The effect of dialysis type on left atrial functions in patients with end‐stage renal failure: A propensity score‐matched analysis

Self Cite

Purpose Atrial fibrillation (AF) is relatively frequent in the postoperative period, and is associated with an increased frequency of adverse events. The role of right atrial (RA) volume and functions in the development of AF is unknown. In this study, we investigated the effect of RA echocardiographic indices on AF development in the postoperative period. Method We enrolled 142 consecutive patients who underwent coronary artery bypass surgery, and assigned them into two groups depending on the occurrence or not of AF development in the postoperative period. Results A propensity score matching analysis was performed to balance the groups, and 37 pairs were eventually included in the analysis. The median age was 67.5 (63‐75) years and 73.3% of them were males. In the univariate analysis, right atrial volume index (RAVi), right atrial strain during reservoir phase (RASr), left ventricular global longitudinal strain, right ventricular strain, left atrial volume index, left atrial strain during reservoir phase, and systolic pulmonary artery pressure were associated with AF development. In the regression analysis, we found that RAVi (OR: 3.1, 95% CI: 2.2‐6.3, P: .033) and RASr (OR: 0.82, 95% CI: 0.67‐0.93, P: .048) were independent predictors of AF development. Conclusions RA structure and functions are closely associated with AF development in the postoperative period, and screening of RA functions prior to surgery may be useful for preventing AF development.

Purpose High‐dose steroid therapy (HDST) has frequent side‐effects that appear at its cessation and depend on its dose. However, there is a lack of studies about the acute effects of HDST on cardiac function in adult patients. Methods We included in this study 30 patients who underwent HDST (intravenously at doses ranging from 250 to 1000 mg) and 30 healthy control subjects with similar demographic and clinical characteristics, between September and December 2016. Echocardiographic measurements were made before and during the first 3 hours after the end of treatment, and results were compared between patients and controls. Results There was no difference in baseline biochemical and echocardiographic characteristics between the patient and control groups. While left ventricular global longitudinal strain (LVGLS) and strain rate E were higher after treatment, no significant change was observed in conventional echocardiographic variables. Conclusions LVGLS, but not conventional echocardiographic variables, showed an increase in cardiac systolic function at the acute phase of HDST.

“…Independent predictors of right ventricular dysfunction in multivariate regression analysis However, in the presence of regional systolic dysfunction, global systolic function may not correctly reflect changes in ventricular function.TDI is a validated technique for quantitative evaluation of left ventricular functions, but its measurements are angle dependent and are affected by global heart movements, which is an important limitation10 While strain imaging shows the dimensional changes (deformations)…”

Purpose: Although it is affected at an early stage, there is a lack of studies investigating right ventricular (RV) function in patients with mitral stenosis (MS). We aimed to investigate the correlation between conventional echocardiographic variables and tricuspid annular plane systolic excursion (TAPSE), used as an indicator of RV dysfunction.Methods: We enrolled 59 consecutive patients with MS and assigned them in group 1 if TAPSE ≤16, or group 2 if: TAPSE >16.Results: The mean age of the patients was 42.2 ± 8 years, and 74.6% were females.In univariate analysis, maximal mitral valve gradient, mean mitral valve gradient, systolic pulmonary arterial pressure, RV strain, and RV strain rates were associated with RV dysfunction. In multivariate analysis, both strain variables were found to be independent predictors of RV dysfunction. Kaplan Maier survival analysis showed that patients with lower RV strain had more rehospitalization rate during the one-year follow-up period.Conclusions: RV dysfunction is common in patients with MS and is associated with higher rehospitalization rate and morbidity. Evaluation of RV strain and strain rate for early detection of RV dysfunction and prediction of rehospitalization may be an appropriate approach in mitral stenosis.
