OBJECTIVE: Inadequate sleep is associated with increased risk of cardiovascular events; however, the associations between sleep duration or quality and cardiac function or structure are not well understood. This cross-sectional study was conducted to investigate to what extent sleep duration and quality are associated with left ventricular (LV) diastolic dysfunction or structural deterioration. METHODS: A total of 31,598 healthy Korean adults who received echocardiography and completed the Pittsburg Sleep Quality Index were enrolled in this study...

It is well documented that chronic kidney disease patients have an extremely high risk of developing cardiovascular (CV) disease (CVD) compared to the general population. Declining renal function itself represents a continuum of CV risk, and in those individuals who survive to reach end-stage renal disease, the risk of suffering a cardiac event is uncomfortably and unacceptably high. Several pathophysiological pathways have been suggested to account for this, including endothelial dysfunction, dyslipidemia, inflammation, left ventricular hypertrophy, troponins, phosphate, vitamin D, fibroblast growth factor-23, and NT-proBNP...

Left ventricular hypertrophy (LVH) ultimately leads to heart failure in conditions of increased cardiac pre- or afterload. The bone-derived phosphaturic and sodium-conserving hormone fibroblast growth factor-23 (FGF23) and its co-receptor Klotho have been implicated in the development of uremic LVH. Using transverse aortic constriction (TAC) in gene-targeted mouse models, we examine the role of Fgf23 and Klotho in cardiac hypertrophy and dysfunction induced by pressure overload. TAC profoundly increases serum intact Fgf23 due to increased cardiac and bony Fgf23 transcription and downregulation of Fgf23 cleavage...

AIMS: HIIT (high-intensity interval training) has the potential to reduce cardiometabolic risk factors, but the effects on cardiac remodeling and local RAS (renin-angiotensin system) in mice fed high-fat or high-fructose diets still need to be fully addressed. MAIN METHODS: Sixty male C57BL/6 mice (12weeks old) were randomly divided into three groups, control (C), High-fat (HF), or High-fructose diet (HRU) and were monitored for eight weeks before being submitted to the HIIT...

BACKGROUND/PURPOSE: Left ventricular hypertrophy is a major cause of heart failure in aging population. This study is to determine whether an excess dietary fat is lipotoxic or lipoprotein to the hypertrophic aging heart. METHODS: At 44-week-old, a normal chow (12% fat) was replaced a high-fat diet (HFD; 45% fat) for randomly selective spontaneously hypertensive rats (SHR + HFD, n = 6) and Wistar-Kyoto rats (WKY + HFD, n = 6, normotensive control). Others (SHR, n = 11; WKY, n = 10) were continuously fed with normal diets...

BACKGROUND Primary aldosteronism can be caused by adrenocortical adenoma and is usually associated with left ventricular hypertrophy. Biventricular cardiac hypertrophy and heart failure in the presence of a pre-existing atrial septal defect (ASD) are a rare association of primary aldosteronism. CASE REPORT A 33-year-old woman with resistant hypertension and refractory hypokalemia presented with signs and symptoms of heart failure. She had previously been diagnosed having a right adrenal tumor and ostium secundum type ASD...

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...

Hypertension-induced left ventricular hypertrophy (LVH) is an independent risk factor for heart failure. Regression of LVH has emerged as a major goal in the treatment of hypertensive patients. Here, we tested our hypothesis that the valosin-containing protein (VCP), an ATPase associate protein, is a novel repressor of cardiomyocyte hypertrophy under the pressure overload stress. Left ventricular hypertrophy (LVH) was determined by echocardiography in 4-month male spontaneously hypertensive rats (SHRs) vs. age-matched normotensive Wistar Kyoto (WKY) rats...

BACKGROUND AND PURPOSE: Xanthine oxidoreductase (XOR), which catalyzes purine catabolism, has two interconvertible forms, xanthine dehydrogenase and xanthine oxidase, the latter of which produces superoxide during uric acid (UA) synthesis. An association between plasma XOR activity and cardiovascular and renal outcomes has been previously suggested. We investigated the potential association between cardiac parameters and plasma XOR activity among cardiology patients. METHODS AND RESULTS: Plasma XOR activity was measured by [13C2,15N2]xanthine coupled with liquid chromatography/triplequadrupole mass spectrometry...

BACKGROUND: In cardiomyocytes from patients with hypertrophic cardiomyopathy, mechanical dysfunction and arrhythmogenicity are caused by mutation-driven changes in myofilament function combined with excitation-contraction (E-C) coupling abnormalities related to adverse remodeling. Whether myofilament or E-C coupling alterations are more relevant in disease development is unknown. Here, we aim to investigate whether the relative roles of myofilament dysfunction and E-C coupling remodeling in determining the hypertrophic cardiomyopathy phenotype are mutation specific...

Detecting coronary artery disease at a subclinical level has always been a challenging task for cardiologists. Various non-invasive echocardiographic approaches such as measurements of left ventricular hypertrophy, diastolic function, left atrial enlargement, valve sclerosis and calcification, epicardial fat thickness, and pulse wave velocity have been proposed to integrate the available risk-charts. The present review is a collection of evidence that supports the role of the above mentioned features in cardiac risk stratification, summarizing the state of the art in non-invasive echocardiographic coronary risk assessment...

Fabry's disease (FD) is a severe congenital metabolic disorder characterized by the deficient activity of lysosomal exoglycohydrolase alpha-galactosidase, characterized by glycosphingolipid deposition in several cells, such as capillary endothelial cells, renal, cardiac, and nerve cells. As a systemic disease leading to a contemporaneous myocardial and renal dysfunction, FD might be an example of cardiorenal syndrome type 5 (CRS-5). Kidney damage is commonly characterized by proteinuria, isosthenuria and altered tubular function when occurs at the second-third decade, azotemia and end-stage renal disease in third-fifth decade...

Aortic stenosis is common and an important cause of morbidity and mortality. Prevalence will increase significantly in forthcoming decades as a function of the ageing population; treatment by means of surgery or percutaneous intervention is expensive. Epidemiological, mechanistic and interventional studies are therefore vital to determine optimal and innovative treatments and their funding. Recent studies suggest that aortic stenosis is not a passive degenerative disease, but an active process involving several pathways, including lipid infiltration, chronic inflammation, fibrosis formation, osteoblast activation, and active valve mineralisation...

BACKGROUND: Because of global aging, the prevalence of heart failure with preserved ejection fraction (HFpEF) continues to rise. Although HFpEF pathophysiology remains incompletely understood, endothelial inflammation is stated to play a central role. Cellular senescence is a process of cellular growth arrest linked with aging and inflammation. We used mice with accelerated aging to investigate the role of cellular senescence in HFpEF development. METHODS AND RESULTS: Senescence-accelerated mice (SAM, n=18) and control mice with normal senescence (n=15) were fed normal chow or a high-fat, high-salt diet (WD)...
