If you had a blood pressure reading of 134 over 82 at your last checkup, there is a fair chance the conversation ended with advice to cut back on salt and come back in a year. Under the newest national guideline, that conversation may go differently.
In August 2025 the American Heart Association and American College of Cardiology, along with 11 other professional societies, published an updated guideline on high blood pressure1, replacing the version from 2017. Much of it is technical, written for clinicians managing complicated cases. A handful of changes, however, reach directly into routine primary care visits, and they are worth understanding before your next one.
The line stayed where it was
The categories are unchanged. A reading below 120 over 80 is normal. A top number of 120 to 129 with a bottom number under 80 is elevated. Readings of 130 to 139 over 80 to 89 are stage 1 hypertension, and 140 over 90 or higher is stage 2. The American College of Cardiology3 notes that the treatment goal for most adults remains below 130 over 80.
Nearly half of American adults meet the definition of hypertension, and many do not know it, because high blood pressure rarely causes symptoms until it has already done damage.
A new way to calculate risk
The biggest practical change is how clinicians decide who needs medication at stage 1. The old guideline relied on a risk tool called the pooled cohort equations. The new one uses PREVENT2, a calculator the American Heart Association developed from a large and more diverse population. PREVENT folds in measures of kidney and metabolic health along with the usual cholesterol, age and smoking status.
Under the new guideline, an adult with stage 1 hypertension and an estimated 10-year cardiovascular risk of 7.5 percent or higher by PREVENT should start medication along with lifestyle changes. So should anyone at stage 1 who already has heart disease, diabetes or chronic kidney disease. People at stage 1 with lower risk start with lifestyle changes and add medication if their pressure is still at or above 130 over 80 after three to six months.
At stage 2, medication starts right away, and the guideline prefers starting with two drugs, ideally combined in a single pill. One pill is easier to remember than two, and starting with a combination brings pressure down faster.
Two tests that used to be optional
The guideline now recommends a urine albumin-to-creatinine ratio for everyone diagnosed with hypertension. This simple urine test detects small amounts of protein leaking through the kidneys, an early sign of damage that also raises heart risk. It used to be optional. Now it is standard.
It also recommends screening for primary aldosteronism in anyone whose pressure stays high despite treatment. This hormone disorder, in which the adrenal glands produce too much aldosterone, is more common than once thought and is treatable, sometimes with surgery. The new guideline makes clear that testing should happen whether or not potassium is low, since many people with the condition have normal potassium levels.
The brain gets a place in the guideline
For the first time, the guideline explicitly ties blood pressure treatment to brain health. It recommends treating adults with hypertension to a top number below 130 in part to reduce the risk of mild cognitive impairment and dementia. High blood pressure is one of the 14 modifiable dementia risk factors identified by the Lancet Commission, a list that also includes hearing loss.
Measure at home, and do it properly
The guideline strongly encourages home monitoring to confirm a diagnosis and track treatment. Office readings can run high because of stress, known as white coat hypertension, or occasionally low.
Technique matters more than most people realize. The CDC advises4 sitting with your back supported and feet flat on the floor, resting the arm on a table at chest height, placing the cuff on bare skin and not talking during the reading. Crossed legs and a dangling arm can each push the number up. Take two readings a minute apart and record both.
Use a validated upper-arm cuff. The guideline advises against relying on cuffless devices such as smartwatches, because their accuracy has not been established.
The basics still come first
Lifestyle advice remains the foundation for everyone. The guideline points to the American Heart Association's Life's Essential 8, which covers diet, physical activity, sleep, weight and not smoking. It also recommends potassium-based salt substitutes as a way to cut sodium for most people, though anyone with kidney disease or taking medications that raise potassium should check with a clinician first.
If you know your last reading was in the 130s, bring a week of home readings to your next visit and ask what your PREVENT risk is. Those two pieces of information now drive most of the decision.
