Although the population distribution of CAC has been determined for several White populations, the distribution in ethnically admixed groups has not been well established. Distribution of calcium score. Al Helali S, Abid Hanif M, Alshugair N, Al Majed A, Belfageih A, Al Qahtani H, Al Dulikan S, Hamed H, Al Mousa A. Int J Cardiol Heart Vasc. Our results revealed that for a given CAC score, the ELSA-derived CAC percentile would be lower in men compared with the Multi-Ethnic Study of Atherosclerosis (MESA) and would be higher in women compared with MESA. CAC score in each coronary artery was equal to the sum of all lesions for that artery and the total CAC score was equal to the sum of the score of each artery. Categories chosen for histograms are evenly spaced on a logarithmic scale, corresponding to Ln(CAC) scores of <1, 12, 23, 34, 45, 56, 67, 78, and >8.

Our results revealed that for a given CAC score, the ELSA-derived CAC percentile would be lower in men compared with the Multi-Ethnic Study of Atherosclerosis (MESA) and would be higher in women compared with MESA. Your CAC score can indicate your risk of a heart attack. the observed age, gender, total cholesterol, HDL cholesterol, smoking status, A CAC score of 50, for example, may be unusually high for a 40-year-old woman without other CHD risk factors, but unusually low for a 70-year-old man with hypertension. PMC only for these four race/ethnicity categories and within this age range. you are 55 years old, but your arteries are more consistent with an arterial age of 65 years). After measuring her CAC score, however, there is a good chance (64%) that our recommendations would change. PMC We categorized patients according to age and sex, and examined histograms, quantile plots and box plots in each category to evaluate distributional normality.
