What Is Blood Pressure

Which Is More Important, Systolic or Diastolic Blood Pressure?

Blood pressure is the force of blood pushing against the walls of arteries as the heart pumps blood. When a health care professional measures your blood pressure, they use a blood pressure cuff around your arm that gradually tightens. The results are given in two numbers. The first number, called systolic blood pressure, is the pressure caused by your heart contracting and pushing out blood. The second number, called diastolic blood pressure, is the pressure when your heart relaxes and fills with blood.

A blood pressure reading is given as the systolic blood pressure number over the diastolic blood pressure number. Blood pressure levels are classified based on those two numbers.

  • Low blood pressure, or hypotension, is systolic blood pressure lower than 90 or diastolic blood pressure lower than 60. If you have low blood pressure, you may feel lightheaded, weak, dizzy, or even faint. It can be caused by not getting enough fluids, blood loss, some medical conditions, or medications, including those prescribed for high blood pressure.
  • Normal blood pressure for most adults is defined as a systolic pressure of less than 120 and a diastolic pressure of less than 80.
  • Elevated blood pressure is defined as a systolic pressure between 120 and 129 with a diastolic pressure of less than 80.
  • High blood pressure is defined as 130 or higher for the first number, or 80 or higher for the second number.

Staging By Jnc Based On Sbp And Dbp10 The Vast Majority Of Hypertensive Patients Over The Age Of 50 Years May Be Accurately Staged Using Sbp As The Sole Criterion Dbp = Diastolic Blood Pressure Jnc = Joint National Committee On Prevention Detection Evaluation And Treatment Of High Blood Pressure Sbp = Systolic Blood Pressure

As suggested by their age-dependent divergent patterns of onset, diastolic hypertension and ISH may be two distinct disorders with significant overlap. The conversion from diastolic hypertension to ISH in middle-age has been attributed to weakened diastolic hypertension. Although some individuals who have had untreated or poorly treated diastolic hypertension at a younger age develop ISH as they age, data from the Framingham Study suggest that only a minority of patients acquire ISH in this manner. Decreases in DBP in patients after age 60 years were observed in both normotensive and untreated hypertensive individuals, suggesting a pathway of acquisition of ISH unrelated to previous diastolic hypertension. These data imply the physiologic consequences of the aging process largely drive ISH. Aging, accelerated by accumulation of advanced glycation end products , leads to increased arterial stiffness and contributes to the development of ISH.,

When To See A Doctor

The symptoms of high blood pressure are typically silent. Many people may not find out they have high blood pressure until they visit their doctor for a routine physical. If you dont already have a primary care doctor, the Healthline FindCare tool can help you find a physician in your area.

There are many home blood pressure monitors available so that you can monitor your blood pressure at home. Some people that should consider doing this include:

  • those with a family history of high blood pressure
  • people who are overweight or obese
  • smokers
  • women who are pregnant

You should always keep a log of your readings. Its important to note that home blood pressure monitoring isnt a substitute for a doctors visit. If you find that your readings are consistently high, you should make an appointment with your doctor to discuss them.

Preventing Low Blood Pressure

To help prevent low blood pressure, drink plenty of fluids, preferably water, to prevent dehydration. Stand up slowly from a sitting position to help prevent orthostatic hypotension.

Also, notify your doctor right away if you feel a medication is causing your blood pressure to drop. There may be another medication option that will have less impact on your blood pressure numbers.

In addition, if youve been diagnosed with any medical conditions known to be linked with low blood pressure, talk to your doctor. Discuss which symptoms you should look out for and how to best monitor your condition.

Systemic Actions Of Sglt2is On Mtor Beyond The Kidney And Liver: Is The Brain A Target

Diminished nitric oxide signaling has been shown to be related to the pathological processes linked to AD and other endothelial diseases, including HF . The production of NO is reduced by endothelial NOS phosphorylation, which results in uncoupling of NO production. Excess mTOR activation has been shown to uncouple NO production via eNOS phosphorylation thereby augmenting superoxide generation . Nitric oxide is critical in maintaining endothelial function , and chronic disruption of its production could drive a path toward oxidative stress, inflammation and endothelial dysfunction . Elevated mTOR activity has also been shown in in vitro models to increase reactive oxygen species production and to blunt endothelial vasorelaxation . Rapamycin has been shown to reverse age-related, vascular endothelial dysfunction associated with a reduction in superoxide production comparable to levels seen in younger animals . Overall, this suggests the potential for SGLT2i-driven mTOR inhibition in endothelial cells in both the heart and blood-brain barrier to modulate the oxidative stress and dysfunction associated with chronic mTOR activation and to restore appropriate NO production/endothelial function.

What Should I Do If I Have High Blood Pressure

If you have been diagnosed with high blood pressure, you and your healthcare provider will talk about your target blood pressure. Your provider may suggest that you:

  • Check your own blood pressure regularly with a home blood pressure monitor. These electronic monitors are available at most pharmacies or online.
  • Work on controlling anger and managing stress.

High Blood Pressure And Older Adults

On this page:

High blood pressure, or hypertension, is a major health problem that is common in older adults. Your bodys network of blood vessels, known as the vascular system, changes with age. Arteries get stiffer, causing blood pressure to go up. This can be true even for people who have heart-healthy habits and feel just fine. High blood pressure, sometimes called “the silent killer,” often does not cause signs of illness that you can see or feel. Though it affects nearly half of all adults, many may not even be aware they have it.

If high blood pressure isn’t controlled with lifestyle changes and medication, it can lead to serious health problems, including cardiovascular disease such as heart disease and stroke, vascular dementia, eye problems, and kidney disease. The good news is that blood pressure can be controlled in most people.

How To Read Your Blood Pressure

Effect of catecholamines on systolic and diastolic blood pressure

Blood pressure readings have two numbers: a systolic pressure and a diastolic pressure, given in units of milligrams of mercury .

The higher number is the systolic blood pressure, which is the pressure generated by the heart pumping blood through the arteries. The lower number is the diastolic blood pressure, which is the pressure in the arteries while the heart is relaxing.

A normal blood pressure is less than 120 systolic over less than 80 diastolic. A systolic blood pressure in the 120s is considered elevated, even with a normal diastolic reading.

Hypertension is diagnosed with systolic reading 130 or higher, or a diastolic reading 80 or higher.

Blood Pressure Categories
> /=130 > /=90

Both systolic and diastolic measurements are important when considering your heart’s health. A high systolic reading is the most common form of high blood pressure, especially in older people, due to arteries stiffening over time.

Do I Have High Blood Pressure

Anyone can have high blood pressure. Some medical conditions, such as metabolic syndrome, kidney disease, and thyroid problems, can cause high blood pressure. Some people have a greater chance of having it because of things they can’t change. These are:

  • Age. The chance of having high blood pressure increases as you get older, especially isolated systolic hypertension.
  • Gender. Before age 55, men have a greater chance of having high blood pressure. Women are more likely to have high blood pressure after menopause.
  • Family history. High blood pressure tends to run in some families.
  • Race. African Americans are at increased risk for high blood pressure.

High blood pressure often has no signs or symptoms, but routine checks of your blood pressure will help detect increasing levels. If your blood pressure reading is high at two or more check-ups, the doctor may also ask you to measure your blood pressure at home.

There are important considerations for older adults in deciding whether to start treatment for high blood pressure if it is above 130/80, including other health conditions and overall fitness. Your doctor may work with you to find a blood pressure target that is best for your well-being and may suggest exercise, changes in your diet, and medications.

How To Properly Measure Blood Pressure

Blood pressure should be measured in a resting state, with the arm positioned roughly at the same height as the heart. To ensure reliable values, two measurements should be taken over a span of five minutes and then the average of the two readings calculated. Because blood pressure fluctuates over the course of the day, it should always be measured at the same time of day.

Stroke And Brain Problems

High blood pressure can cause the arteries that supply blood and oxygen to the brain to burst or be blocked, causing a stroke. Brain cells die during a stroke because they do not get enough oxygen. Stroke can cause serious disabilities in speech, movement, and other basic activities. A stroke can also kill you.

Having high blood pressure, especially in midlife, is linked to having poorer cognitive function and dementia later in life. Learn more about the link between high blood pressure and dementia from the National Institutes of Healths Mind Your Risks®external icon campaign.

Blood Pressure Thats Too Low

Systolic Blood Pressure

Low blood pressure is known as hypotension. In adults, a blood pressure reading of 90/60 mm Hg or below is often considered hypotension. This can be dangerous because blood pressure that is too low doesnt supply your body and heart with enough oxygenated blood.

Some potential causes of hypotension can include:

  • heart problems

Lack Of Physical Activity

A sedentary lifestyle can contribute to several health issues, including high blood pressure.

According to the AHA, physical activity can help a person lower their blood pressure. It can also improve their heart health and reduce their weight.

The AHA recommend 150 minutes a week of moderate-to-intense physical activity, such as walking briskly, running, or bicycling.

Normal Diastolic Blood Pressure

What is the normal range of diastolic pressure for adults? A normal range of diastolic blood pressure for adults is 60 mmHg to 79 mmHg.

If diastolic is less than 80 mmHg and systolic is less than 120 mmHg, a doctor will typically suggest the following:

  • Follow a heart healthy diet.
  • Engage in regular physical activity.
  • Continue avoiding unhealthy habits like excess alcohol or smoking.
  • Monitor blood pressure readings.

What Is A Blood Pressure Chart

The blood pressure chart is a way to document the readings a person has taken themselves. Because blood pressure fluctuates over the course of the day, the blood pressure chart is used to record both systolic and diastolic blood pressure, along with the date and time of the measurement. The pulse should also be recorded to provide additional information.

It allows self-monitoring of blood pressure and can help an attending doctor to better assess the values in the long term, improving the precision of the diagnosis.

What Causes Systolic Hypertension

Systolic vs. Diastolic Blood Pressure

Several psychological and physical factors can impact systolic blood pressure in an individual. However, it is important to keep in mind that blood pressure is not a static measurement, as the values for both systolic and diastolic ranges change constantly throughout the day. This is because your circulatory system is a dynamic structure that has to adjust to various stressors. As a result, your doctor will never make a diagnosis of hypertension from a single visit, but rather take blood pressure readings across multiple visits before making a definite diagnosis.

Every organ in the body contributes to your blood pressure, with the kidneys, heart, and brain playing the biggest roles in systolic blood pressure values. Heart health can directly create a significant impact on systolic blood pressure, as the force its creates may have to pump harder if you suffer from medical conditions. Having kidney failure will also lead to increases in blood pressure due to the ineffective removal of excess fluid, creating an increased burden on the heart.

Factors affecting our mental state, such as being frightened or anxious, can also affect systolic blood pressure. This is an autonomic response by the body to help deal with immediate stressors. These situations typically result in increased heart rate and blood pressure, as your body is preparing to go into action.
