Risk of coronary artery disease in celiac disease population

Background/Aims: Celiac disease (CD), a chronic autoimmune condition, is associated with systemic inflammation capable of causing extra intestinal manifestations. Chronic inflammatory process has been implicated in the pathogenesis of accelerated atherosclerosis. Studies examining the burden of coronary artery disease (CAD) in patients with CD are lacking. We evaluated the prevalence of CAD in patients with CD. Patients and Methods: Electronic health records from different health care systems were obtained utilizing a Health Insurance Portability and Accountability Act-compliant, patient de-identified web application. Among the 48,642,290 patients, 59,010 were diagnosed with CD. The remaining 48,583,280 patients without CD served as comparison controls. Results: The prevalence of CAD was significantly higher in patients with CD than in the controls [5140 (8.7%) vs. 2119060 (4.4%), P < 0.001], with the odds ratio (OR) being 2.09 (95% confidence interval [CI]: 2.03–2.15, P < 0.0001). There was a similarly higher prevalence among younger patients (age, <65 years) with CD compared with those without CD (3.72% vs 1.98% [OR: 1.85, 95% CI: 1.7488–1.9417, P < 0.0001). Conclusions: The prevalence of CAD increased nearly two-fold in patients with CD

Inflammatory bowel "Cardiac" disease: Point prevalence of atrial fibrillation in inflammatory bowel disease population

Background/Aim: Proinflammatory markers such as interleukin (IL)-6 have been closely associated with atrial fibrillation (AF). These markers are characteristically elevated in chronic inflammatory bowel disease (IBD) and positively correlate with disease activity. Although IBD and AF have similar pathogenesis, there have been very limited studies looking at their association. The aim of this study is to determine the prevalence of AF in patients with IBD. Patients and Methods: Medical records of patients with biopsy proven IBD (n = 203, both in and outpatient) were retrospectively reviewed. One hundred and forty-one IBD patients with documentary evidence of electrocardiograms (ECG's) were included. The "Anticoagulation and Risk Factors in Atrial Fibrillation (ATRIA)" study, a large cross-sectional study (n = 1.89 million) done to evaluate the prevalence of AF among the US population, was our control population. All ECGs available till December 2010 for each IBD patient were reviewed carefully for evidence of AF. We studied the prevalence of AF among IBD population and compared it to that of control (ATRIA) population. Results: The prevalence of AF was significantly higher among IBD patients compared with the ATRIA study patients (11.3% vs 0.9%, P < 0.0001). Additionally, the IBD patient population were much younger compared with the controls (64.4 ± 10.7 vs 71.2 ± 12.2, P = 0.02). Conclusion: AF has an overall higher prevalence across all age groups in IBD compared with the subjects of ATRIA study, which could be due to the chronic inflammatory state of IBD. Further studies are needed to study the association in detail

Outcomes of patients with severe tricuspid regurgitation and congestive heart failure

Objectives A substantial number of patients with severe tricuspid regurgitation (TR) and congestive heart failure (CHF) are medically managed without undergoing corrective surgery. We sought to assess the characteristics and outcomes of CHF patients who underwent tricuspid valve surgery (TVS), compared with those who did not. Methods Retrospective observational study involving 2556 consecutive patients with severe TR from the Cleveland Clinic Echocardiographic Database. Cardiac transplant patients or those without CHF were excluded. Survival difference between patients who were medically managed versus those who underwent TVS was compared using Kaplan-Meier survival curves. Multivariate analysis was performed to identify variables associated with poor outcomes. Results Among a total of 534 patients with severe TR and CHF, only 55 (10.3%) patients underwent TVS. Among the non-surgical patients (n=479), 30% (n=143) had an identifiable indication for TVS. At 38 months, patients who underwent TVS had better survival than those who were medically managed (62% vs 35%; p<0.001). On multivariate analysis, advancing age (HR: 1.23; 95% CI 1.12 to 1.35 per 10-year increase in age), moderate (HR: 1.39; 95% CI 1.01 to 1.90) and severe (HR: 2; 95% CI 1.40 to 2.80) right ventricular dysfunction were associated with higher mortality. TVS was associated with lower mortality (HR: 0.44; 95% CI 0.27 to 0.71). Conclusion Although corrective TVS is associated with better outcomes in patients with severe TR and CHF, a substantial number of them continue to be medically managed. However, since the reasons for patients not being referred to surgery could not be ascertained, further randomised studies are needed to validate our findings before clinicians can consider surgical referral for these patients.Revisión por pare
