Background Epicardial fat is a true visceral fat deposit with adverse effects through the secretion of numerous proinflammatory and proatherogenic cytokines. Previous studies showed an association between aortic valve sclerosis and coronary artery disease. The aim of this study was to determine the correlation between epicardial fat thickness and aortic valve sclerosis. Method The study involved 225 patients who were admitted for coronary angiography due to new-onset angina. They underwent transthoracic echocardiography and epicardial fat thickness was determined...

BACKGROUND: The relationship between ideal cardiovascular health reflected in the cardiovascular health score (CVHS) and valvular heart disease is not known. The purpose of this study was to determine the association of CVHS attainment through midlife to late life with aortic stenosis prevalence and severity in late life. METHODS AND RESULTS: The following 6 ideal cardiovascular health metrics were assessed in ARIC (Atherosclerosis Risk in Communities) Study participants at 5 examination visits between 1987 and 2013 (visits 1-4 in 1987-1998 and visit 5 in 2011-2013): smoking, body mass index, total cholesterol, blood pressure, physical activity, and blood glucose...

OBJECTIVE: We aimed to investigate whether increased whole blood viscosity (WBV) could be an important factor for the occurrence of aortic valve sclerosis (AVS) Subjects and Methods: A total of 209 patients were enrolled into the study. WBV was calculated using the hematocrit and total plasma protein at a low shear rate (LSR) and high shear rate (HSR). AVS was defined as irregular valve thickening and calcification, without evidence of obstruction of outflow, as documented by a peak transvalvular velocity of < 2...

BACKGROUND: Aortic valve disease increases velocity and changes the way blood enters the aorta. Over time, the biomechanical environment can cause aortic remodelling. We hypothesised that aortic geometry and wall stress would be different in patients with aortic valve disease compared to controls. METHODS: We examined 40 patients with aortic sclerosis (n=10), mild (n=10), moderate (n=10) and severe (n=10) aortic stenosis, and also 10 control cases. The thoracic aorta of each case was reconstructed into a three-dimensional model from computed tomography...

BACKGROUND: Epicardial fat tissue (EAT) is associated with coronary as well as aortic valve calcification. The study aim was to determine whether EAT thickness is different in patients with and without aortic valve stenosis (AVS). METHODS: A cohort of 200 consecutive patients with severe AVS and 200 matched patients without AVS were included retrospectively in the study. EAT thickness was quantified, using transthoracic echocardiography, as the space between the epicardial wall of the myocardium and the visceral layer of the pericardium...

Incidental cardiovascular findings are common and can be found in up to 70% of patients. Previously, several reports about incidental findings (IFs) on whole body computed tomography (CT) were published. However, no previous study investigated cardiovascular IFs in patients with unclear finding situation and trauma of unknown origin on whole body CT.The radiological database of 2 university hospitals was screened for patients with trauma of unknown origin and unclear finding situation investigated by whole body CT...

The prevalence and prognostic implications of ventricular conduction disturbances in aortic stenosis (AS) have not been extensively evaluated. The present retrospective study investigated the prevalence and prognostic implications of ventricular conduction abnormalities (including the QRS morphology and duration) in AS. A total of 1,245 patients (mean age 66 ± 14 years, 62.8% men) with varying AS severity (aortic sclerosis 33.9%, mild AS 11.5%, moderate AS 29.9%, and severe AS 24.7%) were evaluated. Demographic, clinical variables, and presence of ventricular conduction abnormalities on the electrocardiogram (based on QRS morphology and duration) were related to occurrence of all-cause mortality, correcting for occurrence of aortic valve replacement...

Aortic valve diseases are the most common among the valvular heart diseases. Significant increases in the frequency of degenerative aortic sclerosis and aortic stenosis (AS) are observed, particularly with aging of the population and diminished rheumatic heart disease. Aortic regurgitation (AR) is less common in the elderly and is accompanied by AS rather than pure AR. Considering the comorbid diseases, fragility and cognitive functions in elderly patients, special approach is needed during diagnosis, evaluation, treatment and follow-up...

Systemic sclerosis is a connective tissue disorder that frequently involves the heart. All cardiac structures can be involved but aortic valve involvement is rare. We report a case of an 83-year-old man with a history of systemic sclerosis presenting with shortness of breath. A transthoracic echocardiogram revealed severe aortic stenosis that could not be explained by other causes. These patients often pose challenges in management as they are not surgical candidates. Transaortic valvular implantation is a viable option for these patients...

BACKGROUND: Overproduction of extracellular matrix (ECM) protein by aortic valve interstitial cells (AVICs) plays an important role in valvular sclerosis (thickening) associated with the early pathobiology of aortic stenosis. Accumulation of oxidized low-density lipoprotein (oxLDL) is observed in sclerotic aortic valve and may have a mechanistic role in valvular disease progression. Lysophosphatidylcholine (LysoPC) is a component of oxLDL and has multiple biological activities. This study was to test the hypothesis that oxLDL and LysoPC upregulate ECM protein production in human AVICs...

Background: Blood viscosity and aortic sclerosis (AS) are strong predictors of cardiovascular events. The effects of blood viscosity on AS have not been studied adequately. We aimed to investigate the potential connection between whole blood viscosity (WBV) and AS. Methods: AS was detected by transthoracic echocardiography. The estimation of WBV was carried out at both high shear rate (HSR) (208/s) and low shear rate (LSR) (0.5/s) by previously validated formulae using hematocrit (HcT) and total protein (TP) in g/L...

BACKGROUND/AIM: Aortic valve sclerosis (AVS) is characterized by lipid deposition and calcific infiltration on the edge of aortic leaflets without significant restriction of motion. The SYNTAX Score (SS) is an important method for evaluating coronary artery disease (CAD). Many studies showed that there is an important relation between the SS and undesired cardiac outcomes. In our study, we investigated the correlation between the SS and AVS by including both ACS and stable CAD cases. MATERIALS AND METHODS: We enrolled 543 patients with CAD who underwent coronary angiography into this cross-sectional study between September 2013 and September 2014...

INTRODUCTION: Diabetes mellitus is a well-defined risk factor for peripheral artery disease (PAD), but protects against the development and growth of abdominal aortic aneurysm (AAA). Diabetes mellitus is associated with arterial stiffening and peripheral arterial media sclerosis. Advanced glycation end-products (AGEs) are increased in diabetes mellitus and cardiovascular disease. AGEs are known to form cross-links between proteins and are associated with arterial stiffness. Whether AGEs contribute to the protective effects of diabetes mellitus in AAA is unknown...

Calcific aortic valve disease (CAVD) is a leading cardiovascular disorder in the elderly. Diseased aortic valves are characterized by sclerosis (fibrosis) and nodular calcification. Sclerosis, an early pathological change, is caused by aortic valve interstitial cell (AVIC) proliferation and overproduction of extracellular matrix (ECM) proteins. However, the mechanism of aortic valve sclerosis remains unclear. Recently, we observed that diseased human aortic valves overexpress growth factor neurotrophin 3 (NT3)...

Gastric antral vascular ectasia (GAVE) continues to be a challenge in both diagnosis and treatment. GAVE has a diverse group of associations and presumed causes, including cirrhosis, chronic renal failure and autoimmune connective tissue diseases. However, in most occasions, the management plan of GAVE itself is the same whatever the underlying disease by using Argon plasma coagulation (APC). Herein, we will discuss three cases of systemic sclerosis-associated GAVE presenting with either acute or chronic gastrointestinal bleeding showing variable responses to APC...

CONTEXT: Making a diagnosis can be difficult for learners as they must integrate multiple clinical variables. Diagnostic schemes can help learners with this complex task. A diagnostic scheme is an algorithm that organises possible diagnoses by assigning signs or symptoms (e.g. systolic murmur) to groups of similar diagnoses (e.g. aortic stenosis and aortic sclerosis) and provides distinguishing features to help discriminate between similar diagnoses (e.g. carotid pulse). The current literature does not identify whether scheme layouts should guide learners to reason one step at a time in a terminally branching scheme or weigh multiple variables simultaneously in a hybrid scheme...
