White-coat hypertension refers to blood pressure that's high only when measured in a medical setting. It's defined as a reading in the doctor's office of greater than 130/80 (but less than 160/100) and an average daytime blood pressure reading of less than 130/80. If home monitoring reveals mostly normal readings, treatment may not be needed. But intermittent blood pressure spikes might still damage the heart.

Letting your arm dangle or rest in your lap (instead of being supported at heart level, as is recommended) during a blood pressure check can cause a falsely high reading, according to a 2024 study.

Eating cruciferous vegetables like broccoli and cauliflower may reduce blood pressure more than eating squash and root veggies.

U.S. guidelines define normal blood pressure as less than 120/80 millimeters of mercury (mm Hg). Studies have shown that the lower a person's blood pressure, the greater the heart health benefits. However, the "best" blood pressure number for someone depends on several factors, such as the person's health condition, lifestyle, family history, and personal goals. Depending on an individual's situation, a higher-than-normal number may be adequate.

A 2024 study found that the accuracy of a blood pressure reading is compromised if a person's arm isn't in a certain position. For the most effective measurement, the person should be seated, feet flat on the floor, with the arm supported so the elbow is at heart level.

A 2024 study suggests that swapping table salt for a salt substitute can markedly lower the risk of developing high blood pressure.

Renal denervation, a nondrug treatment for uncontrolled high blood pressure, works by disrupting some of the nerves surrounding the renal arteries, which supply the kidneys. Two systems are FDA-approved for people whose blood pressure remains high despite lifestyle changes and medications. Renal denervation lowers systolic blood pressure by an average of 8 to 9 points—about the same as what people get with a single blood pressure drug. But the response varies widely; some people experience more dramatic drops, while others have no response.

People who have stable angina despite taking medications can be treated with stents or bypass surgery. The best choice depends on the location and complexity of the artery blockages and other health conditions.
