Abstract:

Abstract BACKGROUND: Cerebral infarction is a major contributor to poor outcome after subarachnoid hemorrhage (SAH). Although usually considered a complication of delayed cerebral ischemia, infarcts may also occur early, in relation to initial brain injury or aneurysm-securing procedures. OBJECTIVE: We analyzed the relative frequency and volume of early vs delayed infarcts after SAH and their relationship to hospital outcome. METHODS: Retrospective review of consecutive patients admitted with aneurysmal SAH over 4 years who had follow-up brain imaging 7 days or later after admission. Imaging 2

Abstract:

This prospective and consecutive study of 74 patients with completed stroke elucidates occurrence, localization and evolution of lacunar infarcts on repeated CT examinations. Twenty patients had large infarcts (diameter >3 cm), 25 medium-sized infarcts (diameter ≥1.5 cm – ≤ 3 cm), and 16 had lacunar infarcts (diameter <1.5 cm). In 13 patients no infarct was seen. The lacunar infarcts were characterized by delayed appearance on CT, low incidence of fog effect, and infrequent presence of contrast enhancement. In 9 of the 16 patients (56%) the lacunar infarct could be identified on the firs

Abstract Introduction: The purpose of this study was to assess the performance of a set of parameters in characterizing simulated infarcts in left ventricular (LV) models with variations in size and transmural extent.

These simulations provided meshes that were used to generate synthetic ultrasonic data within the FIELD II package. The strain components (longitudinal and circumferential) were then estimated over small subsegments of the of segments 7 and 12 (accord

Abstract:

Ventricular dilatation may have important prognostic implications for the survival of patients with left ventricular (LV) dysfunction. To determine the manner and extent to which the left ventricle of the rat remodels and dilates after myocardial infarction, we obtained the passive pressure-volume relationships, chamber stiffness constants, and mass during both the early and late phases. In moderate and large infarcts as inflammation and edema developed, LV weight increased then progressively decreased as a thin scar formed, returning to normal values as a result of compensatory hypertrophy of

The mechanical properties of the healing scar are an important determinant of heart function following myocardial infarction.

Supratentorial infarcts are the most common form of ACM, occuring as a consequence of blood vessel occlusion, which irrigation zone is above tentorium, and it appears in 80% of infarcts.

Background and Purpose: The prognosis of medium vessel occlusions (MeVOs), that is, M2/3 middle cerebral artery, A2/3 anterior cerebral artery, and P2/3 posterior cerebral artery occlusions, is generally better compared with large vessel occlusions, since brain ischemia is less extensive. However, in some MeVO patients, infarcts are seen outside the territory of the occluded vessel (MeVO with discrepant infarcts).

Identification of early ischemic changes (EIC) on noncontrast head CT scans performed within the first few hours of stroke onset may have important implications for subsequent treatment, though early stroke is poorly delimited on these studies.

OBJECTIVE: To investigate the correlation between facial sensory abnormalities and lesional topography in eight patients with lateral medullary infarcts (LMIs). METHOD: We reviewed eight sequential cases of LMIs admitted to the Neurology Division of Hospital das Clínicas/ São Paulo University between July, 2001 and August, 2002 except for one patient who had admitted in 1996 and was still followed in 2002. All patients were submitted to conventional brain MRI including axial T1-, T2-weighted and Fluid attenuated inversion-recovery (FLAIR) sequences. MRIs were evaluated blindly to clinical feat

Abstract:

Mouse myocardial infarction (MI) models are frequently used research tools. The most commonly applied model is coronary artery ligation. However, coronary ligation often gives rise to apical aneurysmatic infarcts of variable size. Other infarct models include cryoinfarction, which produces reproducible infarcts of the anterior wall. Thus far, this model has not been extensively described in mice. Therefore, we developed a murine cryoinfarction model and compared it with coronary ligation. Studies were performed under isoflurane anesthesia with a follow-up of 4 and 8 wk. Cryoinfarction was indu

Background: Calcium overload is a major cause of reperfusion myocardial injury. Multidetector computed tomography (MDCT) has been previously used in visualizing coronary artery calcium, but not calcium deposits in reperfused infarction. Purpose: To assess the ability of MDCT to 1) noninvasively visualize and characterize calcium deposits in reperfused infarcts, and 2) monitor regional wall swelling, regional systolic wall thickening, and infarct resorption.

Coronary occlusion (CO) of 1 h or longer causes transmural myocardial infarction (MI) in the rabbit. We studied how reperfusion of an infarct affected myocardial blood flow (MBF) acutely and after 3 wk of healing. CO was performed in rabbits for 60 or 180 min (n = 22) followed by reperfusion, and MBF to normal and infarcted zones was determined by radioactive microspheres. In a separate series (n = 23), MBF was measured at 21-25 days post-CO in three groups that had either permanent CO or reperfusion after 60 or 180 min of CO. MBF to the infarct was approximately 8 +/- 3% (+/-SE) of normal MBF

Abstract:

Acute myocardial infarction (AMI) can progress to heart failure, which has a poor prognosis. Normally, 60% of stroke volume (SV) is attributed to the longitudinal ventricular shortening and lengthening evident in the atrioventricular plane displacement (AVPD) during the cardiac cycle, but there is no information on how the relationship changes between SV and AVPD before and after AMI. Therefore, the aim of this study was to determine how SV depends on AVPD before and after AMI in two swine models.

We have previously shown that the mRNA for EGF and its receptor (EGFR) are increased in the cerebral blood vessels from stroke-prone spontaneously hypertensive rats (SHRSP) compared to Wistar Kyoto (WKY) rats.

Arterial spin labeling (ASL) is a non-contrast, non-invasive method used for the evaluation of cerebral perfusion, which is now increasingly utilized in everyday clinical practice. As a marker of cerebral blood flow at the capillary level, it has particular utility in stroke assessment. One rarer stroke subtype with non-specific symptomatology that can lead to significant morbidity is the posterior circulation (PC) infarct. As with the more common anterior circulation infarcts, ASL has shown benefit in PC infarcts as well, but has not been extensively explored in the literature nor been direct

P134 Background: Recent estimates of stroke incidence in the US range from 715,000–750,000 annually. These estimates, however, do not reflect silent infarcts and hemorrhages. Since population-based studies have found that prevalence of silent stroke is 10–20 times that of symptomatic, estimates of stroke incidence based solely on symptomatic events may substantially underestimate the annual burden of stroke. Silent strokes contribute to vascular dementia, gait impairment, and other major adverse patient outcomes. Methods: Incidence of silent infarcts for different age strata were derived from

About 10% of children with sickle cell anemia (HbSS) will have an overt stroke by 18 years of age and another 22% will have “silent” cerebral infarcts by 14 years of age. There is a second peak in the incidence of overt ischemic stroke in adults with SCD. Both silent and overt stroke can be accompanied by cognitive impairment and thereby increased risk of academic failure.

Total infarct volume was manually segmented in all patients. When MRI follow-up was available, deep grey matter and grey matter infarct volumes were segmented
