RODRIGUEZ-GRANILLO, Gastón A. et al. Risk Factors and Extension of Ischemic Heart Disease Assessed by Non Invasive Coronary Angiography. Rev. argent. cardiol. [online]. 2008, vol.76, n.2, pp.112-117. ISSN 1850-3748.

Background Although several studies have well established the association between risk factors (RF) and cardiovascular events, the relationship between the total extension of coronary atherosclerosis and RF has not been clearly determined yet. Objective The aim of this study was to assess the relationship between traditional coronary risk factors with the presence and extension of coronary atherosclerosis using high-resolution multislice computed tomography (MSCT). Material and methods We conducted a monocentric and observational study on consecutive patients in sinus rhythm who underwent multislice computed tomography coronary angiography. The population was prospectively categorized in three groups according to the number of RF. Results One hundred and seventeen patients were included. Mean age was 58.5 ± 10.6 years, 81% were men and 19 suffered from diabetes. A positive association was observed between the number of RF and the prevalence of any lesion (p = 0,001), of significant lesions (p < 0.001), of multiple non significant lesions (p < 0.001) and of multiple significant lesions (p < 0.001). The number of lesions (1.9 ± 2.3 versus 4.3 ± 3.3 versus 6.6 ± 2.6, p < 0,001), and the calcium score [2.79 (0.0; 44.0) versus 64.0 (0.0; 273.2) versus 539.0 (74.0; 1,405.9), p = 0.001] were significantly greater in patients with multiple RF. Several RF were individually associated with the presence of lesions. Age, diabetes, hypercholesterolemia,hypertension, a history of previous myocardial infarction and smoking habits were related to the presence of atherosclerosis, either by the evidence of a greater prevalence of lesions, of greater total number of lesions ad/or higher calcium scores. Conclusions This study found a significant relationship between the number of risk factors, as well as several risk factors per se, and the extension of coronary atherosclerosis assessed by multislice computed tomography coronary angiography.
