Identifying stroke risk in heart surgery patients

Left Atrial Appendage Arrhythmogenic and Thrombogenic Substrate

Not applicable Interventional University Hospital Bispebjerg and Frederiksberg · NCT06405750

This study is trying to see if looking at heart scans can help find patients at risk of strokes before they have heart surgery.

What this trial studies

This project aims to determine if patients at risk of forming blood clots, which can lead to strokes, can be identified through electrocardiogram analysis. Patients scheduled for elective heart surgery will have their left atrial appendage closed, a common procedure for those with atrial fibrillation. During surgery, tissue from the appendage will be collected for analysis alongside blood samples and ECG data. The study will investigate thrombosis factors and inflammatory markers to better understand the arrhythmogenic and thrombogenic substrates.

Who should consider this trial

Good fit: Ideal candidates are patients scheduled for elective open-heart surgeries such as CABG, valve repair or replacement, or aorta surgery.

Not a fit: Patients with current endocarditis or those for whom follow-up is not possible may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved identification of patients at risk for stroke, allowing for better preventative measures.

How similar studies have performed: Other studies have shown promise in identifying stroke risk through similar methodologies, but this specific approach is novel.
