Coronary calcium score in patients with post-surgical hypoparathyroidism.

Objective: This study aimed to evaluate the cardiovascular risk of patients with post-surgical hypoparathyroidism through coronary calcium score (CACS) evaluation andcardiovascular risk calculators. Subjects and methods: Patients with post-surgical hypoparathyroidism (HG = 29) were compared to a control group (CG = 29), matched by sex and age. Demographic and clinical data were captured by a questionnaire or patient files. Both groups performed a thoracic-computed tomography to evaluate the CACS and the cardiovascular risk was calculated by two risk calculators. Results: In the HG, the supplementation of calcium varied between 500 to 2,000 mg/day and the mean calcitriol was 0.5 ± 0.29 mcg/day. The mean serum calcium and phosphorus were 8.32 ± 0.68 and 4.92 ± 0.87 mg/dL, respectively, and in the range recommended for hypoparathyroidism. The Brazilian Society of Cardiology's risk calculator showed a difference among groups, with no patient in the HG with low risk, but the CACS was similar. A positive CACS in the HG was associated with obesity and high BMI but not with calcium and/or vitamin D supplementation. Conclusion: In conclusion, patients with hypoparathyroidism did not show increased CACS, and it was not related to supplementation.

Ischemic stroke caused by large-artery atherosclerosis: a red flag for subclinical coronary artery disease.

Background: The coronary calcium score (CAC) measured on chest computerized tomography is a risk marker of cardiac events and mortality. We compared CAC scores in two multiethnic groups without symptomatic coronary artery disease: subjects in the chronic phase after stroke or transient ischemic attack and at least one symptomatic stenosis ≥50% in the carotid or vertebrobasilar territories (Groupathero) and a control group (Groupcontrol). Methods: In this cross-sectional study, Groupathero included two subgroups: GroupExtraorIntra, with stenoses in either cervical or intracranial arteries, and GroupExtra&Intra, with stenoses in at least one cervical and one intracranial artery. Groupcontrol had no history of prior stroke/transient ischemic attacks and no stenoses ≥50% in cervical or intracranial arteries. Age and sex were comparable in all groups. Frequencies of CAC ≥100 and CAC > 0 were compared between Groupathero and Groupcontrol, as well as between GroupExtraorIntr, GroupExtra&Intra, and Groupcontrol, with bivariate logistic regressions. Multivariate analyses were also performed. Results: A total of 120 patients were included: 80 in Groupathero and 40 in Groupcontrol. CAC >0 was significantly more frequent in Groupathero (85%) than Groupcontrol (OR, 4.19; 1.74-10.07; p = 0.001). Rates of CAC ≥100 were not significantly different between Groupathero and Groupcontrol but were significantly greater in GroupExtra&Intra (n = 13) when compared to Groupcontrol (OR 4.67; 1.21-18.04; p = 0.025). In multivariate-adjusted analyses, "Groupathero" and "GroupExtra&Intra" were significantly associated with CAC. Conclusion: The frequency of coronary calcification was higher in subjects with stroke caused by large-artery atherosclerosis than in controls.

Phytosterol consumption and markers of subclinical atherosclerosis: Cross-sectional results from ELSA-Brasil.

BACKGROUND AND AIMS: Phytosterol (PS) consumption is associated with lower total and LDL-cholesterol (LDL-c) concentrations, but its impact on cardiovascular risk is unclear. This study assessed the effect of usual intake of PS on markers of subclinical atherosclerosis in the Longitudinal Study of Adult Health (ELSA-Brasil). METHODS AND RESULTS: This cross-sectional study included 2560 participants of ELSA-Brasil, aged 48 (43-54) years, with available food frequency questionnaires (FFQ), coronary artery calcium (CAC) scores, carotid intima media thickness (cIMT), and carotid-femoral pulse wave velocity (cf-PWV), at baseline. Several logistic and linear regression models were used, and significance level was set at a P < 0.05. Mean values (SD) for PS consumption were 256 (198) mg/day, CAC 22.78 (110.54) Agatston Units, cf-PWV 9.07 (1.60) m/s and cIMT 0.57 (0.12) mm. PS consumption in Q4 was associated with lower total- and LDL-c levels, and with higher percentiles of cf-PWV (P < 0.001). Proportion of subjects in Q4 of PS consumption was 1.5 times higher among individuals in cf-PWV Q4, than in Q1 (P = 0.002, for comparisons among quartiles). There was a trend (P = 0.003) for higher cf-PWV with higher PS intake. In crude logistic and linear regressions, PS intake was associated with cf-PWV. In the adjusted models, these associations disappeared. No associations were found between PS and cIMT or CAC. CONCLUSIONS: In this large and apparently healthy cross-sectional sample from ELSA-Brasil, usual PS consumption was associated with lower total- and LDL-cholesterol, but not with markers of subclinical atherosclerosis.

Score de calcio coronario en la estratificación de riesgo cardiovascular / Coronary calcium score in cardiovascular risk stratification / Escore de cálcio coronariano na estratificação de risco cardiovascular

Resumen: La enfermedad cardiovascular (CV) es la primera causa de muerte en el mundo y en Uruguay. La prevención CV consiste en un enfoque clínico terapéutico dirigido a disminuir la morbimortalidad CV basado en el riesgo estimado de cada individuo. La estratificación de riesgo CV en individuos asintomáticos con el objetivo de guiar y establecer medidas de tratamiento preventivo es de crucial importancia. Para ello, en el mundo se utilizan scores de riesgo clínico que incluyen el score de riesgo Framingham, el SCORE y el Pooled Cohort Equations, entre otros. Sin embargo, estos scores no son herramientas perfectas de predicción. Los scores estiman el riesgo basado en la distribución del factor de riesgo en una población, mientras que el score de calcio coronario (SCC) es un marcador directo de aterosclerosis coronaria en un individuo determinado. En las últimas tres décadas, numerosos estudios han demostrado la utilidad del SCC como herramienta para la estratificación de riesgo CV. Es, por lo tanto, importante entender cómo, para qué y por qué se realiza.

Summary: Cardiovascular disease is the leading cause of death in the world and in Uruguay. Cardiovascular prevention consists of a therapeutic clinical approach with the objective of reducing cardiovascular morbidity and mortality based on the estimated cardiovascular risk of each person. Thus, cardiovascular risk stratification in asymptomatic individuals with the objective of guide and establish preventive treatment measures is of crucial importance. For this, clinical risk scores are used worldwide, including the Framingham risk score, the SCORE1 and the Pooled Cohort Equations2, among others. However, these risk scores are not perfect prediction tools. While these global risk scores estimate risk based on the distribution of the risk factor in a population, the coronary calcium score is a direct marker of coronary atherosclerosis in a given individual. In the last three decades, numerous studies have demonstrated the usefulness of the coronary calcium score as a cardiovascular risk stratification tool. It is therefore important to understand how, for what and why it is done.

Resumo: As doenças cardiovasculares são a principal causa de morte no mundo e o Uruguai. A prevenção cardiovascular consiste em uma abordagem clínica terapêutica que visa reduzir a morbimortalidade cardiovascular com base no risco cardiovascular estimado de cada indivíduo. Assim, a estratificação do risco cardiovascular em indivíduos assintomáticos com o objetivo de orientar e estabelecer medidas de tratamento preventivo é de importância crucial. Para isso, os escores de risco clínico são utilizados em todo o mundo, incluindo o escore de risco de Framingham, o SCORE1 e as equações de coorte agrupadas2, entre outros. No entanto, essas pontuações de risco não são ferramentas de previsão perfeitas. Embora essas pontuações globais de risco calculem o risco com base na distribuição do fator de risco em uma população, o escore de cálcio coronariano é um marcador direto da aterosclerose coronariana em um determinado indivíduo. Nas últimas três décadas, numerosos estudos demonstraram a utilidade do escore de cálcio coronariano como uma ferramenta para estratificação de risco cardiovascular. Portanto, é importante entender como, para quê e por que isso é feito.

Valor do escore de calcio coronariano para prever a gravidade ou complexidade da doenca arterial coronariana / Value of coronary artery calcium score to predict severity or complexity of coronary artery disease

FUNDAMENTO: A previsão de gravidade ou complexidade da doença arterial coronariana (DAC) é valiosa devido ao aumento do risco de eventos cardiovasculares. Embora a associação entre o escore do cálcio arterial coronariano (CAC), e a gravidade da DAC pelo escore Gensini não tenha sido utilizado, já foi anteriormente demonstrado. Não há informações sobre a associação entre o escore do CAC total e a complexidade da DAC. OBJETIVOS: Investigar a associação entre a gravidade ou complexidade da doença arterial coronariana (DAC), avaliada pelo escore Gensini e SYNTAX (SS), respectivamente, e o escore do cálcio arterial coronariano (CAC), um método não invasivo para avaliação de DAC em pacientes sintomáticos com DAC significativa. MÉTODOS: Duzentos e quatorze pacientes foram incluídos. A pontuação total do CAC foi obtido antes da angiografia. A severidade e complexidade da DAC foram avaliadas pelo escore Gensini e SS, respectivamente. Foram analisadas as associações entre parâmetros clínicos e angiográficos e o escore total do CAC. RESULTADOS: A mediana do escore total do CAC foi de 192 (23,0-729,8), e correlacionou-se positivamente com ambos os escores Gensini (r: 0,299, p < 0,001) e ES (r: 0,577, p < 0,001). Na análise multivariada associou-se independentemente com a idade (ß: 0,154, p: 0,027), sexo masculino (ß: 0,126, p: 0,035) e ES (ß: 0,481, p < 0,001). A análise da curva ROC (Receiver Operating Characteristics) revelou um valor de corte > 809 para ES > 32 (tercil de SS alto). CONCLUSÃO: Em pacientes sintomáticos com DAC significativa, o escore total de CAC foi independentemente associado com SS e os pacientes com SS > 32 podem ser detectados através de escore Agatston alto. .

BACKGROUND: Prediction of severity or complexity of coronary artery disease (CAD) is valuable owing to increased risk for cardiovascular events. Although the association between total coronary artery calcium (CAC) score and severity of CAD, Gensini score was not used, it has been previously demonstrated. There is no information about the association between total CAC score and complexity of CAD. OBJECTIVES: To investigate the association between severity or complexity of coronary artery disease (CAD) assessed by Gensini score and SYNTAX score (SS), respectively, and coronary artery calcium (CAC) score, which is a noninvasive method for CAD evaluation in symptomatic patients with accompanying significant CAD. METHODS: Two-hundred-fourteen patients were enrolled. Total CAC score was obtained before angiography. Severity and complexity of CAD was assessed by Gensini score and SS, respectively. Associations between clinical and angiographic parameters and total CAC score were analyzed. RESULTS: Median total CAC score was 192 (23.0-729.8), and this was positively correlated with both Gensini score (r: 0.299, p<0.001) and SS (r: 0.577, p<0.001). At multivariate analysis, it was independently associated with age (ß: 0.154, p: 0.027), male gender (ß: 0.126, p: 0.035) and SS (ß: 0.481, p< 0.001). Receiver-operating characteristic (ROC) curve analysis revealed a cut-off value > 809 for SS >32 (high SS tertile). CONCLUSION: In symptomatic patients with accompanying significant CAD, total CAC score was independently associated with SS and patients with SS >32 may be detected through high Agatston score. .

Precisión diagnóstica del espesor íntima-media carotídeo para la detección de aterosclerosis coronaria: utilidad en la práctica clínica / Diagnostic Accuracy of Carotid Intima-Media Thickness to Detect Coronary Atherosclerosis: usefulness in Clinical Practice

Introducción El espesor íntima-media carotídeo (EIMC) es un marcador independiente de riesgo cardiovascular. El puntaje de calcio coronario (PCC) es un predictor superior al EIMC, pero de costo elevado y en nuestro país pocos pacientes pueden acceder a su medición. Objetivos 1) Evaluar la precisión diagnóstica del EIMC para la detección de un PCC > 0. 2) Determinar el punto de corte óptimo del EIMC para discriminar entre la presencia o la ausencia de calcio coronario. Material y métodos Estudio descriptivo transversal de muestras consecutivas obtenidas en los consultorios de prevención cardiovascular. Se midió el EIMC medio y máximo mediante un eco-Doppler ca-rotídeo. Se efectuó una tomografía computarizada de 64 pistas para la evaluación del PCC. Se determinó la precisión diagnóstica del EIMC para la detección de un PCC > 0 mediante un análisis ROC. Resultados Se incluyeron 202 sujetos consecutivos que participan de un programa de prevención primaria. Características de la población (media ± desviación estándar): edad 57 ± 13 años, sexo femenino: 49%, tabaquismo: 13%, estatinas: 37%, diabetes mellitus: 13%, puntaje de Framingham en no diabéticos: 9% ± 7%, EIMC medio: 0,953 ± 0,342 mm, EIMC máximo: 1,383 ± 0,679 mm, prevalencia de placa aterosclerótica carotídea: 37% y de PCC > 0: 62%. Las correlaciones entre el EIMC medio y máximo y el PCC fueron moderadas (r = 0,56 y r = 0,55, respectivamente). El área bajo la curva ROC del EIMC máximo fue de 0,822 (IC 95% 0,763-0,880) y la del EIMC medio fue de 0,829 (IC 95% 0,771-0,888). El punto de corte óptimo del EIMC máximo para discriminar entre PCC > 0 o PCC = 0 fue de = 1,01 mm y la sensibilidad, la especificidad, el valor predictivo positivo (VPP) y el valor predictivo negativo (VPN) fueron del 78%, 75%, 83% y 67%, respectivamente. El punto de corte óptimo del EIMC medio para discriminar entre PCC > 0 o PCC = 0 fue = 0,82 mm y la sensibilidad, la especificidad, el VPP y el VPN fueron del 77%, 78%, 85% y 67%, respectivamente. Conclusiones En esta población predominantemente de riesgo bajo, la precisión diagnóstica del EIMC para detectar PCC > 0 fue moderada. Una ecografía Doppler carotídea "normal" no excluyó la presencia de aterosclerosis subclínica coronaria. Estos resultados podrían mejorar la selección de pacientes que requieran la medición del PCC para estratificar el riesgo cardiovascular.

Background Carotid intima-media thickness (CIMT) is an independent marker of cardiovascular risk. Coronary artery calcium score (CACS) is better than CIMT to predict coronary artery disease; yet, few patients have access to this evaluation in our country due to its high cost. Objectives The aim of this study was: 1) to evaluate the diagnostic accuracy of CIMT to detect CACS >0. 2) To determine an optimal cut-off point of CIMT to discriminate between the presence and the absence of coronary artery calcium. Methods We conducted a cross-sectional descriptive study of consecutive samples obtained in the outpatient clinic of cardiovascular prevention. Mean and maximum CIMT were measured using carotid Doppler ultrasound. Carotid artery atherosclerotic plaque (CAP) was evaluated with a 64-row multidetector computed tomography. The diagnostic accuracy of CIMT to detect CACS >0 was determined by ROC analysis. Results A total of 202 consecutive subjects participating in a primary prevention program were included. Population characteristics were (mean ± standard deviation): age 57±13 years, female gender: 49%, smokers: 13%, statins: 37%, diabetes mellitus: 13%, Framingham risk score in non diabetics: 9%±7%, mean CIMT: 0.953±0.342 mm, maximum CIMT: 1.383±0.679 mm, prevalence of carotid artery atherosclerotic plaque: 37% and of CACS >0: 62%. The correlations between mean and maximum CIMT and CACS were poor (r=0.393 and r=0.376, respectively). The area under the ROC curve of maximum CIMT was 0.822 (95% CI 0.763-0.880) and that of mean CIMT was 0.829 (95% CI 0.771-0.888). The optimal cut-off point of maximum CIMT to discriminate between CACS >0 or CACS = 0 was =1.01 mm and sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were 78%, 75%, 83% y 67%, respectively. The optimal cut-off point of mean CIMT to discriminate between CACS >0 or CACS = 0 was =0.82 mm and sensitivity, specificity, PPV and NPV were 77%, 78%, 85% and 67%, respectively. Conclusions In this low-risk population, the diagnostic accuracy of CIMT to detect CACS >0 was moderate. A "normal" carotid Doppler ultrasound did not exclude the presence of subcli-nical coronary artery atherosclerosis. These results might improve selection of patients undergoing CACS to stratify cardiovascular risk.

Asociación entre algunos factores de riesgo cardiovascular y el puntaje de calcio coronario en pacientes sintomáticos / Association between some cardiovascular risk factors and coronary calcium scoring in symptomatic patients

Introducción: el conocimiento de la carga aterosclerótica global individual es de alta importancia. Su asociación con los factores de riesgo cardiovascular no está bien establecida. Objetivo: determinar la asociación entre algunos factores de riesgo cardiovascular y el puntaje de calcio coronario. Métodos: se estudiaron 169 pacientes sintomáticos con sospecha de cardiopatía isquémica, que de forma consecutiva se realizaron el puntaje de calcio, se identificaron los factores de riesgo y para determinar su asociación se utilizó el modelo de regresión logística. Resultados: el estudio incluyó 106 mujeres y 63 hombres, edad media 59,6 ± 10,8 años vs. 59,5 ± 11,0 años, respectivamente. El 51,9 pociento de las mujeres y el 34,9 porciento de los hombres tuvieron un score = 0. La dosis media de radiación efectiva fue de 0,82 mSv. Las variables sexo masculino > 55 años, femenino > 65 años, hábito de fumar, diabetes mellitus, edad, número de factores de riesgo, VLDL, triglicéridos y HDL, mostraron asociación significativa con algunos de los valores de corte del puntaje de calcio establecidos. En el análisis multivariado, la edad, el hábito de fumar, los triglicéridos y la HDL como factor protector, tuvieron coeficientes significativamente diferentes de 0, siendo la edad la que tuvo mayor influencia en el valor del score de calcio > 0 y ³ 100 y la HDL en el valor ³ 400. Conclusiones: solamente algunos factores de riesgo muestran asociación con el puntaje de calcio coronario, fundamentalmente la edad y los niveles de HDL como factor protector

Introduction: knowledge of an individual's overall atherosclerotic burden is extremely important. Its association with cardiovascular risk factors has not been well established. Objective: determine the association between some cardiovascular risk factors and coronary calcium scoring. Methods: a study was conducted of 169 symptomatic patients with suspected ischemic heart disease. The patients consecutively underwent calcium scoring and risk factor identification. Association between the two values was determined by logistic regression modeling. Results: 106 patients were women and 63 were men; mean age was 59.6 ± 10.8 and 59.5 ± 11.0, respectively. 51.9 percent of the women and 34.9 percent of the men had a score = 0. Mean effective radiation dose was 0.82 mSv. The variables male patient aged > 55, female patient aged > 65, smoking, diabetes mellitus, age, number of risk factors, VLDL, triglycerides and HDL showed a significant association with some of the calcium score cut-off values established. In the multivariate analysis, age, smoking, triglycerides and HDL as a protective factor, exhibited coefficients significantly different from 0, with age exerting the greatest influence upon the calcium score > 0 and ³ 100 value, and HDL upon the ³ 400 value. Conclusions: only some risk factors show an association with coronary calcium score, particularly age and HDL levels as a protective factor
