Post Cardiac Surgery Arrest Mortality in ICU among 3343 Patients, a Six Year Study

Introduction: The prevalence of post cardiac surgery arrest in adult patients is 0.7-2.9%. The main causes of cardiac arrest following cardiac surgery are ventricular fibrillation, tamponade and major bleeding. The aim of this study is to determine the mortality rate of post cardiac surgery arrest and its causes.
Method: A total of 3342 patients that have undergone cardiac surgery in Sina hospital, Isfahan, Iran between 2009-2014 were studied. Those who experienced cardiac arrest in ICU were included. Those subjects who were discharged and had arrest were excluded. The data were obtained via Sina’s electronic database which is based on European association of cardiac surgery database. The statistical analyses were carried out by SPSS 16.0. Data were shown as frequency (%). For comparing qualitative variables between groups Chi square test was used. Logistic regression was used to determine single and multiple effects. The variables are sex, age, and procedure group, cause of cardiac arrest and rate of mortality.
