Bowel Preparation and Subsequent Colonoscopy Is Associated with the Risk of Atrial Fibrillation: A Population-Based...

Area of Science:

• Cardiology
• Gastroenterology
• Epidemiology

Background:

• Atrial fibrillation (AF) is a common arrhythmia.
• Colonoscopy is a routine diagnostic procedure.
• The potential cardiac risks associated with bowel preparation and colonoscopy are not fully understood.

Purpose of the Study:

• To investigate the association between bowel preparation, colonoscopy, and the risk of new-onset atrial fibrillation (AF).

Main Methods:

• Population-based case-crossover study design.
• Included patients who developed new-onset AF after colonoscopy.
• Matched hazard periods with four control periods for each patient.
• Analyzed data from 84 AF patients meeting inclusion criteria.

Main Results:

• A significant association was found between bowel preparation/colonoscopy and AF occurrence across all analyzed time windows (1-12 weeks).
• The proportion of patients undergoing bowel preparation and colonoscopy was significantly higher during the hazard period compared to control periods.
• Odds ratios (ORs) for AF ranged from 3.11 (1 week) to 2.61 (12 weeks), indicating increased risk.

Conclusions:

• Bowel preparation and colonoscopy are associated with an increased risk of atrial fibrillation.
• This risk is particularly relevant for elderly patients with a history of hypertension.
• Medical professionals should exercise caution when performing these procedures in at-risk populations.
