Heart risk after chemo: scientists hunt for clues in your blood
NCT ID NCT06353191
First seen Jun 27, 2026 · Last updated Aug 19, 2026 · Updated 4 times
Summary
This study is trying to understand why some people who get chemotherapy for cancer later develop heart issues, while others don't. Researchers will collect blood samples from 1,000 adults who have had chemotherapy, including those who had heart problems and those who didn't. By studying these samples, they hope to find biological markers that could predict who is at risk.
