Background: Coronary heart disease is a major cause of mortality and morbidity worldwide. In this study we looked at the demographics, risk factors, presenting symptoms and in-hospital outcome in patient less than 45 years of age and compare with old age patients 45 years or more.
Objective: To evaluate the differential features of acute myocardial infarction in patients younger than 45 yrs old compared to older patients (45 yrs or more).
Methods: This was a Cross-sectional prospective study conducted on patient admitted in Intensive Care Unit, Department of Cardiology, J.A. Group of Hospitals, Gwalior (M.P.) between December 2016 to September 2018.Patients divided into two group by age those who were aged less than 45 years(Group-A) and those who 45 years or more(Group-B) each group includes 50 patient.
Results: In Group-A 8% patient were female and mean age was 36.98 years, in Group-B 20% were female and mean age was 60.82 years, in group-A 94% patients were presented with chest pain while 76% in group-B. In Group-A 92% had STEMI out of which 47.8% present with AWMI and 26.08% with IWMI and 8% had NSTEMI, in group-B 76% had STEMI out of which 42.10% present with AWMI and 31.57% with IWMI and 24% had NSTEMI. In group A 16% patients were hypertensive,8% diabetic,70% current smokers,50% overweight and 64% dislipidemic in group B 40% patients were hypertensive,14% diabetic,22% current smokers,22% overweight and 32% dislipidemic respectively. The overall mortality 2% in group A and 12% in group B
Conclusion: Myocardial infarction in male was more common and Most common symptoms were chest pain in both age groups Most common clinical presentation was in form of STEMI and Anterior MI was the commonest. In our study, current smoking, dyslipidemia and overweight found to be significant risk factor for Myocardial Infarction in young but in Group B HTN was the most common risk factor followed by dyslipidemia. This knowledge of the different profiles of risk factors and extent of CAD in two different age groups of IHD patients in Gwalior region will help us planning for both preventive and curative treatment strategy in future.
