The diastolic reading, or the bottom number, is the pressure in the arteries when the heart rests between beats. This is the time when the heart fills with blood and gets oxygen. This is what your diastolic blood pressure number means: Normal: Lower than 80.

Common Reasons for High Blood Pressure in Young Adults Normal, healthy blood pressure is less than 120 millimeters of mercury (mmHg) of systolic pressure and less than 80 mmHg of diastolic pressure.

Elevated systolic or diastolic pressure is called hypertension or high blood pressure. When only the diastolic pressure is elevated, the condition is called isolated diastolic hypertension. The condition may be a normal consequence of aging or seen in some diseases, such as diabetes mellitus.

Diastolic blood pressure tends to increase up to the age of about 50 and the increase is due to the rise in arteriolar resistance. The large artery stiffening that occurs later in life contributes to a wider pulse pressure including a decreased diastolic blood pressure.

Stage 1 hypertension is a systolic pressure ranging from 130 to 139 mm Hg or a diastolic pressure ranging from 80 to 89 mm Hg.

A diastolic blood pressure (DBP) of somewhere between 60 and 90 mm Hg is good in older people. Causes of low DBP include bed rest, dehydration, loss of water, alcohol use, hormone deficiencies, allergic reactions, nutritional deficiencies and prolonged standing leading to blood pooling in the legs.

As we age, we lose the elasticity of our arteries. For some older adults, arteries may become too stiff to spring back between heartbeats, causing diastolic blood pressure to be low. Too much salt in your diet. Dietary salt can decrease elasticity of your blood vessels.

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.

Stage 1 high blood pressure is when systolic is 130 to 139 or diastolic is 80 to 89. Stage 2 high blood pressure is when systolic is 140 or higher or diastolic is 90 or higher.

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.

DOI: 10.17352/ach.000028 In various guidelines, isolated diastolic hypertension is defined as diastolic blood pressure >80 or >90mmHg in individuals with normal systolic blood pressure.

Study subjects were employee participants in an occupationally based, union-sponsored, systematic hypertension control program who began therapy between May 1973 and December 1992. 89 Hypertension was defined as an initial untreated systolic BP greater than or equal to 160 mm Hg and/or diastolic BP greater than or equal to 90 mm Hg.

Although treatment is not recommended in young people in isolated diastolic hypertension, treatment should be individualized according to the underlying cardiovascular disease in the elderly. Hypertension (HT) is one of the most common chronic diseases that increase cardiovascular morbidity and mortality [1].

Causes Kidney problems have been implicated in possible causes of elevated diastolic blood pressure. Renovascular hypertension also known as renal hypertension, in particular, is thought to be linked to IDH due to the role the kidneys play in releasing hormones that regulate blood pressure.
