1. Effect of candesartan treatment on echocardiographic indices of cardiac remodeling in post-myocardial infarction patients
SUMMARY Objective: Myocardial infarction has unfavorable effect on structural and functional properties of the myocardium, referred to as cardiac remodeling. Left ventricular mass, left ventricular mass index, and relative wall thickness are important predictors of cardiac remodeling. In this study, we investigated the effect of candesartan treatment in com

2. MicroRNA-124a Protects the Myocardium Against Ischemia Reperfusion Injury Through Regulation of the Notch Signaling Pathway
Abstract Introduction: This study’s objective is to investigate the effect of downregulation of micro ribonucleic acid (miR)-124a on myocardial injury after ischemia reperfusion (I/R) in rats. Methods: Sprague Dawley (SD) rats (n=20) were divided into four groups - sham, I/R, I/R+miR-124a antagomir (I/R+ant-miR-124a), and I/R+ant-normal control (NC). The

3. Giant Epicardial Cyst Eroding Left Ventricular Wall Mimicking as Simple Pericardial Cyst
Abstract Epicardial cysts are rarer benign tumors than pericardial cysts. There have been few reports on surgical management of epicardial cysts. A 17-year-old normotensive boy presented with chest pain and palpitations, which on evaluation was found to be a mediastinal mass (pericardial cyst). Surgical resection of the cyst via thoracotomy was planned. The

4. The epicardial fat thickness is associated with fragmented QRS in patients with newly diagnosed metabolic syndrome
SUMMARY OBJECTIVE: The metabolic syndrome involves both metabolic and cardiovascular risk factors and is associated with cardiovascular mortality. Epicardial fat tissue plays a crucial role in deleterious effects of metabolic syndrome on the heart, including myocardial fibrosis. The fragmented QRS reflects heterogeneous depolarization of the myocardium and

5. Evaluation of Left Ventricular Systolic Function in Patients with Coronary Microvascular Dysfunction by Three-Dimensional Speckle-Tracking Imaging
Abstract Introduction: The objective of this study is to evaluate the left ventricular systolic function of patients with coronary microvascular dysfunction (CMD) using the three-dimensional speckle-tracking imaging (3D-STI) technique. Methods: From June 2018 to June 2019,72 subjects from Huzhou Central Hospital were enrolled, including 42 CMD in-patients

6. Blood mRNA Expression Profiles of Autophagy, Apoptosis, and Hypoxia Markers on Blood Cardioplegia and Custodiol Cardioplegia Groups
Abstract Introduction: Blood cardioplegia (BC) and Custodiol cardioplegia (CC) have been used for a long time in open heart surgery and are highly effective solutions. The most controversial issue among these two is whether there is any difference between them regarding myocardial damage after ischemia surgery. In this study, autophagy, apoptosis, and hypox

7. The Association between Tp-e interval, Tp-e/QT , and Tp-e/QTc Ratios and Coronary Artery Disease Spectrum and Syntax Score
Abstract Background Coronary artery disease (CAD) causes electrical heterogeneity on ventricular myocardium and ventricular arrhythmia due to myocardial ischemia linked to ventricular repolarization abnormalities. Objective Our aim is to investigate the impact of increased level of CAD spectrum and severity on ventricular repolarization via Tp-e interval

8. Assessment of left atrial function by strain in patients with acute ıschemic stroke left atrial function and acute stroke
SUMMARY OBJECTIVE: Myocardial speckle-tracking echocardiography can detect subtle abnormalities in the left atrial function. In this study, we aimed to investigate the relationship between left atrial myocardium and tissue function n assessed by two-dimensional speckle-tracking echocardiography and the National Institutes of Health Stroke Scale score in pa

9. Nuclear Medicine Methods for Assessment of Chronic Chagas Heart Disease
Abstract Several different imaging methods can be used to evaluate patients with Chagas heart disease (CHD) for diagnostic and prognostic purposes, including plain chest radiography; echocardiography; myocardial perfusion scintigraphy, for detection of ischemia and fibrosis; radionuclide gated-angiography, for evaluation of biventricular function; 123I-MIBG

10. After a STEMI, is Less Sugar more Protective to Myocardium?
Abstract Background: Vitiligo is a common skin disorder in which melanocytes are destroyed by auto-reactive immune responses. The loss of melanocytes results in the appearance of depigmented areas in different parts of the body. Cytokines have remarkable roles in the pathogenesis of vitiligo, such as IL-1, IL-6, and TNF-α; interleukin 27 (IL-27) is a new m

11. Batista Procedure with the Aid of Intraoperative Epicardial Echocardiography
Abstract Introduction: The number of cases for which the Batista procedure is indicated is small, but some patients with appropriate indication can achieve good therapeutic results. Objective: To avoid incorrect left ventricular incision and obtain good surgical results in patients with dilated cardiomyopathy suitable for partial left ventriculectomy, we e
