Doctor insights on: What is considered too low for diastolic pressure
Depends: "too low" implies that it is a problem. 70 is lower than average but would not raise an eyebrow. 50-60 is unusual and would lead me to think, why? If you feel well it is probably not a problem. But if the diastolic pressure is on the low side, I would consider things that might cause that even if the patient is well. Leaking of the aortic valve for instance can cause a low diastolic pressure. ...Read moreSee 1 more doctor answer
Probably not: A low diastolic blood pressure with a normal diastolic blood pressure often is of no significance. In some people, their blood pressure sounds can be heard all the way down to 0 when nothing is wrong. A large difference between systolic and diastolic pressures (wide pulse pressure) may indicate aortic regurgitation, however. Check with your doctor. ...Read more
In the elderly:
Hello livk --
diastolic pressure is commonly lower as we get older -- partly due to the increased stiffness of the vessel and low volume reserve.
However, please note that diastolic pressure is rarely accurate using the automated home BP machine -. ...Read more
60 mmHg: The normal diastolic pressure for adults is 80mmhg. Can be considered acceptable from 70 to 85 mmhg. Higher than that is prehypertension. Lowr than 70 mmhg is common normal finding in patients older than 70 years old. Diastolic blood pressure lower than 60 mmhg in adults younger than 65yo raises the ssupicion of valvular problems. ...Read moreSee 1 more doctor answer
Nope: Some people who walk around and feel well have diastolic bps of zero. (at least as estimated by a BP cuff which is an indirect measurement). My only caveat: get an echo and be sure you don't have aortic regurgitation which can be severe, cause no symptoms for years, and be hard to detect with a stethoscope. ...Read more
Several reasons: Most high blood pressure is idiopathic (no reason, you just have it) whether it is systolic or diastolic. It runs in families so if your parents have it, you are more likely to get it. There are occasion cases secondary to specific causes such as adrenal tumors, kidney problems, or narrowing of the aorta (called coarctation) and that is called secondary hypertension. ...Read moreSee 1 more doctor answer
Vascular tone: Both systolic and diastolic pressures are significantly impacted by the level of vascular tone or "resistance" or restriction to a given rate of blood flow. Although we have excellent medication options for managing vascular resistance, I have found that good cardiovascular conditioning seems to positively impact the diastolic blood pressure by enhancing "run off" in the peripheral vascular bed. ...Read moreSee 1 more doctor answer
Why would you?: A low diastolic blood pressure could be due to leaking of the aortic valve or other problems so finding the cause is important. If you feel well, a low pressure, diastolic or systolic, may not be a bad thing. People with relatively low blood pressure live longer. And, how low are you talking about? ...Read moreSee 2 more doctor answers
Artery Stiffness: The diastolic blood pressure or the "bottom number" when the blood pressure is taken is when the pressure at which the heart beat is no longer heard by the stethescope. It is related to the stiffness of the arterial tree in the body. The stiffer the artery the higher the diastolic pressure. ...Read moreSee 2 more doctor answers
Whenever you want: Diastolic blood pressure refers to the pressure in the arteries during the period of heart's relaxation, i.e. Once it finished ejecting blood during contraction. For every single heart beat, there is the period of contraction ("systolic blood pressure") and the relaxation ("diastolic"). In any single cardiac cycle, each of these arterial pressures can be measured. ...Read moreSee 1 more doctor answer
DPTI: It is a measure of coronary blood supply. Multiply the coronary perfusion pressure times the diastolic tmie. Cpp =diastollic blood pressure minus the left vetricular end diastolic pressure. Diastolic time is 60sec/heart rate-0.2seconds. The 0.2 is systolic time (fixed at 0.2s). Coronary flow occurs during diastole and relates to the pressure and how long diastole lasts. Now ask me what the evr is. ...Read moreSee 1 more doctor answer
Pressure in arteries: The pressure in the arteries when the heart contracts is the systolic blood pressure and when it relaxes the pressure is the diastolic pressure. It could be measured directly by putting a needle into an artery or indirectly with a blood pressure cuff. ...Read moreSee 1 more doctor answer
