BACKGROUND/AIMS: The imbalance of Treg/Th17 cells plays important role in the pathogenesis of dilated cardiomyopathy (DCM). Response gene to complement (RGC)-32 is a cell cycle regulator that plays an important role in cell proliferation. We evaluated whether the upregulation of RGC-32 was implicated in the homeostasis of Treg/Th17 cells in DCM. METHODS: The levels of plasma RGC-32, IL-17 and TGF-β1, and the frequencies of circulating CD4+ RGC-32+ T cells, Th17 and Treg cells in patients with DCM were determined by Cytokine-specific sandwich ELISA and the flow cytometer (FCM), respectively...

BACKGROUND AND OBJECTIVES: Dilated cardiomyopathy can be the end-stage of severe cardiac disorders and directly affects the cardiac muscle, inducing cardiomegaly and heart failure (HF). Although a wide variety of animal models are available to study dilated cardiomyopathy, there is no model to assess dilated cardiomyopathy with non-invasive, simple, and large screening methods. METHODS: We developed a dilated cardiomyopathy model in zebrafish larvae using short duration terfenadine, a known cardiotoxic drug that induces ventricular size dilation...

A 67-year-old man with dilated cardiomyopathy and renal insufficiency was admitted to our hospital with dyspnea secondary to end-stage heart failure. We introduced oxycodone for medically refractory dyspnea instead of morphine because of the patient's renal insufficiency. After the administration of oxycodone, his dyspnea was alleviated without any adverse opioid effects, such as respiratory depression. After treating his heart failure, he was able to leave the intensive care unit. Oxycodone may therefore be a reliable agent for the treatment of dyspnea in patients with end-stage heart failure and renal insufficiency...

The HeartWare HVAD is a small, third generation continuous flow pump that is intracorporeally placed for support of a failing ventricle in adult patients. This device is small in size when compared to other left ventricular assist devices and can therefore be used in smaller sized pediatric patients. We present our initial experience using the HVAD as a bridge to heart transplantation in the pediatric population. We performed a retrospective, single center, nonrandomized review of 17 pediatric patients who underwent HVAD implantation between June 2013 and March 2016...

Takotsubo cardiomyopathy (TTC) is characterized by transient systolic ventricular dysfunction. It is supposed to be caused by a cathecolaminergic wave which leads to myocardial stunning through a massive action on beta2-adrenoreceptor. Moreover, beta2-receptor hyperactivity negatively influences endothelial function. It can be detected by brachial flow mediated dilation (b-FMD) which assesses endothelium regulated vasomotility. The study aim is to analyze the b-FMD variability during hospitalization in 50 patients admitted with TTC...

We report the case of a man in his 60s who had dilated cardiomyopathy with severe functional mitral regurgitation. Four years after a cardiac resynchronization therapy (CRT) device with an implantable cardioverter defibrillator was implanted, this device was replaced with an adaptive CRT device because of battery consumption. Seven months after replacement of this device, the left ventricular pacing to right ventricular activation and the atrioventricular delay from automatic adjustments contributed to less functional mitral regurgitation...
