Nearly half of U.S. adults have high blood pressure, and many don’t know it or don’t have it under control. In August 2025, the American Heart Association (AHA) and American College of Cardiology (ACC) released their first full blood pressure guideline update since 2017. Here’s what changed and what stayed the same.
What stayed the same
The blood pressure categories are unchanged:
- Normal: below 120/80
- Elevated: 120–129 systolic and below 80 diastolic
- Stage 1 hypertension: 130–139 or 80–89
- Stage 2 hypertension: 140/90 or higher
The treatment goal for most adults is still below 130/80. Learn more in blood pressure numbers explained.
What’s new
- Earlier treatment: For people with stage 1 hypertension and lower risk, the guideline recommends starting medication if blood pressure stays above 130/80 after 3 to 6 months of lifestyle changes. Higher-risk people should start medication right away.
- A new risk calculator: Doctors now use the PREVENT calculator to estimate 10-year risk of heart disease and stroke. It includes kidney function and doesn’t use race.
- Brain health: The guideline highlights that controlling blood pressure lowers the risk of cognitive decline and dementia.
- Combination pills: Starting with two medicines in a single pill is encouraged for many people with stage 2 hypertension, to reach goals faster. See types of blood pressure medicines.
- Salt substitutes: Potassium-based salt substitutes are recommended for many people to lower sodium, unless they have kidney disease or take medicines that raise potassium.
- Alcohol: The guideline advises limiting alcohol, ideally avoiding it, to help lower blood pressure.
Lifestyle still comes first
Healthy habits remain the foundation of treatment and can lower blood pressure by 5 to 10 points or more:
- Eat less sodium, ideally under 1,500 mg a day. Try our tips for cutting sodium.
- Follow the DASH diet, rich in fruits, vegetables and low-fat dairy.
- Be active most days. Our brisk walking plan is a good start.
- Keep a healthy weight, sleep well and manage stress.
Check at home
Home monitoring helps confirm a diagnosis and track treatment. Learn how to measure blood pressure at home correctly.
What this means for you
- Know your numbers. If you’re in stage 1, ask your doctor about your PREVENT risk score.
- If lifestyle changes haven’t brought you below 130/80 in a few months, ask whether medication is right for you.
- Ask before using a salt substitute if you have kidney disease or take certain heart or blood pressure medicines.
The bottom line
The new guideline keeps the same numbers but pushes for earlier, more effective treatment, with a clearer focus on protecting the heart, kidneys and brain. Untreated high blood pressure damages organs silently, so take it seriously.
Common questions
Is 130/80 high blood pressure?
Yes. A reading of 130/80 or higher on repeated measurements is considered stage 1 hypertension.
What is the PREVENT calculator?
It’s a tool that estimates your risk of heart attack, stroke and heart failure over 10 and 30 years, using factors like age, cholesterol, blood pressure, diabetes, smoking and kidney function.
Do I need medicine if my blood pressure is 132/84?
It depends on your overall risk. Many people at lower risk start with lifestyle changes for 3 to 6 months. If blood pressure stays above 130/80, medication may be recommended.
Are potassium salt substitutes safe for everyone?
No. People with kidney disease or who take medicines that raise potassium, such as some blood pressure drugs, should ask their doctor first.
