Clinical Profile and Outcome of Acute Myocardial Infarction among Young Adults at a Tertiary Care Centre in Manipur, India: A Cohort Study

Abstract

Introduction: The incidence of Acute Myocardial Infarction (AMI) is rising in young adults. Timely control of cardiovascular risk factors is important to prevent the increasing incidence of AMI in young adults. Aim: To analyse the clinical profile, risk factors, and outcomes of AMI among the young adult population in Manipur, India. Materials and Methods: A hospital-based cohort study was conducted in a tertiary care centre at Department of Medicine, Regional Institute of Medical Sciences, Imphal, Manipur, India from January 1, 2021, to December 31, 2022, among patients aged 45 years or younger attending the medicine Outpatient Department (OPD), admitted to the Intensive Care Unit (ICU) and Intensive Coronary Care Unit (ICCU) with the first attack of AMI. Cases involving pregnancy, known cases of pericarditis, and Congenital Heart Disease (CHD) were excluded. Data were collected using a performa regarding demographic profile, clinical presentation, risk factors, and treatment outcomes. The data were analysed using Statistical Package for Social Sciences (SPSS) 21.0 and expressed as descriptive statistics. Results: A total of 39 cases were reported with a mean age of 40.2±4.6 years, with a male-to-female ratio of 9:1. The majority of cases presented with chest pain (74.3%), followed by shortness of breath (40%), nausea (13%), and collapse (10%). 75% of cases presented with multiple clinical features. The most common risk factors in young adults were smoking (84.6%), alcohol consumption (56.4%), family history of heart disease (25.6%), hypertension (20.5%), substance abuse (20.5%), diabetes (17.9%), and dyslipidemia (25.6%). Cases showed elevated cardiac enzymes - Creatine Kinase-Myocardial Band (CK-MB) (92.3%) and Troponin I (94.9%). Electrocardiogram (ECG) changes revealed ST segment elevation MI (89.7%). Only one case resulted in death during the hospital stay. Conclusion: The incidence of AMI among young adult populations is increasing, emphasising the need to raise awareness regarding cardiovascular risk factors and lifestyle modifications. However, the cases have shown good clinical outcomes among young adults with the disease.
