Coronary Artery Calcification Score and Risk Factors for Coronary Artery Disease in Persons With Spinal Cord Injury (CAC)
Although conventional risk factors for coronary heart disease (CHD) have been identified and routinely used to determine risk for CHD in the general population, a systematic approach to determine population-specific risk for CHD has not been performed prospectively in those with SCI. CHD is a leading cause of death in spinal cord injury, occurring at younger ages than in the able-bodied population. Conventional risk factors for CHD are high serum concentrations of low-density lipoprotein (LDL), low serum concentrations of high-density lipoprotein (HDL), diabetes mellitus (DM), positive smoking history, and positive family history of premature CHD.
Coronary Artery calcification (CAC) is a commonly occurring phenomenon that does not necessarily indicate significant obstructive disease. Studies have shown that a strong association exists between coronary calcification and coronary heart disease. The purpose of this study is to compare the CAC scores in persons with SCI with a historical control group of able-bodied persons from a national data base who will be matched for conventional risk factors for coronary artery disease (CAD) and to determine the relationship between CAC scores and conventional and emerging risk factors for CAD. Additionally, postprandial lipemic (elevated levels of lipids following ingestion of food) responses among individuals with SCI and control subjects will be compared, as well as the response of inflammatory markers following a high fat meal. Participants will only be tested once for these parameters.

|Official Title:||Coronary Artery Calcification (CAC) Score and Risk Factors for Coronary Artery Disease in Persons With Spinal Cord Injury(SCI)|
- Coronary heart disease risk factors [ Time Frame: Testing will be performed at day 1 for all parameters ] [ Designated as safety issue: No ]The relationship of coronary artery calcification (CAC) with conventional risk factors (cigarette smoking, hypertension, low high density lipoprotein(HDL) cholesterol, diabetes) and nonconventional risk factors (abdominal fat, inflammatory biomarkers, arterial stiffness, intima media thickness of carotid artery) is being tested to determine the prevalence and severity of coronary artery calcification (CAC) score of SCI individuals with age, gender and ethnically matched controls.
- Postprandial lipemic response to a high fat meal(1.3 gm/kg body weight) [ Time Frame: Single fat meal challenge test will be performed at day 1. ] [ Designated as safety issue: No ]To determine the postprandial lipemic response to fat load in persons with SCI and to correlate these parameters to other risk factors for CAD and CAC score.
