We examined body mass index (BMI) in kilograms divided by height in meters squared in 842 patients who underwent coronary angiography for suspected coronary artery disease (CAD) in a 2-month period in 2000 at Baylor University Medical Center. Comparison of the BMI in the 624 patients in whom > or =1 coronary artery was narrowed >50% in diameter to the BMI in the 218 patients with absent or lesser degrees of coronary narrowing disclosed the following: the BMI was >30 (obese) in 209 (33%) versus 92 (42%) patients (p 0.008): 26 to 30 (overweight but not obese) in 233 (37%) versus 80 patients (37%) (p = NS), and BMI < or =25 (ideal) in 182 (29%) versus 46 (21%) patients (p 0.01). Compared with the patients > or =65 years of age, the patients <65 years of age in both groups had a higher frequency of obesity and a lower frequency of ideal body weight. In conclusion, patients with coronary narrowing >50% in diameter were less likely to be obese and more likely to be at ideal body weight than the group of patients with absent or lesser degrees coronary narrowing by angiogram.
