Asymptomatic Carotid Stenosis Is Associated With Circadian and Other Variability in Embolus Detection
Conclusions: Embolism associated with asymptomatic carotid stenosis shows circadian variation with highest rates 4–6 h before midday. This corresponds with peak circadian incidence of stroke and other vascular complications. These and ASED Study results show that monitoring frequency, duration, and time of day are important in ES detection.
Introduction
Transcranial Doppler (TCD) detected microembolism in the ipsilateral middle cerebral artery (MCA) may help stratify the risk of stroke and other arterial disease complications in persons with advanced (≥60%) asymptomatic carotid stenosis. If so, this t...

Stenosis Length and Degree Interact With the Risk of Cerebrovascular Events Related to Internal Carotid Artery Stenosis
Conclusion: We found a statistically insignificant tendency for the ultrasound-measured length of sICAS<70% to be longer than that of sICAS≥70%. Moreover, the ultrasound-measured length of sICAS<90% was significantly longer than that of sICAS 90%. Among patients with sICAS≥70%, the degree and length of stenosis were inversely correlated. Larger studies are needed before a clinical implication can be drawn from these results.
Introduction
Internal carotid artery stenosis (ICAS) causes around one-fifth of ischemic cerebrovascular stroke and has the highest risk of early stroke recurrence...

Fractal dimension based carotid plaque characterization from three-dimensional ultrasound images
AbstractIrregularity of the plaque surface associated with previous plaque rupture plays an important role in the risk estimation of stroke caused by carotid atherosclerotic lesions. Thus, the aim of this study is to develop and validate novel vulnerability biomarkers from three-dimensional ultrasound (3DUS) images by analyzing the surface morphological characteristics of carotid plaque using fractal geometry features. In the experiments, a total of 38 3DUS plaque images were obtained from two groups of patients treated with 80 mg of atorvastatin or placebo daily for 3 months respectively. Two types of 3D fractal dimens...

Atherosclerosis in systemic lupus erythematosus
Publication date: June 2017Source: Best Practice & Research Clinical Rheumatology, Volume 31, Issue 3Author(s): Sara Croca, Anisur RahmanAbstractCardiovascular disease (CVD), comprising coronary heart disease and stroke, is one of the most important causes of death in patients with systemic lupus erythematosus (SLE). The risks of developing both clinical CVD and sub-clinical atherosclerosis are increased in patients with SLE. This increase is not fully explained by traditional cardiovascular risk factors such as smoking, hypertension and elevated cholesterol, and it is believed that immune dysfunction also contributes to C...

Differentiation of Serum sLOX-1 and NO Levels in Acute Ischemic Stroke Patients with Internal Carotid Artery Stenosis and Those Without Internal Carotid Artery Stenosis.
Conclusion: There are higher sLOX-1 and lower NO levels in AIS patients with ICAS when comparing those with NICAS. These parameters may become the novel potential biomarkers for predicting risk to acute ischemic stroke.

Previous use of statins and atrial electrical remodeling in patients with cryptogenic stroke.
CONCLUSIONS: Our results show lower PWD values in cryptogenic stroke patients previously treated with statins. These findings provide support to the hypothesis that statins may play a role in modulating atrial electrophysiological and structural properties, preventing the occurrence of a slowed and heterogeneous atrial conduction and finally, reducing the occurrence of AF.

Ultrasonographical Features Associated with Progression of Atherosclerosis in Patients with Moderate Internal Carotid Artery Stenosis
AbstractCarotid artery stenosis (CAS) is a leading cause of ischemic stroke. Plaque stabilization is a major management approach. Information about the ultrasonographical and clinical features associated with the progression of moderate internal carotid artery (ICA) stenosis (50 –69%) could assist with prognostication and risk factor modifications. We evaluated 287 patients with moderate ICA stenosis (50–69%) and subsequently evaluated them at follow-up points at 12, 24, and 36 months. Patients were divided into three groups according to the degree of ICA stenosis: pro gression (70–99%,n = 48), stable (50–69%,...

Cardiovascular Events After Exposure to Nilotinib in Chronic Myeloid Leukemia: Long-term Follow-up
Conclusion The incidence of CVEs and the frequency of asymptomatic PAD in this population was low, and CVEs were associated with cardiovascular risk factors. Aggressive risk factor modification and applying standard definitions for measuring cardiovascular outcomes might have contributed to the findings. Further prospective and adequately powered studies are needed to explore the effect of the cardiovascular risk profile on CVEs in CML patients taking nilotinib. Micro-Abstract The present study evaluated the incidence of cardiovascular events (CVEs) in 63 chronic myeloid leukemia (CML) patients after long-term exposure to ...

The Association of Arsenic Metabolism with Cancer, Cardiovascular Disease, and Diabetes: A Systematic Review of the Epidemiological Evidence
Conclusions:
Population level of iAs% and DMA%, but not MMA%, were associated with arsenic exposure levels. Overall, study findings suggest that higher MMA% was associated with an increased risk of cancer and cardiovascular disease, while lower MMA% was associated with an increased risk of diabetes and metabolic syndrome. Additional population-based studies and experimental studies are needed to further evaluate and understand the role of arsenic exposure in arsenic metabolism and the role of arsenic metabolism in disease development. https://doi.org/10.1289/EHP577

Resistant Atherosclerosis Clinical Sciences
Background and Purpose—Recent studies indicate that patients with lower levels of low-density lipoprotein cholesterol (LDL-C) have greater regression of coronary plaque. In 2002, we found that carotid plaque progression doubled cardiovascular risk. In 2003, we therefore implemented a new approach, treating arteries instead of risk factors. Since then, we have seen many patients with carotid plaque progression despite very low levels of LDL-C, suggesting other causes of atherosclerosis. We studied the relationship of achieved LDL-C and change in LDL-C to progression/regression of atherosclerosis, before and after 2003.Met...
