Abstract

|
Purpose: Right ventricular (RV) involvement during acute inferior myocardial infarction (MI) is associated with
increased early mortality and morbidity. However, little is known concerning mortality and morbidity after right ventricular
myocardial infarction (RVMI) during percutaneous coronary intervention (PCI).
Methods: This retrospective study was performed in a university training hospital. Patients with inferior MI (n=94) who presented to the emergency department between November 2005 and October 2007 were included. We
examined the incidence of death, mechanical complications and electrical complications in patients with (n=29) and
without (n=65) RV myocardial involvement. RV involvement was assessed by ST-Segment elevation ≥0.1 mV in lead
V4R. PCI was performed in all patients.
Results: In-hospital mortality was 3.4% in RVMI compared with 3.1% in non-RVMI (p=1.00). There was no significant difference in the incidence of mechanical complications and electrical complications between patients with and without RVMI.
Conclusion: Patients who have inferior MI with RV myocardial involvement are not at increased risk of death,
mechanical complications and electrical complications.
