Heart disease continues to be the leading cause of death in the United States, but new guidelines released in 2025 are changing how we approach cardiovascular health. Experts from the American Heart Association and the American College of Cardiology have introduced updated recommendations that focus on earlier intervention, personalized treatment, and lifestyle changes that can make a lasting impact.
One of the most notable changes is the adjustment in blood pressure thresholds. The new standard lowers the systolic target from 140 mm Hg to 130 mm Hg, based on recent studies showing that damage to the heart and blood vessels can begin at lower levels than previously believed. This means more people may be eligible for early treatment, potentially preventing heart attacks and strokes before they occur.

To help personalize care, the PREVENT™ risk calculator has been introduced. This tool allows healthcare providers to assess an individual’s risk of cardiovascular events based on factors like age, family history, and underlying health conditions. It marks a shift away from generic treatment plans toward more tailored strategies that reflect each person’s unique health profile.

The new guidelines recommend more frequent screenings starting at age 20, especially for those with a family history of heart disease or diabetes. LDL cholesterol targets are now individualized, with more aggressive treatment suggested for high-risk patients.
Diet and exercise remain central to heart health. The AHA continues to advocate for a plant-rich diet that includes fruits, vegetables, whole grains, nuts, and lean proteins. Americans are encouraged to limit salt intake to under 2,300 milligrams per day and reduce added sugars—no more than 36 grams daily for men and 25 grams for women. These recommendations aim to combat the hidden dangers of processed foods and sugary drinks.
Physical activity is another key focus. Adults should aim for at least 150 minutes of moderate exercise or 75 minutes of vigorous activity each week. Even short walks throughout the day can help counteract the effects of prolonged sitting. Waist circumference is now considered a more accurate measure of heart risk than body mass index (BMI), prompting a shift in how weight-related health is assessed.

High blood pressure has been linked to cognitive decline and dementia, making early detection and treatment even more critical. The updated guidelines emphasize the importance of regular monitoring to protect both the heart and the mind.
With these new recommendations, 2025 marks a turning point in cardiovascular care. By focusing on prevention, personalization, and early action, individuals have more tools than ever to take control of their heart health. Whether through diet, exercise, or regular screenings, small changes today can lead to a healthier tomorrow.
