The American Heart Association is raising awareness about high blood pressure, the leading preventable risk factor for heart disease and stroke, as new data shows that nearly half of U.S. adults now have the condition, with many unaware. According to the Association, approximately 125.9 million (47.3%) of all U.S. adults are living with high blood pressure, an increase from previous years, and only about 1 in 4 adults (25.6%) have it under control. In 2023, high blood pressure was a primary or contributing factor in the deaths of more than 664,470 people in the U.S., nearly equivalent to the passenger capacity of over 1,300 jumbo jets.
“Heart health is intensely personal, and scientific research shows us that one of the most important things you can do to be heart healthy is to manage your blood pressure,” said Keith C. Ferdinand, M.D., FAHA, FACC, volunteer co-vice chair of the writing committee for the Association’s 2025 high blood pressure guidelines and chair in preventative cardiology at Tulane University School of Medicine. “When you have high blood pressure, it's not just a number on a chart - it's your future at stake; it's your ability to stay present for the people you love. The first step is awareness.”
The Association emphasizes the importance of knowing your numbers. Normal blood pressure is defined as systolic pressure less than 120 and diastolic pressure less than 80. Regular monitoring is crucial, whether at a doctor's office, with a home blood pressure monitor, or at a pharmacy kiosk. An extremely high reading—systolic above 180 or diastolic above 120—can be life-threatening, especially with symptoms like chest pain, shortness of breath, back pain, numbness, weakness, vision changes, or difficulty speaking, requiring immediate medical attention.
Lifestyle changes are the first line of defense. The American Heart Association’s Life’s Essential 8 outlines key habits: eat smart, be active, quit tobacco and nicotine, sleep well, manage weight, and control blood pressure, cholesterol, and blood sugar. For those who need additional help, safe medications are available. The My Life Check Calculator offers personalized tips.
New research confirms that high blood pressure can damage brain blood vessels, leading to memory problems and dementia. Women face special risks; managing blood pressure before, during, and after pregnancy is critical to avoid complications and future heart issues. The American Heart Association’s PREVENTTM risk calculator helps doctors create personalized plans, estimating heart attack or stroke risk over 10 to 30 years.
“One high reading isn’t usually cause for concern, although, if your blood pressure is consistently high, talk to your clinician about next steps,” said Ferdinand. “However, an extremely high reading could be dangerous, especially if you are not exerting yourself or if you have certain other symptoms. Do not ignore that.” The Association urges everyone to talk to their doctor and take action to protect their health. For more information, visit heart.org.
