Inflammatory responses and lipid metabolism disorders are key components in the development of coronary artery disease and contribute to no-reflow after coronary intervention. This study aimed to investigate the association between the neutrophil to high-density lipoprotein ratio (NHR) and no-reflow phenomenon in ST-segment elevation myocardial infarction (STEMI) patients after primary percutaneous coronary intervention (PPCI). This study enrolled 288 patients with STEMI from September 1st, 2022 to February 29th, 2024, in the Zhengzhou Central Hospital Affiliated to Zhengzhou University.

Electrical stimulation of existing three-dimensional bioprinted tissues to alter tissue activities is typically associated with wired delivery, invasive electrode placement, and potential cell damage, minimizing its efficacy in cardiac modulation. Here, we report an optoelectronically active scaffold based on printed gelatin methacryloyl embedded with micro-solar cells, seeded with cardiomyocytes to form light-stimulable tissues. This enables untethered, noninvasive, and damage-free optoelectronic stimulation-induced modulation of cardiac beating behaviors without needing wires or genetic modifications to the tissue solely with light.

The clinical application of doxorubicin (DOX) is limited due to its cardiotoxicity, which is primarily attributed to its interaction with iron in mitochondria, leading to lipid peroxidation and myocardial ferroptosis. This study aimed to investigate the role of the gut microbiota-derived metabolite, indole-3-lactic acid (ILA), in mitigating DOX-induced cardiotoxicity (DIC). Cardiac function, pathological changes, and myocardial ferroptosis were assessed in vivo.

Coronary microvascular dysfunction (CMD) refers to clinical symptoms caused by structural and functional damage to coronary microcirculation. The timely and precise diagnosis of CMD-related myocardial ischemia is essential for improving patient prognosis. This study describes a method for the multimodal (fluorescence, ultrasonic, and photoacoustic) noninvasive imaging and treatment of CMD based on ischemic myocardium-targeting peptide (IMTP)-guided nanobubbles functionalized with indocyanine green (IMTP/ICG NBs) and characterizes their basic characteristics and in vitro imaging and targeting abilities.

Purpose: This study explores the effects of anthracycline chemotherapy (AC) on breast cancer patients, focusing on changes in body composition, advanced echocardiographic parameters at rest and during exercise, and biomarkers; and subsequently assesses whether these parameters are associated with impaired cardiorespiratory fitness (CRF).
Methods: In this prospective study, we evaluated women with early-stage breast cancer undergoing AC at three visits: before AC, 1 month after, and 6 months post-AC.
Results: The study included 32 women with breast cancer, with functional disability increasing from 9.
