Prevalence of metabolic syndrome and its clinical and angiographic profile in patients with naive acute coronary syndrome

Objective: The objective of the study is to evaluate the prevalence of metabolic syndrome (MS) and its clinical and angiographic profile in patients with naive acute coronary syndrome (ACS). Furthermore, this study tried to evaluate the severity of coronary artery disease in patients with and without MS. Methods: This was a single-center, cross-sectional study which prospectively enrolled 500 patients with naive ACS during the period from January 2017 to December 2018 at a tertiary care center in India. They were divided into two groups according to the presence and absence of MS based on revised NCEP ATP III guidelines. The ACS was defined based on the Joint Committee of the American College of Cardiology. After clinical evaluation and investigations, the prevalence of MS in ACS patients was calculated. Results: Prevalence of MS in this study was 46.2% and was more frequent in males (81%) compared to females (19%). Maximum number of patients with MS were between the age group of 40–59 years (55%). Prevalence of diabetes (56.7%), hypertension (58.0%), and smoking (45.88%) were significantly higher in patients with MS (P < 0.001). Most prevalent components of MS were low high-density lipoprotein (HDL) levels, increased blood pressure, fasting blood sugar, and triglyceride levels (P < 0.001). Conclusion: Prevalence of MS was high in patients with ACS and was more often after the age of 40 years and most commonly seen in males. Low HDL levels, increased blood pressure, and blood sugar were most prevalent components in the criteria for MS. Patients with MS tend to have more complex coronary lesions.
