Summary

This trial will help us better understand the role of LAA thrombi in ESUS and identify risk factors for stroke recurrence. #ESUS #CryptogenicStroke #TEE #CTA #LAAThrombi

Who is the study for?
The DAYLIGHT trial is for adults who come to the emergency department or stroke clinic with a suspected stroke or mini-stroke. They don't need a confirmed diagnosis to join. However, pregnant individuals, those with severe kidney disease, past or active cancers of the head, neck, or chest; allergies to iodine-based contrast agents; or without vein access for IV contrast are excluded.
What is being tested?
This study tests if an extended CT angiography (eCTA) can better detect blood clots in the heart's left atrial appendage compared to standard CT angiography (sCTA). Both groups will receive usual care for stroke evaluation but one group will have additional imaging extending below the carina.
What are the potential side effects?
Potential side effects mainly relate to CTA and may include reactions to contrast dye like rash or itching, kidney function impairment especially in those already at risk, and discomfort from lying still during scanning.

Study Objectives

Study objectives can provide a clearer picture of what you can expect from a treatment.
Primary study objectives
Primary Efficacy Outcome: The proportion of participants with a confirmed or "highly suspected" newly diagnosed cardioaortic thrombus
Secondary study objectives
Secondary Efficacy Outcome 1: The proportion of participants diagnosed with a cardio-aortic embolic source that has an available guideline-supported treatment including thrombi, vegetations, and tumors.
Secondary efficacy outcome 2: The proportion of participants diagnosed with a cardio-aortic embolic source known to increase the risk of stroke.
Secondary efficacy outcome 3: The proportion of participants diagnosed with a cardio-aortic embolic source resulting in the initiation of a new secondary prevention treatment other than antiplatelet therapy.
Other study objectives
Primary Safety Outcome 1: door to sCTA time vs door to eCTA
Secondary Safety Outcome 1: Door-to-needle
Secondary Safety Outcome 2: Door-to-groin puncture
