Identification of Cardiometabolic Protein Biomarkers for Acute Myocardial Infarction Using Olink Proteomics.

Background: Acute myocardial infarction (AMI) is a critical cardiovascular event characterized by sudden coronary blood flow interruption, leading to myocardial ischemia and necrosis. Despite advances in acute therapeutic measures, understanding the metabolic damage related to AMI, particularly through specific protein expressions, remains limited. This study utilized Olink cardiovascular metabolomics technology to explore cardiovascular metabolism-related protein biomarkers associated with AMI, aiming to address the clinical need for early diagnosis and targeted therapy.

Modeling diabetic cardiomyopathy using human cardiac organoids: Effects of high glucose and lipid conditions.

Diabetic cardiomyopathy (DCM) is a complex metabolic disorder resulting from chronic hyperglycemia and lipid toxicity, which leads to cardiac dysfunction, fibrosis, inflammation, and mitochondrial impairment. Traditional two-dimensional (2D) cell cultures and animal models have limitations in replicating human cardiac physiology and pathophysiology. In this study, we successfully developed a three-dimensional (3D) model of DCM using cardiac organoids generated from human induced pluripotent stem cells (hiPSCs).
