This study includes male subjects age 45 to 70, who have sustained a traumatic Spinal Cord Injury (SCI) at least 10 years prior. Subjects will be interviewed for demographic data, including heart disease risk factors. A blood test for cholesterol levels will be drawn. A CT scan of arteries of the heart will be performed to determine the presence of coronary calcium, a marker of subclinical Coronary Heart Disease. Scoring of Coronary Calcium or Coronary Calcium Score (CCS) is automated by the CT scanner. Each subject's Framingham Risk Score will be calculated; This is an individuals 10 year risk of having a Coronary Heart Disease event (significant symptoms). In addition, it will be determined if subjects are being treated for diagnosed dyslipidemia (high cholesterol) according to the National Cholesterol Educational Program (NCEP) guidelines.

The proposed pilot study aims to better understand the problem of Coronary Heart Disease in individuals with Spinal Cord Injury, specifically CCS in SCI, when compared to the general population.
