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.
2000年，在两个月的时间里，我们在贝勒大学医学中心对842名因疑似冠状动脉疾病（CAD）接受冠状动脉造影的患者进行了体重指数（BMI）的检查，BMI的计算方法是体重（千克）除以身高（米）的平方。将624名直径≥1条冠状动脉狭窄>50%的患者的BMI与218名冠状动脉狭窄程度较轻或无狭窄的患者的BMI进行比较，结果如下：BMI>30（肥胖）的患者中，前者有209名（33%），后者有92名（42%）（p = 0.008）；BMI在26至30之间（超重但不肥胖）的患者中，前者有233名（37%），后者有80名（37%）（p =无显著差异）；BMI≤25（理想体重）的患者中，前者有182名（29%），后者有46名（21%）（p = 0.01）。与年龄≥65岁的患者相比，两组中年龄<65岁的患者肥胖发生率更高，理想体重发生率更低。总之，与冠状动脉造影显示冠状动脉狭窄程度较轻或无狭窄的患者组相比，直径狭窄>50%的冠状动脉狭窄患者肥胖的可能性较小，处于理想体重的可能性较大。
