Why the target is a decision and not a lookup

Four major sets of guidance, all built from the same body of clinical trials, land on different targets.

The 2025 guideline from the American Heart Association and the American College of Cardiology recommends a goal below 130/80 mm Hg for most adults on treatment. The American Academy of Family Physicians, in its own 2022 guideline, strongly recommends treating to below 140/90 mm Hg and suggests that health care professionals consider a lower goal of below 135/85 mm Hg to reduce heart attacks. The 2024 European Society of Cardiology guideline asks health care professionals to aim for a systolic (top) number of 120 to 129 mm Hg when treatment is well tolerated, with more relaxed goals for some older and frailer adults. Kidney specialists writing the 2021 KDIGO guideline for chronic kidney disease recommend a systolic goal below 120 mm Hg, but only when pressure is measured with a careful standardized office technique.

In October 2025 the family physicians' academy formally declined to give the new national guideline its full endorsement, in part because the academy's own guidance does not support a universal goal below 130/80 mm Hg.

The groups differ because a lower target is a trade, and the SPRINT trial, published in 2015, shows both sides of it. It enrolled 9,361 adults age 50 and older who had a systolic pressure of 130 mm Hg or higher plus at least one added risk factor for heart disease. Half were treated toward a systolic goal below 120 mm Hg and half toward below 140 mm Hg. Over a median of about 3.3 years, the group with the lower goal had a rate of heart attack, stroke, heart failure, or cardiovascular death of about 1.65 percent per year, compared with about 2.19 percent per year in the standard group. Deaths from any cause were about 27 percent less frequent. The lower goal also came with more serious episodes of low blood pressure (2.4 versus 1.4 percent), fainting (2.3 versus 1.7 percent), abnormal blood salts (3.1 versus 2.3 percent), and sudden kidney injury (4.1 versus 2.5 percent).

The family physicians' review of the same body of evidence found that lower targets required about one additional blood pressure medicine on average, prevented roughly 4 heart attacks per 1,000 people over about 3.7 years, and raised the number of people with adverse events from about 7 in 100 to about 10 in 100.

Which target are you using for me, and where does it come from?

Ask for both numbers, systolic and diastolic, and ask which guideline or reasoning they come from. Then ask a follow up: is that an office number or a home number? The two are not always the same, and a separate article in this series covers the differences between office, home, and ambulatory readings.

Suppose the answer is "below 130/80 at home." Now a morning average of 134/78 means something specific: the top number is a few points above where your health care professional wants it, and the bottom number is fine. Without the target, the same reading is just a source of worry.

The second question in this pair is about risk: what is my 10 year PREVENT risk, and how did it shape the plan? PREVENT, short for Predicting Risk of cardiovascular disease EVENTs, is a calculator the American Heart Association released in 2023, built from the records of more than 6.5 million adults. It applies to adults ages 30 to 79 who do not already have known heart or blood vessel disease. It uses your age, sex, systolic blood pressure, cholesterol numbers, kidney function, body mass index, diabetes status, smoking status, and whether you take blood pressure or cholesterol medicine to estimate the chance of a heart attack, stroke, or heart failure over the next 10 years.

That estimate matters because the 2025 guideline uses it to sort people whose readings fall in the range it calls stage 1 hypertension (130 to 139 systolic or 80 to 89 diastolic). For those adults, the guideline recommends medicine along with lifestyle changes when they already have cardiovascular disease, a prior stroke, diabetes, or chronic kidney disease, or when their 10 year PREVENT risk is 7.5 percent or higher. When the risk is below 7.5 percent, the guideline recommends 3 to 6 months of lifestyle changes first, with medicine recommended if readings stay at 130/80 mm Hg or higher. At 140/90 mm Hg or higher, the guideline recommends medicine plus lifestyle changes without waiting.

So the practical question is: which of those paths am I on? Ask for your risk as a plain percentage. Seven percent and 9 percent look similar but sit on opposite sides of the guideline's line.

Do I have a reason for a gentler target?

SPRINT included adults 75 and older, and they benefited at least as much as younger participants. But it excluded people with diabetes, people who had already had a stroke, people living in nursing homes or assisted living, people with dementia, and anyone whose systolic pressure fell below 110 mm Hg when standing. If several of those describe you, a fair question is: do I resemble the people in the studies behind my target?

The European guideline names the situations in which it expects health care professionals to relax the goal: age 85 or older, moderate to severe frailty, symptomatic drops in pressure on standing, and limited life expectancy. In those cases it advises aiming for a pressure that is "as low as reasonably achievable" rather than a fixed number. The 2025 United States guideline names institutional care and limited life expectancy as reasons to individualize. Neither says older adults should be left untreated.

Two things you notice at home belong in this conversation: falling or nearly falling, and dizziness or lightheadedness when you stand up, especially soon after getting out of bed or after a meal. These can be signs of orthostatic hypotension, a drop in blood pressure on standing. The European guideline defines it as a fall of 20 mm Hg or more in the systolic number, or 10 mm Hg or more in the diastolic number, within 1 to 3 minutes of standing, and it says everyone with high blood pressure should be checked for it at the first visit and again whenever symptoms suggest it.

That leads to a simple request: could you check my pressure sitting and then standing? Many clinics do not do this unless asked. If the drop is large or you have symptoms, your health care professional may reconsider the target, the medicines, or the timing of doses. Do not skip or reduce a dose on your own because you felt woozy once. Report it promptly instead, and ask what to do if it happens again.

The American Heart Association describes readings below 90/60 mm Hg as the usual marker for low blood pressure, and it lists dizziness, fainting, confusion, and blurred vision as symptoms that matter. Some blood pressure medicines, including diuretics and beta blockers, are among the causes. Ask what low reading, or what symptom, should prompt a call from you.

How should I measure at home, and what home average counts?

The 2025 guideline gives home monitoring its strongest rating, both to confirm a diagnosis and to track treatment. It also publishes a table matching office and home numbers. An office reading of 130/80 mm Hg corresponds to a home reading of 130/80 mm Hg. An office reading of 140/90 mm Hg corresponds to a home reading of about 135/85 mm Hg, which is also the equivalent daytime ambulatory average, while the 24 hour ambulatory equivalent is 130/80 mm Hg.

So if your health care professional follows the family physicians' below 140/90 mm Hg goal, the matching home number is closer to 135/85 mm Hg. Ask directly: what home average would you like to see, and over how many days?

Guidelines base decisions on the average of repeated readings, not on the highest reading you happened to catch. The European guideline describes a standard routine: two readings 1 to 2 minutes apart, morning and evening, during the same periods each day, for at least 3 days and up to 7. Ask whether your clinic wants that full set before an appointment, and whether to bring the monitor so its readings can be checked against the office equipment.

If your target is unusually low, ask one more measurement question. In SPRINT, pressure was measured with an automated device that took several readings after a rest period, a method that tends to produce lower numbers than a single quick reading in a busy clinic. The kidney guideline that recommends a systolic goal below 120 mm Hg says it applies only to standardized measurement, and that no reliable correction factor converts a casual office reading into a standardized one. If you are told your target is 120 systolic, ask how your pressure will be measured when you are compared against it.

Could anything else I take be pushing my numbers up?

The 2025 guideline lists substances that can raise blood pressure or work against blood pressure medicine: alcohol, caffeine above about 300 milligrams a day, nonprescription decongestants such as pseudoephedrine and phenylephrine, common nonsteroidal pain relievers such as ibuprofen and naproxen, some antidepressants, oral contraceptives, corticosteroids, certain cancer treatments, black licorice, and a few herbal products. The guideline estimates that about 1 in 5 adults with high blood pressure regularly uses a nonprescription medicine that may raise pressure or interfere with treatment.

Bring a complete list to your appointment, including every prescription, every nonprescription medicine, and every vitamin and supplement, and ask: could any of these be raising my readings or working against my treatment? If a pain reliever or a cold medicine is on the list, ask whether there is an option for that problem that does not affect blood pressure.

What number should make me call, and whom?

The first threshold comes from the American Heart Association. If your monitor shows 180/120 mm Hg or higher, wait at least 1 minute and take it again. If it is still that high and you have no symptoms, this is considered severe hypertension. It usually does not require a hospital visit, but you should contact your health care professional as soon as possible. If a reading of 180/120 mm Hg or higher comes with chest pain, shortness of breath, back pain, numbness or weakness, a change in vision, or difficulty speaking, it is a medical emergency. Call 911. Do not wait to see whether the pressure comes down on its own.

The second threshold is personal, and only your health care professional can set it. Ask: below the emergency level, what pattern should prompt me to send a message? A useful answer sounds like "a week of morning averages above 145" or "any reading below 100 systolic with dizziness." Then ask whom to contact and how, since some clinics prefer a portal message and some a nurse line.

Finally, ask when the target itself will be revisited. After a change in medicine, guidelines generally expect a recheck within weeks, not months, and a home log during that window makes the recheck useful.

Questions for particular situations

If you are pregnant or planning a pregnancy, the numbers change. The American Heart Association describes a healthy pregnancy blood pressure as below 140/90 mm Hg, high blood pressure in pregnancy as 140 or higher systolic or 90 or higher diastolic, and a severe range of 160 or higher systolic or 110 or higher diastolic, which calls for care right away. A severe reading with a bad headache, vision changes, abdominal pain, chest pain, marked swelling, or shortness of breath is a reason to call 911. High blood pressure found before 20 weeks is called chronic hypertension, and after 20 weeks gestational hypertension. A blood pressure check within 3 to 10 days of going home after delivery is recommended. Ask your obstetric team what thresholds apply to you now, how often to measure, and whom to call after hours.

If you have chronic kidney disease, ask whether your kidney specialist and your primary care health care professional are using the same target, since the kidney guideline's systolic goal below 120 mm Hg may differ from the number in your primary care chart.

If you have diabetes, coronary artery disease, or a prior stroke, ask how that changed your target and your timeline, since the 2025 guideline treats those conditions as a reason to consider medicine at stage 1 readings rather than after a trial of lifestyle changes.

Getting the most from the conversation

Bring your monitor and your log, or at least your averages for the past week. Bring the complete medicine and supplement list. Write down anything you have noticed at home: dizziness on standing, a near fall, headaches after a dose, swelling, unusual tiredness. If a family member or care partner helps with your medicines, bring them, or bring their questions.

Then aim to leave with a single sentence you could repeat to a pharmacist: "My target is below this systolic and this diastolic number, measured at home in the morning and evening, and we will review it on this date." If you get a vague answer, a polite way to sharpen it is to ask what number would make your health care professional change the plan.

A short version to copy onto a card or into your phone:

1. 1 What blood pressure target are you using for me, and which guideline or reasoning is it based on?
2. 2 Is that an office number or a home number, and what home average would you like to see over how many days?
3. 3 What is my 10 year PREVENT risk, and how did it affect whether you recommended medicine now or lifestyle changes first?
4. 4 Do I have any reason for a gentler target, such as my age, frailty, falls, dizziness, other illnesses, or the number of medicines I take?
5. 5 Could you check my pressure sitting and then standing?
6. 6 Could anything on my medicine, vitamin, and supplement list be raising my readings or working against my treatment?
7. 7 What high reading, what low reading, and what symptoms should prompt me to contact you, and how do I reach you?
8. 8 When will we review this target again, and what should I bring to that visit?

Most take a sentence to answer. If you can ask only two, ask the first two.
