14. Astragaloside IV alleviates myocardial ischemia-reperfusion injury in rats through regulating PI3K/AKT/GSK-3β signaling pathways
Abstract Purpose: To investigate the effect of astragaloside IV (As-IV) on myocardial ischemia-reperfusion (I/R) injury in rats and reltaed mechanisms. Methods: Sixty rats were randomly divided into sham-operated, control I/R and 2.5, 5 and 10 mg/kg As-IV groups, 12 rats in each group. The later three groups were intragastrically administered with As-IV fo

15. Effect of Simulated Geomagnetic Activity on Myocardial Ischemia/Reperfusion Injury in Rats
Abstract Objective: To study the response of myocardial ischemia/reperfusion injury (MI/RI) in rats to simulated geomagnetic activity. Methods: In a simulated strong geomagnetic outbreak, the MI/RI rat models were radiated, and their area of myocardial infarction, hemodynamic parameters, creatine kinase (CK), lactate dehydrogenase (LDH), melatonin, and tro

16. Serum Sirtuin 1, 3 and 6 Levels in Acute Myocardial Infarction Patients
Resumo Fundamento: As sirtuínas podem atuar em muitos processos celulares, como a apoptose, reparo de DNA e metabolismo de lipídios e de glicose. Estudos experimentais sugeriram que alguns tipos de sirtuínas possam ter efeitos protetores contra disfunção endotelial, aterosclerose, hipertrofia cardíaca e lesão decorrente de reperfusão. Dados sobre a

17. Protective effect of crocetin from Crocus sativus L. on myocardial ischemia-reperfusion injury in rats
Abstract This study investigated the protective effect of crocetin from Crocus sativus L. on myocardial ischemia-reperfusion injury (MIRI) in rats. Sixty SD rats were randomly divided into sham-operated, model, and low-, medium- and high-dose crocetin groups. Later 3 groups were intragastrically administrated with 10, 20 and 40 mg/kg crocetin from Crocus sat

18. Pharmacological modulation of b-adrenoceptors as a new cardioprotective strategy for therapy of myocardial dysfunction induced by ischemia and reperfusion
Abstract Purpose: To evaluate the cardioprotective response of the pharmacological modulation of β-adrenergic receptors (β-AR) in animal model of cardiac ischemia and reperfusion (CIR), in spontaneously hypertensive (SHR) and normotensive (NWR) rats. Methods: CIR was induced by the occlusion of left anterior descendent coronary artery (10 min) and reper

19. Comparative Analysis between Transferred and Self-Referred STEMI Patients Undergoing Primary Angioplasty
Resumo Fundamento: Estudos mostram o benefício da terapia de reperfusão rápida no infarto agudo do miocárdio. No entanto, ainda ocorrem atrasos durante o transporte de pacientes para angioplastia primária. Objetivo: Definir se existe uma diferença no tempo total de isquemia entre pacientes transferidos de outro hospital comparados aos que procuram o

20. An Overview of Care Changes in the Last 6 Year in Primary PCI in ST-Elevation Myocardial Infarction in a Tertiary University Brazilian Hospital
Abstract Background: Although new studies and guidelines can be considered useful tools, it does not necessarily mean they are put into clinical practice. Objective: The aim of the current analysis was to assess the changes in primary percutaneous coronary intervention (PCI) and mortality in a tertiary university hospital in southern Brazil during a six-ye

21. C-reactive Protein is a Predictor of Mortality in ST-segment Elevation Acute Myocardial Infarction
Abstract Background: Inflammation is a major component of the response to tissue injury caused by myocardial infarction. High-sensitivity C-reactive protein (hs-CRP) levels might be a simple marker of the severity of this inflammatory response, providing prognostic information. Objective: To associate hs-CRP level on admission and other clinical characteri

22. Cardioprotective effect of preconditioning is more efficient than postconditioning in rats submitted to cardiac ischemia and reperfusion
Abstract Purpose: To investigate the cardioprotective effects of ischemic preconditioning (preIC) and postconditioning (postIC) in animal model of cardiac ischemia/reperfusion. Methods: Adult rats were submitted to protocol of cardiac ischemia/reperfusion (I/R) and randomized into three experimental groups: cardiac I/R (n=33), preCI + cardiac I/R (n=7) an

23. Acetaminophen Mitigates Myocardial Injury Induced by Lower Extremity Ischemia-Reperfusion in Rat Model
Abstract Objective: The injury-reducing effect of acetaminophen, an effective analgesic and antipyretic on ischemia-reperfusion continues to attract great attention. This study analyzed the protective effect of acetaminophen on myocardial injury induced by ischemia-reperfusion in an experimental animal model from lower extremity ischemia-reperfusion. Metho

24. Cardioprotective effect of lipstatin derivative orlistat on normotensive rats submitted to cardiac ischemia and reperfusion
Abstract Purpose: To evaluate in vivo animal model of cardiac ischemia/reperfusion the cardioprotective activity of pancreatic lipase inhibitor of the orlistat. Methods: Adult male Wistar rats were anesthetized, placed on mechanical ventilation and underwent surgery to induce cardiac I/R by obstructing left descending coronary artery followed by reperfusi
