Wharton’s jelly mesenchymal stem cells (HWJMSCs) hold promise for myocardial regeneration, but optimal treatment regimen (preferably with a growth factor) is required to maximize functional benefits. The aim of this study was to explore the cardioprotective and angiogenesis effects of HWJMSCs combined with insulin-like growth factor-1 (IGF-1) in the treatment of acute myocardial infarction. Th...
Introduction: The aim of this study was to evaluate the effect of successful kidney transplantation (KT) on myocardial perfusion and left ventricular function by both qualitative (visual) interpretation and semiquantitative parameters, using myocardial perfusion scintigraphy with gated-single photon emission computed tomography (gated-SPECT) in patients suffering from end-stage renal disease. ...
background : kernel smoothing method is a non-parametric or graphical method for statistical estimation. in the present study was used a kernel smoothing method for finding the death hazard rates of patients with acute myocardial infarction. methods : by employing non-parametric regression methods, the curve estimation, may have some complexity. in this article, four indices of epanechnikov, b...
Background and objectives: Clinical manifestations of coronary artery disease such as myocardial infarction generally have onset from middle age onwards. However, studies indicate that the atherosclerotic process begins to develop during childhood. The purpose of this study was to evaluate the frequency of risk factors for atherosclerosis in children with family history of premature myocardial ...
According to recent researches about the importance of prognostic value of QT dispersion (QTD) in patients with acute myocardial infarction , the present study was performed to assess the relationship between QT dispersion increment and incidence of ventricular fibrillation in patients with acute myocardial infarction. &nb...
Technetium-99m-pyrophosphate (99mTc-PYP) has been used, in combination with thallium-201, to estimate the site and extent of myocardial infarcts. We report a case of acute myocardial infarction with severe coronary disease in which the distribution of 99mTc-PYP was extensive. A 78-year-old man presented with dyspnea, and a diagnosis of non-ST-segment elevation acute myocar...
Background: It is assumed giving oxygen to patients with acute myocardial infraction may increase the oxygenation of the ischemic tissue; however, the usefulness of oxygen in these patients has become a challenging topic. Thus, the present study aimed to determine the effect of oxygen inhalation on cardiac biomarkers in patients with acute myocardial infarction. Methods: This randomized cli...
Stent thrombosis as a complication of percutaneous coronary intervention frequently is associated with deadly events such as myocardial infarction and sudden death. Definitions of stent thrombosis have not been in a uniform manner in different clinical studies. Two episodes of acute ST elevation myocardial infarction nearly two years after implanting a drug – eluting stent in a 58-year-...
Tc-99m-MIBI is an isonrtrile derivative used for evaluation of myocardial perfusion in recent years. In this preliminary report, 7 patients with coronary artery disease are evaluated with Tc-99m-MlBl stress planar and sped studies. Good correlation with coronary angiography is observed in these cases. In view of inherent technical problems present with thallium 201, Tc-99m-MIBi is a good ...
Besides its severe neurological injuries, spontaneous subarachnoid hemorrhage (SAH) commonly causes cardiac complications. These complications could include three different aspects of cardiac diseases, that is, electrocardiographic abnormalities, myocardial injuries, and left ventricular dysfunction. These complications not only may lead to misdiagnosis of SAH as myocardial infarction, but also...
