Coronary Artery Disease;

Objectives: To establish or refute any association between high Body Mass Index (BMI) and Coronary Artery Disease in South Punjab area of Pakistan. Background: Ischemic heart disease has a strong relation with high Body Mass Index (BMI). But still uncertainty persists about the association that exists between overweight (BMI 25-29.9 kg/m2) or obese patients (BMI >30 kg/m2). Design: Observational, Cross Sectional Study. Setting: Cardiac cath lab department of Multan Institute of cardiology Multan. Duration of Study: Six month tenure extending between January 2017 to June 2017. Methods: The study was conducted in cardiac cath lab department of Multan Institute of cardiology, Multan. Total of Four hundred and seventy eight patients (478) over a period of two months were included in the study. All patients were having a coronary angiography due to a medical indication. Their BMI was calculated by using standard formula. Results: Out of 478 patients 335 (70.1%) patients were having optimal weight. 123 (25.7%) were overweight, 12 (2.5%) were mildly obese, 8 (1.7%) were severely obese patients. Optimal weight patients had 12.5% normal coronary angiogram, 26.3 % had single vessel CAD, 20% had two vessel disease and 41.2% had severe triple vessel disease. Over weight patients had 17.9% normal coronary angiograms, single vessel CAD was seen in 26.8% patients, 21.9% patients had two vessel disease and 33.3% had severe triple vessel CAD. Mildly obese patients had 8.3% normal coronary angiograms, 50% had single vessel CAD, 25% had two vessel disease, and 16.7% had severe Triple vessel disease. Among severe obese patients 12.5% had normal coronary angiography, 25% had single vessel disease, 50% had two vessel disease, and 12.5% had severe triple vessel disease. Conclusion: Patients undergoing Coronary Angiogram in the region of south Punjab did not show any significant relationship between severity of CAD (Severe two vessels & severe Triple vessel disease) and BMI.
