Summary: The study suggests that the phosphorylation of sarcomeric proteins is associated with heart failure with preserved ejection fraction, and treatment with cardiosphere-derived cells can partially reverse this process, with PKC beta identified as a potential therapeutic target in HFpEF.

Summary: This study summarized the differences between pediatric diastolic heart failure and systolic heart failure in terms of primary causes, clinical features, and short-term prognosis. B-type natriuretic peptide has limited diagnostic value in pediatric DHF. Diastolic function indicators significantly improved after treatment in DHF patients.

Summary: This study investigated the effects of coronary risk factors on left ventricular size and cardiac function using structure equation modeling. It found that each risk factor directly affected the shape of the heart. Managing risk factors is crucial in reducing the heart failure pandemic, as vascular risk and heart failure risk are likely to evolve simultaneously.

Summary: Pathological remodeling of the heart in chronic heart failure is linked to structural changes perpetuated by cardiac fibroblasts, with GRK5 playing a key role in regulating fibroblast activation and cardiac fibrosis. GRK5 inhibition shows potential beneficial effects in cardiac disease by preventing fibroblast activation and reducing fibrosis and hypertrophy.

Summary: This study suggests that mitochondrial oxidative stress contributes to diastolic dysfunction by causing mitochondrial dysfunction, impaired mitochondrial dynamics, increased synthesis of pro-inflammatory and pro-fibrotic cytokines, activation of fibroblasts, and the accumulation of extracellular matrix, resulting in interstitial fibrosis and passive stiffness of the myocardium.

Summary: Hypertensive heart disease is a significant cause of heart failure and its prevalence has been increasing despite improvements in hypertension treatment. The prevention of heart failure in patients with hypertensive heart disease is an important unmet medical need. This article proposes a new perspective that focuses on the detection and reversal of histological changes in the hypertensive heart, particularly myocardial interstitial fibrosis.

Summary: In this study, patients with heart failure with preserved ejection fraction (HFpEF) were stratified based on left ventricular ejection fraction (LVEF), resulting in distinct morphologic and pathophysiologic subphenotypes. Patients with LVEF ranging from 50% to 60% demonstrated reduced contractility, impaired ventriculo-arterial coupling, and higher extracellular volume fraction, while patients with LVEF >60% exhibited a hypercontractile state with excessive left ventricular afterload and diminished preload reserve.

Summary: The study assessed the impact of the 2016 ASE/EACVI updated algorithm on the assessment of diastolic function in real-world clinical practice. Significant differences were found in the evaluation results based on different guidelines, especially in reclassifying mild diastolic dysfunction to normal diastolic function.

Summary: Chronic infusion of a beta 3-adrenergic receptor agonist attenuates cardiac fibrosis and improves diastolic dysfunction independently of blood pressure in an angiotensin II-induced hypertensive mouse model. This drug might be an effective treatment of heart failure with preserved ejection fraction.

Summary: This study found no significant difference in ambulatory blood pressure reductions between renal denervation and a sham procedure in treated patients with resistant hypertension. Although the blood pressure reduction after renal denervation was similar to other sham-controlled studies, the unexpected greater reduction in the sham control group in this study highlights design issues that will be addressed in a new trial.

Summary: This study investigated the prognostic significance of combining intra-aortic balloon pumping (IABP) with extracorporeal membrane oxygenation (ECMO) for acute myocardial infarction (AMI) patients. The results showed that the addition of IABP support to ECMO was associated with a reduced risk of short-term mortality, but an increased risk of major bleeding.

Summary: Ossification of the posterior longitudinal ligament (OPLL), a disease characterized by ectopic ossification of a spinal ligament, can lead to neurological disorders. This study investigated the role of hydroxyacid oxidase 1 (Hao1) in OPLL development and found that Hao1 expression decreased during osteoblast differentiation. Further experiments using Hao1-deficient mice showed that Hao1 loss did not promote ectopic ossification, but rather regulated the tricarboxylic acid (TCA) cycle metabolism.

Summary: This study investigates the morphological characteristics and association with serum cytokine levels of de novo and donor-transmitted plaques in patients with coronary allograft vasculopathy within one year after heart transplantation. The results indicate that fibrous proliferation contributes to the progression of these plaques, and baseline serum interleukin-31 levels may contribute to intimal fibrous proliferation.

Summary: This retrospective cohort study examined the association of early use of SGLT2 inhibitors with outcomes in hospitalized patients with acute coronary syndrome. The results showed that SGLT2 inhibitors were associated with a lower risk of the primary outcome in patients with severe heart failure, but not in patients without severe heart failure.

Summary: High-throughput metabolomics has facilitated large-scale cohort studies. Long-term studies require multiple batch-based measurements, which necessitates sophisticated quality control to eliminate bias. In this study, liquid chromatography-mass spectrometry was used to analyze 10,833 samples in 279 batch measurements. The quantified profile included 147 lipids. Normalization using QC samples reduced the coefficient of variation for the lipids. This study provides unbiased and quantified data for large-scale metabolomics.
