Key result
Electrocardiographic preexcitation was associated with higher hazards of atrial fibrillation (HR 3.12; 95% CI 2.07-4.70) and heart failure (HR 2.11; 95% CI 1.27-3.50) in a primary care population.

May prompt closer AF/HF monitoring in primary care preexcitation; extends observational data but leaves causal effects open to trials.

Does electrocardiographic preexcitation increase the risk of cardiovascular morbidity and mortality in a primary care population?
Hazard Ratio: 3.12 (95% CI 2.07–4.7)
Electrocardiographic preexcitation in a primary care population is associated with significantly higher risks of atrial fibrillation and heart failure, and increased mortality in patients aged 65 or older.
Skov et al. (2017) conducted a cohort in Electrocardiographic preexcitation (n=328,638). Electrocardiographic preexcitation vs. Remainder of the population was evaluated on Atrial fibrillation (HR 3.12, 95% CI 2.07-4.70). Electrocardiographic preexcitation was associated with higher hazards of atrial fibrillation (HR 3.12; 95% CI 2.07-4.70) and heart failure (HR 2.11; 95% CI 1.27-3.50) in a primary care population.
