Angiographic Findings in Survivors of Sudden Cardiac Arrest

Abstract

Background: Sudden cardiac arrest is a fatal complication and survivors of these definitively require angiographic workup for underlying etiologies. Objective: To determine the severity of coronary artery disease and frequency of coronary arteries involved in survivors of sudden cardiac arrest. Methodology: Study Design: Descriptive study with consecutive sampling. Setting: Department of Cardiology, Sheikh Zayed Hospital, Rahim Yar Khan. Duration: August, 2017 to March, 2018. The survivors of sudden cardiac arrest of either sex, with age range of 30 to 60 years, were included. These then underwent coronary angiography and stenosis more than 50% was taken as significant and number of vessels involved were noted. Results: There were 96 cases of survivors of sudden cardiac arrest; 67 (69.79%) males, and mean age of 49.27±5.56 years. Severe coronary artery disease (CAD) was seen in 59 (61.46%) of cases. Severe CAD was significantly high in male, 46 (68.66%) cases (p=0.04). There was no statistical difference in age group with p= 0.33. Severe CAD was more in cases having raised BMI and DM (p=0.51 and 0.18). It was significantly high in cases with hypertension 29 (82.85%) (p= 0.001) and those with dyslipidemia affecting 29 (78.38%) cases with p= 0.009. Out of the cases detected with severe CAD, double CVD was the most common 26 (27.08%) of cases. Conclusion: Coronary artery disease is one of the most common etiology in survivors of sudden cardiac arrest and it is significantly high in male gender and those suffering from hypertension and dyslipidemia.
