Background: Prevalence of the metabolic syndrome (MetS) is associated with increased risk of cardiovascular disease and diabetes. Present study aimed to assess the frequency distribution of various components of metabolic syndrome in patients younger than 50 years of age. Materials and method: The study group consisted of 100 patients less than 50 years of age admitted at Rajindra Hospital with acute coronary disease. Results: Most common age group was 45-50 years in both males and females, with 66% patients belongs to this age group. 37 patients of ACS with MS, most common component in males was raised blood pressure (SBP and DBP), in females most common component was impaired fasting plasma glucose (FPG). Waist circumference was statistically significantly raised in patients of ACS with MetS as compared to patients of ACS without MetS. Systolic blood pressure (SBP) was statistically significantly raised in patients of ACS with MS as compared to patients of ACS without MS. Systolic blood pressure (SBP) was statistically significantly raised in patients of ACS with MetS as compared to patients of ACS without MetS. Fasting plasma glucose (FPG) Serum triglycerides(TGc) and Serum high density lipoproteins (LDL) was statistically significantly raised in patients of ACS Conclusion: All the five components of metabolic syndrome i.e. waist circumference, systolic blood pressure, fasting plasma glucose, serum triglycerides, serum high density lipoproteins were significantly associated with patients of acute coronary syndrome with metabolic syndrome as compared to patients of acute coronary syndrome without metabolic syndrome.
