What should diastolic pressure be

In most people, systolic blood pressure rises steadily with age due to the increasing stiffness of large arteries, long-term buildup of plaque and an increased incidence of cardiac and vascular disease.

However, either an elevated systolic or an elevated diastolic blood pressure reading may be used to make a diagnosis of high blood pressure. According to recent studies, the risk of death from ischemic heart disease and stroke doubles with every 20 mm Hg systolic or 10 mm Hg diastolic increase among people from age 40 to The abbreviation mm Hg means millimeters of mercury.

Mercury was used in the first accurate pressure gauges and is still used in medicine today as the standard unit of measurement for pressure. While both are indications of health, blood pressure and heart rate pulse are two separate measurements. Learn more about the difference between blood pressure and heart rate.

Suzanne Oparil and Dr. David Calhoun, has detailed much of the basic science showing the effect of salt at a molecular level in the blood vessels. On the inside, your blood vessels are lined with a thin monolayer of endothelial cells.

In an experimental setting, adding salt to these cells causes changes almost immediately. They become less reactive — that means they stiffen up — and lose their elasticity, which is what you actually see clinically.

Additionally, the stiffening of the vessels happens very soon after you take on a salt load during eating, which is very interesting. Lifestyle changes like diet and exercise can have immediate effects.

Your inside changes much quicker than the mirror shows you. The body is very dynamic. Within a few weeks, you can see the benefits of lifestyle change. In fact, with dietary changes in salt intake, you can see a difference in a day or two.

The first criticism was that we were looking strictly, as the name suggests, at isolated diastolic hypotension. When we looked at the patients in our study, their systolic blood pressures were all relatively normal, and we adjusted for patients with a history of hypertension.

So we actually went back and redid the analysis, completely excluding people with hypertension. And the results still remained true. In fact, the association was even stronger.

The other criticism involved something called pulse pressure. And multiple studies have shown that a widened pulse pressure is also a risk factor for cardiovascular disease. And even when we adjusted for pulse pressure, the conclusion about the low diastolic pressure still rang true.

High blood pressure, also called hypertension, is blood pressure that is higher than normal. Your blood pressure changes throughout the day based on your activities. Having blood pressure measures consistently above normal may result in a diagnosis of high blood pressure or hypertension. The higher your blood pressure levels, the more risk you have for other health problems, such as heart disease , heart attack , and stroke. Your health care team can diagnose high blood pressure and make treatment decisions by reviewing your systolic and diastolic blood pressure levels and comparing them to levels found in certain guidelines.

The guidelines used to diagnose high blood pressure may differ from health care professional to health care professional:. If you are diagnosed with high blood pressure, talk with your health care team about your blood pressure levels and how these levels affect your treatment plan.

High blood pressure usually has no warning signs or symptoms, and many people do not know they have it. Measuring your blood pressure is the only way to know whether you have high blood pressure. High blood pressure usually develops over time. It can happen because of unhealthy lifestyle choices, such as not getting enough regular physical activity.

Certain health conditions , such as diabetes and having obesity, can also increase the risk for developing high blood pressure. High blood pressure can also happen during pregnancy.
