NCT ID NCT05466825
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study brings together health data from about 3 million people across 40 countries to see how common risk factors like high blood pressure, smoking, and diabetes affect heart disease and death rates. Researchers want to understand how these risks differ by region and sex. No new treatments are tested; instead, the goal is to improve prediction of heart problems worldwide.
