conferenceObject Clinical Prediction Risk Scores Systematically Underestimate the Presence and Extent of Subclinical Atherosclerosis in Brazilian Women: The Brazilian Study of Longitudinal Health (ELSA-Brasil)(2014) BITTENCOURT, Marcio S.; PEREIRA, Alexandre C.; STANIAK, Henrique L.; SHAROVSKY, Rodolfo; GOMEZ, Luz Marina; MENDES, Vytor Hugo; BLANKSTEIN, Ron; NASIR, Khurram; BENSENOR, Isabela; LOTUFO, Paulo A.bookPart Dislipidemias(2014) STANIAK, Henrique Lane- Association between psoriasis and coronary calcium score(2014) STANIAK, Henrique L.; BITTENCOURT, Marcio Sommer; SANTOS, Itamar de Souza; SHAROVSKY, Rodolfo; SABBAG, Cid; GOULART, Alessandra C.; LOTUFO, Paulo A.; BENSENOR, Isabela M.Background: Emerging data suggests that chronic inflammatory disease, such as psoriasis, may be associated to coronary artery disease (CAD). Objective: Analyze the association between psoriasis and subclinical atherosclerosis using coronary calcium score (CAC). Methods: We investigated 221 participants with psoriasis and 718 age-and sex-matched controls without prior known CAD. All participants completed a questionnaire and underwent laboratory tests and a CAC exam. Logistic regression models adjusted for Framingham risk score (FRS) and C-reactive protein (hs-CRP) were built. CAC was included in the models as a binary variable with different cut off values. Results: Body-mass index, race, hypertension, HDL, LDL and hs-CRP were significantly associated with psoriasis presence and severity. Psoriasis severity was significantly associated with CAC (p = 0.04), particularly for very high CAC (>400) (p <0.01). The OR for severe psoriasis and CAC >400 was 2.45 (95%CI: 1.26-4.75) in unadjusted models. In a model adjusted for the FRS, this association was no longer significant, but a trend was noted (p = 0.09). No significant changes in the association were noted after the inclusion of hs-CRP in the model. Conclusion: Psoriasis is associated with higher CAC values, mainly in individuals with severe psoriasis. The current findings also suggest the potential involvement of other mechanisms beyond classical cardiovascular risk factors and inflammation in this association.
- Espessura do tecido subcutaneo como preditor independente de ruido em imagem de TC cardiaca(2014) STANIAK, Henrique Lane; SHAROVSKY, Rodolfo; PEREIRA, Alexandre Costa; CASTRO, Claudio Campi de; BENSENOR, Isabela M.; LOTUFO, Paulo A.; BITTENCOURT, Marcio SommerBackground: Few data on the definition of simple robust parameters to predict image noise in cardiac computed tomography (CT) exist. Objectives: To evaluate the value of a simple measure of subcutaneous tissue as a predictor of image noise in cardiac CT. Methods: 86 patients underwent prospective ECG-gated coronary computed tomographic angiography (CTA) and coronary calcium scoring (CAC) with 120 kV and 150 mA. The image quality was objectively measured by the image noise in the aorta in the cardiac CTA, and low noise was defined as noise < 30HU. The chest anteroposterior diameter and lateral width, the image noise in the aorta and the skin-sternum (SS) thickness were measured as predictors of cardiac CTA noise. The association of the predictors and image noise was performed by using Pearson correlation. Results: The mean radiation dose was 3.5 ± 1.5 mSv. The mean image noise in CT was 36.3 ± 8.5 HU, and the mean image noise in non-contrast scan was 17.7 ± 4.4 HU. All predictors were independently associated with cardiac CTA noise. The best predictors were SS thickness, with a correlation of 0.70 (p < 0.001), and noise in the non-contrast images, with a correlation of 0.73 (p < 0.001). When evaluating the ability to predict low image noise, the areas under the ROC curve for the non-contrast noise and for the SS thickness were 0.837 and 0.864, respectively. Conclusion: Both SS thickness and CAC noise are simple accurate predictors of cardiac CTA image noise. Those parameters can be incorporated in standard CT protocols to adequately adjust radiation exposure.
- Association between postprandial triglycerides and coronary artery disease detected by coronary computed tomography angiography(2014) STANIAK, Henrique L.; FILHO, Wilson Salgado; MINAME, Marcio H.; BENSENOR, Isabela M.; LOTUFO, Paulo A.; SHAROVSKY, Rodolfo; ROCHITTE, Carlos E.; BITTENCOURT, Marcio S.; SANTOS, Raul D.Background: Studies have demonstrated the association of severe anatomical coronary artery disease (CAD) with postprandial triglycerides (TG) concentrations. Nevertheless the relationship between less severe atherosclerosis plaque burden and postprandial TG is less established. Objective: to study the relationship between postprandial TG and CAD detected by coronary computed tomographic angiography (CTA). Material and methods: 130 patients who underwent an oral fat tolerance test were enrolled (85 with CAD detected by CTA and 45 without). Postprandial lipemia was studied by measuring TG from T0h to T6h with 2-h intervals, and analyzed the TG change over time using a longitudinal multivariable linear mixed effects model with the log normal of the TG as the primary outcome. Results: The majority of individuals with CAD had non-obstructive disease (63.3%) Patients with CAD had a slower clearance of postprandial TG change from 4 h to 6 h (p < 0.05) compared to patients without CAD. These results remained significant after adjustment for fasting TG and glucose, age, gender, body mass index, and waist circumference. However, those differences did not reach statistical significance after adjustment for fasting HDL-C. Conclusion: Patients with mild (<25% lumen obstruction) and moderate CAD (25-50% lumen obstruction) detected by coronary CTA had an impaired postprandial metabolism, with a delayed TG clearance, when compared to individuals with no CAD. This difference was partially explained by the lower HDL-C. Thus, though postprandial TG may contribute to the development of CAD, this association is partially related to low HDL-C.
- Coronary CT angiography for acute chest pain in the emergency department(2014) STANIAK, Henrique Lane; BITTENCOURT, Marcio Sommer; PICKETT, Christopher; CAHILL, Michael; KASSOP, David; SLIM, Ahmad; BLANKSTEIN, Ron; HULTEN, EdwardAcute chest pain in the emergency department (ED) is a common and costly public health challenge. The traditional strategy of evaluating acute chest pain by hospital or ED observation over a period of several hours, serial electrocardiography and cardiac biomarkers, and subsequent diagnostic testing such as physiologic stress testing is safe and effective. Yet this approach has been criticized for being time intensive and costly. This review evaluates the current medical evidence which has demonstrated the potential for coronary CT angiography (CTA) assessment of acute chest pain to safely reduce ED cost, time to discharge, and rate of hospital admission. These benefits must be weighed against the risk of ionizing radiation exposure and the influence of ED testing on rates of downstream coronary angiography and revascularization. Efforts at radiation minimization have quickly evolved, implementing technology such as prospective electrocardiographic gating and high pitch acquisition to significantly reduce radiation exposure over just a few years. CTA in the ED has demonstrated accuracy, safety, and the ability to reduce ED cost and crowding although its big-picture effect on total hospital and health care system cost extends far beyond the ED. The net effect of CTA is dependent also on the prevalence of coronary artery disease (CAD) in the population where CTA is used which significantly influences rates of post-CTA invasive procedures such as angiography and coronary revascularization. These potential costs and benefits will warrant careful consideration and prospective monitoring as additional hospitals continue to implement this important technology into their diagnostic regimen.
