Deletion 1p36 syndrome is recognized as the most common terminal deletion syndrome. Here, we describe the loss of a gene within the deletion that is responsible for the cardiomyopathy associated with monosomy 1p36, and we confirm its role in nonsyndromic left ventricular noncompaction cardiomyopathy (LVNC) and dilated cardiomyopathy (DCM). With our own data and publically available data from ar...
OBJECTIVE Mutations in the LMNA gene encoding lamins A and C of the nuclear lamina are a frequent cause of cardiomyopathy accounting for 5-8% of familial dilated cardiomyopathy (DCM). Our aim was to study disease onset, presentation and progression among LMNA mutation carriers. METHODS Clinical follow-up data from 27 LMNA mutation carriers and 78 patients with idiopathic DCM without an LMNA m...
Myocardial hibernation (MH) is a well-known feature of human ischaemic cardiomyopathy (ICM), whereas its presence in human idiopathic dilated cardiomyopathy (DCM) is still controversial. We investigated the histological and molecular features of MH in left ventricle (LV) regions of failing DCM or ICM hearts. We examined failing hearts from DCM (n = 11; 41.9 ± 5.45 years; left ventricle-ejection...
Background: Dilated cardiomyopathy is one of the important causes of congestive heart failure and attributes to 25% of all cases of CHF. Moreover, in majority of cases with DCM, no specific etiology is known. The increasing incidence of DCM is also associated with significant morbidity and mortality. So, the current study aimed at understanding the electrocardiographic and echocardiographic pro...
Five patients with only mildly dilated ventricles but other features typical of congestive cardiomyopathy underwent cardiac transplantation for class IV NYHA heart failure. The findings of clinical studies, cardiac catheterization, endomyocardial biopsy, and pathologic examination of the removed hearts in this group with mildly dilated congestive cardiomyopathy (MDCM) were compared with similar...
BACKGROUND Diabetic cardiomyopathy (DCM) is an increasingly recognized cause of chronic heart failure amongst diabetic patients. Both increased reactive oxygen species (ROS) generation and impaired ROS scavenging have been implicated in the pathogenesis of hyperglycemia-induced left ventricular dysfunction, cardiac fibrosis, apoptosis and hypertrophy. We hypothesized that 3',4'-dihydroxyflavono...
Neuregulin-1 (NRG-1) is a cardioactive growth factor released from endothelial cells. However, the effect of NRG-1 on ventricular remodeling in diabetic cardiomyopathy (DCM) remains unclear. The aim of the present study was to investigate the pathophysiological role of NRG-1 in a rat model of DCM. Rat cardiac microvascular endothelial cells (CMECs) were transfected with human NRG-1 (hNRG-1) len...
In this study, we mainly investigated the effects of Shengmai San (SMS) on diabetic cardiomyopathy (DCM) in db/db mice. The db/db mice were randomly divided into model group and SMS group, while C57BLKS/J inbred mice were used as controls. After 24-week treatment, blood glucose, body weight, and heart weight were determined. Hemodynamic changes in the left ventricle were measured using catheter...
Hyperglycemia is a well-characterized contributing factor for cardiac dysfunction and heart failure among diabetic patients. Apoptosis of cardiomyocytes plays a major role during the onset and pathogenesis of diabetic cardiomyopathy (DCM). Nonetheless, the molecular machinery underlying hyperglycemia-induced cardiac damage and cell death remains elusive. In the present study, we found that chlo...
Cardiac metabolism is deranged in dilated cardiomyopathy (DCM). Phosphorus-31 (P) and hydrogen1 (H) magnetic resonance spectroscopy (MRS) allow for the non-invasive assessment of various aspects of cardiac metabolism, showing deranged cardiac energetics and lipid accumulation in DCM. In the future, MRS may become an important biomarker tool for monitoring the effects of novel heart-failure trea...
