The bottom line. Isolated systolic hypertension is when your systolic blood pressure is high, but your
diastolic blood pressure is normal
. It can occur naturally with age or can be caused by a variety of health conditions including anemia and diabetes.
What is the problem with high diastolic blood pressure?
A high diastolic reading (equal to or greater than 120 mmHg) is linked to a
higher risk of disease involving the large artery called the aorta that carries blood and oxygen from the heart to distant body parts
.
What factors affect diastolic blood pressure?
The factors discussed are
heart rate, arterial pressure, coronary perfusion pressure, the pericardium, and the mechanical interplay between ventricles
. The influence of heart rate, arterial pressure, and coronary perfusion pressure can be considered as minor provided they remain within their normal physiological range.
Which is more dangerous systolic or diastolic?
High systolic reading: Increases the risk of heart disease. Systolic blood pressure is linked to heart attacks, heart failure, kidney disease and overall mortality. High
diastolic
reading: Increases the risk of aortic disease.
When should I be worried about my diastolic blood pressure?
Pay attention to your diastolic number
when you have your blood pressure checked
. If your lower number is 60 or below, ask your doctor about it. Let your doctor know if you have any symptoms of hypotension or heart failure.
Should I worry if my diastolic is high?
High diastolic blood pressure symptoms
If a person gets two blood pressure readings of 180/120 mm Hg or higher, with 5 minutes between the readings, they should contact 911 or seek
emergency
medical attention.
Is 90 diastolic too high?
This is what your diastolic blood pressure number means: Normal: Lower than 80. Stage 1 hypertension: 80-89.
Stage 2 hypertension
: 90 or more.
How do you treat high diastolic blood pressure?
Diastolic hypertension, where only your diastolic blood pressure is elevated, may be treated with lifestyle changes such as
weight loss
, reducing your sodium intake or alcohol consumption, and quitting smoking.
What should my diastolic be?
For a normal reading, your blood pressure needs to show a top number (systolic pressure) that’s between 90 and less than 120 and a bottom number (diastolic pressure) that’s
between 60 and less than 80
.
Why is my diastolic high in the morning?
What causes morning hypertension? When you first wake up in the morning,
blood pressure (BP) increases due to the body’s normal circadian rhythm
. Circadian rhythm is a daily 24-hour activity cycle that affects our sleep/wake patterns.
What is a dangerous diastolic number?
The normal range of diastolic pressure should be 60 to 80 mmHg in adults. Anything above this is considered abnormal (hypertension). However, when blood pressure readings are
above 180/120 mmHg
, they are dangerous and require immediate medical attention.
What if diastolic is high and systolic is normal?
With hypertension, typically both systolic and diastolic blood pressures are elevated. However, isolated diastolic hypertension (IDH) occurs when your systolic blood pressure is normal, and only your diastolic blood pressure is high (
over 80 mm Hg
).
What happens when you have diastolic heart failure?
If you have diastolic heart failure,
your left ventricle has become stiffer than normal
. Because of that, your heart can’t relax the way it should. When it pumps, it can’t fill up with blood as it’s supposed to. Because there’s less blood in the ventricle, less blood is pumped out to your body.
Why is diastolic pressure important?
It reflects the amount of pressure inside the arteries as the heart contracts. The bottom (second) number, diastolic pressure, is
always lower
since it reflects the pressure inside the arteries during the resting phase between heartbeats. As it turns out, both systolic and diastolic blood pressure are important.
What is normal diastolic pressure?
| Blood Pressure Levels | Normal systolic: less than 120 mm Hg diastolic: less than 80 mm Hg | At Risk (prehypertension) systolic: 120–139 mm Hg diastolic: 80–89 mm Hg | High Blood Pressure (hypertension) systolic: 140 mm Hg or higher diastolic: 90 mm Hg or higher |
|---|
How long does it take to lower diastolic BP?
Many people can reduce their high blood pressure, also known as hypertension, in as
little as 3 days to 3 weeks
.
