Red cell distribution width (RDW) and neutrophil/lymphocyte ratio (NLR) have been found to be associated with cardiovascular diseases. Only a few trials have investigated the correlation of these parameters with postoperative atrial fibrillation (AF). However, the correlation of these parameters in non-valvular AF is still unclear. We retrospectively analyzed consecutive AF patients from medical records and included 117 non-valvular AF patients (103 paroxysmal and 14 chronic AF). All subjects underwent physical examination and echocardiographic imaging. Complete blood counts (CBCs) were analyzed for hemoglobin, RDW, neutrophil and lymphocyte counts as well as mean corpuscular volume. Results of CBC tests within the previous year were also included and the averages were used. The demographic and echocardiographic properties of non-valvular AF group were comparable to the control group except for left atrial volumes which were increased in AF (median 33.1, IQR 26.3-41.1 cm(3) vs. median 26.4, IQR 24.2-28.9 cm(3); p = 0.01). RDW levels were significantly higher in the AF group (median 13.4 %, IQR 12.9-14.1 %) compared to the control (median 12.6 %, IQR 12.0-13.1 %; p = 0.01). NLR was not statistically different in the AF group and the controls (2.04 ± 0.94 vs. 1.93 ± 0.64, respectively; p = 0.32). Hs-CRP levels were higher in the AF group compared to the controls (median 0.84, IQR 0.30-1.43 mg/L vs. median 0.29, IQR 0.18-0.50 mg/L, respectively; p = 0.01). Multivariate logistic regression analysis revealed RDW (OR 4.18, 95 % CI 2.15-8.15; p = 0.01), hs-CRP (OR 3.76, 95 % CI 1.43-9.89; p = 0.01) and left atrial volume (OR 1.31, 95 % CI 1.06-1.21; p = 0.01) as the independent markers of non-valvular AF. Multivariate linear regression analysis revealed that hemoglobin levels (standardized β coefficient = -0.252; p = 0.01) and the presence of AF (standardized β coefficient = 0.336; p = 0.01) were the independent correlates of RDW levels. Elevated RDW levels, not NLR, may be an independent risk marker for non-valvular AF.

We found a relation between fQRS and late mortality. Fragmented QRS may be seen as a cautionary signal for extensive myocardial damage and thereby increased long-term mortality for patients with NSTEMI.

Constrictive pericarditis (CP) is caused by reduction in the elasticity of the pericardium resulting in impaired diastolic filling of the heart. All types of CP were thought to be irreversible in the past. This led to a belief that all patients with CP should undergo pericardiectomy. However, at present, it is well established that selected patients can be treated without pericardiectomy, leading to the concept of transient CP. Clinical improvement can be spontaneous or accomplished with empirical medical therapy administered for several months. As for chronic form, transient CP may not be recognized due to the difficulty in establishing the diagnosis because of the absence of any single method that is 100% sensitive and specific. It is worth considering the possibility of transient type when constrictive physiology is detected by noninvasive methods because correct diagnosis may prevent the inflamed pericardium from becoming the chronic fibrotic type that can be associated with more serious consequences including pericardiectomy.

Background: Efficacy of intravenous (IV) volume expansion in preventing contrast-induced acute kidney injury (CI-AKI) is well known. However, the role of oral hydration has not been well established. The aim of this work was to evaluate the efficacy of oral hydration in preventing CI-AKI. Methods: We prospectively randomized 225 patients undergoing coronary angiography and/or percutaneous coronary intervention in either oral hydration or IV hydration groups. Patients who have at least one of the high-risk factors for developing CI-AKI (advanced age, type 2 diabetes mellitus, anemia, hyperuricemia, a history of cardiac failure or systolic dysfunction) were included in the study. All patients had normal renal function or stage 1-2 chronic kidney disease. Patients in the oral hydration group were encouraged to drink unrestricted amounts of fluids freely whereas isotonic saline infusion was performed by the standard protocol in the IV hydration group. Results: CI-AKI occurred in 8/116 patients (6.9%) in the oral hydration group and 8/109 patients (7.3%) in the IV hydration group (p = 0.89). There was also no statistically significant difference between the two groups when different CI-AKI definitions were taken into account. Conclusion: Oral hydration is as effective as IV hydration in preventing CI-AKI in patients with normal kidney function or stage 1-2 chronic kidney disease, and who also have at least one of the other high-risk factors for developing CI-AKI.

Background: CHA 2 DS 2 -VASc score has been validated in risk prediction for stroke and thromboembolism in patients with atrial fibrillation (AF). Association of CHA 2 DS 2 -VASc score with higher risk of venous thromboembolism and pulmonary embolism (PE) has also been shown. In this study, we investigated the long-term prognostic value of CHA 2 DS 2 -VASc score in patients with acute pulmonary embolism (APE). Methods: Consecutive patients with APE presenting to our emergency department were retrospectively recruited. Patients with AF and who died secondary to causes other than PE were excluded from the study. The CHA 2 DS 2 -VASc score and pulmonary embolism severity index (PESI) were calculated. Results: Two hundred seventy seven participants were included in the study. The mortality rate was 18.7%. Twenty-two cases died within 30 days, and 30 cases died during the follow-up period (median: 13 months). The mean CHA 2 DS 2 -VASc score was significantly higher in dead patients compared to survivors (3.61 + 1.35 vs 1.95 + 1.52, P < .01). In multivariate regression analysis, systolic pulmonary artery pressure (hazard ratio [HR]: 1.03, 95% confidence interval [CI]: 1.01-1.06, P ¼ .02), PESI score (HR: 1.010, 95% CI: 1.004-1.017, P < .01), and CHA 2 DS 2 -VASc score (HR: 1.67, 95% CI: 1.19-2.16, P < .01) were found to be independently correlated with mortality. The patients whose CHA 2 DS 2 -VASc score was between 1 and 3 had 5.67 times and patients whose CHA 2 DS 2 -VASc score was 4 had 16.8 times higher risk of mortality compared to patients with CHA 2 DS 2 -VASc score ¼ 0. Conclusion: Patients with higher CHA 2 DS 2 -VASc scores had higher rates of mortality after APE.
