Background: Heart failure with preserved ejection fraction (HFpEF) is a syndrome in which patients have symptoms and signs of heart failure but preserved ejection fraction. Left atrial (LA) volume and function are known to be impaired in these patients. Two-dimensional speckle-tracking echocardiography (2D-STE) has recently enabled the quantification of LA deformation dynamics. In this study, we evaluated the use of 2D-STE for the diagnosis of HFpEF.
Patients And Methods: The study included 83 patients with suspected HFpEF. Patients were divided into two groups after HFpEF had been diagnosed according to current guidelines. Parameters of diastolic dysfunction were evaluated, including left ventricular mass index (LVMI), LA volume index (LAVI), E/A ratio, deceleration time (DT), E/E', and STE parameters such as global longitudinal LA strain during ventricular systole (GLAs-res) and strain during late diastole (GLAs-pump).
Results: The values of BNP, LVMI, DT, LAVI, and GLAs-res were significantly different between the two groups. In univariate analysis, a strong negative correlation was seen between GLAs-res and BNP (r = -0.567, p < 0.001) as well as between GLAs-res and DT (r = -0.665, p < 0.001), while a moderate negative correlation was found between GLAs-res and LVMI (r = -0.458, p < 0.001) and GLAs-res and LAVI (r = -0.316, p = 0.004). In logistic regression analysis, GLAs-res (p = 0.049, OR = 0.71, 95 % CI = 0.451-0.99), BNP (p = 0.025, OR = 1.08, 95 % CI = 1.01-1.14), and LAVI (p = 0.042, OR = 1.59, 95 % CI = 1.02-2.48) were found to be independent predictors of HFpEF.
Conclusion: LA function as assessed by 2D-STE is impaired in patients with HFpEF. A GLAs-res value of < 17.5 % can be useful for the diagnosis of HFpEF.

Background: Anti-CD19 chimeric antigen receptor (CAR) T cell therapy is a common, yet highly efficient, cellular immunotherapy for lymphoma. However, many recent studies have reported on its cardiovascular (CV) toxicity. This study analyzes the cardiotoxicity of CD19 CAR T cell therapy in the treatment of lymphoma for providing a more valuable reference for clinicians.

Introduction: Hypertension is among the most significant non-communicable public health issues worldwide. High blood pressure, or hypertension, has been associated with severe health consequences, including death, aneurysms, stroke, chronic renal disease, eye damage, heart attack, heart failure, peripheral artery disease, and vascular dementia. Consequently, this study aimed to investigate the predictors linked to survival time and the progression of blood pressure measurements in hypertensive patients.

Sorting nexins (SNXs) as the key regulators of sorting cargo proteins are involved in diverse diseases. SNXs can form the specific reverse vesicle transport complex (SNXs-retromer) with vacuolar protein sortings (VPSs) to sort and modulate recovery and degradation of cargo proteins. Our previous study has shown that SNX3-retromer promotes both STAT3 activation and nuclear translocation in cardiomyocytes, suggesting that SNX3 might be a critical regulator in the heart.

Introduction: Real-life data on the long-term use of a maintenance immunosuppressive protocol in heart transplant patients using delayed Everolimus + Tacrolimus are scarce.
Methods: This is a retrospective study that included all heart transplant patients from 2011 to 2021 in two Spanish hospitals. In Hospital A, the preferred immunosuppressive strategy included Everolimus initiation at 2 months post-transplant combined with Tacrolimus and was compared with the results of Hospital B, where a standard Tacrolimus and Mycophenolate mofetil protocol was used.

Aims: Hypoalbuminemia is frequently found in patients with heart failure (HF), associated with higher morbimortality in acute HF (AHF). Moreover, Carbohydrate Antigen 125 (CA125) is elevated in most of the AHF patients. In this cohort of patients admitted for AHF, our objective was to evaluate the association between hypoalbuminemia and long-term outcomes, including mortality and HF readmissions, stratified by CA125 concentration.
