What’s The Difference Between Blood Pressure And Pulse
While your blood pressure is the force of your blood moving through your blood vessels, your heart rate is the number of times your heart beats per minute.
- They are two separate measurements and indicators of health.
- For people with high blood pressure , theres no substitute for measuring blood pressure.
Talk About Your Treatment
If youre told you have stage 1 hypertension, lifestyle changes like losing weight eating a healthy, low-salt diet and exercising regularly may be enough, McLean says. Theyre also appropriate if your blood pressure is considered elevated.
But theres no one-size-fits-all approach, Laffin says. And drug therapy is associated with a reduced risk of cardiovascular disease only for people with a systolic number of 140 and higher who havent had a previous cardiovascular event, according to a 2018 review of 74 studies in JAMA Internal Medicine.
Its important to talk with your doctor about your age, overall risk for heart disease, other health issues youre managing, and the possibility of side effects to determine the best target for you and how to get there, Laffin says.
Your doctor can also calculate your 10-year risk for a heart attack or stroke, which may inform your decision.
If youre starting medication, your doctor might consider a thiazide diuretic such as chlorothiazide or hydrochlorothiazide , says Harlan Krumholz, M.D., a cardiologist at Yale University. These appear to be safer and more effective at reducing heart attack, heart failure, and stroke risks than drugs called ACE inhibitors, according to a 2019 study he co-authored.
How Is High Blood Pressure Diagnosed
To figure out your blood pressure rate, your health care provider takes blood pressure readings at different times. You need more than 1 reading because blood pressure changes depending on what you are doing and varies during the day. For example, your blood pressure can increase when you are nervous or in a hurry.
If your blood pressure is high while with your health care provider but normal otherwise, you may just be nervous. This effect is common. Even people already being treated for high blood pressure go through this.
What matters is what happens to your blood pressure outside your health care providers office. If you have high blood pressure, you should use a home blood pressure monitor. Ask your health care provider how to use the monitor correctly.

Whats A Normal Reading
For a normal reading, your blood pressure needs to show a top number thats between 90 and less than 120 and a bottom number thats between 60 and less than 80. The American Heart Association considers blood pressure to be within the normal range when both your systolic and diastolic numbers are in these ranges.
Blood pressure readings are expressed in millimeters of mercury. This unit is abbreviated as mm Hg. A normal reading would be any blood pressure below 120/80 mm Hg and above 90/60 mm Hg in an adult.
If youre in the normal range, no medical intervention is needed. However, you should maintain a healthy lifestyle and healthy weight to help prevent hypertension from developing. Regular exercise and healthy eating can also help. You may need to be even more mindful of your lifestyle if hypertension runs in your family.
Heart Rate And Exercise
In discussions about high blood pressure, you will often see heart rate mentioned in relation to exercise. Your target heart rate is based on age and can help you monitor the intensity of your exercise.
- If you measure your heart rate before, during and after physical activity, youll notice it will increase over the course of the exercise.
- The greater the intensity of the exercise, the more your heart rate will increase.
- When you stop exercising, your heart rate does not immediately return to your normal heart rate.
- The more fit you are, the sooner your heart rate will return to normal.

Salt Intake And High Blood Pressure
Reducing the amount of salt you eat can also help to manage or even avoid high blood pressure. To help reduce your salt intake:
- Ensure your diet consists of wholefoods including vegetables, fruits, wholegrains, lean meat and poultry, fish and seafood, legumes, unsalted nuts and seeds.
- Avoid packaged and processed foods that are high in salt. You cant see the salt in these foods, so you dont know how much salt you are having. Get into the habit of checking food labels.
- Choose low-salt food where possible. If you cant find low-salt products, those with moderate amounts of salt are ok too. Another simple alternative is to look for labels with low salt, salt reduced or no added salt.
- Avoid adding salt to cooking or at the table flavour meals with herbs and spices instead.
High Blood Pressure Categories
You can divide high blood pressure into five categories, according to guidelines from the American College of Cardiology:
- Normal: Normal blood pressure in adults is any blood pressure below 120/80.
- Elevated: In adults, elevated blood pressure is a systolic reading of 120-129 and a diastolic reading below 80.
- Hypertension stage I: This stage includes blood pressures ranges of 130-139 or 80-89 .
- Hypertension stage II: This stage includes blood pressures ranges above 140 or above 90 .
- Hypertensive crisis: Severely elevated blood pressure is defined as greater than 180 and/or 120 and associated with new or worsening organ damage.

Normal Blood Pressure Range
A normal blood pressure reading indicates that the heart and blood vessels are not working too hard pushing blood and that the blood is not exerting too much pressure on the walls of the vessels, says Aseem Desai, M.D., a cardiologist at Providence Mission Hospital in Southern California. Recent data from the American Heart Association suggests the optimal normal reading for adults over 20 is lower than 120/80 mmHgVirani S, et al. Heart disease and stroke statistics 2021 update . American Heart Association Journal. 2021 143:e254-e743. .
Dr. Desai notes blood pressure can vary depending on a persons age, gender, race and ethnicity, but it should still fall within the general normal range. While numbers lower than 120/80 are generally considered normal, Dr. Desai adds, The target blood pressure for treatment varies depending on age and associated co-morbidities .
Previously, guidance for normal blood pressure for adults varied by gender and specific age, but new data states normal blood pressure for adults as a collective is less than 120/80 mmHgHigh Blood Pressure Symptoms and Causes. Centers for Disease Control and Prevention. Accessed 7/16/2021. .
When it comes to race and ethnicity, Dr. Desai says certain groups have a higher rate of hypertension. Non-Hispanic Black people have a significantly higher rate of hypertension compared to non-Hispanic white people, and Hispanics and non-Hispanic Asians have lower rates than the first two, he says.
Cardiology : What Does Blood Pressure Really Mean
We have all had our blood pressure taken at a regular doctor visit however most of us dont truly understand why those numbers are so important. Having high blood pressure is a big health concern, but what does it all really mean?
What is blood pressure?
In the most basic terms, when your heart beats, it pumps blood throughout your body, supplying it with the oxygen and energy it needs. As your blood moves, it pushes against the sides of your blood vessels. The strength of this pushing is what is known as blood pressure.
When you have your blood pressure reading it consists of two numbers, presented as one number over the other, like a fraction. The first or top number is your systolic blood pressure. This is the amount of pressure in your arteries during the contraction of your heart muscle. The second or bottom number is your diastolic blood pressure. This is the lowest level your blood pressure reaches as your heart relaxes between beats. The numeric difference between your systolic and diastolic blood pressure is called your pulse pressure. For example, the pulse pressure reading for a person whose blood pressure is 120/80, would be 40. Along with blood pressure, pulse pressure can also provide insight into your heart health. In some cases a low pulse pressure may indicate poor heart function, while a higher pulse pressure may reflect leaky heart valves, often as a result of age-related losses in aortic elasticity.

Average Blood Pressure By Age
As you get older, your blood vessels tend to become stiffer and plaque can build up in them, which can raise your blood pressure. If your blood pressure becomes too high, you’re at a greater risk for heart disease, strokes, and more.
In 2015, the average blood pressure worldwide was 127/79 mm Hg in men, and 122/77 mm Hg in women, according to a study analysis published in Lancet.
When researchers for the National Center for Health Statistics looked at average blood pressure in U.S. adults between 2001 and 2008, the average reading was 122/71 mm Hg. The breakout was 124/72 mm Hg for men, and 121/70 mm Hg in women. It rose by age and was significantly higher in Black people.
The researchers found the following breakdown by age, sex, and race or ethnicity:
|Blood Pressure by Age|
As the population ages and life expectancy increases, high blood pressure is becoming more common.
Healthfda Once Again Expands Recall Of Blood Pressure Drugs
“Recognizing that the diastolic blood pressure also has to be controlled because it can increase risk for stroke is a good step forward in our management for blood pressure,” said Dr. Nieca Goldberg, a cardiologist at NYU Langone Medical Center and medical director of the Joan H. Tisch Center for Women’s Health, who was not involved with the research.
Over the past decade, mounting evidence has shown that when patients can get their blood pressure down to levels below what was previously considered “normal,” they greatly reduced their risk for heart attack and stroke.
In 2017, the American Heart Association and the American College of Cardiology for optimal blood pressure. Anyone with a measurement over 130/80 mmHg is considered to have hypertension.
Neither Goldberg nor other outside heart experts were surprised by the findings.
“This is something I’ve believed for years, that we should treat both systolic and diastolic blood pressure,” Dr. Angela Brown, an associate professor of medicine and clinical hypertension specialist at Washington University School of Medicine in St. Louis, wrote in an email to NBC News.
“I emphasize this point in training my students, residents and fellows because they often tend to ignore the diastolic pressure,” Brown said.
Brown also emphasized that younger people often have higher diastolic readings than systolic readings, such as 130/100mm Hg, compared with older people whose systolic readings may be higher, such as 170/80 mmHg.

In the past two years or so, many Americans suddenly found themselves faced with hypertension. For some 31 million, it wasnt an abrupt surge in blood pressure that put them in that category. It was the result of a new definition of high blood pressure from the American Heart Association and the American College of Cardiology in 2017.
Before then, blood pressure was considered borderline-high at 140/90. Now, a measurement as low as 130/80 is considered stage 1 hypertension.
Some experts say that redefining hypertension offers significant benefits. Theres a lot of therapeutic inertia in medicine, which means a lot of physicians were just shrugging their shoulders when patients were coming in with blood pressure readings of 135/85 instead of sitting them down and counseling them about their measurements, says Luke Laffin, M.D., a preventive cardiologist at the Cleveland Clinic. When you label it hypertension, both physicians and patients are more likely to take notice and act on it.
Here, what to know about the best numbers for you, and how to achieve them.
So You Have High Blood Pressure What Else Could Be Wrong
If you have high blood pressure, get checked for diabetes and high cholesterol. Most people who have high blood pressure also have some of the other risks for heart disease and stroke, such as not getting enough physical activity, having unhealthy eating habits, smoking, being overweight or drinking too much alcohol. Ask your doctor to test your kidney function through a blood and urine test, and through the electrolytes in your blood kidney problems can cause high blood pressure.

Why Does Blood Pressure Increase With Age
Doctors dont completely understand why blood pressure tends to rise with age. Blood pressure is the force of blood as it flows through the arteries. As you age, your arteries may narrow and become stiff. Narrow arteries lead to an increase in blood pressure. High blood pressure can damage the walls of the arteries and the heart itself.
In some cases, high blood pressure could be a result of lifestyle, the environment, certain medications, or other conditions such as sleep apnea, kidney disease, or thyroid problems.
Does High Blood Pressure Increase Heart Rate
Heart rate and blood pressure do not necessarily increase at the same rate. A rising heart rate does not cause your blood pressure to increase at the same rate. Even though your heart is beating more times a minute, healthy blood vessels dilate to allow more blood to flow through more easily. When you exercise, your heart speeds up so more blood can reach your muscles. It may be possible for your heart rate to double safely, while your blood pressure may respond by only increasing a modest amount.

Which Number Is More Important
Typically, more attention is given to systolic blood pressure as a major risk factor for cardiovascular disease for people over 50. 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 89.
What Can Cause A Short
Its normal for blood pressure to go up and down throughout the day. Things like exercise, stress, and sleeping can affect your blood pressure. Some medicines can cause a spike in blood pressure, including certain asthma medicines and cold remedies.
A low blood pressure reading can be caused by many things, including some medicines, a severe allergic reaction, or an infection. Another cause is dehydration, which is when your body loses too much fluid.

What Does A Blood Pressure Reading Look Like
When you have your , you will be given two numbers, a top number and a bottom number.
- Systolic blood pressure. This is the first, or top, number. This is the highest level your blood pressure reaches when your heart beats, forcing blood around your body.
- Diastolic blood pressure. The second number, or bottom number, is the lowest level your blood pressure reaches as your heart relaxes between beats.
Blood pressure is measured in millimetres of mercury . If the first number is 120 and the second number is 80, this would be written as 120/80mmHg, and youd call it 120 over 80.
This video explains more about systolic and diastolic blood pressure.
What Numbers Are Considered High Blood Pressure
Blood pressure above 140 mm Hg systolic and/or 90 mm Hg diastolic is considered hypertensive. There are 2 stages of hypertension. Stage 1 hypertension is systolic blood pressure between 140 to 159 mm Hg and/or diastolic blood pressure 90 to 99 mm Hg. Stage 2 hypertension is blood pressure greater than 160 mm Hg systolic and/or 100 mm Hg diastolic. When systolic and diastolic pressures fall into different categories, your healthcare professional should select the higher category to classify your blood pressure. For example, 160/80 mm Hg would be considered stage 2 hypertension.
If you are hypertensive and have begun receiving initial medication therapy, you will probably need to return for follow-up and adjustment of medications once a month until your blood pressure goal is reached. More frequent visits may be necessary for those with stage 2 hypertension.

What Do Blood Pressure Numbers Mean
Blood pressure is measured using two numbers:
The first number, called systolic blood pressure, measures the pressure in your arteries when your heart beats.
The second number, called diastolic blood pressure, measures the pressure in your arteries when your heart rests between beats.
If the measurement reads 120 systolic and 80 diastolic, you would say, 120 over 80, or write, 120/80 mmHg.
