BACKGROUND: There is still insufficient knowledge on the potential effect of mild to moderate sleep-disordered breathing (SDB) that is widely prevalent, often asymptomatic, and largely undiagnosed in patients with stable coronary artery disease (CAD). SDB affects 34% of men and 17% of women aged between 30 and 70. The objective of this study was to evaluate the association between SDB and left ventricular (LV) hypertrophy as well as structural remodeling in stable CAD patients. METHODS: The study was based on a cross-sectional design...

Cardiac injury, including hypertrophy and fibrosis, induced by advanced glycation end products (AGEs) has an important function in the onset and development of diabetic cardiomyopathy. Profilin‑1, a ubiquitously expressed and multifunctional actin‑binding protein, has been reported to be an important mediator in cardiac hypertrophy and fibrosis. However, whether profilin‑1 is involved in AGE‑induced cardiac hypertrophy and fibrosis remains to be determined. Therefore, the present study aimed to investigate the function of profilin‑1 in cardiac injury induced by AGEs...

Previous studies have shown that inflammatory process contributes to the pathogenesis of cardiac damage induced by diabetes mellitus. However, the underlying mechanisms and strategies to alleviate inflammatory injury in the diabetic heart are not fully elucidated. In this study, we investigated the potential role and related mechanism of bamboo leaf extract (BLE) on diabetes-induced cardiac fibrosis in rats. Diabetes was induced by streptozocin (STZ) in rats, blood glucose and glycosylated hemoglobin A1c (HbAlc) were measured...

Exercise training has been demonstrated to have beneficial effects in patients with heart failure (HF) or diabetes. However, it is unknown whether diabetic patients with HF will benefit from exercise training. Male Wistar rats were fed either a standard (Sham, n= 53) or high-fat, high-sucrose (HFHS) diet (D, n=66) for 6 months. After 2 months of diet, the rats were already diabetic. Rats were then randomly subjected to either myocardial infarction by coronary artery ligation (MI) or sham operation (Sham). Two months later, heart failure was documented by echocardiography and animals were randomly subjected to exercise training with treadmill for eight additional weeks or remained sedentary...

BACKGROUND Epicardial adipose tissue (EAT) is recognized as a useful indicator for type 2 diabetes mellitus (T2DM) and obesity. However, studies on the association between vitamin D status and EAT thickness in type 2 diabetes (T2D) are limited. In this study, we aimed to evaluate the association of vitamin D (Calcifediol) status and EAT thickness (EATT) in Chinese non-obese patients with T2D. MATERIAL AND METHODS A cross-sectional study was performed among 167 non-obese T2D Chinese patients and 82 non-diabetic patients, who are age- and gender-matched during the winter months...

BACKGROUND: Traditional cardiovascular risk stratification tools that employ clinical risk factors are limited by their modest discriminative abilities. As such, robust cardiovascular risk assessment, including our understanding of the complex interplay between risk factors, in the primary preventive setting, remains incomplete. Phenotypical heterogeneity may be even greater among subjects with hyperglycemic conditions, i.e., prediabetes and diabetes, which is worrisome, given the dramatic global rise in mean fasting glucose levels, and the strong association with adverse cardiovascular outcomes...

BACKGROUND: Type 1 diabetes mellitus (DM) patients surviving myocardial infarction (MI) have substantially higher cardiovascular morbidity and mortality compared to their non-diabetic counterparts owing to the more frequent development of subsequent heart failure (HF). Neuregulin (NRG)-1β is released from cardiac microvascular endothelial cells and acts as a paracrine factor via the ErbB family of tyrosine kinase receptors expressed in cardiac myocytes to regulate cardiac development and stress responses...

BACKGROUND: Epicardial adipose tissue (EAT) is the ectopic visceral fat surrounding the heart, which plays an important role in atherosclerosis of the coronary arteries via endothelial damage. Several studies have also suggested that vasospasm with angina (VSA) causes endothelial dysfunction in the coronary arteries. The aim of this study was to evaluate the thickness of EAT in the anterior interventricular groove (EAT-AIG) using echocardiography in patients who had no obstructive coronary artery disease and were suspected of having VSA...

BACKGROUND: Although a recent randomized trial found no difference between intensive and standard blood pressure (BP) control in patients with diabetes mellitus (DM), the debate over the optimal BP target continues. Thus, the present study investigated the effect of BP on the subclinical left ventricular (LV) function and structural changes in diabetic patients. METHOD: A total of 2649 patients with DM who received echocardiography were enrolled in this study. Study population was stratified by three groups according to BP and presence of hypertension (normal, <130/80mmHg; prehypertension, ≥130/80mmHg without hypertension; hypertension, ≥140/90mmHg or history of hypertension)...

Hyperglycemia is an independent risk factor for diabetic cardiomyopathy in humans; however, the underlying mechanisms have not been thoroughly elucidated. Zebrafish (Danio rerio) was used in this study as a novel vertebrate model to explore the signaling pathways of human adult cardiomyopathy. Hyperglycemia was induced by alternately immersing adult zebrafish in a glucose solution or water. The hyperglycemic fish gradually exhibited some hallmarks of cardiomyopathy such as myocardial hypertrophy and apoptosis, myofibril loss, fetal gene reactivation, and severe arrhythmia...

BACKGROUND: Although calcific aortic valve disease (CAVD) is associated with coronary atherosclerosis, it is not known whether early CAVD is associated with coronary microcirculatory dysfunction (CMD). We sought to investigate the relationship between myocardial blood flow reserve (MBFR) - a measure of CMD, and early CAVD in the absence of obstructive epicardial coronary artery disease. We also determined whether this relationship was independent of coronary artery disease (CAD) and hs-CRP, a marker of systemic inflammation...

BACKGROUND: Metabolic syndrome (MetS) is an endocrinological disease with both metabolic and physiological components. Previous studies have shown a relationship between MetS and left ventricular (LV) dysfunction. A fragmented QRS (fQRS) is a reliable electrocardiogram (ECG) finding with the importance of an indicator of myocardial fibrosis and scarring. In this study, we examined the utility of speckle tracking echocardiography (STE) in assessing LV function in MetS patients with fQRS...
