BCHE and coronary artery disorder: Previous studies have suggested a causative role of BChE in the development of CAD and a predictive value of BChE for cardiac mortality.[3, 6–7] We have recently demonstrated that high BChE activity represents a strong and independent predictive value for long-term outcome in patients with proven CAD and that patients within the lowest tertile of BChE activity had a significantly higher rate of cardiovascular mortality than patients within the remaining tertiles.[4] However, there are yet no data on the age-dependent prognostic value of BChE in younger patients.
