1. Immunoadsorption therapy in refractory heart failure patients with dilated cardiomyopathy: a potential therapeutic option
SUMMARY OBJECTIVE: Removal of cardiac autoantibodies by immunoadsorption might confer clinical improvement in dilated cardiomyopathy. In this pilot study, we investigated the efficacy and safety of immunoadsorption therapy in refractory heart failure patients with dilated cardiomyopathy. METHODS: This study consisted of 9 heart failure patients with dilate

2. Predictive value of oxidative, antioxidative, and inflammatory status for left ventricular systolic recovery after percutaneous coronary intervention for ST-segment elevation myocardial infarction
SUMMARY OBJECTIVE: This study aimed to evaluate the association between left ventricular ejection fraction recovery and the total oxidant status, total antioxidant capacity, and high-sensitivity C-reactive protein levels. METHODS: A total of 264 ST-elevation myocardial infarction patients were classified into two groups according to baseline and 6-month fo

3. Predictors of left ventricular ejection function decline in young patients with ST-segment elevation myocardial infarction
SUMMARY OBJECTIVE: A decrease in the left ventricular ejection fraction (≤40%) in the setting of ST-segment elevation myocardial infarction is a significant predictor of mortality in the young ST-segment elevation myocardial infarction population. In this study, we aimed to investigate the predictors of left ventricular ejection fraction reduction and eva

4. Preoperative Left Ventricular Global Longitudinal Strain Identifies Aortic Stenosis Patients with Improved Postoperative Recovery of Left Ventricular Geometry: A Prospective Cohort Study
Abstract Introduction: The left ventricular ejection fraction (LVEF) is commonly used as a marker of aortic stenosis (AS) disease severity and to indicate surgical intervention. However, an LVEF <50% identifies mainly advanced disease. Hence, earlier detection of subclinical LV systolic dysfunction may improve clinical decision-making. The global longitudin

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. Proadrenomedullin in Patients with Preserved Left Ventricular Systolic Function Undergoing Coronary Artery Bypass Grafting
Abstract Introduction: A potentially new marker of cardiovascular diseases — proadrenomedullin is the precursor of adrenomedullin, which is a multifunctional peptide hormone, produced in most of the tissues in response to cellular stress, ischemia, and hypoxia. Methods: Ninety-three people, aged 51-79 years, were included in the study. Exclusion criteria

7. Cardiac Surgery-associated Acute Kidney Injury in Patients with Preserved Baseline Renal Function
ABSTRACT Introduction: Cardiac surgery-associated acute kidney injury (CSA-AKI) is a powerful predictor of perioperative outcomes. We evaluated the burden of CSA-AKI in patients with preserved baseline renal function. Methods: The data of 2,162 adult patients who underwent cardiac surgery from January 2005 to December 2020 were analyzed. Logistic regressio

8. Physical Training Improves Cardiac Structure and Function of Rats After Doxorubicin-Induced Cardiomyopathy
Abstract Background: The use of doxorubicin in chemotherapy has been associated with cardiotoxicity and heart failure. Physical exercise produces favorable morphofunctional adaptations in the cardiovascular system and may reverse cardiac dysfunction in patients undergoing chemotherapy. Objective: To assess the effects of physical training on myocardial str

9. Effects of Exercise Training on Left Ventricular Diastolic Function Markers in Patients with Obstructive Sleep Apnea: A Randomized Study
Abstract Background Exercise training (ET) is an adjunctive treatment for obstructive sleep apnea (OSA) and its consequences. However, the effects of exercise on heart remodeling are unknown in the population with OSA. Objective We investigated the effect of ET on markers of diastolic function, sleep parameters, and functional capacity in patients with O

10. Minimal Invasive Thoracoscopic Mitral Valve Surgery
ABSTRACT Introduction: The totally thoracoscopic approach for mitral valve (MV) disease is a minimally invasive method. We investigated the procedure’s feasibility, safety and effectiveness when it was performed by an experienced operator. Methods: We retrospectively analysed 96 consecutive patients with MV disease treated between March 2016 and November

11. 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

12. Iatrogenic Complications During the Diagnostic Work-Up of an Inflammatory Cardiomyopathy
Abstract A 72-year-old woman was admitted for acute heart failure. The echocardiography revealed moderate depression of the left ventricular ejection fraction. Coronary disease was excluded by coronarography. Cardiac magnetic resonance showed predominantly left ventricular septal hypertrophy and severe depression of the left ventricular systolic function.
