Heart shield: common drug may prevent Chemo-Induced cardiac harm
NCT ID NCT07370506
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether telmisartan, a blood pressure medication, can prevent heart damage caused by the chemotherapy drug doxorubicin in breast cancer patients. Researchers will enroll 36 newly diagnosed women and measure changes in heart function and injury markers. If effective, this approach could make chemotherapy safer without reducing its cancer-fighting power.
