Cardiovascular Groups Issue 2nd Universal Heart Failure Definition for 64 Million Adults
3 articles · Updated · Vancity Buzz · Jun 29
Summary
More than 64 million adults worldwide are affected by heart failure, and major cardiovascular groups have issued a new global definition to sharpen prevention, diagnosis and treatment.
The 2026 update replaces rigid ejection-fraction cutoffs with categories that account for sex, age and ethnicity, while adding a universal system to classify underlying causes.
The framework also shifts attention to people at risk or in early-stage disease before symptoms appear and treats heart failure as a condition that can improve, remit or worsen over time.
Published simultaneously in Circulation, JACC, European Heart Journal and Global Heart, the document updates the 2021 definition and is set to underpin the next AHA/ACC heart failure guideline due in late 2027.
