Comparison of the findings of present study with other studies from South East Asia.

Author Year	Type of Study	Size of Population Studied	Findings of this Study	Findings of Our Study
James C et al., [35] 2013	Cross-sectional Study	496	Irrespective of gender, diabetes and dyslipidemia were found to be the major risk factors owing to CAD.	Dyslipidemia and HTN were found to be the top two contributing factors to CAD.
Khan MA et al., [36] 2012	Retrospective Study	3025	The frequency of CAD showed a significant increase in the local population, more so in women. There was increasing trend of CAD in the younger age group over the time span.	The majority of the patients enrolled in our study were males and of the older age bracket, however we did not investigate this trend over the years.
Butt Z et al., [3] 2010	Cross-sectional Study	100	Females have a higher prevalence of diabetes and HTN and less prevalence of smoking as compared to males.	Consistent with the findings of this study.
Jayachandra S et al [4] 2014	Cross-sectional Study	190	HTN and smoking were the most common risk factors in young patients. Along with HTN, diabetes and CKD were found in elderly patients.	Diabetes and dyslipidemia were more frequent risk factors in elderly patients, whereas smoking, HTN and a family history of MI or CAD were similar between the two age groups.
Saleheen D et al., [14] 2004	Cross-sectional Study	976	Majority of the patients admitted were males and older than 45 years of age. Young AMI patients had a positive history of HTN, family history of CAD, high cholesterol, high LDL and high triglycerides as compared to older patients.	Majority of the patients enrolled were males and in the older age bracket. HTN and a positive family history of CAD as risk factors were common between the two age groups. High cholesterol levels were more prevalent in the older age bracket.
Goel PK et al [22] 2002	Retrospective Study	2656	In north Indians, CAD occurs at much lower levels of total cholesterol and LDL. Hypertriglyceridemia is widely prevalent in this population. Smoking and family history of CAD were most commonly associated risk factors in younger patients.	Dyslipidemia and HTN were most commonly associated risk factors in younger patients
Naqvi SM et al., [23] 2015	Prospective Observational Study	162	Mean Hb levels decreased as the severity of CAD increased, however this association was not statistically significant	Mean Hb levels and red cell indices were higher in males and those in the young age bracket. We did not see the correlation of Hb with the severity of the disease.

AMI: acute myocardial infarction; CAD:coronary artery disease; CKD: chronic kidney disease; Hb: hemoglobin; HTN: hypertension; LDL: low density lipoprotein; MI: myocardial infarction
