    Autoimmune rheumatic diseases (ARDs) involve multiple organs including the heart and vasculature. Despite novel treatments, patients with ARDs still experience a reduced life expectancy, partly caused by the higher prevalence of cardiovascular disease (CVD). This includes CV inflammation, rhythm disturbances, perfusion abnormalities (ischaemia/infarction), dysregulation of vasoreactivity, myocardial fibrosis, coagulation abnormalities, pulmonary hypertension, valvular disease, and side-effects of immunomodulatory therapy. Currently, the evaluation of CV involvement in patients with ARDs is based on the assessment of cardiac symptoms, coupled with electrocardiography, blood testing, and echocardiography. However, CVD may not become overt until late in the course of the disease, thus potentially limiting the therapeutic window for intervention. More recently, cardiovascular magnetic resonance (CMR) has allowed for the early identification of pathophysiologic structural/functional alterations that take place before the onset of clinically overt CVD. CMR allows for detailed evaluation of biventricular function together with tissue characterization of vessels/myocardium in the same examination, yielding a reliable assessment of disease activity that might not be mirrored by blood biomarkers and other imaging modalities. Therefore, CMR provides diagnostic information that enables timely clinical decision-making and facilitates the tailoring of treatment to individual patients. Here we review the role of CMR in the early and accurate diagnosis of CVD in patients with ARDs compared with other non-invasive imaging modalities. Furthermore, we present a consensus-based decision algorithm for when a CMR study could be considered in patients with ARDs, together with a standardized study protocol. Lastly, we discuss the clinical implications of findings from a CMR examination.

    Pulmonary hypertension associates with malnutrition and body composition hemodialysis patients
    (2015) Genctoy, Gultekin; Arikan, Serap; Eldem, Olcay; 25410114
    Background/Aim: The prevalence of pulmonary hypertension (PH) is reported between 17 and 56% in hemodialysis (HD) patients. Pathogenesis of PH in HD patients is still unclear. Malnutrition associating impaired pulmonary function tests in HD patients previously reported. Present study aimed to investigate an association between PH and nutrition and inflammation HD patients. Patients/Methods: Total 179 HD patients (109 M, 70 F) were included. Pulmonary artery pressure (PAP) and ejection fraction (EF) percentage was determined by echocardiography after a midweek HD session. Bioimpedance analyses were performed after dialysis. Percent body fat mass truncal fat (%), total body water (%), body-mass index was determined. Serum 25-OH vitamin D, albumin, lipid parameters, C-reactive protein (CRP), calcium, phosphorus, parathyroid hormone, ferritin levels, and hemogram were studied. Results: Pulmonary hypertension (PAP >35 mmHg) was found in 48 (26.8%) of 179 patients studied. Body-mass index (BMI) was negatively correlated with PAP (r = -0.34; p = 0.02). HD vintage, prevalence of diabetes, sex, type of vascular access were not different between patients with PH and without PH. Patients with PH were older (68.1 +/- 14.4; 61.3 +/- 14.7; p = 0.005). Percent body fat (19.8 +/- 8.1% vs. 28.1 +/- 10%; p = 0.001), albumin (3.4 +/- 0.5 g/dl vs. 3.9 +/- 3.3 g/dl; p = 0.0001), truncal fat (16.8 +/- 10.7 vs. 26.4 +/- 10.5; p = 0.001), triglyceride (147.9 +/- 88.5 vs. 182.1 +/- 97.7 mg/dl; p = 0.03), and total cholesterol (146.9 +/- 34.5 vs. 169.5 +/- 43 mg/dl; p = 0.004) levels were significantly lower in patients with PH than with no PH. Logistic regression analysis revealed that increased percent body fat, albumin, and total cholesterol associate with a decreased risk of PH. Conclusion: Present study demonstrated a significant association between malnutrition and PH in HD patients. Those results should be confirmed by further prospective studies including cytokine levels and spirometric measurements.
