Background: Obesity is a known predictor influencing access site complications. This study evaluated effect of body mass index (BMI) on procedural efficacy in transfemoral (TF) and transradial (TR) coronary angiography.
Methods: 10,020 coronary angiograms from University of South Dakota from 2011 to 2015 were analyzed. Normal body weight, underweight, overweight, obesity, and morbid obesity are defined as a BMI of <18.5, 18.5-24.9, 25-29.9, 30-39.9, and ≥40 kg/m2 respectively. Procedure efficacy, defined by total procedure time (PT), fluoroscopy time (FT) and contrast volume (Vol) was compared among TF and TR for each BMI group.
Results: Of the patients, 125 (1.3%) were underweight, 1,636 (16.3%) normal, 3,116 (31.1%) overweight, 4,046 (40.4%) obese and 1,097 (11.0%) morbidly obese. Most angiograms were done through TR (7,884, 77.3%), while fewer were done with TF (2,140, 23.6%). Figure A showed PT and FT for each BMI group. Analysis showed that PT (p<0.001) and FT (p<0.001) were statistically significantly lower for TR than for TF in patients with normal, overweight and obese BMI. Vol of TF in underweight, normal, overweight, and obese BMI were 66, 72, 81, 88, and 82 ml., respectively. Vol of TR in underweight, normal, overweight, and obese BMI were 60, 66, 73, 74, and 74 ml., respectively. Vol was statistically significantly lower in TR compared to TF in overweight (p=0.0015) and obese groups (p<0.001).
Conclusions: TR has superior procedural efficacy over TF access in normal, overweight and obese groups.
