Only two provide actual post-test risk estimates for specific clinical situations [23, 24]. 1,2 Each subject underwent electron beam computed tomography scanning with an Imatron C-100 or C-150 scanner (Imatron, South San Francisco, California) after giving written informed consent. N Engl J Med. Schmermund A, Erbel R, Silber S: Age and gender distribution of coronary artery calcium measured by four-slice computed tomography in 2,030 persons with no symptoms of coronary artery disease. By integrating this information with previously published relative risk estimates (see Additional File 1), we estimate her 10-year CHD risk to be as low as 6% (if her CAC score is 0), or as high as 51% (if her CAC score is >400). Am J Cardiol. Our approach takes into account the pre-test coronary risk, the expected distribution of CAC scores adjusted for all conventional CHD risk factors, and summary adjusted relative risks from a recent meta-analysis, and provides clinically relevant post-test risk estimates that may be directly useful to primary care physicians, cardiologists and patients as they decide whether or not to take medications for primary prevention of CHD. Am J Cardiol. We estimated these probabilities, using models containing the 10-year risk estimate as the only predictor, for a range of 10-year risk estimates. Methods: The Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) is a prospective cohort study designed to investigate subclinical cardiovascular disease in 6 different centers of Brazil. JAT and MP helped design and interpret the analysis. you are 55 years old, but your arteries are more consistent with an arterial age of 65 years). Subjects with a history of CHD or complaining currently of any chest pain were excluded, as were subjects for whom CHD risk factor data were incomplete or missing. The gender-specific 99th percentile was also characteristic of some moderately sensitive . The analysis was repeated using more conservative estimates from the same paper: RR = 1.7 (for CAC 1100), RR = 3.0 (for CAC 101400), and RR = 4.3 (for CAC>400). Although the population distribution of CAC has been determined for several White populations, the distribution in ethnically admixed groups has not been well established. The probability that her treatment plan would be altered by measurement of her CAC score, therefore, is approximately 64% (the probability that her score is either 0 or >100 = 47% + 17%), indicating likely usefulness of the test in this situation. 1999, 33: 453-62. Clinical Topics: Cardiovascular Care Team, Congenital Heart Disease and Pediatric Cardiology, Diabetes and Cardiometabolic Disease, Dyslipidemia, Noninvasive Imaging, Prevention, Atherosclerotic Disease (CAD/PAD), CHD and Pediatrics and Arrhythmias, CHD and Pediatrics and Imaging, CHD and Pediatrics and Prevention, CHD and Pediatrics and Quality Improvement, Computed Tomography, Nuclear Imaging, Hypertension, Keywords: Atherosclerosis, Coronary Artery Disease, Diabetes Mellitus, Dyslipidemias, Hyperlipidemias, Hypertension, Middle Aged, Obesity, Plaque, Atherosclerotic, Primary Prevention, Risk Assessment, Risk Factors, Smokers, Tomography, X-Ray Computed, Vascular Calcification, Young Adult. Mitchell TL, Pippin JJ, Devers SM, Kimball TE, Cannaday JJ, Gibbons LW, et al: Age- and sex-based nomograms from coronary artery calcium scores as determined by electron beam computed tomography. Age and sex were strong predictors of the presence of CAC in logistic regression models (Table 2).

Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available. 2003, 289: 1278-87. The .gov means its official. AB - Background: Coronary artery calcium (CAC) has been demonstrated to independently predict the risk of cardiovascular events and all-cause mortality, especially among White populations. Pereira, Alexandre C. ; Gomez, Luz M. ; Bittencourt, Marcio Sommer et al. Manage cookies/Do not sell my data we use in the preference centre. (C) Bivariate density function of percentile ELSABrasil and percentile MESA. Arad Y, Spadaro LA, Goodman K, Newstein D, Guerci AD: Prediction of coronary events with electron beam computed tomography. 2002, 136: 161-72. By continuing you agree to the use of cookies. Scores above 300 suggest you are at a high risk of a heart attack and require prompt treatment. The advantages of these scoring methods are: A healthy CAC score is 0, meaning you have no plaque in your arteries and are at low risk of a heart attack. Here are some of the best exercises to keep your heart strong and reduce your risk of heart disease and stroke. We also estimated these probabilities, using models with all CHD risk factor predictors, for the specific clinical scenario described in the Introduction (a 60-year-old woman with hypertension and high cholesterol) and for several other scenarios. 2001, 141: 375-82. Subclinical atherosclerosis determined by coronary artery calcium deposition in patients with clinical familial hypercholesterolemia. Sung NS, Crowley WF, Genel Mea: Central challenges facing the national clinical research enterprise. At the MESA public website (http://www.mesa-nhlbi.org), an interactive form allows one to enter an age, gender, race/ethnicity, and CAC score to obtain a corresponding estimated percentile. An observed CAC of 8 is at the 91st percentile for individuals of the same age, sex, and race who are free of clinical ASCVD. 10.1056/NEJMcp023197. Men had greater calcium levels than women, and calcium amount and prevalence were steadily higher with increasing age. Background: Coronary artery calcium (CAC) is a measure of atherosclerotic burden and is well-validated for risk stratification in middle- to older-aged adults. JAMA. To use CAC Score Reference Values web tool please click 'Start' button below: Arterial age provides a convenient transformation of coronary artery calcium Below are the links to the authors original submitted files for images. On the other hand, CHD risk assessment is often based on the same type of limited information we had available on each of our patients, so the models we present are perhaps more easily applicable to common clinical situations than models based on more detailed clinical data. CAC score 1 to 99 and <75th percentile for age/sex/race/ethnicity indicates that there is subclinical atherosclerosis present. Results: Percentiles of CAC distribution were estimated with nonparametric techniques. P-values refer to a X2 test with 3 degrees of freedom comparing the expected frequencies based on each model with the observed frequencies. Coronary calcium score and cardiovascular risk. To use the score you will need information on the following risk factors: 2000, 283: 2546-51. Conclusions: In our sample of the Brazilian population, we observed significant differences in CAC by sex, age, and race. 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. 2018 May 4;14:75-80. doi: 10.2147/VHRM.S160669. To use a given CAC score result, however, one must know how that score compares with the score of an average person of the same sex, age and CHD risk factor profile. The information provided here can be used to examine whether a patient has a high CAC score relative to others with the same age, gender, and race/ethnicity who do not have clinical cardiovascular disease or treated diabetes. Your calcium score measures plaque burden on your arteries. CAC score >75th percentile, n (%) 13 (12.4) CAD, n (%) 44 (41.9) . The prevalence and correlates of subclinical atherosclerosis among adults with low-density lipoprotein cholesterol <70mg/dL: The Multi-Ethnic Study of Atherosclerosis (MESA) and Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). 10.1001/archinte.164.12.1285. . 2001, 141: 463-8. We evaluated whether statin intensity modifies CAC density at one year. Wilson PW, D'Agostino RB, Levy D, Belanger AM, Silbershatz H, Kannel WB: Prediction of coronary heart disease using risk factor categories. We estimated the 10-year risk of a first CHD event using published mathematical models based on the Framingham study [16]. sharing sensitive information, make sure youre on a federal This approach is not ideal, as the Ln(CAC score +1) is still grossly non-normal there are too many zero scores. All rights reserved. The analysis included 3616 individuals (54% female; mean age, 50 years). While CAC scores measured by the latest spiral computed tomography scanners appear to be similar to those generated by electron beam computed tomography [28], we cannot guarantee that our results apply to such scores. Hoff JA, Daviglus ML, Chomka EV, Krainik AJ, Sevrukov A, Kondos GT: Conventional coronary artery disease risk factors and coronary artery calcium detected by electron beam tomography in 30,908 healthy individuals. Mark J Pletcher. Use of the coronary artery calcium score (CAC) to assist in risk stratification of asymptomatic men and women is effective but limited to ages 45-84 years. We then used published model coefficients [16] to estimate the 10-year risk for each patient in our study. Dive into the research topics of 'Age, Gender, and Race-Based Coronary Artery Calcium Score Percentiles in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)'. 2002, 90: 168-73. Methods: The Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) is a prospective cohort study designed to investigate subclinical cardiovascular disease in 6 different centers of Brazil. While such an approach does allow multivariable modeling with ordinal logistic regression, it does not take full advantage of the continuous nature of the CAC score and may blur the important distinction between zero and non-zero scores. The .gov means its official. Only one of these was adequately powered [15], none adequately accounted for the abnormal distribution of CAC scores, and none yielded estimates usable for clinical decision-making. In a large cohort of US adults aged 30-45 years without symptomatic ASCVD, the probability of CAC >0 varied by age, sex, and race. There were 6110 included in the analysis, with 53% female and an average age of 62 years. statement and Similar to previous studies, individuals with self-reported coronary or cerebrovascular disease and those treated for diabetes mellitus were excluded from analysis. and Bensenor, {Isabela M.} and Lotufo, {Paulo A.}". Using US-derived percentiles in Brazilian individuals may lead to overestimating relative CAC burden in men and underestimating relative CAC burden in women. This online calculator is most appropriate for patients in the 45-85 year age 10.1016/S0735-1097(98)00583-X. the observed age, gender, total cholesterol, HDL cholesterol, smoking status, 10.1016/S0002-9149(00)01000-6. Scores between 100 and 300 indicate more calcium in your arteries and a higher risk of heart attack. Google Scholar. 2004, 291: 210-5. Our finding that high cholesterol was less strongly associated with the extent of CAC than other CHD risk factors is consistent with the other large study addressing this issue [15], and perhaps reflects effective medical treatment for hypercholesterolemia.
