Neuroimaging and Blood Biomarkers in Functional Prognosis after Stroke.
CONCLUSION: Although some biomarkers and neuroimaging techniques have potential predictive value, none of the studies were able to support its use, alone or in association, as a clinically useful functionality predictor model. All the evaluated markers were considered insufficient to predict functional prognosis at three months, when applied in the first hours after stroke. Additional studies are necessary to identify reliable predictive markers for functional prognosis after ischemic stroke. PMID: 28229841 [PubMed - in process]

Subclinical Vascular Composites Predict Clinical Cardiovascular Disease, Stroke, and Dementia: The Multi-Ethnic Study of Atherosclerosis (MESA)
CONCLUSIONS: Subclinical vascular composites of arteriosclerosis and atherosclerosis may be useful biomarkers to inform the vascular pathways contributing to events of CVD, CHD, stroke, and dementia.PMID:37205504 | PMC:PMC10187443 | DOI:10.1101/2023.05.01.23289364

Increased Risk for Intracranial Arterial Stenosis in Subjects With Coronary Artery Calcification Clinical Sciences
Conclusions— The risk for ICAS was significantly increased in middle-aged Korean subjects with CAC compared with that in those without CAC. These findings suggest the possibility of a separate undetected atherosclerotic focus in subjects with 1 atherosclerotic event.

Relative Contributions of Sympathetic, Cholinergic, and Myogenic Mechanisms to Cerebral Autoregulation Clinical Sciences
Conclusions— Our results suggest that myogenic effects occur outside the active region of autoregulation, whereas neurogenic influences are largely responsible for cerebral blood flow control within it. However, our model of cerebral autoregulation left 38% of the cerebral pressure–flow relationship unexplained, suggesting that there are other physiological mechanisms that contribute to cerebral autoregulation.

Fibroblast Growth Factor-23 and Cardiovascular Disease in the General Population: The Multi-Ethnic Study of Atherosclerosis Original Articles
Conclusions— Higher serum FGF-23 concentrations are associated with subclinical cardiac disease and with new heart failure and coronary disease events, but not with carotid intima-media thickness or stroke. FGF-23 may be a novel cardiovascular risk factor in the general population.

Comparison of Coronary Artery Calcium Presence, Carotid Plaque Presence, and Carotid Intima-Media Thickness for Cardiovascular Disease Prediction in the Multi-Ethnic Study of Atherosclerosis Epidemiology
Conclusions— In adults without CVD, CAC presence improves prediction of CVD and CHD more than carotid plaque presence or high IMT. CAC and carotid ultrasound parameters performed similarly for stroke/transient ischemic attack event prediction.

Can HRT in early menopause cut heart disease risk?
ConclusionThis double-blind RCT found that women taking HRT less than six years after the menopause had slower artery wall thickening than those taking a placebo. This represented the main measure of atherosclerosis progression tested; other measures showed no difference, so the results were not as conclusive as they could have been. Women taking HRT 10 or more years after menopause also showed no difference in atherosclerosis progression compared with a placebo, further complicating the picture.An important limitation of this study is the lack of a patient relevant endpoint, such as cardiovascular events or mortality. Pre...

3D Ultrasonic Tissue Characterization for Asymptomatic Carotid Atherosclerosis
Carotid plaque histology has confirmed that intraplaque hemorrhage and enlarging lipid-cores are important determinants of plaque rupture and stroke. Noninvasive characterization of these features may identify individuals at risk for stroke. Two-dimensional (2D) longitudinal-sectional ultrasound images have been used to predict plaque histology, but a single slice provides limited information. Tissue-characterization from 3D ultrasound imaging may offer more comprehensive information. We developed a clinical 3D ultrasound protocol to quantify plaque composition (hemorrhage, lipid, calcium and fibromuscular tissue), measure...

Normocalcaemic, vitamin D sufficient hyperparathyroidism ‐ high prevalence and low morbidity in the general population A long‐term follow‐up study, the WHO MONICA project, Gothenburg, Sweden
ConclusionsThis small random population study showed that nHPT was common, 11% at follow‐up. Only one individual developed mild hypercalcaemia in 13 years. Previous S‐PTH was predictive of nHPT and hypertension was prevalent, but no increase in hard end points was seen over a 17‐year period.This article is protected by copyright. All rights reserved.

Comparison of Carotid Plaque Score and Coronary Artery Calcium Score for Predicting Cardiovascular Disease Events: The Multi-Ethnic Study of Atherosclerosis Epidemiology
BackgroundCoronary artery calcium (CAC) predicts coronary heart disease (CHD) events better than carotid wall plaque presence; however, differences in the utility of CAC burden and carotid plaque burden across the spectrum of cardiovascular disease (CVD) events is unknown.Methods and ResultsCVD, CHD and stroke/transient ischemic attack (TIA) events were evaluated prospectively in a multiethnic cohort without CVD at baseline. Carotid plaque score was determined by the number of ultrasound‐detected plaques in the common, bifurcation, and internal carotid artery segments. CAC was detected by computed tomography. Predictive ...

Association between physical activity and sedentary behaviour on carotid atherosclerotic plaques: an epidemiological and histological study in 90 asymptomatic patients.
CONCLUSION: In this cross-sectional study of asymptomatic patients who underwent endarterectomy (i) higher reported PA, (ii) intensity of PA and (iii) lower reported SB were associated with lower prevalence of intraplaque haemorrhage. This could be a mechanism whereby PA protects against cerebrovascular disease (stroke) and death. PMID: 30842104 [PubMed - as supplied by publisher]

Shape-Based Approach for Coronary Calcium Lesion Volume Measurement on Intravascular Ultrasound Imaging and Its Association With Carotid Intima-Media Thickness
Conclusions— Since carotid IMT is an independent prognostic factor for myocardial infarction, and calcium lesions are correlated with stroke risk, we believe that this automated system for calcium volume measurement could be useful for assessing patients’ cardiovascular risk.
