“Beware of the American Heart Association’s (AHA) 'Salty Six' — six popular foods that can add high levels of sodium to your diet,” says Rachel Johnson, PhD, a professor of nutrition at the University of Vermont in Burlington and the former chair of the AHA’s nutrition committee. The Salty Six include breads and rolls, cold cuts and cured meats, sandwiches, pizza, soup, and chicken.
Pulse pressure (the difference between systolic and diastolic blood pressure) is frequently increased in older people with hypertension. This can mean that systolic pressure is abnormally high, but diastolic pressure may be normal or low a condition termed isolated systolic hypertension.[59] The high pulse pressure in elderly people with hypertension or isolated systolic hypertension is explained by increased arterial stiffness, which typically accompanies aging and may be exacerbated by high blood pressure.[60]

Many mechanisms have been proposed to account for the rise in peripheral resistance in hypertension. Most evidence implicates either disturbances in the kidneys' salt and water handling (particularly abnormalities in the intrarenal renin–angiotensin system)[61] or abnormalities of the sympathetic nervous system.[62] These mechanisms are not mutually exclusive and it is likely that both contribute to some extent in most cases of essential hypertension. It has also been suggested that endothelial dysfunction and vascular inflammation may also contribute to increased peripheral resistance and vascular damage in hypertension.[63][64] Interleukin 17 has garnered interest for its role in increasing the production of several other immune system chemical signals thought to be involved in hypertension such as tumor necrosis factor alpha, interleukin 1, interleukin 6, and interleukin 8.[65]

Hypertension is diagnosed on the basis of a persistently high resting blood pressure. The American Heart Association recommends at least three resting measurements on at least two separate health care visits.[74] The UK National Institute for Health and Care Excellence recommends ambulatory blood pressure monitoring to confirm the diagnosis of hypertension if a clinic blood pressure is 140/90 mmHg or higher.[75] 

Blood pressure is written as two numbers, such as 112/78 mm Hg. The top, systolic, number is the pressure when the heart beats. The bottom, diastolic, number is the pressure when the heart rests between beats. Normal blood pressure is below 120/80 mm Hg. If you’re an adult and your systolic pressure is 120 to 139, or your diastolic pressure is 80 to 89 (or both), you have pre-hypertension. High blood pressure is a pressure of 140 systolic or higher and/or 90 diastolic or higher that stays high over time.
Changes in blood vessel structure. Blood vessels have layers of the proteins elastin and collagen. Elastin is what makes blood vessels flexible. Collagen, which is stiffer, gives vessels structure. With age, elastin breaks down. Even the elastin that remains becomes less elastic. Meanwhile, collagen deposits in the vessels increase. As a result, blood vessels grow thicker and bend less easily over time. These changes may lead to higher systolic blood pressure.
Blood pressure guidelines show the lower the blood pressure numbers the better. As long as no symptoms of trouble are present there is no one number that doctors consider being too low. The guidelines call for an individualized, risk-based approach to managing hypertension, as well as a personal consultation with a health care provider. While the new guidelines mean we are more aggressive about blood pressure control, lifestyle changes are always a part of the treatment plan. A treatment plan is agreed to by patient and provider, and includes ongoing communication to see how the patient is feeling and how their medications are working.
If you suddenly find yourself with high blood pressure (hypertension) under the new guidelines from the American Heart Association and the American College of Cardiology, you might be wondering what to do. The guidelines, which were released in November, lowered the definition for high blood pressure to 130/80 from 140/90 millimeters of mercury (mm Hg), meaning more women now meet the criteria for stage 1 hypertension.
Unlike the smooth action of the hot tub pump, the human heart expands and contracts mightily each second or so, causing your blood pressure to be comparatively high one moment, and comparatively low in the next. That is why we need two measurements when checking your blood pressure: one at the moment when the pressure is highest (your systolic blood pressure), and one a moment later, when the pressure is lowest (your diastolic blood pressure).
Blood pressure readings fall into four general categories, ranging from normal to stage 2 high blood pressure (hypertension). The level of your blood pressure determines what kind of treatment you may need. To get an accurate blood pressure measurement, your doctor should evaluate your readings based on the average of two or more blood pressure readings at three or more office visits.

One reason to visit your doctor regularly is to have your blood pressure checked. Routine checks of your blood pressure will help pick up an early rise in blood pressure, even though you might feel fine. If there's an indication that your blood pressure is high at two or more checkups, the doctor may ask you to check your blood pressure at home at different times of the day. If the pressure stays high, even when you are relaxed, the doctor may suggest exercise, changes in your diet, and, most likely, medications.
It is important to go to your regular check-ups with your doctor. Hypertension is a common condition and, if caught, can be treated with medication to prevent complications. However, if you experience any of the symptoms of hypertension, such as frequent headaches, recurrent dizziness, nosebleeds, shortness of breath, nausea or vomiting, don't wait—speak to your doctor immediately.
High blood pressure is a common and dangerous condition. Having high blood pressure means the pressure of the blood in your blood vessels is higher than it should be. But you can take steps to control your blood pressure and lower your risk of heart disease and stroke. About 1 of 3 U.S. adults—or about 75 million people—have high blood pressure.1 Only about half (54%) of these people have their high blood pressure under control.1 Many youth are also being diagnosed with high blood pressure.2 This common condition increases the risk for heart disease and stroke, two of the leading causes of death for Americans.3 Get more quick facts about high blood pressure, or learn more about high blood pressure in the United States.

We stimulate high-impact research. Our Trans-Omics for Precision Medicine (TOPMed) Program includes participants with high blood pressure, which may help us understand how genes contribute to differences in disease severity and how patients respond to treatment. The NHLBI Strategic Vision highlights ways we may support research over the next decade, including new efforts for studying high blood pressure.


My blood pressure is 120/84 with a pulse of 94. 30 minutes prior to that it was 118/85 with a pulse rate of 101. I wasn’t doing anything but just sitting. I’ve noticed that my pulse is always between 85-99. I’ve seen a cardiologist and my stress test and echocardiogram has all come back normal. Should I be concern with these numbers. I have an autoimmune disease but I’m not sure if that would cause the fluctuations. Can someone help or make suggestions? Thanks


The medical world experienced yet another guideline update in 2018 telling doctors more medication is better. This guideline for treating hypertension was put out by the American College of Cardiology and the American Heart Association, and effectively lowered the definition of hypertension from 140/90 down to 130/80. The organizations also recommended drug treatment for all individuals with blood pressure greater than 140/90, regardless of underlying risk.
When a blood pressure reading is taken, the higher number represents the systolic pressure and the lower number represents the diastolic pressure. For example: 120/80 (120 over 80) in an adult means that the systolic pressure is 120 and the diastolic pressure is 80. As kids grow, their blood pressure increases from a systolic pressure of about 70–90 (as babies) to adult values (when they're teens).

Because of the need for emergency care, it is important to recognize the early signs of malignant hypertension. The first giveaway is blood pressure of 180/120. You might have bleeding in the eyes due to rupture of the small blood vessels. Other malignant hypertension symptoms can include chest pain, dizziness, a headache, numbness in your extremities, and confusion.

In general, lower doses of blood pressure medicine are as effective as higher doses and cause fewer side effects. So, when trying to find effective single-drug therapy, doctors usually begin with a low dose. They may decide to increase the dose a bit if the initial dose is ineffective—but it is rarely useful to “push” the dose of a single-drug therapy into the higher dosage ranges. Instead, if a drug fails to work at a relatively low dose, it is time to switch to a low dose of a different drug.

The JAMA study was an extensive chart review of over 38,000 patients at low risk for heart disease who had stage two hypertension (blood pressure between 149/90 and 159/99) and were treated with blood pressure medications. Over an average follow-up time of almost six years, they found no reduction in the risk of cardiovascular disease events or risk of death with medication use. They did, however, find an increased risk for low blood pressure, fainting, and acute kidney injury among those treated with medications.
Serum creatinine is measured to assess for the presence of kidney disease, which can be either the cause or the result of hypertension. Serum creatinine alone may overestimate glomerular filtration rate and recent guidelines advocate the use of predictive equations such as the Modification of Diet in Renal Disease (MDRD) formula to estimate glomerular filtration rate (eGFR).[27] eGFR can also provide a baseline measurement of kidney function that can be used to monitor for side effects of certain anti-hypertensive drugs on kidney function. Additionally, testing of urine samples for protein is used as a secondary indicator of kidney disease. Electrocardiogram (EKG/ECG) testing is done to check for evidence that the heart is under strain from high blood pressure. It may also show whether there is thickening of the heart muscle (left ventricular hypertrophy) or whether the heart has experienced a prior minor disturbance such as a silent heart attack. A chest X-ray or an echocardiogram may also be performed to look for signs of heart enlargement or damage to the heart.[23]

Hypertension Stage 1 is when blood pressure consistently ranges from 130-139 systolic or 80-89 mm Hg diastolic. At this stage of high blood pressure, doctors are likely to prescribe lifestyle changes and may consider adding blood pressure medication based on your risk of atherosclerotic cardiovascular disease (ASCVD), such as heart attack or stroke.
When discussing blood pressure issues, the healthcare professional may ask questions about past medical history, family history, and medication use, including prescriptions, over-the-counter medications, herbal remedies, and food additives. Other questions may include lifestyle habits, including activity levels, smoking, alcohol consumption, and illegal drug use.
