Article Abstract
Autonomic nervous dysfunction is a known cardiac sequalae in patients with end-stage liver disease and is associated with a poor prognosis. Heart rate analysis using nonlinear models such as multiscale entropy (MSE) or complexity may identify marked changes in these patients where conventional heart rate variability (HRV) measurements do not. To investigate the application of heart rate complexity (HRC) based on MSE in liver transplantation settings. Thirty adult recipients of elective living donor liver transplantation were enrolled. HRV parameters using conventional HRV analysis and HRC analysis were obtained at the following time points: (1) 1 day before surgery, (2) postoperative day (POD) 7, (3) POD 14, (4) POD 90, and (5) POD 180. Preoperatively, patients with MELD score ≥ 25 had significantly lower HRC compared to patients with lower MELD scores. This difference in HRC disappeared by POD 7 following liver transplantation and subsequent analyses at POD 90 and 180 continued to show no significant difference. Our results indicated a significant negative correlation between HRC based on MSE analysis and liver disease severity preoperatively, which may be more sensitive than conventional linear HRV analysis. HRC in patients with MELD score ≧ 25 improved over time and became comparable to those with MELD < 25 as early as in 7 days.

Mitral regurgitation is the most common valve disease worldwide. Despite its wide success in inoperable or high-risk surgical patients, transcatheter edge-to-edge repair remains limited by some anatomic features and the not negligible rate of significant residual regurgitation. Transcatheter mitral valve replacement has emerged as a viable alternative that promises to overcome these issues, but its development has been progressing slowly.

Introduction: People with rheumatic and musculoskeletal diseases are advised to do aerobic exercise for symptom relief and to reduce the risk of cardiovascular disease. Continuous exercise at an intensity causing a rate of perceived exertion of 15, on a 6-20-point Borg scale, exemplifies such exercise. Also, the instruction "Now you need to increase your heart rate" is used before aerobic exercise.

Unlabelled: Aortic dissection is a life-threatening cardiovascular emergency, particularly Stanford type A, which typically necessitates urgent surgical intervention. Despite advances in surgical techniques and perioperative care, preoperative bleeding and coagulopathy remain significant challenges. Tranexamic acid, an antifibrinolytic agent, is widely used to minimize perioperative bleeding in cardiovascular surgeries; however, its role in the non-surgical, preoperative stabilization of aortic dissection has not been well established.

Introduction: Pulmonary embolism (PE) is a life-threatening condition with well-defined management strategies; however, the presence of a clot-in-transit (CIT)-a mobile thrombus within the right heart-introduces a uniquely high-risk scenario associated with a significantly elevated mortality rate. While several therapeutic approaches are available-including anticoagulation, systemic thrombolysis, surgical embolectomy, and catheter-directed therapies-there is no established consensus on a superior treatment modality. Catheter-based mechanical thrombectomy has emerged as a promising, minimally invasive alternative that mitigates the bleeding risks of systemic thrombolysis and the invasiveness of surgery.

Background: The objective of this study was to compare the effects of daily consumption of white potatoes compared with white rice on cardiometabolic health in individuals with type-2 diabetes (T2D).
Objective: To determine the effects of white potato consumption compared to white rice (a commonly consumed refined grain) on indices of glycemic control and cardiovascular health in individuals with overweight or obesity and T2D.
Methods: In this randomized crossover study, comparative control trial, 24 adults with T2D [45-80 y, body mass index (kg/m) 25-40] consumed baked white potatoes (100 g) or calorie-matched white rice (75 g) daily for 12 wk, separated by a 2-wk washout, with assessments of glycemic control, lipids, inflammation, blood pressure, endothelial function, and body composition at baseline (only 1 baseline visit included as a covariate in statistical analyses), 6 wk, and 12 wk.
