Population

124 patients with acute coronary syndromes (ACS)

Intervention

Non-dipole patterns at T-peak in resting magnetocardiography (MCG)

Comparator

Non-dipole patterns at T-peak on resting magnetocardiography predict long-term major adverse cardiac events in patients with acute coronary syndromes.

Abstract

The authors report on the association of non-dipole patterns at T-peak in resting magnetocardiography (MCG) and major adverse cardiac event (MACE), including composite of death from any cause, reinfarction, and percutaneous coronary intervention, during the follow-up period (mean 6.1 years) in 124 patients with acute coronary syndromes (ACS).1 In multivariate analysis, patients with non-dipole patterns at T-peak showed increased hazard ratios for MACE (p=0.02) and lower cumulative MACE-free survival than those with dipole patterns (p=0.02).
