A female in her 80s with a history of cerebral infarction and atrial fibrillation had repeated hospitalizations because of heart failure caused by ischemic myocardiopathy. She lived alone and received home care and support for self-care with involvement of multiple providers, enabling early detection of disease exacerbation and subsequent intervention. A new ischemic event was managed with percutaneous coronary intervention. With deterioration of renal function, her response to diuretics decreased, and dialysis was initiated...

Doxorubicin (Dox) is an effective anti-cancer agent but limited by its cardiotoxicity, thus the search for pharmacological agents for enhancing anti-cancer activities and protecting against cardiotoxicity has been a subject of great interest. We have previously reported the synergistic anti-cancer effects of a novel compound DT-010. In the present study, we further investigated the cardioprotective effects of DT-010 in zebrafish embryos in vivo and the molecular underlying mechanisms in H9c2 cardiomyocytes in vitro...

BACKGROUND Takotsubo cardiomyopathy (TM), also called stress myocardiopathy or transient left ventricular apical ballooning syndrome, is characterized by acute left ventricular dysfunction with reversible wall motion abnormalities. TM resembles acute coronary syndrome (ACS) in the absence of coronary artery disease (CAD). In several reports, TM has been described in association with hyperthyroidism, suggesting the potential role of thyrotoxicosis in the pathophysiology. CASE REPORT We present the case of a 34-year-old man with TM associated with hyperthyroidism caused by Graves' disease...

Apolipoprotein O (ApoO) was recently observed in the cellular mitochondrial inner membrane, which plays a role in mitochondrial function and is associated with myocardiopathy. Empirical information on the physiological functions of apoO is therefore limited. In this study, we aimed to elucidate the effect of apoO on hepatic fatty acid metabolism. An adenoviral vector expressing hApoO was constructed and introduced into chow diet and high-fat diet induced mice and the L02 human hepatoma cell line. High levels of hApoO mRNA and protein were detected in the liver, and the expression of lipid metabolism genes was significantly altered compared with negative controls...

We investigated the effect of baoxin decoction (BXD) on myocardial fibrosis and clarified the possible mechanism of action. Dilated myocardiopathy was induced by doxorubicin injected intraperitoneally for 6 weeks. Rats that demonstrated dilated myocardiopathy were randomly divided into five groups plus a control group. Three groups were treated with BXD (7.5/kg, 15 g/kg and 30 g/kg) daily for 4 weeks. One group was treated with 8.75 g/kg of captopril (positive control), and with physiologic saline (negative control)...

BACKGROUND: Creatine phosphate (CrP) plays a fundamental physiological role by providing chemical energy for cell viability and activity, especially in muscle tissue. Numerous pathological conditions, caused by acute or chronic ischaemic situations, are related to its deficiency. For these reasons, it has been used as a cardioprotective agent in heart surgery and medical cardiology for many years. OBJECTIVE: This article gives a brief overview of the main characteristics of exogenous CrP...

BACKGROUND AND PURPOSE: Myocarditis is an inflammatory and autoimmune cardiovascular disease that causes dilated myocardiopathy and is responsible for high morbidity and mortality worldwide. Cortistatin is a neuropeptide produced by neurons and cells of the immune and vascular systems. Besides its action in locomotor activity and sleep, cortistatin inhibits inflammation in different experimental models of autoimmune diseases. However, its role in inflammatory cardiovascular disorders is unexplored...

To evaluate if morphological or functional abnormalities could be detected with echocardiography in hypertrophic myocardiopathy (HCM) mutation carriers without left ventricle (LV) hypertrophy has developed. HCM is caused by extensive genes mutations found in two-third of patients. Because screening for carriership of a large population is unreasonable, identification of asymptomatic subjects is confined to the use of imaging such as echocardiography, by which subtle abnormalities can be detected. Comprehensive echocardiographic studies including morphological and functional assessment were performed...

Despite of the fact that their clinical manifestations are similar, AL-amyloidosis (AL-A) and light chain deposition disease (LCDD) are individual nosological entities in view of considerable differences in their pathogenesis and pathomorphology. The paper describes a rare case of the concurrence of LCDD and AL-A in a patient with multiple myeloma. Clinically, there was dialysis-dependent renal failure, flail leg syndrome, myocardiopathy, and rhabdomyolysis. At the disease onset, his nephrobiopsy specimen could diagnose LCDD and myeloma or cast nephropathy...

Takotsubo cardiomyopathy, also known as transient left ventricular ballooning and stress myocardiopathy, has been diagnosed increasingly more over the last decade. The takotsubo syndrome mimics acute myocardial infarction in symptoms and in electrocardiographic findings. There are two major types of takotsubo cardiomyopathy: the classical type with left ventricular apical ballooning and a type with midventricular ballooning. Both types show different electrocardiographic patterns at presentation. The present article describes classical electrocardiographic findings of the acute and subacute phases of takotsubo cardiomyopathy...

Type 2 diabetes mellitus (T2DM) is considered an independent risk factor of heart failure (HF). It has been observed that diabetics have a higher risk of heart failure than non-diabetics. However, many aspects are still unknown; for example, the existence of a particular myocardiopathy common to T2DM, the pathogenesis of the HF associated with T2DM that is still not sufficiently clear, its role in the prognosis of HF, or the influence of anti-diabetic treatments on the outcome of the HF. An attempt is made in this review to summarise all those findings that have been published in the past 5 years as regards this interesting question, placing special emphasis on those questions still unresolved...

BACKGROUND: Excessive weight and obesity (EwO) are independent factors in the development of heart failure; they lead to a state of myocardiopathy via inflammatory and hormonal mechanisms. If excessively accumulated, epicardial fat favors a proinflammatory state. Ventricular asynchrony is a marker of heart failure progression and has been poorly studied in EwO. The objective was evaluate the relation between epicardial fat, body mass index (BMI) and mechanical synchrony measured by echocardiography, in healthy individuals with EwO...
