coronary calcium score percentile by age and gender
Another important limitation of this study is our lack of data on race/ethnicity our results may not apply to all ethnic groups. California Privacy Statement, Some approaches use only sensitivity and specificity from dichotomized CAC score cutoffs [21, 23], and others use CAC score-specific relative risks generated from a single study population [6, 24]. These probabilities ranged widely based on the value of the 10-year risk estimate, with the probability of measuring a zero CAC score going from 75% (at a 10-year risk of 2.5%) to 13% (at a 10-year risk of 25%) (Table 4). 1999, 84: 802-6. We first applied logistic regression to model the probability of a non-zero score, and then used linear regression to model the actual CAC score, log-transformed, for the subset of patients with non-zero values. The 75th percentile cut-off was stratified by gender and age and . There were 6110 included in the analysis, with 53% female and an average age of 62 years. and a coronary artery calcium score (Agatston units). The analysis included 3616 individuals (54% female; mean age, 50 years). Background: Statin therapy promotes the progression of coronary artery calcification (CAC). The post-test CHD risk estimates for each CAC score category were then calculated algebraically by assuming that the overall 1-year CHD risk estimate represents an average of the 1-year risk estimates from the four CAC score categories, weighted by the probabilities that an individual's score would fall into each category. What does my patient's coronary artery calcium score mean? 2022 Apr 6;77:100013. doi: 10.1016/j.clinsp.2022.100013. 2005-2023 Healthline Media a Red Ventures Company. If a score that would change your management is unlikely to occur, it may not be worth the money. 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. Am Heart J. Only two provide actual post-test risk estimates for specific clinical situations [23, 24]. Two-thirds of heart attacks are caused by the rupture of plaques which do not significantly narrow the coronary artery. By using this website, you agree to our values are based on participants in the MESA study who were free of clinical You do not need to have symptoms to get this procedure. 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. The prevalence of CAC >0 was 26% among White males, 16% among Black males, 10% among White females, and 7% among Black females. Finally, our data are limited in application to CAC scores measured by electron beam computed tomography with 3 mm slice thickness and the described protocol. JAT and MP helped design and interpret the analysis. A CAC score of 300 or higher or 75th percentile or higher for age, sex, and ethnicity is considered high risk. Conclusions: In our sample of the Brazilian population, we observed significant differences in CAC by sex, age, and race. 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. High coronary atherosclerotic burden was . I would be concerned that a CAC = 0 would suggest to the patient and provider that the risk factors do not need to be treated. Coronary calcification was defined as a plaque of at least 3 consecutive pixels (area = 1.03 mm2) with density 130 Hounsfield units. 2001, 141: 375-82. estimated probability of non-zero calcium, and the 25th, 50th, 75th, and 90th Its a low-cost and noninvasive way to measure your heart health. risk-equivalent of coronary artery calcium. We examined whether the effects of age were linear (as opposed to J-shaped, for example) by testing a quadratic term in the model containing only age and sex. (In press). government site. FOIA Diagnostic role of coronary calcium scoring in the rapid access chest . Current age, sex and presence of CHD risk factors were elicited by questionnaire from subjects and referring physicians. In these cases, and others in which the risk factor profile indicates very low or very high pre-test risk, the test is not likely to provide useful results, and the clinician might decide not to order the test. 2006 Feb 7;113(5):647-56. doi: 10.1161/CIRCULATIONAHA.105.552737. Subclinical atherosclerosis determined by coronary artery calcium deposition in patients with clinical familial hypercholesterolemia. T1 - Age, Gender, and Race-Based Coronary Artery Calcium Score Percentiles in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). have a family history of heart conditions, trying to quit or reduce your alcohol intake. Distributions and burden of coronary calcium in asymptomatic Saudi patients referred to computed tomography. Only the first CAC score was included for those who received more than one EBCT scan. As expected, CAC prevalence and burden were steadily higher with increasing age, as well as increased in men and in White individuals. Patients were labeled as smokers if they currently smoked or had quit smoking within the preceding 3 months. 2021 Jun 15;1(1):93-102. doi: 10.1016/j.jacasi.2021.05.002. (CAC) from Agatston units to age units, to a scale more easily appreciated by 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 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. We estimated the 10-year risk of a first CHD event using published mathematical models based on the Framingham study [16]. Methods: 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. And this helps optimize risk stratification in a primary . Please enable it to take advantage of the complete set of features! O'Rourke RA, Brundage BH, Froelicher VF, Greenland P, Grundy SM, Hachamovitch R, et al: American College of Cardiology/American Heart Association expert consensus document on electron-beam computed tomography for the diagnosis and prognosis of coronary artery disease. J Cardiovasc Comput Tomogr. Similar to previous studies, individuals with self-reported coronary or cerebrovascular disease and those treated for diabetes mellitus were excluded from analysis. Springer Nature. Adjusted for age and sex, low-risk individuals from the Brazilian population present with significantly lower CAC prevalence and burden compared with other low-risk individuals from other worldwide populations. The analysis included 3616 individuals (54% female; mean age, 50 years). 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)'. @article{46c7061a52f44dbe9a881abcd7cc67a0. The 2018 ACC/AHA Cholesterol Guideline suggests that coronary artery calcium (CAC) testing may be considered in adults 40-75 years of age without diabetes mellitus and with LDL-C levels 70 mg/dl-189 mg/dl at a 10-year atherosclerotic cardiovascular disease (ASCVD) risk of 7.5% to <20% (i.e., intermediate risk group) if a decision about statin therapy is uncertain. These estimates are only moderately sensitive to variation in the relative risk assumptions (Table 5), and may be easily calculated in any clinical scenario in which CHD risk factor data is available; see Table 5 for several other examples. ", or if their physician confirmed that such a condition was documented in their medical records. were between 45-84 years of age, and identified themselves as White, Arterioscler Thromb Vasc Biol. Comparison between actual and predicted CAC score distributions among a subset of the study population using three different modeling strategies. It may be converted to a percentile rank based on your age and gender. The https:// ensures that you are connecting to the Step 1: Enter your patient's clinical information (the red numbers). Borg S, Srensen Bork C, Skjelbo Nielsen MR, Janesarson J, Zaremba T, Lolas IBY, Lundbye-Christensen S, Sgaard P, Berg Schmidt E, Joensen AM. Percentiles of CAC for age by ethnic group. There were significant differences in calcium by race, and these associations differed across age and gender. (A) Probability of presenting with CAC score >0 for men and women according to age. 2007 May 29;115(21):2722-30. doi: 10.1161/CIRCULATIONAHA.106.674143. 10.1016/S0002-9149(00)01000-6. 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). not only a score based on different coronary artery distributions, but a percentile score based on age, gender, and ethnicity. 2023 BioMed Central Ltd unless otherwise stated. / Pereira, Alexandre C.; Gomez, Luz M.; Bittencourt, Marcio Sommer et al. 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. All authors reviewed and commented on multiple drafts of the manuscript and approved the final draft. You should not ingest caffeine the day of the procedure, but there is not much more you need to do unless directed by your doctor. Circulation. This site needs JavaScript to work properly. Results: Percentiles of CAC distribution were estimated with nonparametric techniques. Although the population distribution of CAC has been determined for several White populations, the distribution in ethnically admixed groups has not been well established. 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. . Use of Coronary Computed Tomography for Calcium Screening of Atherosclerosis. NCI CPTC Antibody Characterization Program. more easily understandable version of the CAC score (e.g. The procedure will expose you to a small amount of radiation, so a doctor will determine whether the test is necessary. 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. J Am Coll Cardiol. Additionally, if an observed calcium score is entered the program will Cite this article. Am J Cardiol. Coronary Artery Calcium Volume andDensity: Potential Interactions and Overall Predictive Value: TheMulti-Ethnic Study of Atherosclerosis. 2016 Wiley Periodicals, Inc. N2 - Background: Coronary artery calcium (CAC) has been demonstrated to independently predict the risk of cardiovascular events and all-cause mortality, especially among White populations. Age, Gender, and Race-Based Coronary Artery Calcium Score Percentiles in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Among the convincing support for CAC has been the utility of CAC = 0 and that CAC score provides better discrimination than age for incident ASCVD over long-term follow-up. Only dichotomous indicators of such conditions were used. Next, we calculated the probability, as described above, that that individual's CAC score would fall into each one of four standard CAC score categories [15, 18, 19] (0, 1100, 101400, and >400). 2023 American College of Cardiology Foundation. In such a case, we would certainly recommend both aspirin [2] and cholesterol-lowering medication [1] and would probably aim for a more aggressive LDL cholesterol goal of < 100 mg/dl [1]. It's a low-cost and noninvasive way to measure your heart health. tudy of Atherosclerosis with Validation in the Heinz Nixdorf Recall Study and the Dallas Heart Study. We also considered a censored normal distribution, which would have allowed a one-step Tobit regression analysis. We avoid using tertiary references. Again, the effects of age appeared to be linear (p = 0.16 for the quadratic age term). Age- and gender-adjusted percentiles for number of calcified plaques in coronary artery calcium scanning. 1990, 15: 827-32. Cookies policy. A noninvasive test called a coronary artery calcium (CAC) scan, which measures specks of calcium in the heart's arteries, can help predict a person's risk of heart disease. Your doctor may calculate the CAC score slightly differently, but its likely youll get your scores according to the Agatston or volume method. Asafu Adjaye Frimpong G, Owusu IK, Anyitey-Kokor IC, Wiafe-Kwakye CSNS, Aboagye E, Coleman NE, Amankwah P, Abaidoo NK. 2000, 101: 850-5. Treated diabetics were excluded from analysis. Men had greater calcium levels than women, and calcium amount and prevalence were steadily higher with increasing age. Epub 2018 Apr 28. 2001, 285: 2486-97. Electron beam computed tomographic coronary calcium score cutpoints and severity of associated angiographic lumen . Step 2: Choose an assumption about the coronary artery calcium score relative risks (optimistic or conservative). CAC Coronary artery calcium; CHD Coronary heart disease; Ln Natural logarithm. Using US-derived percentiles in Brazilian individuals may lead to overestimating relative CAC burden in men and underestimating relative CAC burden in women. A doctor may recommend measuring your coronary artery calcium (CAC) if youre at risk of coronary artery disease or another heart condition but have no symptoms. Furthermore, a historical indicator of past exposure to high blood pressure or high cholesterol, as we had access to in this study, may actually be more useful as a predictor of CAC than treated blood pressure measured at one point in time. Our analysis has a number of limitations, perhaps the most important being a lack of clinical detail about participants. Risk Factors for Coronary Artery Disease (CAD). Provided by the Springer Nature SharedIt content-sharing initiative. 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. How should a clinician use this CAC score (or any other) when assessing the CHD risk of a more typical patient, say a 60-year-old woman with hypertension and high cholesterol? 2002, 90: 168-73. While our analysis has some limitations, it provides methodology that will directly assist in the translation of research into practice. Would you like email updates of new search results? (2018). Mark J Pletcher. Am J Cardiol. Circulation. No direct measurements of blood pressure, lipids or glucose were taken for the purposes of this study.

The CAC score has become an important tool for helping both the patient and physician decision regarding treatment and intensity. sharing sensitive information, make sure youre on a federal TQC recruited the patients and collected the data. provide the estimated percentile for this particular score. Schaefer S: Will helical CT replace electron beam CT in the assessment of coronary calcium?. Scans were obtained within 100 ms and were electrocardiographically triggered at 6080% of the R-R interval. Age and sex were strong predictors of the presence of CAC in logistic regression models (Table 2). MeSH 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. According to current guidelines, this 60-year-old woman, whose 10-year CHD risk estimate is about 15%, should receive both aspirin and cholesterol-lowering drug therapy, aiming for a goal LDL cholesterol of 130 mg/dl [1, 2]. 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.

Our models should be applied to other similar cohorts for validation, and also applied in cohorts that include different racial/ethnic groups and different ways of measuring the CAC score before being used in these clinical situations. Combining information from the CAC score with information from conventional risk factors can change assessment of coronary heart disease risk to an extent that may be clinically important, especially when the pre-test 10-year risk estimate is intermediate. Approximately similar values were demonstrated by the highly sensitive analysis for cardiac troponin T: the 99th percentile for men was 20 ng/L, and for women it was 13 ng/L, while the overall (regardless of gender) calculated 99th percentile was 15 ng/L. An interactive webpage allows one to enter an age, sex, race, and CAC score to obtain the corresponding estimated percentile. The arterial age for a participant is We then developed a method for combining information from conventional risk factors and the CAC score (easy spreadsheet calculator attached), and we present several examples illustrating how that method may be applied in common clinical situations. Background: Newman AB, Naydeck BL, Sutton-Tyrrell K, Feldman A, Edmundowicz D, Kuller LH: Coronary artery calcification in older adults to age 99: prevalence and risk factors. abstract = "Background: Coronary artery calcium (CAC) has been demonstrated to independently predict the risk of cardiovascular events and all-cause mortality, especially among White populations. The result was adjusted for gender, ethnicity and age of the patient for classification in risk percentiles 10 10 Budoff MJ, Nasir K, McClelland RL, Detrano R, Wong N, Blumenthal RS, et al. Background: Coronary artery calcium (CAC) is a measure of atherosclerotic burden and is well-validated for risk stratification in middle- to older-aged adults. Before The higher your CAC score, the more you are at risk of heart attack. Thus, the information in this tool cannot necessarily be used to conclude that doi: 10.1136/openhrt-2022-002005. All-cause mortality by age and gender based on coronary artery calcium scores. The burden of coronary artery calcium (CAC)a strong correlate of total coronary atherosclerotic plaque 1 is associated with the risk of coronary heart disease (CHD) and cardiovascular disease (CVD).2, 3, 4 As such, CAC scoring is now incorporated in clinical practice guidelines given its demonstrated use as a powerful adjunct to both traditional risk factors5, 6, 7 and risk prediction . The authors harmonized three datasetsCARDIA (Coronary Artery Risk Development in Young Adults), the CAC Consortium (multicenter cohort physician referred for risk stratification), and the WRC (Walter Reed Cohort; armed forces)to study CAC in 19,725 asymptomatic Black and White individuals aged 30-45 years without known atherosclerotic cardiovascular disease (ASCVD). This process can start in your 20s, but your healthcare provider may not see it until there's an amount large enough to show up on imaging. Family history of premature coronary heart disease and coronary artery calcification: Multi-Ethnic Study of Atherosclerosis (MESA). Ann Epidemiol.
