Age-related disruption of microvascular endothelium exacerbates hypertension and sarcopenia; and atherosclerosis is a well-known biological response to vascular endothelial injury. Therefore, prevalence of atherosclerosis among hypertensive elderly subjects may partly indicate the presence of an appropriate response to endothelial injury. We conducted a cross-sectional study of 795 elderly hypertensive Japanese subjects aged 60-89 years. Since platelet level is an indicator of vascular repair activity, subjects were stratified by platelet counts...

Importance: Mitochondrial dysfunction is a core component of the aging process and may play a key role in atherosclerotic cardiovascular disease. Mitochondrial DNA copy number (mtDNA-CN), which represents the number of mitochondria per cell and number of mitochondrial genomes per mitochondrion, is an indirect biomarker of mitochondrial function. Objective: To determine whether mtDNA-CN, measured in an easily accessible tissue (buffy coat/circulating leukocytes), can improve risk classification for cardiovascular disease (CVD) and help guide initiation of statin therapy for primary prevention of CVD...

BACKGROUND/AIMS: Previous studies have demonstrated that leonurine, a unique alkaloid compound of Herba leonuri, can exert anti-oxidative and anti-inflammatory effects on the development of atherosclerosis (AS). This study was designed to investigate the effects of leonurine on cholesterol efflux from THP-1 macrophage-derived foam cells and development of atherosclerotic lesions in apoE-/- mice, and further determine the potential mechanisms. METHODS: Human THP-1 cells were fully differentiated into foam cells by the pre-treatment with phorbol-12-myristate-13-acetate (PMA) and oxidized density lipoproteins (ox-LDL)...

BACKGROUND: Although current alcohol consumption is a risk factor for incident atrial fibrillation (AF), the more clinically relevant question may be whether alcohol cessation is associated with a reduced risk. METHODS AND RESULTS: We studied participants enrolled in the Atherosclerosis Risk in Communities Study (ARIC) between 1987 and 1989 without prevalent AF. Past and current alcohol consumption were ascertained at baseline and at 3 subsequent visits. Incident AF was ascertained via study ECGs, hospital discharge ICD-9 codes, and death certificates...

Epidemiological studies strongly support the role of procyanidin-rich beverages and fruit in the prevention of cardiovascular diseases. Procyanidins extracted from the litchi pericarp (LPPC), a new source of procyanidins, were isolated and identified in our laboratory and have been proven to possess strong antioxidant activity in vitro. In the present study, we investigated the anti-atherosclerotic effects of LPPC in apolipoprotein E knockout (ApoE KO) mice fed a high fat diet for 24 weeks. LPPC (100 mg kg(-1) body mass daily) significantly reduced the atherosclerotic lesion size (P < 0...

Age-related macular degeneration (AMD) is the leading cause of irreversible central vision loss in developed countries. With the aging of population, AMD will become globally an increasingly important and prevalent disease worldwide. It is a complex disease whose etiology is associated with both genetic and environmental risk factors. An extensive decline in the quality of life and progressive need of daily living assistance resulting from AMD among those most severely affected highlights the essential role of preventive strategies, particularly advising patients to quit smoking...

PURPOSE OF REVIEW: Many guidelines exist for the use of statins in the primary prevention of atherosclerotic cardiovascular disease (ASCVD). Few have focused on disease specific states that predispose to ASCVD. This review is intended to focus on the recommendations and evidence in inflammatory diseases that predispose to an increased risk of ASCVD beyond what conventional cardiac risk scores would predict. RECENT FINDINGS: Certain autoimmune inflammatory diseases such as rheumatoid arthritis (RA), systemic lupus erythematous (SLE), and psoriasis/psoriatic arthritis have all been shown to increase the risk of ASCVD...

Atherosclerosis is a chronic inflammatory disease caused by dyslipidemia and mediated by both innate and adaptive immune responses. Inflammation is a critical factor at all stages of atherosclerosis progression. Proinflammatory cytokines accelerate atherosclerosis progression, while anti-inflammatory cytokines ameliorate the disease. Accordingly, strategies to inhibit immune activation and impede immune responses towards anti-inflammatory activity are an alternative therapeutic strategy to conventional chemotherapy on cardiocerebrovascular outcomes...

The role of platelets in the development of thrombosis and abrupt closure after angioplasty is well recognized. However, the direct impact of platelets on neointima formation after arterial injury remains undetermined. Here we show that neointima formation after carotid artery wire injury reduces markedly in CD40(-/-)apoE(-/-) mice but only slightly in CD40L(-/-)apoE(-/-) mice, compared with apolipoprotein E-deficient (apoE(-/-)) mice. Wild-type and CD40-deficient platelets were isolated from blood of apoE(-/-) and CD40(-/-)apoE(-/-) mice, respectively...

For patients with symptomatic intracranial atherosclerosis (ICAS), antithrombotic agents are the mainstay of therapy. Anticoagulation (warfarin) is not widely used since it is not more effective than aspirin and carries a high risk of bleeding. New oral anticoagulants are showing promise, but their use has not been investigated in appropriate clinical trials. Since the recurrent stroke risk is high with aspirin monotherapy, dual antiplatelets are considered in the early stage of symptomatic ICAS. Based on the Clopidogrel in High-Risk Patients with Acute Nondisabling Cerebrovascular Events (CHANCE) and Stenting and Aggressive Medical Management for Preventing Recurrent Stroke in Intracranial Stenosis (SAMMPRIS) results, aspirin plus clopidogrel has been recommended...

Atherosclerosis, the progressive buildup of plaque within arterial blood vessels, can lead to fatal downstream events, such as heart attack or stroke. A key event contributing to the development of atherosclerosis is the infiltration of monocytes and its associated inflammation, as well as the formation of lipid-laden macrophage foam cells within the vessel wall. IL-37 is recognized as an important anti-inflammatory cytokine expressed especially by immune cells. This study was undertaken to elucidate the role of macrophage-expressed IL-37 in reducing the production and effects of proinflammatory cytokines, preventing foam cell formation, and reducing the development of atherosclerosis...

A20, a negative regulator of nuclear factor κB signaling, has been shown to attenuate atherosclerotic events. Transforming growth factor beta-activated kinase 1 (TAK1) plays a critical role in TNFα-induced atherosclerosis via endothelial nitric oxide (NO) synthase (eNOS) uncoupling and NO reduction. In the study, we investigated the hypothesis that A20 protected endothelial cell injury induced by TNFα through modulating eNOS activity and TAK1 signalling. Human umbilical vein endothelial cells (HUVECs) were stimulated by TNFα...

Coronary CT angiography (CTA) is a highly accurate test for the diagnosis of coronary artery disease (CAD), with its use guided by numerous contemporary appropriate use criteria and clinical guidelines. Unique among non-invasive tests for CAD, coronary CTA provides direct visualization of coronary atherosclerosis for the assessment of angiographic stenosis, as well as validated measures of plaque vulnerability. Long-term studies now clearly demonstrate that the absence of CAD on coronary CTA identifies a patient that is at very low risk for future cardiovascular events...

Atherosclerosis (AS) is an inflammatory disease linked to endothelial dysfunction. Melatonin is reported to possess substantial anti-inflammatory properties, which has proven to be effective in AS. Emerging literature suggests that pyroptosis plays a critical role during AS progression. However, whether pyroptosis contributes to endothelial dysfunction and the underlying molecular mechanisms remained unexploited. This study was designed to investigate the anti-pyroptotic effects of melatonin in atherosclerotic endothelium and to elucidate the potential mechanisms...

ICAM-1 overexpression and subsequent adhesion of leukocytes to endothelial cells play critical roles in the early stage of atherosclerosis. Danshenol A (DA) is an abietane-type diterpenoid isolated from traditional Chinese herb Salvia miltiorrhiza Bunge. The mechanisms under its regulation of adhesion of molecular expression are explored. Here, the effect of DA on TNF-α-induced ICAM-1 expression was investigated in endothelial cells. TNF-α-induced ICAM-1 expression and subsequent adhesion of monocytes, as well as elevated reactive oxygen species (ROS) generation and NOX4 expression were all significantly reversed by DA, siNOX4 and NOX4 inhibitor GKT137831...

PURPOSE OF REVIEW: Our aim was to examine the current evidence behind prescribing statins to individuals over 65 years of age with emphasis on those older than 75. Individuals over 75 years of age may often have multiple comorbidities and take many medications. Additionally, they are often underrepresented in randomized controlled trials (RCTs) of statins in older populations. While results of RCTs demonstrate the benefit of statin therapy in both primary and secondary prevention patients, clinicians must more carefully consider adverse effects and drug-drug interactions before prescribing statin therapy as well as determining the intensity in older individuals...
