Detection and Significance of Nonsustained Ventricular Tachycardia in a Post-Stroke Population
Authors' conclusion
NSVT in patients with recent stroke or TIA is independently associated with a 2- to 3-fold increased risk of subsequent stroke, cardiac events, and death after controlling for demographics and clinical factors.
Study context
- Population
- Patients after ischemic stroke or transient ischemic attack (TIA) referred for ambulatory cardiac rhythm monitoring (CAMPS), 2019–2023completed monitoring
- Participants
- 752 patients
- Exposure
- Nonsustained ventricular tachycardia (NSVT) vs no NSVT
- Outcome
- Prevalence of NSVT and its association with subsequent stroke, cardiac events or death
