There are about 425 million diabetes patients (20-79 years) in the world according to the International Diabetes Federation Diabetes Atlas - 8th Edition. The cardiovascular complication is one of the major causes of death in diabetes patients. Myocardial fibrosis is one of the serious pathological changes, so investigating the pathogenesis of myocardial fibrosis has the significant value. Our study aims to investigate the effect of Irbesartan (the angiotensin II receptor antagonist) on the changes of AGE-RAGE system and MMP family components, and analyzes the potential mechanisms in type 2 diabetes-induced myocardial fibrosis. Our results provide the theoretical base for better understanding the pathogenesis in type 2 diabetes-induced myocardial complication. It is useful for clinicians to select the effective therapeutic measures for treatment of type 2 diabetes-induced organ fibrosis.

Aims: Hypertrophic cardiomyopathy (HCM) is characterized by unexplained left ventricular hypertrophy (LVH) with key pathologic processes including myocardial necrosis, fibrosis, inflammation, and hypertrophy, which are involved in heart failure (HF), stroke, and even sudden death. Our aim was to explore the communication network among various cells in the heart of transverse aortic constriction (TAC) surgery induced HCM mice.
Materials And Methods: Single-cell RNA-seq data of GSE137167 was downloaded from the Gene Expression Omnibus (GEO) database.
Arrhythmogenic cardiomyopathy (ACM) is a genetic form of heart failure that affects 1 in 5000 people globally and is caused by mutations in cardiac desmosomal proteins including , and Individuals with ACM suffer from ventricular arrhythmias, sudden cardiac death, and heart failure. There are few effective treatments and heart transplantation remains the best option for many affected individuals. Here we performed single nucleus RNA sequencing (snRNAseq) and spatial transcriptomics on myocardial samples from patients with ACM and control donors.

Introduction: Heart failure with preserved ejection fraction (HFpEF) is a complex condition characterized by metabolic dysfunction and myocardial lipotoxicity. The roles of PTEN-induced kinase 1 (PINK1) and peroxiredoxin-2 (Prdx2) in HFpEF pathogenesis remain unclear.
Objective: This study aimed to investigate the interaction between PINK1 and Prdx2 to mitigate cardiac diastolic dysfunction in HFpEF.

Background: Dilated cardiomyopathy (DCM) is one of the most common causes of heart failure. Infiltration and alterations in non-cardiomyocytes of the human heart involve crucially in the occurrence of DCM and associated immunotherapeutic approaches.
Methods: We constructed a single-cell transcriptional atlas of DCM and normal patients.

To analyze the morphologic changes and the extent of severity in end-stage heart disease; and to explore the correlation with their clinical features. Twelve cases of recipients who underwent pediatric cardiac allograft transplantation were collected from May 2022 to November 2023 at the Seventh Medical Center of People's Liberation Army of China General Hospital. Gross pathologic examinations were performed and morphological changes were observed under a light microscope after HE, Masson's trichrome, and reticulin staining.
