Background: Abdominal obesity is an increasing public health problem and is associated with anumber of cardiovascular risk factors. The aim of this study was to determine the frequency ofabdominal obesity and associated risk factors in patients of various ethnic groups presenting withacute coronary syndrome. Methods: A total of 477 patients presenting with acute coronarysyndrome to the National Institute of Cardiovascular Diseases, Karachi were studied. The samplewas divided into 5 major ethnic groups, Muhajir, Punjabi, Sindhi, Pathan, Baluchi and Others. Waistcircumference of each patient was taken at the level of iliac crest and abdominal obesity was definedaccording to the International Diabetes Federation criteria of 2005 for South Asians as waistcircumference ≥ 90 Cm in males and ≥80 Cm in females. Patients were also assessed for diabetesmellitus, hypertension, smoking, low HDL and elevated triglycerides. Results: Out of 477 patients(355 males, 122 females), abdominal obesity was present in 318 (67%) patients, 62% of males and81% of females were obese. Abdominal obesity was 62% in Muhajir, 78% in Punjabi, 67% inSindhi, 68% in Pathan, 59% in Baluchi and 64% in others. Hypertension was present in 46%,Diabetes mellitus in 32%, Smoking in 33%, Low level of High density lipoprotein in 85.5% andraised triglycerides in 35% of patients. Conclusion: Abdominal obesity in Punjabi ethnic group ismore common as compared to other ethnic groups. Low level of high density lipoprotein is almostuniversally present in patients with acute coronary syndrome.Keywords: Abdominal obesity, Acute coronary syndrome, Waist circumference, Cardiovascular riskfactors
