Blood Pressure Archive

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.

Beta blockers can slow one's heart rate, which can make gauging intensity during exercise difficult. Monitoring your breathing is a good way to ensure you work out at an intensity that is sufficient and not too high.

Many people have misconceptions about avoiding heart disease. One involves the use of over-the-counter fish oil capsules, which do not prevent heart disease in healthy people. Another relates to confusion about the ideal blood pressure targets in older adults. Some people are misinformed about the implications of a family history of heart disease, while others may be confused about the differences in heart attack symptoms between men and women.

No amount of alcohol, including red wine, is good for the heart, according to a policy brief from the World Heart Federation. Drinking, even in moderation, increases the risk for heart-related conditions such as hypertension, heart failure, stroke, cardiomyopathy (a disease of the heart muscle), aortic aneurysm (a dangerous bulge in the wall of the aorta), and atrial fibrillation (an irregular heart rhythm). People who drink regularly might benefit from reducing their intake.
