Published: January 2023

Diabetes is a major risk factor for a variety of cardiovascular complications, while diabetic cardiomyopathy, a disease specific to the myocardium independent of vascular lesions, is an important causative factor for increased risk of heart failure and mortality in diabetic populations. Lysosomes have long been recognized as intracellular trash bags and recycling facilities. However, recent studies have revealed that lysosomes are sophisticated signaling hubs that play remarkably diverse roles in adapting cell metabolism to an ever-changing environment. Despite advances in our understanding of the physiological roles of lysosomes, the events leading to lysosomal dysfunction and how they relate to the overall pathophysiology of the diabetic heart remain unclear and are under intense investigation. In this review, we summarize recent advances regarding lysosomal injury and its roles in diabetic cardiomyopathy.

Right ventricular thrombus (RVT) is a rare but clinically significant condition associated with severe complications, such as pulmonary embolism and right heart failure. This case report presents a 68-year-old woman with a history of diabetes, coronary artery disease, and heart failure with reduced ejection fraction (HFrEF), who developed bilateral ventricular thrombi in the context of septic cardiomyopathy secondary to a diabetic foot infection and a urinary tract infection (UTI). Echocardiography revealed thrombi in both the right and left ventricles, severe global hypokinesia, and reduced ejection fraction.

IntroductionDiabetic cardiomyopathy (DCM) is a complication of diabetes mellitus (DM) that can lead to heart failure and increase the risk of mortality. Pedunculoside (PE), a novel triterpenoid saponin, exhibits anti-inflammatory and anti-oxidative stress (OS) properties. However, its role in DCM remains unexplored.

Background: Diabetes mellitus (DM) increases the risk of left ventricular dysfunction (LVD), which can progress to heart failure if undetected. Echocardiography, a non-invasive and cost-effective imaging tool, provides real-time assessment of left ventricular (LV) function and enables early detection of myocardial dysfunction using advanced techniques such as tissue Doppler imaging and strain analysis. Diabetic patients are particularly prone to LVD due to chronic hyperglycemia, insulin resistance, and systemic inflammation, leading to myocardial fibrosis, microvascular dysfunction, and oxidative stress.

Cardiovascular disease remains the leading cause of death in China, with its morbidity and mortality continue to rise. Ferroptosis, a unique form of iron-dependent cell death, plays a major role in many heart diseases. The classical mechanisms of ferroptosis include iron metabolism disorder, oxidative antioxidant imbalance and lipid peroxidation.

Background: With the increasing incidence of cancer among the adult population, radiotherapy (RT) is frequently used as a critical component in the treatment of various cancer types. Due to the nature of ionizing radiation, damage usually occurs within the tissues in anatomical neighborhood with the primary tumor localization. Dapagliflozin (DAPA), originally developed as an oral anti-diabetic medication, has been shown to have potent cardioprotective effects in the DAPA-HF trial.
