Advanced Metallic Stents and Their Efficiency in Complicated Myocardial Infarction Treatment

Complete atrio-ventricular block (CAVB) develops in more than 5% of patients with myocardial infarction. Before the primary percutaneous coronary intervention (PCI) era, this condition was associated with poorer outcomes compared to those without complete AVB. Limited data are available regarding the outcome of these patients after primary PCI. In order to assess the outcome of patients with acute ST segment elevation myocardial infarction (STEMI) complicated with CAVB and treated with primary PCI a retrospective analysis of recordings of patients (pts) hospitalized with acute STEMI between 5.02.2009-30.05.2013 and treated with primary PCI was performed. The pts were divided in two subgroups: CAVB group and non-CAVB group, according to the presence or absence of CAVB at the time of PCI. Among 868 pts 57 pts. (6.5%) presented CAVB. The patients with CAVB were older (mean age 68.0 + 16.63 vs. 65.4 + 11.36 years, p < 0.0000001, were female in greater proportion (31.5% vs. 16%, p = 0.043), had more diabetes m...
