If your diastolic blood pressure is too low, your heart muscles won’t get enough oxygenated blood. This can lead to the weakening of your heart, a condition called diastolic heart failure.
If you have a low diastolic pressure, it means you have a low coronary artery pressure, and that means your heart is going to lack blood and oxygen. That is what we call ischemia, and that kind of chronic, low-level ischemia may weaken the heart over time and potentially lead to heart failure.
Low diastolic blood pressure, or isolated diastolic blood pressure, is when the diastolic blood pressure falls below 60 mm Hg while the systolic blood pressure remains at a healthy...
These numbers indicate the pressure on blood vessels when your heart beats (systolic blood pressure) and rests (diastolic blood pressure). Systolic BP is always the first or top number. Blood pressure below 120/80 mmHg is generally regarded as being in a healthy zone.
If you have symptoms of extreme low blood pressure or shock, call 911 or your local emergency number. Most healthcare professionals consider blood pressure to be too low only if it causes symptoms. Minor dizzy or lightheaded feelings from time to time can be caused by many things.
A low blood pressure reading is usually good. Some people with very low blood pressure have a condition called hypotension. This occurs when blood pressure is less than 90/60 mm Hg. Low blood pressure is usually not harmful unless there are other symptoms that concern a health care professional.
Diastolic pressure is the pressure during the resting phase between heartbeats, as coronary vessels supply oxygen to the heart muscle. It’s important to keep the number low, but not too low. The bottom (diastolic) number in blood pressure plays an essential role in heart health.
