Q: A high diastolic can be caused by stiffening of the arteries, through age, or through coronary artery disease As people become older, the diastolic pressure will begin to decrease and the systolic blood pressure begins to rise and becomes more important.
...There is a differentiation with diastolic and age. For the younger people, the diastolic blood pressure is an important metric. The diastolic blood pressure has been and remains, especially for younger people, an important hypertension number. Your comment..."maintaining a high diastolic can cause artery disease and gives a much higher risk of heart attack, stroke..." refers to younger individuals (recheck your source)... As people become older, the diastolic pressure will begin to decrease and the systolic blood pressure begins to rise and becomes more important.
You can visit the archieves for information on pulse pressure. A wide pulse pressure, difference between diastolic and systolic metric greater then 60, is a very good indication of arteriosclerosis visited on an aging individual...high systole, lower diastole.
Explanation: Arteriosclerosis is the hardening of the arteries and a rigid artery wall increases the resistence the heart pumps against and increase systolic pressure...also a narrow lumen from negative remodeling of the vessel will also increase systolic pressure. Negative remodeling is a condition in which the vessel area decreases in size, often as a result of a STRUCTURAL change in the coronary vessel wall...plaque between the vessel 3 layers can cause negative remodeling or positive remodeling (positve relates to the outer layer of the vessel.
A high diastolic and low systolic would give a low pulse pressure and it would seem the faster heart rate is an attempt at getting blood flow running normal. A high diastolic can be caused by stiffening of the arteries, through age, or through coronary artery disease. A layer of plaque would reduce the lumen size and increase pressure even when the artery/heart is relaxed.
It sounds like you should have a check up with your Doctor because maintaining a high diastolic can cause artery disease and gives a much higher risk of heart attack, stroke.
A high heart rate can affect blood pressure readings and produce inaccurate information. You should consult with your doctor regarding fast heart rate....greater than 100 heartbeats/minute. Also, a fast heart rate over a period of time can over stress the heart's functionality.
The diastolic pressure is the measurement of force as the heart relaxes to allow the blood to flow into the heart. If the muscles of the heart chambers are more rigid than normal, the condition increases the pressure, etc.
If you are on medication, that could be cause of the blood pressure, however, your heart rate should be below 100 at rest and if necessary treat.
