pressure increases, but myocardial relaxation, there will be reduced vascular elasticity, diastolic blood pressure decreases.
