eCollection 2021 Jun. Similar to previous studies, individuals with self-reported coronary or cerebrovascular disease and those treated for diabetes mellitus were excluded from analysis. Comparing patients on high (HIST) vs. low-to-intermediate intensity statin therapy (LIST), randomized controlled trials with a one-year follow-up failed to document a relevant difference in the Agatston score and CAC volume. Greenland P, Gaziano JM: Clinical practice. The technician may direct you to hold your breath for several seconds at a time to get the right image. Healthline Media does not provide medical advice, diagnosis, or treatment. JACC Cardiovasc Imaging. 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. California Privacy Statement, Blacks were lowest at the younger ages, and Chinese were lowest at the older ages. Previous approaches do generally take into account the pre-test probability of coronary heart disease, but none consider the expected distribution of CAC scores in the tested population after adjustment for conventional CHD risk factors. estimated probability of non-zero calcium, and the 25th, 50th, 75th, and 90th We identified a large sample of men and women without clinical CHD who presented for electron beam computed tomography scanning. Step 1: Enter your patient's clinical information (the red numbers). We evaluated whether statin intensity modifies CAC density at one year. CHD and Pediatrics and Quality Improvement. The procedure will expose you to a small amount of radiation, so a doctor will determine whether the test is necessary. 10.1001/archinte.164.12.1285. Using the case example presented in the Background section, we calculated that a 60-year-old woman with Stage I hypertension (140/90 mmHg) and high cholesterol (LDL cholesterol = 155 mg/dl, HDL cholesterol = 40 mg/dl) will have a 15% risk of suffering a CHD event in 10 years, according to the Framingham equation. There were 6110 included in the analysis, with 53% female and an average age of 62 years. 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. The proportion with cardiac risk factors was high, though only 9% were diabetic (Table 1). 2001, 87: 453-6. Selecting asymptomatic patients for coronary computed tomography or electrocardiographic exercise testing. Wong ND, Kouwabunpat D, Vo AN, Detrano RC, Eisenberg H, Goel M, et al: Coronary calcium and atherosclerosis by ultrafast computed tomography in asymptomatic men and women: relation to age and risk factors. 10.1016/S0002-9149(02)02445-1. Percentiles by Race Women, n Men, n; Age, y Age, y; 45-54 55-64 65-74 75-84 45-54 55-64 65-74 75-84; White, n . eCollection 2022. 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. The analysis included 3616 individuals (54% female; mean age, 50 years). Kaufmann RB, Sheedy PF, Maher JE, Bielak LF, Breen JF, Schwartz RS, et al: Quantity of coronary artery calcium detected by electron beam computed tomography in asymptomatic subjects and angiographically studied patients. Conventional CHD risk factors were also independent predictors of the presence of CAC (p < 0.001 in all cases). And this helps optimize risk stratification in a primary . . CAC >0 automatically placed all females at the >90th percentile. Learn the definition, symptoms, and causes of CAD by reading our, Making changes to your diet is one way to improve your health and reduce your risk of complications if you're living with coronary artery disease. After the procedure, a radiologist reads the X-rays and provides your doctor with an analysis. you are 55 years old, Few studies have investigated CAC in younger adults, and there is no calculator for determining age-, sex-, and race-based percentiles among individuals aged <45 years. Bensenor IM, Goulart AC, Pereira AC, Brunoni AR, Alencar A, Santos RD, Bittencourt MS, Telles RW, Machado LAC, Barreto SM, de Almeida-Pititto B, Janovsky CPS, Sgarbi JA, Tebar WR, Meneghini V, Junior FB, Ribeiro ACM, Pasoto SG, Pereira RMR, Bonf E, Sipahi AM, Santos IS, Lotufo PA. Clinics (Sao Paulo). Distribution of coronary artery calcium by race, gender, and age: results from 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). Mark J Pletcher. Sung NS, Crowley WF, Genel Mea: Central challenges facing the national clinical research enterprise. The authors would like to thank Paolo Raggi and Joseph Schwartz for their helpful input. 2009 January 1; 103(1): 5963. and transmitted securely. cardiovascular disease and treated diabetes at baseline. Distributions and burden of coronary calcium in asymptomatic Saudi patients referred to computed tomography. Associations of baseline measures of subclinical atherosclerosis (coronary artery calcium, abdominal aortic plaque, and abdominal aortic wall thickness) with MoCA scores measured at follow-up were examined in the group as a whole and in relation to age and ApoE4 status. The score can also factor in your age, gender, and other factors. 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. By continuing you agree to the use of cookies. During a single breath hold, 40 consecutive slices of 3 mm thickness were obtained starting at the level of the carina and proceeding to the level of the diaphragm. use of lipid lowering medication (yes/no), systolic blood pressure (mmHg), Healthline has strict sourcing guidelines and relies on peer-reviewed studies, academic research institutions, and medical associations. Europe PMC is an archive of life sciences journal literature. Accessibility J Am Coll Cardiol 2022;79:819-36). Breen JF, Schwartz RS. There were 6110 included in the analysis, with 53% female and an average age of 62 years. age. All-cause mortality by age and gender based on coronary artery calcium scores. 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. Only the first CAC score was included for those who received more than one EBCT scan. To use Arterial Age Calculator please click the button below. Using US-derived percentiles in Brazilian individuals may lead to overestimating relative CAC burden in men and underestimating relative CAC burden in women. Other tests for coronary artery disease may be more appropriate if you have symptoms or risk factors. Risk Factors for Coronary Artery Disease (CAD). Overall, Chinese and black women were intermediate, with their order dependent on age. Age-gender distribution of coronary artery calcium score in a black African population in Ghana. Your CAC score can indicate your risk of a heart attack. MP has received speaking and consulting fees from Bayer. The site is secure. volume2, Articlenumber:31 (2004) 2006;113(1):30-37. Coronary calcium predicts events better . Raggi P, Callister TQ, Cooil B, He ZX, Lippolis NJ, Russo DJ, et al: Identification of patients at increased risk of first unheralded acute myocardial infarction by electron-beam computed tomography. There were significant differences in calcium by race, and these associations differed across age and gender. Electron beam computed tomographic coronary calcium score cutpoints and severity of associated angiographic lumen . After exclusion of zero values, however, the log-transformed CAC score was approximately normally distributed (Figure 1). 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. 2000, 36: 1253-60. While we had information about conventional risk factors (hypertension, high cholesterol, diabetes mellitus and tobacco use), the data were only available from a questionnaire, and were not confirmed by direct measurement. 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. Using US-derived percentiles in Brazilian individuals may lead to overestimating relative CAC burden in men and underestimating relative CAC burden in women.". 1995, 70: 223-32. statement and Your doctor may suggest a CAC test if you: The CAC test is a CT scan that takes around 10 minutes. 2022 Apr 6;77:100013. doi: 10.1016/j.clinsp.2022.100013. 2017 Aug;10(8):845-854. doi: 10.1016/j.jcmg.2017.04.018. Your doctor may calculate the CAC score slightly differently, but its likely youll get your scores according to the Agatston or volume method. 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. 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. Privacy The Framingham 10-year CHD risk estimate was also a very strong predictor of coronary artery calcification, though the model containing the 10-year risk estimate as the only predictor was slightly less accurate (C-statistic = 0.74). Post WS, Shea S, Liu K, Watson KE, Folsom AR, Khera A, Ayers C, Coronary Artery Calcium Volume andDensity: Potential Interactions and Overall Predictive Value: TheMulti-Ethnic Study of Atherosclerosis. 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. The resulting numbers are summed for each coronary artery plaque, producing a CAC score. 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. Distribution of Coronary Artery Calcium by Age, Sex, and Race Among Patients 30-45 Years Old. 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. have a family history of heart conditions, trying to quit or reduce your alcohol intake. Arterial Age as a Function of Coronary Artery Calcium (from the Multi-Ethnic This does not apply to diabetics. Before 2000, 343: 1298-304. Scans were obtained within 100 ms and were electrocardiographically triggered at 6080% of the R-R interval. Two-thirds of heart attacks are caused by the rupture of plaques which do not significantly narrow the coronary artery. The "two-stage model predictions" use the coefficients presented in Tables 2 and 3 (the full model). Mayo Clin Proc. Actual prevalence measurements were from the 58- to 62-year-old non-smoking women in our study sample with hypertension, high cholesterol level, and no diabetes (n = 127). Male sex was a very strong predictor of the presence and extent of CAC women with the same CHD risk factor profile would be expected to develop CAC approximately 12 years later than men, and remain approximately 11 years behind men in the extent of their calcification. We estimated these probabilities, using models containing the 10-year risk estimate as the only predictor, for a range of 10-year risk estimates. As expected, CAC prevalence and burden were steadily higher with increasing age, as well as increased in men and in White individuals. We considered three sets of predictors: 1) age and sex, 2) age, sex, hypertension, high cholesterol, smoking, and diabetes, and 3) the Framingham 10-year CHD risk estimate. Pletcher, M.J., Tice, J.A., Pignone, M. et al. 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. a patient is "high risk", but can indicate whether they have a high calcium The Clinical Research Roundtable at the Institute of Medicine has identified translation of clinical research findings into improvements in medical care as the "next scientific frontier" [29]. Treated diabetics were excluded from analysis. J Am Coll Cardiol. 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. All statistical analyses were performed with Stata 7.0 (College Station, Texas). the Multi-Ethnic Study of Atherosclerosis (MESA). Atherosclerosis. government site. Prev Cardiol. Use of Coronary Computed Tomography for Calcium Screening of Atherosclerosis. We evaluated the ability of each logistic model to discriminate subjects at high and low risk for CAC using the C-statistic, and estimated the proportion of variability in the extent of CAC explained in each linear regression model using the adjusted-R2 statistic. The Ln(CAC+1) model predictions are from a linear regression model including all conventional CHD risk factors using Ln(CAC score +1) as a continuous outcome in a one-step modeling process (coefficients not presented). 2019 Nov-Dec;13(6):319-324. doi: 10.1016/j.jcct.2018.12.001. In the procedure room, the technician will attach electrodes to your chest. Krainik AJ, et al. 1990, 15: 827-32. JACC Asia. Our website services, content, and products are for informational purposes only. To fully appreciate the utility of this analysis, it may be worthwhile to discuss the example from the Background section further. Distribution of calcium score. NCI CPTC Antibody Characterization Program. Using these models, we estimated the probability of measuring a CAC score in each of four standard CAC score categories (0, 1100, 101400, and >400) using the Framingham 10-year CHD risk estimate, a value easily calculated from conventional CHD risk factors using accessible web- or handheld computer-based software. 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. Coronary artery calcium (CAC) has been demonstrated to independently predict the risk of cardiovascular events and all-cause mortality, especially among White populations. Your doctor may also order additional tests depending on your CAC score. Again, the Framingham 10-year CHD risk estimate was a very strong predictor of the extent of calcification, though when used alone in a model, it explained somewhat less of the variance (R2 = 0.11) than the full model (R2 = 0.17). An accurate estimate of 10-year CHD risk can be obtained using traditional risk factors and CAC. The amount of calcium in your arteries can affect how much oxygen and blood your heart receives. This machine adjusts your position as it takes X-rays of your heart. Ann Epidemiol. more easily understandable version of the CAC score (e.g. / Pereira, Alexandre C.; Gomez, Luz M.; Bittencourt, Marcio Sommer et al. title = "Age, Gender, and Race-Based Coronary Artery Calcium Score Percentiles in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)". Background: Coronary artery calcium (CAC) is a measure of atherosclerotic burden and is well-validated for risk stratification in middle- to older-aged adults. For women, whites had the highest percentiles and Hispanics generally had the lowest; in the oldest age group, however, Chinese women had the lowest values. Given this information, we would continue to recommend a healthy diet and exercise, but might decide that cholesterol-lowering medication is unnecessary [1], and that the benefits of aspirin in terms of CHD prevention do not outweigh the risk of hemorrhagic stroke associated with aspirin use [2]. N01-HC-95159/HC/NHLBI NIH HHS/United States, N01-HC-95165/HC/NHLBI NIH HHS/United States, N01-HC-95169/HC/NHLBI NIH HHS/United States. (B) Percentiles of CAC for age in men and women. 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. If her CAC score were zero (47% chance), our estimate of her 10-year CHD risk would be approximately halved (69%). In dealing with this issue, some researchers have used the Ln(CAC score +1) as an outcome in linear regression analyses [11, 12, 14, 20]. The percentiles of the CAC distribution were estimated with nonparametric techniques. Learn more about their complex relationship and how to handle your symptoms here. McClelland RL, Chung H, Detrano R, Post W, Kronmal RA. 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. 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. 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). CM provided statistical guidance and interpretation. Results from the Prospective Army Coronary Calcium Project. Step 4: Use the results to interpret a CAC score, or to decide whether or not to order a coronary artery calcium scan. There was no evidence that the effects of age were non-linear (i.e. 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. 1,2 eCollection 2022 Dec. Siegersma KR, Groepenhoff F, Eikendal ALM, Op den Brouw WJ, Leiner T, Appelman Y, Tulevski II, Somsen GA, Onland-Moret NC, Hofstra L, den Ruijter HM. The analysis included 3616 individuals (54% female; mean age, 50 years). 10.1016/S1047-2797(02)00277-6. Results: Percentiles of CAC distribution were estimated with nonparametric techniques. In our sample of the Brazilian population, we observed significant differences in CAC by sex, age, and race. 2023 American College of Cardiology Foundation. 10.1016/S0735-1097(00)00872-X. Current age, sex and presence of CHD risk factors were elicited by questionnaire from subjects and referring physicians. Terms and Conditions, The arterial age for a participant is tudy of Atherosclerosis with Validation in the Heinz Nixdorf Recall Study and the Dallas Heart Study. Mayo Clin Proc. Our strategy outperformed two other modeling strategies in predicting the actual CAC distribution among the 5862-year-old non-smoking non-diabetic women with hypertension and high cholesterol in our study sample (n = 127) (Figure 2). official website and that any information you provide is encrypted The technician will help position you flat on a table that will roll into a circular machine. Yang T, Doherty TM, Wong ND, Detrano RC: Alcohol consumption, coronary calcium, and coronary heart disease events. All rights reserved. The Multi-Ethnic Study of Atherosclerosis (MESA) provides a unique opportunity to examine the distribution of CAC on the basis of age, gender, and race/ethnicity in a cohort free of clinical cardiovascular disease and treated diabetes. sharing sensitive information, make sure youre on a federal Methods: the observed age, gender, total cholesterol, HDL cholesterol, smoking status, Hayden M, Pignone M, Phillips C, Mulrow C: Aspirin for the primary prevention of cardiovascular events: A summary of the evidence for the U.S. Preventive Services Task Force. Rumberger JA, Brundage BH, Rader DJ, Kondos G: Electron beam computed tomographic coronary calcium scanning: a review and guidelines for use in asymptomatic persons. Venuraju S, et al. and a coronary artery calcium score (Agatston units). There were 6110 included in the analysis, with 53% female and an average age of 62 years. Using questionnaire data collected from these patients about smoking habits and medical history (hypertension, high cholesterol and diabetes), we determined how conventional CHD risk factors, along with age and sex, affect CAC scores. Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available. author = "Pereira, {Alexandre C.} and Gomez, {Luz M.} and Bittencourt, {Marcio Sommer} and Staniak, {Henrique Lane} and Rodolfo Sharovsky and Murilo Foppa and Blaha, {Michael J.} Comparison between actual and predicted CAC score distributions among a subset of the study population using three different modeling strategies. This observation has led others to present only non-parametric percentile data without multivariable modeling [6, 810], but this approach does not allow adjustment for conventional CHD risk factors that we have shown are strong predictors of the CAC score. 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. The coronary artery calcium (CAC) score is an independent predictor of coronary heart disease risk [37], and therefore may help in deciding how aggressively to pursue cholesterol-lowering, anti-platelet therapy and other primary prevention strategies. Patients were labeled as smokers if they currently smoked or had quit smoking within the preceding 3 months. To use CAC Score Reference Values web tool please click 'Start' button below: Arterial age provides a convenient transformation of coronary artery calcium If a score that would change your management is unlikely to occur, it may not be worth the money. 2001, 21: 2051-8. Using the resulting multivariable models and published CAC score-specific relative risk estimates, we estimated post-test coronary heart disease risk in a number of different scenarios. 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. Among patients with non-zero CAC scores, age and sex remained strong predictors of the extent of coronary artery calcification, as measured by the Ln(CAC score) (Table 3). 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. Percentiles of CAC distribution were estimated with nonparametric techniques. Arad Y, Newstein D, Cadet F, Roth M, Guerci AD: Association of multiple risk factors and insulin resistance with increased prevalence of asymptomatic coronary artery disease by an electron-beam computed tomographic study. We then used published model coefficients [16] to estimate the 10-year risk for each patient in our study. https://orcid.org Abbreviations: CAC, coronary artery calcium; ELSA, Brazilian Longitudinal Study of Adult Health; MESA, MultiEthnic Study of Atherosclerosis. Springer Nature. Combining information from the coronary artery calcium score with information from conventional risk factors to estimate coronary heart disease risk. 10.1067/mhj.2001.113069. Using US-derived percentiles in Brazilian individuals may lead to overestimating relative CAC burden in men and underestimating relative CAC burden in women. 1999, 84: 802-6. Raggi P, Cooil B, Callister TQ: Use of electron beam tomography data to develop models for prediction of hard coronary events. Treatments for coronary artery disease include lifestyle changes, medications, and additional procedures in some cases. Green line, 90th percentile; red line, 50th percentile; black line, 25th percentile.
