Efficacy of atrial fibrillation predictors including MVP ECG risk score compared between single or bilateral internal...

Area of Science:

• Cardiovascular Surgery
• Cardiac Electrophysiology
• Medical Diagnostics

Background:

• Atrial fibrillation (AF) is a common post-coronary artery bypass surgery (CABG) complication.
• Primary prevention of AF is essential, though further research into predictive markers is needed.
• Internal Thoracic Artery (ITA) grafts are crucial for CABG, particularly for the Left Anterior Descending Artery (LAD), but graft choice for other vessels remains debated.

Purpose of the Study:

• To compare the incidence of arrhythmia, specifically AF, between patients undergoing CABG using single Internal Thoracic Artery (ITA) versus bilateral Internal Thoracic Artery (BITA) grafts.
• To identify potential predictors of postoperative AF in CABG patients.

Main Methods:

• A cohort of 84 isolated CABG patients was divided into two groups: single ITA and BITA.
• The occurrence of AF was recorded and compared between the two groups.
• Statistical analysis was performed to identify differences in AF incidence and associated factors.

Main Results:

• The overall incidence of AF was 15.5% (13 patients).
• AF was observed in 12.2% of the single ITA group and 18.6% of the BITA group, with no statistically significant difference.
• Diabetes Mellitus (DM) was significantly associated with AF (76.9% of AF patients had DM, p=0.011).
• Biphasic P wave, P wave duration, and MVP ECG score showed statistically significant differences.

Conclusions:

• The choice between single ITA and BITA grafts does not significantly alter the incidence of postoperative AF after CABG.
• Diabetes Mellitus, elevated blood glucose, and specific ECG findings are significant indicators of AF predisposition.
• The Morpholog-Voltage-P Wave ECG (MVP ECG) risk score is an effective marker for predicting AF in surgical patients.
