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 over-production of extracellular matrix (ECM) proteins. However, the mechanism of aortic valve sclerosis remains unclear. Recently, we observed that diseased human aortic valves over-express 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...

INTRODUCTION: Aortic valve sclerosis has been shown to be associated with increased incidence, chances of developing myocardial infarction and even death. The epidemiological risk factors causing calcification of aortic valves have also been found to cause atherosclerosis. AIM: To analyse the epidemiological risk factors causing aortic valve sclerosis which have been studied in details and analysed to see whether they cause any significant increase in the incidence of cardiovascular events...

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...

BACKGROUND: Atherosclerosis is regarded as a combination of two major separate diseases: atherosis and sclerosis. Sclerotic component depends on deterioration of elastic properties of the aortic wall and is called aortic stiffness. The most valuable, non-invasive method of aortic stiffness assessment is echocardiography, which allows to calculate the aortic stiffness index (ASI). ASI is an independent predictor of all-cause and cardiovascular mortality in different groups of patients...

Quadricuspid aortic valve (QAV) is a rare congenital cardiac defect. Aortic regurgitation is the predominant hemodynamically relevant abnormality in patients with QAV, and the main reason for patients requiring valve surgery. Calcific valve disease of the left heart valves is classified as 'low embolic risk' according to current guidelines. However, it remains an important risk factor of cardiovascular events, including ischemic stroke. A 71-year-old woman presented with new-onset aphasia and hemiparesis of the right side of her body...

Systemic hypertension and aortic valve stenosis (AVS) are both age-related diseases. Severe aortic stenosis affects ≈2% to 5% of adults age > 65 years. Systemic hypertension (HTN) is a frequent comorbidity in patients with AVS and is coexistent for a longer period of time before AVS is treated. Essential systemic hypertension, per se, plays an important role in the creation of lesions on the aortic side of the valve, the region of higher exposure to tension stress. The subsequent endothelial defect represents the principal site of inflammatory process and oxidative stress, leading to aortic sclerosis and calcification...

BACKGROUND: With age, aortic valve cusps undergo varying degrees of sclerosis which, sometimes, can progress to calcific aortic valve stenosis (AVS). To perform a retrospective clinico-pathologic investigation in patients with calcific AVS. METHODS: We characterized and graded the structural remodeling in 236 aortic valves (200 tricuspid and 36 bicuspid) from patients with calcific AVS (148 males; average 72years); possible relationships between general/clinical/echocardiographic characteristics and the histopathologic changes were explored...

Although microvascular disease is a hallmark of systemic sclerosis (SSc), a higher prevalence of macrovascular disease and a poorer related prognosis have been reported in SSc than in the general population. The simultaneous assessment of prognostically relevant functional properties of larger and smaller arteries, and their effects on central hemodynamics, has never been performed in SSc using the state-of-the-art techniques. Thirty-four women with SSc (aged 61±15 years, disease duration 17±12 years, and blood pressure 123/70±18/11 mm Hg) and 34 healthy women individually matched by age and mean arterial pressure underwent the determination of carotid-femoral (aortic) and carotid-radial (upper limb) pulse wave velocity (a direct measure of arterial stiffness), aortic augmentation (a measure of the contribution of reflected wave to central pulse pressure), and aortobrachial pulse pressure amplification (brachial/aortic pulse pressure) through applanation tonometry (SphygmoCor)...

BACKGROUND: Acute administration of the oral 5-HT1A receptor agonist buspirone, which is commonly used as an anxiolytic drug, may improve compromised lower esophageal sphincter function. In an open-label trial we assessed the effects of buspirone on esophageal motor function and symptoms in patients with esophageal involvement associated with systemic sclerosis (SSc). METHODS: Thirty consecutive patients with SSc and symptomatic esophageal involvement, despite treatment with proton pump inhibitors, underwent high resolution manometry and chest computed tomography for assessment of motor function and esophageal dilatation, respectively...

Calcific aortic valve disease (CAVD) represents a spectrum of disease spanning from milder degrees of calcification of valve leaflets, i.e., aortic sclerosis, to severe calcification i.e., aortic stenosis (AS) with hemodynamic instability. The prevalence of CAVD is increasing rapidly due to the aging of the population, being up to 2.8% among patients over 75 years of age. Even without significant aortic valve stenosis, aortic sclerosis is associated with a 50% increased risk of myocardial infarction and death from cardiovascular causes...

OBJECTIVE: Growing evidence suggested an association between aortic valve sclerosis (AVSc) and cardiovascular (CV) events. However, little is known about the association of AVSc with major markers of subclinical atherosclerosis. We performed a meta-analysis of literature studies to address this issue. METHODS: Studies on the relationship between AVSc and common carotid artery intima-media thickness (IMT), prevalence of carotid plaques (CPs), flow-mediated dilation (FMD), aortic pulse wave velocity (PWV) and augmentation index (AIx) were systematically searched in electronic databases...

BACKGROUND: Activin receptor-like kinase 4 (ALK4), a downstream receptor of transforming growth factor-β superfamily, is highly expressed in the mammal heart. Upregulated ALK4 expression and activated ALK4-small mother against decapentaplegic (Smad)2/3 signaling have been reported to play a pivotal role in tumorigenesis and in the development of systemic sclerosis. However, the role of ALK4-Smad2/3 pathway in the pathogenesis of cardiac hypertrophy and cardiac fibrosis remains unknown...
