BACKGROUND: This study aimed to evaluate the role of β-blocker therapy on modulating interleukin (IL)-33/ST2 (interleukin-1 receptor-like 1) signaling during ventricular remodeling related to heart failure (HF) after acute myocardial infarction (AMI). METHODS: Sprague-Dawley rats that survived surgery to induce AMI were randomly divided into the placebo group and the β-blocker treatment group. A sham group was used as a control. Left ventricular (LV) function variables, the myocardial infarct size, fibrosis and IL-33/ST2 protein expression was measured...

Myocyte apoptosis is a key determinant of cardiac recovery and prognosis of patients with acute myocardial infarction (AMI). Tumor necrosis factor (TNF)-like weak inducer of apoptosis (TWEAK), a member of TNF superfamily, is a pro-inflammatory and pro-angiogenic cytokine implicated in physiological tissue regeneration and wound repair and is closely related to cardiac remodeling, dysfunction and fibrosis. However, the role of TWEAK and its receptor Fn14 in the cardiomyocyte apoptosis is still poorly understood...

BACKGROUND: Despite large reductions in door-to-balloon times over the period, several studies from regional and national data showed that annual mortality rates were not decreased among patients who underwent primary percutaneous coronary intervention (PCI). However, these studies mostly focused on door-to-balloon time, and there was no consideration of total ischemic time in a trend of mortality. The aim of this study was to assess the annual trend between time to treatment and 1-month mortality among patients undergoing primary PCI...

ST-elevation myocardial infarction (STEMI), which constitutes nearly 25-40 % of current acute myocardial infarction (AMI) cases, is a medical emergency that requires prompt recognition and treatment. Since the 2013 STEMI practice guidelines, a wealth of additional data that may further advance optimal STEMI practices has emerged. These data highlight the importance of improving patient treatment and transport algorithms for STEMI from non-primary percutaneous coronary intervention (PCI) centers. In addition, a focus on the reduction of total pain-to-balloon (P2B) times rather than simply door-to-balloon (D2B) times may further improve outcomes after primary PCI for STEMI...

BACKGROUND: Paroxetine is a selective serotonin reuptake inhibitor utilized in the treatment of depression and anxiety disorders. Recent studies have identified paroxetine as a G protein-coupled receptor kinase-2 (GRK2) inhibitor capable of reversing cardiac dysfunction and remodeling in experimental models of acute myocardial infarction (AMI). We determine the clinical importance of paroxetine on cardiac functions in patients having AMI with depression (AMID) in comparison with fluoxetine, an unrelated selective serotonin reuptake inhibitor that does not inhibit GRK2...

AIMS: Naturally secreted nanovesicles known as exosomes are required for the regenerative effects of cardiosphere-derived cells (CDCs), and exosomes mimic the benefits of CDCs in rodents. Nevertheless, exosomes have not been studied in a translationally realistic large-animal model. We sought to optimize delivery and assess the efficacy of CDC-secreted exosomes in pig models of acute (AMI) and convalescent myocardial infarction (CMI). METHODS AND RESULTS: In AMI, pigs received human CDC exosomes (or vehicle) by intracoronary (IC) or open-chest intramyocardial (IM) delivery 30 min after reperfusion...

BACKGROUND: Despite aggressive pharmacotherapy and stenting, there is a residual risk of major adverse cardiovascular events among patients with acute coronary syndrome. High-density lipoprotein (HDL) has been a major target for secondary acute coronary syndrome prevention; however, a better understanding of the physiologic function of HDL has demonstrated that a high cholesterol efflux capacity, rather than high HDL concentrations alone, may be critical to improving outcomes. CSL112, a reconstituted, infusible human apolipoprotein A-I, has been demonstrated to increase cholesterol efflux capacity and to have a protective effect in experimental models of atherosclerotic cardiovascular disease...

: : We have previously demonstrated the cardioprotective effects of exosomes derived from mesenchymal stem cells (MSCs). It is well-known that the activation of Akt is involved in stem cell-induced cardioprotection. In the present study, we investigated whether exosomes released from Akt-overexpressing MSCs showed a beneficial effect on cardioprotection and angiogenesis. MSCs were collected from human umbilical cord (hucMSCs), and Akt was transfected into hucMSCs (Akt-hucMSCs) by using an adenovirus transfection system...

BACKGROUND/PURPOSE: TRB3 (tribbles 3), an apoptosis-regulated gene, increases during endoplasmic reticulum stress. Hypoxia can induce inflammatory mediators and apoptosis in cardiomyocytes. However, the expression of TRB3 in cardiomyocyte apoptosis under hypoxia is not thoroughly known. We investigated the regulation mechanism of TRB3 expression and apoptosis induced by hypoxia in cardiomyocytes. METHODS: An in vivo model of acute myocardial infarction (AMI) was applied in adult Wistar rats to induce myocardial hypoxia...
