A differential pressure of about 100 mmHg may indicate a risk of cardiovascular disease and insufficient blood supply to the organs. The normal differential pressure value is 30-80mmHg, when the patient’s differential pressure is 100mmHg, it suggests the existence of systolic pressure is too high as well as diastolic pressure is too low. If the systolic pressure is too high, it means that the patient has already reached the degree of moderate to severe hypertension, and at this time it is very easy to have cerebral hemorrhage, hemorrhagic stroke and other cardiovascular and cerebrovascular diseases. If the diastolic blood pressure is too low, then the patient may have aortic arteriosclerosis, aortic valve closure insufficiency and other conditions, which leads to an increase in the pressure difference, and then the patient may be due to the diastolic blood pressure is too low and lead to insufficient blood supply to the organs, causing panic, palpitations and other discomforts.
