Background: This study is to examine relationship between coronary artery disease (CAD) and types of atrial fibrillation (AF) Methods: A total of 403 nonvalvular atrial fibrillation patients without known history of CAD underwent coronary artery calcium score (CACS) evaluation by multi-detector cardiac computed tomography. Clinical characteristics and CACS were compared between patients with persistent type of AF and paroxysmal type of AF. Results: The cohort comprised of 65% (279 of 430) male with a mean (SD) age of 63(10) years. Prevalence of persistent AF was 60% (259 of 430). Mean (SD) 10-year risk of CAD by Framingham score was 14(7)%. Median CACS was 22 (range 0-5402) with 75% CACS>0 (321 of 430). Compared to paroxysmal type, those with persistent type had higher prevalence of CAC>0 as shown in Figure1 and more history of hypertension (p<0.001) but less history of smoking (p0.004), statins use (p0.018) and warfarin use (p<0.001). There was no statistically significant difference in mean age (p0.783) and CAD risk by Framingham score (p0.477) between two groups. In multivariate analysis, persistent type is an independent predictor for CACS>0 (OR 1.938; 95%CI 1.197, 3.138; p0.007). Conclusion: In patients with AF, persistent type of AF is independently associated with CACS>0. Our findings suggest potential benefit from evaluation of CAD in this population.

Background: This study is to examine association of CHADS2 and CHA2DS2-VASc score with coronary artery disease (CAD) in nonvalvular atrial fibrillation (AF) Method: A total of 676 consecutive nonvalvular AF patients without known history of CAD underwent coronary artery calcium score (CACS) evaluation by multi-detector cardiac computed tomography. Clinical characteristics and CACS were compared between different CHADS2 and CHA2DS2-VASc score groups. Results: The cohort comprised of 68% (461 of 676) male with a mean ± SD age of 63 ± 10 years. Median 10-year risk of CAD by Framingham score was 11% (range 2%-53%). Median CHADS2 score was 1 (range 0-6) and median CHA2DS2-VASc score was 2 (range 0-8). Mean ± SD CACS was 215 ± 504. Compared to CHADS2 score ≤ 1, those with CHADS2 score > 1 had higher mean ± SD CACS (359 ± 738 VS 158 ± 359; p<0.001). CHADS2 score > 1 is associated with CACS > 0 (OR 1.751; 95%CI 1.168, 2.624; p 0.007) and CACS > 400 (OR 2.528; 95%CI 1.641, 3.896; p < 0.001). Similarly, compared to CHA2DS2-VASc score ≤ 1, those with CHA2DS2-VASc score > 1 had higher mean ± SD CACS (270 ± 586 VS 150 ± 376; p<0.001). CHA2DS2-VASc score > 1 is associated with CACS > 0 (OR 1.713; 95%CI 1.217, 2.409; p 0.002) and CACS > 400 (OR 2.683; 95%CI 1.678, 4.289; p < 0.001). Receiver operating characteristics of CHADS2 and CHA2DS2-VASc score models for CACS > 400 is shown in the figure. Conclusion: In nonvalvular AF patients, higher CHADS2 and CHA2DS2-VASc score are comparably associated with presence and severity of CAD.

Background and Objectives: Patients with AF are at increased risk for Coronary Artery Disease (CAD) owing to their shared etiologies and risk factors. This study aimed to assess the prevalence, cardiovascular risk factors, and used medications of CAD in AF patients. Materials and Methods: This retrospective, case-control study utilized data from the Jordanian Atrial Fibrillation (Jo-Fib) registry. Investigators collected clinical features, history of co-existing comorbidities, CHA2DS2-VASc, and HAS BLED scores for all AF patients aged >18 visiting 19 hospitals and 30 outpatient cardiology clinics. A multivariable binary logistic regression was used to asses for factors associated with higher odds of having CAD. Results: Out of 2000 patients with AF, 227 (11.35%) had CAD. Compared to the rest of the sample, those with CAD had significantly higher prevalence of hypertension (82.38%; p < 0.01), hypercholesterolemia (66.52%, p < 0.01), diabetes (56.83%, p < 0.01), and smoking (18.06%, p = 0.04). Patients with AF and CAD had higher use of anticoagulants/antiplatelet agents combination (p < 0.01) compared to the rest of the sample. Females had lower CAD risk than males (OR = 0.35, 95% CI: 0.24–0.50). AF Patients with dyslipidemia (OR = 2.5, 95% CI: 1.8–3.4), smoking (OR = 1.7, 95% CI: 1.1–2.6), higher CHA2DS2-VASc score (OR = 1.5, 95% CI: 1.4–1.7), and asymptomatic AF (OR = 1.9, 95% CI: 1.3–2.6) had higher risk for CAD. Conclusions: Owing to the increased prevalence of CAD in patients with AF, better control of cardiac risk factors is recommended for this special group. Future studies should investigate such interesting relationships to stratify CAD risk in AF patients. We believe that this study adds valuable information regarding the prevalence, epidemiological characteristics, and pharmacotherapy of CAD in patients with AF.

Background Patients with atrial fibrillation (AF) have an increased risk of ischaemic stroke. The risk can be predicted by the CHA2DS2-VASc score, in which the vascular component refers to previous myocardial infarction, peripheral artery disease and aortic plaque, whereas coronary artery disease (CAD) is not included. Objectives This article explores whether CAD per se or extent provides independent prognostic information of future stroke among patients with AF. Materials and Methods Consecutive patients with AF and coronary angiography performed between 2004 and 2012 were included. The endpoint was a composite of ischaemic stroke, transient ischaemic attack and systemic embolism. The risk of ischaemic events was estimated according to the presence and extent of CAD. Incidence rate ratios (IRR) were calculated in reference to patients without CAD and adjusted for parameters included in the CHA2DS2-VASc score and treatment with anti-platelet agents and/or oral anticoagulants. Results Of 96,430 patients undergoing coronary angiography, 12,690 had AF. Among patients with AF, 7,533 (59.4%) had CAD. Mean follow-up was 3 years. While presence of CAD was an independent risk factor for the composite endpoint (adjusted IRR, 1.25; 1.06–1.47), extent of CAD defined as 1-, 2-, 3- or diffuse vessel disease did not add additional independent risk information. Conclusion Presence, but not extent, of CAD was an independent risk factor of the composite thromboembolic endpoint beyond the components already included in the CHA2DS2-VASc score. Consequently, we suggest that significant angiographically proven CAD should be included in the vascular disease criterion in the CHA2DS2-VASc score.

Aim: Studies have evaluated the association of miRNA-423 C>A genotyping with the susceptibility to various diseases such cancers, atherosclerosis and inflammatory bowel disease but the results were contradictory. However, no studies have reported the association between miRNA-423 rs6505162 C>A polymorphism and susceptibility of coronary artery disease. MicroRNAs regulate expression of multiple genes involved in atherogenesis. Therefore, we investigated the association of microRNA-423C>T gene variations with susceptibility to coronary artery disease. Methodology: This study was conducted on 100 coronary artery disease patients and 117 matched healthy controls. The genotyping of the microRNA-423 rs6505162C>A was performed by using Amplification refractory mutation system PCR method (ARMS-PCR). Results: A significant difference was observed in the genotype distribution among the coronary artery disease cases and sex-matched healthy controls (P=0.048). The frequencies of all three genotypes CC, CA, AA reported in the patient’s samples were 55%, 41% and 4% and in the healthy controls samples were 55%, 41% and 4% respectively. Our findings showed that the microRNA-423 C>A variant was associated with an increased risk of coronary artery disease in codominant model (OR = 1.96, 95 % CI, 1.12-3.42; RR 1.35(1.05-1.75, p=0.017) of microRNA-423CA genotype and significant association in dominant model (OR 1.97, 95% CI (1.14-3.39), (CA+AA vs CC) and non-significant association for recessive model (OR=1.42, 95%CI=0.42-4.83, P=0.56, AA vs CC+CA).While, the A allele significantly increased the risk of coronary artery disease (OR =1.56, 95 % CI, 1.03-2.37; p=0.035) compared to C allele. Therefore, it was observed that more than 1.96, 1.97 and 1.56 fold increased risk of developing coronary artery disease. Conclusion: Our findings indicated that microRNA-423 CA genotype and A allele are associated with an increased susceptibility to Coronary artery disease.

METHODS Were selected 156 adult patients from a hospital in Maceió, Alagoas. Were evaluated with risk factors age, obesity, hypertension, diabetes mellitus, smoking, and dyslipidemia. PAOD screening was performed by the ankle-brachial index (ABI). The Mann-Whitney, chi-square, and Fisher’s exact tests were used. Confidence Interval of 95% and a significance of 5%. RESULTS 67.3% (n=105) males, 52.6% (n=82) elderly, 23.1% (n = 34) obese, 72.4% 6% (n=113) hypertensive, 34.6% (n=54) diabetics, 53.2% (n=83) smokers, 34.6% (n=54) dyslipidemic and 70.5% (n=110) with a family history of CAD. 16.7% (n=26) of the individuals presented PAOD. Three factors were associated with PAOD: age group ≥ 60 years (OR:3.656; p=0.005), diabetes mellitus (OR:2.625; p=0.024) and hypertension (OR:5.528; p=0.008). No significant difference was observed in the variables smoking, dyslipidemia, family history of CAD, and obesity. CONCLUSION The independent risk factors for PAOD were age, diabetes mellitus, and systemic arterial hypertension.

In an animal model, new evidence has been reported supporting the role of raet1e as an atherosclerosis-associated gene. Our objective was to establish if raet1e polymorphisms are associated with the risk of developing premature coronary artery disease (CAD) or with the presence of cardiometabolic parameters. After an informatic analysis, five polymorphisms were chosen and determined in 1158 patients with premature CAD and 1104 controls using 5′ exonuclease TaqMan genotyping assays. Standardized questionnaires were applied to all participants to obtain family medical history, demographic information, history of nutritional habits, physical activity, alcohol consumption, and pharmacological treatment. The functional effect of the rs7756850 polymorphism was analyzed by luciferase assays. Under different models, adjusted by age, gender, body mass index, current smoking, and type 2 diabetes mellitus, the rs6925151 (OR=1.250, pheterozygote=0.026; OR=1.268, pcodominant1=0.034), rs9371533 (OR=1.255, pheterozygote=0.024), rs7756850 (OR=1.274, pheterozygote=0.016; OR=1.294, pcodominant1=0.031), and rs9383921 (OR=1.232, pheterozygote=0.037) polymorphisms were associated with increased risk of premature CAD. When compared to the rs7756850 G allele, the C allele showed a decreased luciferase activity. In premature CAD patients, associations with low levels of adiponectin, with a high presence of hypertension, and with high levels of gamma-glutamyltransferase and total cholesterol were observed. In healthy controls, associations with a decrease in LDL pattern B, aspartate aminotransaminase, and hypo-α-lipoproteinemia were detected. An association of the raet1e polymorphisms with an increased risk of developing premature CAD and with cardiometabolic parameters has been shown for the first time. In addition, the functional effect of the rs7756850 polymorphism was defined.

Introduction: Preeclampsia (PE) represents a hypertensive pregnancy disorder that is associated with increased cardiovascular disease (CVD) risk. This increased risk has been attributed to accelerated atherosclerosis, with inflammation being a major contributor. Neutrophils play an important role in the onset and progression of atherosclerosis and have been associated with vascular damage in the placenta as well as the chronic inflammatory state in women with PE. We therefore investigated whether circulating neutrophil numbers or reactivity were associated with the presence and severity of subclinical atherosclerosis in women with a history of PE. Methods: Women aged 45–60 years with a 10 to 20 years earlier history of early onset preeclampsia (delivery <34 weeks of gestation) (n = 90), but without symptomatic CVD burden were screened for the presence of subclinical coronary artery disease (CAD) using both contrast-enhanced and non-contrast coronary CT angiography. Subclinical CAD was defined as a coronary artery calcium (CAC) score ≥100 Agatston Units and/or ≥50% coronary luminal stenosis. We assessed whether the numbers and activity of circulating neutrophils were associated with the presence of subclinical CAD and as secondary outcome measurements, with the presence of any calcium (CAC score > 0 AU) or stenosis, categorized as absent (0%), minimal to mild (>0 and <50%), and moderate to severe (≥50%) narrowing of the coronary artery. Blood was drawn just before CT and neutrophil numbers were assessed by flow cytometry. In addition, the presence of the chemokine receptors CXCR2 and CXCR4, which are known to be instrumental in neutrophil recruitment, and neutrophil activity upon stimulation with the bacterial peptide N-Formylmethionyl-leucyl-phenylalanine (fMLF) was assessed by flow cytometry. Results: Of the participating women, with an average age of 49 years, 13% (12 out of 90) presented with subclinical signs of CAD (CAC score ≥100 AU and/or ≥50% luminal stenosis), and 37% (33 out of 90) had a positive CAC score (>0). Total white blood cell count and neutrophil counts were not associated with the presence of subclinical CAD or with a positive CAC score. When assessing the presence of the chemokine receptors CXCR4 and CXCR2, we observed a slight decrease of neutrophil CXCR2 expression in women with CAC (median MFI 22.0 [interquartile range (IQR) 20.2–23.8]) compared to women without CAC (23.8 [IQR 21.6–25.6], p = 0.02). We observed no differences regarding neutrophil CXCR4 expression. In addition, expression of the early activity marker CD35 was slightly lower on neutrophils of women with subclinical CAD (median MFI 1.6 [IQR 1.5–1.9] compared to 1.9 [IQR 1.7–2.1] in women without CAD, p = 0.02). However, for all findings, statistical significance disappeared after adjustment for multiple testing. Conclusion: Our findings indicate that neutrophil counts and (re)activity are not directly associated with silent CAD disease burden and as such are not suitable as biomarkers to predict the presence of subclinical CAD in a high-risk population of women with a history of preeclampsia.

Background: Clinical implications of detecting subclinical coronary artery disease (CAD) in patients with atrial fibrillation (AF) are unclear. Methods: A total of 430 AF patients (age 63 ± 10 y, 65% male, 62% hypertensive, 16% diabetic, 42% dyslipidemic) without known CAD undergoing pre-procedural CT for catheter ablation were included. We evaluated the change in: 1) numbers of patients with CACS-diagnosed CAD who could potentially be on statin. 2) CHA2DS2-VASc score after incorporating CACS>100 (related to increased risk of stroke) into the original definition of vascular diseases who could potentially be on anticoagulants. Results: 1) Prevalence of subclinical CAD (CACS>0) was 74% (319/430) and 25% (106/430) had CACS>100. There were 62% (267/430) who were not on statin. Of these patients, 71% (190/267) had subclinical CAD while 21% (34/163) of statin users had CACS of 0. 2) The median original CHA2DS2-VASc score was 2. After incorporating CACS>100 into the original score, 24% (18/75) with the original score of 0 had the score changed to 1 (7/35 in persistent AF [PST-AF] and 11/40 in paroxysmal AF [PRX-AF]) (figure A) and 17% (22/131) with the original score of 1 had the score changed to ≥ 2 (10/83 in PST-AF and 12/48 in PRX-AF) (figure B). PRX-AF had more frequent increase in CHA2DS2-VASc score than PST-AF (p=0.035)(figure C). Conclusion: In AF patients without known history of CAD, detecting subclinical CAD by CACS potentially has important therapeutic implications for prevention forprogression of CAD and stroke.

Introduction: Statins have led to significant reductions in cardiovascular disease (CVD) events; however, a high level of residual cardiovascular risk remains. The REDUCE-IT trial showed additional benefit with icosapent ethyl to statins in reducing CVD morbidity and mortality. However, the safety of omega-3 ethyl esters with regards to atrial fibrillation (Afib) in patients with coronary artery disease (CAD) remains unclear. Hypothesis: We hypothesize that omega-3 ethyl esters may influence the risk of Afib or flutter in patients with CAD. Methods: In total, 285 CAD patients on statins were randomized to high dose omega-3 ethyl esters (1.86 g of Eicosapentaenoic acid [EPA] and 1.5 g of Docosahexaenoic acid [DHA]) or no omega-3 for 30 months. The incidence and recurrence of Afib or flutter was compared in those on EPA/DHA plus statin to statin alone (control). Results: A total of 240 patients were included in the analysis and no difference in baseline characteristics was observed (Table A). In total, 19 patients were in Afib or flutter during the trial: 12 in EPA/DHA and 7 in control (9.5% vs. 6.1%, respectively, p=0.33). The incidence of new onset Afib or flutter within 30 months was 7.2% and 4.9% in patients receiving omega-3 ethyl esters compared to controls, respectively (p=0.48). No significant difference in recurrence of Afib occurred among patients with a history of paroxysmal Afib receiving omega-3 ethyl esters compared to control (26.7% vs. 16.7%, respectively, p=0.53) (Table B). Conclusions: EPA/DHA did not increase the incidence of Afib or flutter in patients with established CAD. Further studies are warranted to better understand the effects of omega-3 ethyl esters on the cardiac conduction system.
