The gender-specific 99th percentile was also characteristic of some moderately sensitive . Am Heart J. the Multi-Ethnic Study of Atherosclerosis (MESA). WSB provided senior guidance in all aspects. Total CAC scores were assigned to a percentile according to age and gender. 1 In such patients, if . O'Malley PG, Jones DL, Feuerstein IM, Taylor AJ: Lack of correlation between psychological factors and subclinical coronary artery disease. There were significant differences in calcium by race, and these associations differed across age and gender. 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. No direct measurements of blood pressure, lipids or glucose were taken for the purposes of this study. This site needs JavaScript to work properly.

Blacks were lowest at the younger ages, and Chinese were lowest at the older ages. determining risk-based treatment strategies. The three study cohorts were convenient but very much unrelated, and despite the equal weighting to one third each may have introduced bias and thus not be readily generalizable; in particular, the 40% prevalence of hyperlipidemia, which is much higher than the US population of 30-45 years. 2020 Dec 17;14(2):76-79. doi: 10.17925/HI.2020.14.2.76. The analysis included 3616 individuals (54% female; mean age, 50 years). 10.1016/S0735-1097(98)00583-X. We also assumed that patients with high cholesterol had low-density lipoprotein (LDL) cholesterol levels of 130159 mg/dl and high density lipoprotein (HDL) cholesterol levels of 3544 mg/dl, whereas patients without high cholesterol had LDL cholesterol levels of 100129 mg/dl and HDL cholesterol levels of 4549 mg/dl (for men) or 5059 mg/dl (for women). but your arteries are more consistent with an arterial age of 65 years). 10.1016/S0002-9149(00)01403-X. On the other hand, if her CAC score were over 100 (17% chance), our estimate of her CHD risk would be approximately doubled (2531% if CAC score = 101400) or tripled (3451% if CAC score > 400). African-American, Hispanic, or Chinese. and transmitted securely. Distribution of Coronary Artery Calcium by Age, Sex, and Race Among Patients 30-45 Years Old. CV risk factors included hyperlipidemia in 41%, hypertension in 17%, smokers 10%, and diabetes 3%. Coronary artery calcium (CAC) has been demonstrated to be associated with the risk of coronary heart disease. PMC As expected, CAC prevalence and burden were steadily higher with increasing age, as well as increased in men and in White individuals.

We measured the independent cross-sectional associations between conventional cardiac risk factors and the CAC score among asymptomatic persons referred for non-contrast electron beam computed tomography. Only dichotomous indicators of such conditions were used. Learn more about the many factors that can increase your risk of developing CAD. New research suggests that a CAC score (which ranges from 0 to 1,000 or more) also can accurately predict a person's risk of dying over the following decade and a half.

We obtained risk factor-adjusted relative risk (RR) estimates from a meta-analysis [7] comparing the risk of a CHD event among persons with CAC scores of 1100 (RR = 2.1), 101400 (RR = 5.4) and <400 (RR = 10) to the risk in a person with a CAC score of zero. A spreadsheet that automates these calculations is attached.

All conventional CHD risk factors remained statistically significant predictors of the extent of coronary artery calcification (p < 0.001 for all predictors except high cholesterol at p = 0.004). Our models predicted, for example, that a 60-year-old non-smoking non-diabetic women with hypertension and high cholesterol would have a 47% chance of having a CAC score of zero, reducing her 10-year risk estimate from 15% (per Framingham) to 69%; if her score were over 100, however (a 17% chance), her risk estimate would be markedly higher (2551% in 10 years). 10.1016/S0002-9149(02)02636-X.
