The American Heart Association (AHA) is sounding the alarm on high blood pressure, which remains the number one preventable risk factor for heart disease and stroke. According to new data from the AHA, approximately 125.9 million U.S. adults—47.3% of the adult population—now live with high blood pressure, an increase from previous years. Of those, only about 1 in 4 (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 AHA 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, and individuals can check their blood pressure at home with a monitor or at a pharmacy kiosk. If systolic pressure exceeds 180 or diastolic exceeds 120, it could be life-threatening, and emergency services should be called immediately if accompanied by symptoms such as chest pain, shortness of breath, back pain, numbness, weakness, vision changes, or difficulty speaking.
Lifestyle changes are the first line of defense. The AHA’s Life’s Essential 8 outlines key habits: eat smart, be active, quit tobacco and nicotine, sleep well, manage weight, manage blood pressure, manage cholesterol, and manage blood sugar. For those who still cannot control their blood pressure, safe and effective medications are available. The My Life Check calculator offers personalized tips.
New research confirms that high blood pressure can damage blood vessels in the brain, potentially leading to memory problems and dementia. Women face additional risks: high blood pressure during pregnancy can lead to serious complications and increase future heart risks. The AHA’s PREVENT risk calculator helps clinicians create personalized treatment plans by estimating 10- to 30-year risks of heart attack or stroke.
“Staying informed and taking action can help you and your loved ones live a longer, healthier life,” the AHA states. For more information, visit heart.org.
