ClinConnect Summary

This study, called WATCH, is looking at a new way to keep an eye on heart health in people who have survived certain types of cancer, specifically lymphoma and sarcoma. Because some cancer treatments can affect the heart, the goal is to find a simple and affordable way to regularly check heart function over a long time. The study will use smartwatches and a special type of heart test called an ECG, which can be done using mobile devices with artificial intelligence (AI) to detect any early signs of heart problems.

People who might join the study are adults between 65 and 74 years old who have been diagnosed with lymphoma or sarcoma and have recently started, or finished within the past year, a type of cancer treatment known to affect the heart. To participate, they need to understand the study and agree to follow its steps. However, anyone who already has certain heart conditions, like weakened heart pumping or irregular heart rhythms, cannot join. Those in the study will wear a smartwatch that helps monitor their heart, making it easier to catch any heart issues early without frequent hospital visits. This approach aims to help cancer survivors stay healthier and prevent serious heart problems in the future.
