Background: Cardiac computed tomography (CT) is increasingly used to search for cardioembolic sources of acute ischemic stroke (AIS). We assessed the association between high-risk cardioembolic sources on cardiac CT and AIS.
Methods: We performed a case-control study using data from a prospective cohort including consecutive adult patients with suspected stroke who underwent cardiac CT acquired during the initial stroke imaging protocol between 2018 and 2020.
Article Synopsis
- This study investigates the impact of left atrial appendage (LAA) slow-flow on ischemic stroke outcomes, finding that 16% of patients had slow-flow and shared characteristics with those having LAA thrombus.
- While both slow-flow and thrombus were linked to a higher prevalence of atrial fibrillation, patients with thrombus experienced more severe strokes and worse functional outcomes than those with slow-flow.
- Ultimately, slow-flow did not significantly affect functional outcomes or major cardiovascular events, but it was associated with an increased risk of stroke recurrence in patients with unknown causes of their strokes.
Background: Cardiac computed tomography (CT) acquired during the initial acute stroke imaging protocol (acute cardiac CT) is increasingly used to screen for cardioembolism, but information on the long-term clinical implications of its findings is lacking.
Methods And Results: We performed a prospective, single-center cohort study in which consecutive patients with ischemic stroke underwent ECG-gated acute cardiac CT and were followed up for 2 years. The primary outcome was functional outcome assessed using the modified Rankin Scale.
