Abstract:
Objective To explore the clinical and coronary angiographic characteristics in acute myocardial infarction (AMI) patients with new-onset atrial ifbrillation in early or later stages. Methods From Jun. 2010 to Jun. 2013, 1358 cases of AMI were hospitalized in which 88 were proved to have AMI complicated with new-onset atrial ifbrillation. Eligible patients were divided into early onset group (group1, n=40 cases) and the later onset group (group2, n=48 cases) according to the occurrence of atrial ifbrillation within or after 24 hours of admission. The clinical characteristics and the pathological changes of coronary arteries of the two groups were compared respectively. Results The incidence of inferior wall AMI was signiifcantly higher in group 1. The incidence of anterior wall AMI was signiifcantly higher in group 2 (P<0.05). The incidence of congestive heart failure, the incidence of three-vessel lesions and the in-hospital mortality in group 2 were higher than which in group 1 (P < 0.05). Conclusions The new-onset atrial ifbrillation in different stages may be regarded as a useful indicator for evaluating the clinical characteristic and the infarct-related coronary artery lesions and prognosis of patients with AMI.
