title: Differences Among Body Mass Index (BMI) Groups in Patients Undergoing First Elective Percutaneous Coronary Intervention.
abstract: OBJECTIVE
  Body Mass Index (BMI) is known to be an independent risk factor for hypertension, type 2 diabetes mellitus, dyslipidemia and various cardiovascular diseases. Our aim was to investigate the differences among BMI groups in patients undergoing first elective PCI.
  
  
  METHODS
  781 consecutive patients who underwent their first-time elective PCI from September 2011 to December 2013 in the Department of Cardiology were enrolled in the study. The patients with BMI < 18.5 kg/m(2) or > 50 kg/m(2) and those who had previously undergone revascularization were excluded from the study. Patients were categorized according to their BMI groups. BMI 18.5 - 24.9 kg/m(2) normal group, 25 - 29.9 kg/m(2) overweight group and > 30 kg/m(2) obese group. We studied the demographic, angiographic, and interventional differences between BMI groups.
  
  
  RESULTS
  Compared with normal weight individuals, those obese were younger (61.9 ±10.34 vs. 58.41 ± 8.01 p = 0.0006), had higher prevalence of diabetes mellitus (46.4% vs. 26.6% p = 0.0001), dyslipidemia (77.5% vs. 65.4% p=0.0134) and hypertension (1.3% vs. 81.3% p=0.0067). There was a greater use of calcium channel blockers (CCBs) and Angiotensin Enzyme Inhibitors (ACEIs)/Angiotensin Receptor Blockers (ARBs) in obese individuals but it was not statistically significant. Obese individuals were associated with higher risk anatomy (3-Vessel CAD or LM) compared to normal individuals but not statistically significant (18.8% vs. 14.2% p=0.25). Obese patients were associated with a higher length of stents/person used (36.7 ± 22.02 vs. 31.7 ± 17.48 p=0.016) and also a larger diameter of stents/person used (3.14 ± 0.4 vs. 2.98 ± 0.33 p=0.0001) compared to normal individuals.
  
  
  CONCLUSIONS
  Patients with a higher BMI are younger and have diabetes mellitus, hypertension and dyslipidemia more frequently. Patients with a higher BMI have a higher length and larger diameter of stents/person used, probably related to a more extensive coronary artery disease.
