In 2025, the American Heart Association and the American College of Cardiology updated the clinical guidelines for diagnosing high blood pressure. As a result, the number of U.S. adults classified as having hypertension increased significantly from about one in three to nearly half of the population. With such a drastic change in standards, particularly for an ailment already too familiar among all types of communities, it’s beneficial to examine who exactly is most at risk and how to detect, prevent, and circumvent the effects of “the silent killer”.
Understanding high blood pressure
Blood pressure refers to the force of blood pushing against the walls of the arteries as the heart pumps. Hypertension occurs when that force remains consistently higher than normal, placing added strain on the heart and blood vessels over time. It is a leading contributor to preventable heart disease and stroke deaths, second only to smoking.
Latest standards for hypertension
One major change in the ACC and AHA’s guidelines is the removal of the “prehypertension” category. Individuals who previously fell into that range are now classified as either having elevated blood pressure or Stage 1 hypertension, allowing for earlier intervention.
Under the updated guidelines:
- Normal: Less than 120/80 mm Hg
- Elevated: 120–129 systolic and less than 80 diastolic
- Stage 1 hypertension: 130–139 systolic or 80–89 diastolic
- Stage 2 hypertension: 140/90 mm Hg or higher
- Hypertensive crisis: 180/120 mm Hg or higher (requires immediate medical attention)
Other changes in the new guideline include:
- Only prescribing medication for Stage I hypertension if a patient has already had a cardiovascular event such as a heart attack or stroke or is at high risk of heart attack or stroke due to mitigating factors.
- Recognizing that many people will need two or more types of medications to control their blood pressure, and that people may take their pills more consistently if multiple medications are combined into a single pill.
- Identifying socioeconomic status and psychosocial stress as risk factors for high blood pressure that should be considered in a patient’s plan of care.
Disparities in Communities of Color
Anybody can experience high blood pressure, though several key factors can contribute to higher risk of developing the condition including health lifestyle, age, weight, race, and pre-existing ailments. According to the Centers for Disease Control, High blood pressure is more common in non-Hispanic Black adults (58%) than in non-Hispanic white adults (49%), non-Hispanic Asian adults (45%), or Hispanic adults (39%).
Black Americans, more likely to develop it at younger ages and experience more severe outcomes. Complications such as stroke, heart failure, and kidney disease occur at higher rates. These disparities are influenced by a combination of factors, including genetics, access to healthcare, socioeconomic conditions, and lifestyle choices such as diet and lack of exercise.
Black women also face increased risk during pregnancy, particularly with conditions such as preeclampsia, which is characterized by sudden high blood pressure and potential damage to the liver and kidneys.
Treatment and management
Treatment for hypertension typically begins with lifestyle modifications, including:
- Reducing sodium intake
- Maintaining a healthy weight
- Increasing physical activity
- Limiting alcohol consumption
- Quitting smoking
If lifestyle changes prove insufficient, medication may be prescribed. Many patients require more than one medication to effectively control their blood pressure, and combination therapies are often used to improve adherence and outcomes.
Early identification and consistent management of high blood pressure are critical. Routine monitoring, combined with appropriate lifestyle changes and medical care, can significantly reduce the risk of long-term complications.
