Study of Acute Myocardial Infarction Admitted to ICCU with Special Reference to Arrhythmias

Abstract

BACKGROUND 
In this study, we wanted to evaluate patients with acute myocardial infarction admitted to 
ICCU with special reference to arrhythmias. 
METHODS 
This was a hospital based cross sectional study conducted among 50 patients who presented 
to ICCU, Narayana Medical College and Hospital, at Nellore, Andhra Pradesh, over a period 
of one year from March 2014 to February 2025 after obtaining clearance from Institutional 
Ethics Committee and written informed consent from the study participants. 
RESULTS 
Syncope is significantly dominant in NSTEMI. Left ventricular ejection fraction (LVEF) > 
50 % observed in 50 % cases of NSTEMI in comparison to 2.5 % in STEMI which is 
statistically significant. Statistically significant variables in STEMI included high mean TIMI 
risk score > 5 and depressed LVEF < 50 %. Statistically significant variables in NSTEMI 
included hypertension (HTN), syncope occurrence and LVEF > 50 %.
