INTRODUCTION: The coronary calcium's score and the quantification of media intima thickness are developing methods used in atherosclerosis diagnosis. OBJECTIVE: To assess the coronary calcium score relation to classic cardiovascular risk factors and the carotid media intima thickness. METHODS: Sample included 70 patients with suspicion of ischemic heart disease. In all of them the coronary calcium was quantified by 64 scans tomography and the media intima thickness by medias of ultrasound (US). Using continuously the dependent variable (coronary calcium score) we made a simple linear regression to obtain the regression coefficients (ß). The statistic significance level (a) used was of 95 % (value p < 0,05 as statistically significant). RESULTS: Calcium score was higher in male sex subjects increasing linearly and annually with age in 11.4 UA. The correlation coefficient between calcium score and age was of 0.36 statistically significant (p = 0,002). The 88,9% of patients with a media intima thickness greater than 1mm had some degree of coronary calcification, was twice greater than those with a media intima thickness less than 1mm. Correlation value (r) with carotid media intima thickness was of 0.24 (p = 0.04). CONCLUSIONS: Age, male sex and increase of carotid media intima thickness, is significantly related to presence and quantity of coronary calcification.
