房颤是急性心肌梗死常见并发症,并与患者死亡危险增加相关。迄今为止,这类患者与房颤相关的病死率过多增加的具体原因尚未阐明。一些研究证实,房颤易于诱发室性心律失常,并认为这可能使心源性猝死的危险增加。丹麦哥本哈根Bispebjerg 大学医院的Pedersen及其同事对急性心肌梗死伴房颤或房扑患者的死亡方式进行了密切观察,并将观察结果发表在11月的European Heart Journal杂志上。研究人员对“群多普利治疗心脏功能评估研究”注册的存活急性心肌 Atrial fibrillation is a common complication of acute myocardial infarction and is associated with an increased risk of death in patients. To date, the exact cause of the excess mortality associated with atrial fibrillation has not yet been elucidated. Some studies have confirmed that atrial fibrillation is likely to induce ventricular arrhythmias, and that this may increase the risk of sudden cardiac death. Pedersen and colleagues at Bispebjerg University Hospital in Copenhagen, Denmark, closely observed the death pattern of patients with acute myocardial infarction with atrial fibrillation or atrial flutter and published the findings in the November issue of the European Heart Journal. Researchers on the “trandolapril cardiac function assessment study” registered survivors of acute myocardial
