The inflammatory responses of vascular endothelial cells (VECs) are critical in the development of many cardio-cerebrovascular diseases. Let-7e is an important regulator of endothelial function and inflammation. However, the effects and mechanisms of let-7e on VECs inflammation have not been studied until recently. Thus, we investigated these issues and found that in addition to proliferation, apoptosis and cell adhesion, let-7e was also implicated in the regulation of inflammatory responses through a complex network, including IκBβ and lncRNA lnc-MKI67IP-3...

As a particular severe phenotype of coronary artery disease (CAD), left main coronary artery disease (LMCAD) is heritable. Genetic variants related to prostaglandin metabolism are associated with LMCAD. Cyclooxygenase-2 (COX-2), a key synthase in prostaglandin pathways, displays high density in atherosclerotic lesions and promotes early atherosclerosis in CAD progression. We hypothesized that genetic variants in COX-2 gene contribute to LMCAD phenotype susceptibility compared to more peripheral coronary artery disease (MPCAD)...

A higher incidence of cardiovascular disease (CVD) has been observed in several chronic inflammatory diseases. However, data on sarcoidosis are limited.In this study, 345 patients with incident sarcoidosis in Olmsted County (Minnesota, USA) during 1976-2013 were identified based on comprehensive medical record review. 345 sex- and age-matched comparators were also identified from the same underlying population. Medical records were individually reviewed for CVD, including coronary artery disease, congestive heart failure, atrial fibrillation, cerebrovascular accident, transient ischaemic attack, peripheral arterial disease and abdominal aortic aneurysm...

BACKGROUND: Fibromuscular dysplasia (FMD) is an idiopathic, non-inflammatory, non-atherosclerotic vascular disease, resulting in focal narrowing of small and medium-sized arteries. Systematic recording of clinical data in central databases as in the US and France provided new insights into FMD. The main objectives of this multicentre study were to explore the epidemiology, pattern of vascular involvement, clinical manifestations, and management of FMD patients in Flanders. PATIENTS AND METHODS: Multicentre, retrospective registry of patients diagnosed with FMD based on medical imaging...

Occlusion of the basilar artery can be treated with endovascular thrombectomy, although the results have not been well studied. Persistent fetal cerebrovascular anatomy can lead to unusual presentation of carotid atherosclerotic disease and can be a barrier to successful mechanical thrombectomy if not recognized. This case presents a rare persistent carotico-basilar anastomosis which resulted in basilar occlusion via the persistent hypoglossal artery and coincident absence of contralateral vertebral arterial access due to a left vertebral artery terminating in the left posterior inferior cerebellar artery...

BACKGROUND: Evidence suggests that lacunar infarcts have different etiologies, possibly related to their anatomical location and vascular territory. We investigated the risk factor profiles of patients with new lacunar infarcts in the basal ganglia and deep white matter. METHODS: Within the Second Manifestations of ARTerial disease-Magnetic Resonance study, a prospective cohort on brain changes on MRI in patients with symptomatic atherosclerotic disease, 679 patients (57 ± 9 years) had vascular screening and MRI at baseline and after a mean follow-up of 3...

BACKGROUND: It is unknown how the contemporary burden of atherosclerotic cardiovascular disease (ASCVD) compares with historical trends. METHODS: As part of the Cardiovascular Health in Ambulatory Care Research Team "big data" initiative, we used information from multiple population-based databases to study 20-year temporal trends in hospitalizations and deaths from ASCVD. We calculated hospitalization rates for 6 ASCVD events (acute myocardial infarction, unstable angina, stroke, transient ischemic attack, peripheral arterial disease, and congestive heart failure) and death rates resulting from ischemic heart disease, cerebrovascular disease and circulatory and noncirculatory causes in adults aged 20-105 years in Ontario, Canada from 1994-2014 (to 2012 for deaths)...

Cerebrovascular disease (CVA) is one of the most prevalent causes of death and disability in the United States, and its primary prevention is crucial. For the primary prevention of CVA, it is commonly recommended that all adults should initially undergo an office-based traditional risk assessment using established predictive models, such as the Framingham Stroke Profile Score or the atherosclerotic cardiovascular disease (ASCVD) risk calculator from the American College of Cardiology/American Heart Association (ACC/AHA)...

Cells of the innate and adaptive immune system are key factors in the progression of atherosclerotic plaque, leading to plaque instability and rupture, potentially resulting in acute atherothrombotic events such as coronary artery disease, cerebrovascular disease and peripheral arterial disease. Here, we describe the cloning, expression, purification, and immunoreactivity assessment of a recombinant single-chain variable fragment (scFv) derived from a human anti-αIIbβ3 antibody (HuAb) selected to target atheromatous lesions for the presence of platelets...

Symptomatic carotid artery atherosclerotic disease is an indication for carotid artery endarterectomy. The coexistence of carotid body tumors (CBTs) with symptomatic carotid disease is rarely encountered and adds significant challenges to vascular surgeons, with a reported overall mortality for patients who undergo endarterectomy and tumor excision of 8.8%, as opposed to the 2% for those who had CBT excision only. We describe the case of a 79-year-old female who experienced an acute cerebrovascular accident in the left hemisphere; duplex ultrasound revealed high-grade carotid stenosis in the left side and the presence of a Shamblin I CBT...

BACKGROUND: Meta-analyses of cardiac rehabilitation trials up to 2010 showed a significant reduction in all-cause mortality but many of these trials were conducted before the modern management of acute coronary syndromes. METHODS: We undertook a meta-analysis of contemporary randomised controlled trials published in the period 2010 to 2015, including patients with other forms of atherosclerotic cardiovascular disease, to investigate the impact of cardiovascular prevention and rehabilitation on hard outcomes including survival...

Background Intracranial atherosclerotic stenosis is an important etiology subtype of ischemic stroke. Stenosis severity was thought to be the main reference index for clinical treatment and research. However, stenosis could not reflect the ischemia risk completely, instead the hemodynamic state across the lesion, the extent of collateral circulation, and perfusion impairment downstream the stenosis are more important. Aims We write this review aimed to summarize novel angiographic methods applied in the evaluation of functional severity of ICAS, and commented on their limitations and prospects in future research...

Stroke is the third most common cause of death worldwide following myocardial infaction and malignancies, furthermore, its functional outcome is the worst of all conditions. Cholesterol, especially LDL-cholesterol plays a key role in the formation of atherosclerotic plaques. It has been verified recently that escalating incidence and mortality of cerebrovascular diseases are proportional to increased levels of LDL-cholesterol. Statin therapy undeniably reduces the risk of stroke, however other methods for decreasing lipid levels have not been proved significantly effective...

Atherosclerosis remains the leading cause of long-term mortality and morbidity worldwide, despite remarkable advancement in its management. Vulnerable atherosclerotic plaques are principally responsible for thromboembolic events in various arterial territories such as carotid, coronary, and lower limb vessels. Carotid plaque ulceration is one of the key features associated with plaque vulnerability and is considered a notable indicator of previous plaque rupture and possible future cerebrovascular events. Multiple imaging modalities have been used to assess the degree of carotid plaque ulceration for diagnostic and research purposes...

OBJECTIVES: The acetazolamide challenge test in conjunction with (123)I-IMP single-photon emission computed tomography (SPECT) is a known method of assessing cerebrovascular reserve capacity. In this study, we investigated whether CT perfusion in combination with resting state (123)I-IMP SPECT could be used instead of the acetazolamide challenge test to evaluate hemodynamic compromise in patients with atherosclerotic occlusive disease. METHODS: Twenty consecutive patients with unilateral internal carotid artery or middle cerebral artery steno-occlusive disease were enrolled...
