Many research groups are currently investigating new treatment modalities for myocardial infarction. Numerous aspects need to be considered for the clinical application of these therapies, such as low cell integration and engraftment rates of cell injection techniques. Decellularized tissues are considered good materials for promoting regeneration of traumatic tissues. The properties of the decellularized tissues are sustained after processing to powder form. In this study, we examined the use of decellularized tissue powder in a rat model of acute myocardial infarction. The decellularized tissue powders, especially liver powder, promoted cell integration and neovascularization both in vitro and in vivo. Decellularized liver powder induced neovascularization in the infarct area, resulting in the suppression of myocardial necrosis. The results of this study suggest that decellularized liver powder has good potential for application as a blood supply material for the treatment of myocardial infarction.

Regenerative cardiology has emerged as a novel strategy to improve cardiac healing following ischemic injury. While stem-cell-mediated cardiac regeneration has garnered much attention as a promising strategy, its value remains debated owing to the lack of ideal stem cell source candidates. Resident/endogenous cardiac-derived stromal cells (CSCs) exhibit superior therapeutic potential due to their innate abilities to differentiate into cardiac cells, especially cardiomyocytes (CM).

Background: Diabetic patients with ST-segment elevation myocardial infarction (STEMI) are at an increased risk of cardiovascular events as compared to non-diabetic patients. This analysis investigated outcomes of diabetic patients presenting with multivessel disease (MVD) and STEMI in a contemporary trial and the relevance of an immediate versus staged multivessel PCI strategy in this high-risk population.
Methods: Patients enrolled in the MULTISTARS AMI trial were stratified according to the presence/absence of diabetes.

Background: The protective function of the tetrandrine (TET)-mediated transient receptor potential vanilloid 2 (TRPV2) channel in myocardial ischemia/reperfusion injury (MI/RI) has been established in numerous investigations. The objective of the current study was to explain how TRPV2 further modulates downstream factors to influence the progression of MI/RI.
Methods: To this end, an MI/RI model in rats and a hypoxia-reoxygenation (H/R) cell model in H9c2 cells were constructed.

Background: The timely transfer of patients with ST-segment elevation myocardial infarction (STEMI) to percutaneous coronary intervention-capable centers is critical for improving outcomes. Although the American Heart Association recommends a door-in-door-out (DIDO) time of ≤30 minutes, national compliance remains low.
Project Rationale: At Harris Health, no patients with STEMI met this benchmark before 2022.

Background Hyperuricemia (HUA) frequently coexists with coronary artery disease (CAD) and is linked to adverse cardiovascular outcomes. The long-term impact of urate-lowering therapy (ULT) on clinical outcomes, including all-cause mortality and major adverse cardiovascular events (MACEs), in CAD patients after percutaneous coronary intervention (PCI) has not been determined. That was the aim of this study.
