Summary
Brief summary (as posted)
This study looks at how often atrial fibrillation (AF), an irregular heart rhythm, occurs in people with certain blood cancers who are starting a type of cancer medicine called a Bruton's tyrosine kinase inhibitor (BTKI). Researchers will follow 400 people starting BTKI therapy and compare them to 100 people with similar blood cancers who are not taking a BTKI. Participants will wear a smartwatch and, later, a heart monitor patch to check for AF and other irregular heart rhythms over 12 months. The study will also look at whether AF affects cancer treatment, such as needing to pause, lower the dose, or stop the BTKI, and whether it leads to other health problems such as bleeding, stroke, or heart-related hospital visits.

- label
- BTKI Therapy
- description
- Participants with chronic lymphocytic leukemia, Waldenstrom macroglobulinemia, mantle cell lymphoma, or marginal zone lymphoma who are newly initiated on Bruton's tyrosine kinase inhibitor (BTKI) therapy. Participants are offered a smartwatch at enrollment for continuous monitoring and receive a clinically indicated ECG patch monitor 6 months after initiation of therapy if AF has not already been detected.
- label
- Non-BTKI Therapy (Control)
- description
- Participants with the same hematologic malignancy diagnoses who are newly initiated on non-BTKI therapy (e.g., venetoclax-based regimens) instead of a BTKI. Participants are offered a smartwatch at enrollment for continuous monitoring and receive a clinically indicated ECG patch monitor 6 months after initiation of therapy if AF has not already been detected.
Primary outcomes (1)
- measure
- Incidence of Atrial Fibrillation
- timeFrame
- Up to 12 months
- description
- Incidence of new atrial fibrillation (AF) detected by smartwatch photoplethysmography with confirmatory ECG, and/or by 14-day ECG patch monitor, compared between participants on BTKI therapy and non-BTKI control participants.
