Early Arrhythmias in Myocardial Infarction Patients within the First 24 Hours:A Study in a Tertiary Care Hospital, Bareilly (Code-T0311)

Introduction: Cardiovascular diseases remain a leading cause of morbidity and mortality
worldwide, with myocardial infarction (MI) being a primary contributor. A significant
proportion of sudden cardiac deaths following MI are due to arrhythmias, which frequently
develop within the first 24 hours. Identifying high-risk patients and understanding the patterns of
arrhythmias can improve early intervention strategies and patient outcomes.
Aims and Objectives
Aim:
To study the types of arrhythmias in patients in first 24 hours following myocardial infarction.
Objectives:
To study the effect of age, gender, lifestyle, co-morbidities in development of arrhythmias after
myocardial infarction.
To study the various prognostic factors related to arrhythmias in outcomes of patients with
myocardial infarction.
Methods:A prospective observational study was conducted at Rajshree Medical Research
Institute, Bareilly. A total of 100 MI patients were included, and continuous electrocardiographic
(ECG) monitoring was performed to detect arrhythmias. Clinical parameters such as age,
comorbidities, and biochemical markers (Troponin I, CPK-MB) were analyzed. Statistical
analysis was conducted to determine correlations between risk factors and arrhythmia
occurrence.
Results: Arrhythmias were detected in a significant proportion of patients, with ventricular
tachycardia and atrial fibrillation being the most common. Advanced age, hypertension, and
diabetes were strong predictors of arrhythmia development. Patients with arrhythmias had a
higher rate of adverse outcomes, including prolonged hospital stay and increased mortality.
Conclusion: Early identification and management of arrhythmias in MI patients are crucial for
reducing complications. Continuous ECG monitoring and risk stratification should be standard
practice in tertiary care settings.
