Clinical Outcomes of Post Cardiac Arrest Survival Patients Receiving Automatic Implantable Cardioverter Defibrillator (AICD) Implantation at Srinagarind Hospital and Queen Sirikit Heart Center of the Northeast Khon Kaen University

Abstract

Background and Objective: Sudden cardiac death is a major health problem. The implantation of an Automatic Implantable Cardioverter Defibrillator (AICD) is an accepted standard treatment for post sudden cardiac death survival patients with evidence of structural heart disease or primary cardiac channelopathy. This study aimed to  determine the clinical outcomes in post cardiac arrest survival patients receiving AICD treatment at Srinagarind Hospital and the Queen Sirikit Heart Center of The Northeast , Khon Kaen University

Methods: This study was a retrospective observational study in post cardiac arrest survival patients receiving AICD treatment  during January 2007- December 2010.

Results: There were 79 patients (67 men (84.8%) and 12 women (15.2%)) were recruited for the analysis, their average age were 49.9±12.8 years. Brugada Syndrome (BrS) , coronary artery disease(CAD) and dilated cardiomyopathy (DCM) were diagnosed in 35 patients (44.3%), 15 patients (19.0%) and 14 patients (17.7%), respectively. During the one year of follow-up period, 2 patients (2.5%) died. Appropriated AICD treatment occurred in 25 patients (32%), AICD was removed in 1 patient (1.3%) due to infection and inappropriate AICD shock was occurred in 9 patients (11.4%).

Conclusion: AICD treatment in post cardiac arrest survivals patients were effective to prevent recurrent cardiac arrest.  Appropriate AICD treatment  were 2.78 times more frequent than inappropriate shock.  Overall complication including inappropriate shock and infection after AICD implantation were low.
