Relationship between brachial flow-mediated dilation and carotid intima-media thickness in patients with coronary artery disease. Int Angiol. 2020 Feb 13;: Authors: Toyoda S, Tokoi S, Takekawa H, Matsumoto H, Inami S, Sakuma M, Arikawa T, Abe S, Nakajima T, Hirata K, Inoue T Abstract BACKGROUND: Although flow-mediated vasodilation (FMD) of brachial artery and carotid intima-media thickness (IMT) are important surrogate markers in the process of atherosclerosis, information about relationship between both markers is insufficient. In the present study, we assessed extensively the relationship in patients with coronary artery disease (CAD). METHODS: The values of brachial FMD and carotid ultrasonography findings in 159 patients (67±8 yr, 130 males) with angiographically verified CAD were retrospectively analyzed. RESULTS: In all patients, mean carotid IMT tended to be correlated with FMD, although the correlation was not statistically significant (R=-0.149, P=0.061). Maximum IMT was not correlated with the FMD (R=0.053, P=0.508). In addition, carotid artery diameter was significantly correlated with the FMD (R=0.290, P=0.0002). Prevalence of high IMT value (≥1.0 mm) was higher in the abnormal FMD group (4%>; n=67), compared with the normal FMD group (≥7%; n=24) (P
ConclusionOur study estimated the number of stroke patients undergoing CTA for suspected LVO and those eligible for thrombectomy in relation to the population. Numbers were essentially the same throughout the week, and during office and on-call hours. Our data can be used to make adequate staffing plans.
ConclusionThis propensity score analysis demonstrated that the EVT patients with acute ICAD-related MCA M1 occlusion had similar angiographic and clinical outcomes compared to those with M1 embolism on a similar baseline condition.
Purpose: Many patients with ischemic stroke have concomitant coronary artery disease (CAD). However, it remains unclear which stroke patients should undergo evaluation for asymptomatic CAD, and which screening tools are appropriate. We investigated the role of coronary artery calcium (CAC) score as a screening tool for asymptomatic but severe CAD in acute stroke patients. We determined the selection criteria for CAC screening based on risk factors and cerebral atherosclerosis.Materials and Methods: The present study included consecutive patients with acute stroke who had undergone cerebral angiography and multi-detector co...
ConclusionThe whole brain collateral vasculature status is clearly associated with clinical and radiological outcome but in a multivariate model seems not sufficiently predictive for FIV, mRS and NIHSS outcome at discharge in non-preselected patients admitted to the emergency department with ischemic stroke.
CONCLUSIONS: Acute ischemic stroke with large-vessel occlusion due to calcified emboli is a rare entity in patients undergoing thrombectomy, with considerably worse angiographic outcome and a higher mortality compared with patients with noncalcified thrombi. Good functional recovery at 3 months can still be achieved in about a quarter of patients.
CONCLUSION: Higher GI and GL were positively associated with a higher degree of carotid stenosis in these Chinese cerebral infarction patients, especially in younger patients and women. PMID: 32147606 [PubMed - as supplied by publisher]
ConclusionThe PVHS on 3D BB contrast-enhanced MRI is a highly specific tool for evaluating the location and length of a thrombus in AIS patients.
The objective of this study was to develop a score to predict patients with acute ischemic stroke (AIS) who will not benefit from endovascular treatment (EVT) using computed tomographic angiography (CTA) parameters. Methods: The CTA-ABC score was developed from 3 scales previously described in the literature: the Alberta Stroke Program Early CT Score (0-5 points, 3; 6-10 points, 0), the clot burden score (0-3 points, 1; 4-10 points, 0), and the leptomeningeal Collateral score (0-1 points, 2; 2-3 points, 0). We evaluated the predictive value of CTA parameters associated with symptomatic intracranial hemorrhage (sICH) or...
AbstractBackground and purpose Cardiac thrombi are an important cause of embolic stroke. We studied the diagnostic yield and diagnostic accuracy of cardiac CT angiography (CTA) compared to echocardiography for detection of cardiac thrombi in ischemic stroke patients.MethodsWe performed a systematic review and meta-analysis of the literature on cardiac CTA versus echocardiography for detection of cardiac thrombi in ischemic stroke patients. We included studies (N ≥ 20) in which both cardiac CTA (index test) and echocardiography (reference test) were performed and data on cardiac thrombi were reported. Resul...
ConclusionUltrafast ultrasound imaging is an innovative, easily accessible technique that provides imaging modalities on top of the conventional B-mode. Ultrafast ultrasound biomarkers such as plaque stiffness heterogeneity, WSS and intraplaque micro-flows could help to define the vulnerability of the carotid plaque in order to stratify patients that could benefit most from endarterectomy or intensive medical therapy.
