Several studies show how patients with hyperoxia after cardiac arrest has increased mortality, but the association of hyperoxia before cardiac arrest and myocardial damage has never been investigated. Neither has the association between hyperoxia after cardiac arrest and myocardial injury. Our research hypothesis is that hyperoxia before cardiac arrest aggravates myocardial damage, secondly we wish to analyze the association between hyperoxia after cardiac arrest and myo...
This study aims to investigate the impact of antitachycardia pacing ( ATP) on the myocardial tissue with respect to its potential micro damage measured by several myocardial markers, especially by high-sensitive TroponinT.
The hypothesis is that single-shot imaging of myocardial infarction is possible in atrial fibrillation using MRI late enhancement technique
To evaluate whether ANP as an adjunctive therapy for AMI reduces myocardial infarct size and improves regional wall motion.
Despite major advances in the technical aspects of surgical repair of congenital heart diseases, perioperative myocardial damage with low cardiac output remains the most common cause of morbidity and death after repair of congenital heart lesions.
Reperfusion therapy in acute myocardial infarction saves viable myocardium, but paradoxically reestablishment of coronary artery flow also induces damage and cell death, decreasing the full benefit of reperfusion in terms of reduction of infarct size and preservation of ventricular function . Myocardial reperfusion can in itself produce more damage and cell death, this process defines the phenomenon of reperfusion injury, which could be prevented by applying additional therapie...
The purpose of this study is to evaluate the potential diagnostic and prognosis value of circulating microRNAs compared with cTnI for the patients of sepsis-induced myocardial injury at the emergency department (ED) and intensive care unit (ICU).
Besides contrast-induced acute kidney injury (CI-AKI), adscititious vital organ damage such as hypoxic liver injury (HLI) may affect the survival in patients with ST-elevation myocardial infarction (STEMI). Therefore, the investigator sought to evaluate the prognostic impact of CI-AKI and HLI in STEMI patients who underwent primary percutaneous coronary intervention (PCI).
To evaluate whether nicorandil as an adjunctive therapy for AMI reduces myocardial infarct size and improves regional wall motion
Study Objectives: To determine whether, in patients with large acute myocardial infarction undergoing primary or rescue angioplasty, the administration of subcutaneous Lenograstim [recombinant human Granulocyte-Colony Stimulating Factor (rhu G-CSF), Myelostim 34, Italfarmaco] associated with Myocardial Contrast Echocardiography and the intravenous infusion of sulphur hexafluoride (Sonovue, Bracco) determines an improvement: - in regional and global contractile function, my...
This study enrolled participants with documented exercise-induced myocardial ischemia in order to evaluate whether ranolazine, when taken prior to exercise, can improve blood flow to the heart (myocardial perfusion), as assessed by exercise-induced myocardial perfusion defect size (PDS) and total perfusion deficit (TPD), using gated single photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI). This was a 2-period crossover study. The last dose of each ...
Depression is commonly seen in patients with cardiovascular disorders. In recent studies it has been shown that mild to moderate depression symptoms were associated with increased likelihood of mental stress-induced myocardial ischemia (MSIMI), which is a risk factor of poor cardiac outcome. In this project, the investigators aim to assess the treatment of mental stress-induced myocardial ischemia in ischemic heart disease patients with mild to moderate depressive symptoms. T...
Prolonging infusions may decrease myocardial damage associated with bivalirudin use during primary PCI. The investigators hypothesized that continuing the bivalirudin infusion commenced during the procedure at the PCI recommended dose for 4 hours would prevent myocardial damage.
To perform a comprehensive evaluation of multidetector CT myocardial enhancement patterns in patients with an acute ST elevation MI. In particular we plan to assess the relationship between regions with early hypoperfusion and/or late hyperenhancement, and myocardial viability.
The aim is to examine the expression of αvβ3 integrin using a novel selective radiotracer in patients with myocardial infarction and investigate if it is a suitable tool for predicting myocardial recovery and thus prognosis.
To determine whether the administration of intravenous streptokinase (SK) early in the course of acute, transmural myocardial infarction would limit myocardial damage.
Coronary artery disease (CAD) remains the leading cause of death in the elderly. Silent myocardial ischemia (SI) is a manifestation of CAD in which there is a transient alteration in myocardial perfusion, function, and/or electrical activity not accompanied by chest pain. Mental and emotional stress, in particular hostility and anger are potent inducers of SI, Individuals with SI are at a 3-5 fold higher risk for the development of angina, myocardial infarction and death than s...
Acute myocardial infarction is a major cause of mortality and morbidity. Primary percutaneous coronary intervention (pPCI) is currently the most effective treatment strategy in acute myocardial infarction. However, a sizable number of patients fail to restore optimal myocardial reperfusion, mostly because of the 'no-reflow' phenomenon. Melatonin is the chief indoleamine produced by the pineal gland, and a well-known antioxidant and free radical scavenger. Several studies have s...
The purpose of this investigation is to compare subjects at high risk for silent myocardial ischemia in the placebo group to subjects at high risk for silent myocardial ischemia in the ranolazine group to determine if ranolazine can be used as a treatment to decrease silent myocardial ischemia (SMI). Subjects at high risk for silent myocardial ischemia are defined in this protocol as diabetics with stable ischemic heart disease. This study will look at the impact ranolazine tre...
ST-elevation myocardial infarction is a major cause of morbidity and mortality worldwide. ST-elevation myocardial infarction damages the regional myocardium that undergoes ischemia and necrosis, resulting in impairment of both systolic and diastolic functions of the heart. Left ventricular function and myocardial infarct size both serve as the main determinants Of patients' outcome after myocardial infarction. Timely management of ST-elevation myocardial infarction, using reper...
Glucagon-like peptide-1 (GLP-1), produced mainly in enteroendocrine cells, participates in energy homeostasis and glucose metabolism by regulating islet hormone secretion, gastrointestinal motility, and food intake, making GLP-1 agonist a treatment for diabetes and obesity. Pre-clinical and clinical studies have demonstrated that GLP-1 also has cardio-protection effects. GLP-1 agonists is able to improve markers of cardiac function, reduce myocardial infarct size and post-myoca...
This is a cross-sectional pilot study. The investigators seek to obtain early information pertaining to the relationship between measurements of myocardial perfusion reserve and myocardial fibrosis after receipt of Anthracycline-based chemotherapy (≥2 years prior).
Long-term beta-blocker therapy has not been investigated in contemporary randomized clinical trials in patients with myocardial infarction and normal heart function. The aim of this study is to determine whether long-term treatment with oral beta-blockade in patients with myocardial infarction and preserved left ventricular systolic ejection fraction reduces the composite of death of any cause or new myocardial infarction..
Recent clinical studies have shown that systemic therapeutic hypothermia improving the outcomes in patients with ST segment elevated myocardial infarction (STEMI) received primary percutaneous coronary intervention (P-PCI).Likewise, a few in vivo animal experiments have described the methods, mechanism and rationale of therapeutic hypothermia, including local myocardial hypothermia. However, little is known of the local myocardial hypothermia having impact on prognosis of the p...
The purpose of this study is to test whether injected medications will increase the amount of fat released by a fat cell. We will compare prednisolone (a synthetic cortisone) combined with isoproterenol (a drug given for asthma) versus using isoproterenol alone. We will also test if injections of isoproterenol and prednisolone will shrink the size of lipomas, which are benign fatty tumors.
