Silent brain infarcts, peripheral vascular disease and the risk of cardiovascular events in patients with hypertension.

Background And Aims: We aimed to study the relationship between cerebral small vessel disease (cSVD) lesions, as markers of subclinical target organ damage (TOD) in the brain, and incident cardiovascular events (CVE).

Methods: Data from the ISSYS (Investigating Silent Strokes in hYpertensives Study), which is a longitudinal and observational study conducted in patients with hypertension aged 50-70 years, and stroke-free at the inclusion. At the baseline visit, participants underwent a clinical interview, a brain MRI, urine and blood sampling collection and vascular testing studies.

GRECOS Project (Genotyping Recurrence Risk of Stroke): The Use of Genetics to Predict the Vascular Recurrence After Stroke.

Background And Purpose: Vascular recurrence occurs in 11% of patients during the first year after ischemic stroke (IS) or transient ischemic attack. Clinical scores do not predict the whole vascular recurrence risk; therefore, we aimed to find genetic variants associated with recurrence that might improve the clinical predictive models in IS.

Methods: We analyzed 256 polymorphisms from 115 candidate genes in 3 patient cohorts comprising 4482 IS or transient ischemic attack patients.

Dementia Rating Scale-2 normative data for middle-and older-aged Castilian speaking Spaniards.

Objectives: The Dementia Rating Scale-2 (DRS-2) is frequently used as a dementia screening tool in clinical and research settings in Spain. The present study describes DRS-2 Total and subscale scores in community-dwelling Spaniards, aged 50-71, and provides normative data for its use in Castilian Spanish-speaking individuals.

Methods: The sample consisted of 798 individuals who participated in an observational study on essential hypertension.

Assessment of enlarged perivascular spaces and their relation to target organ damage and mild cognitive impairment in patients with hypertension.

Background And Purpose: Enlarged perivascular spaces (EPVS) have been recently considered a feature of cerebral small vessel disease. They have been related to aging, hypertension and dementia but their relationship with hypertension related variables (i.e.

High daytime and nighttime ambulatory pulse pressure predict poor cognitive function and mild cognitive impairment in hypertensive individuals.

High blood pressure accelerates normal aging stiffness process. Arterial stiffness (AS) has been previously associated with impaired cognitive function and dementia. Our aims are to study how cognitive function and status (mild cognitive impairment, MCI and normal cognitive aging, NCA) relate to AS in a community-based population of hypertensive participants assessed with office and 24-hour ambulatory blood pressure measurements.

Blood and CSF biomarkers in brain subcortical ischemic vascular disease: Involved pathways and clinical applicability.

Vascular dementia is the second most common type of dementia after Alzheimer’s disease (AD). Subcortical ischemic vascular disease refers to a form of vascular cognitive impairment characterized by the presence of diffuse white matter hyperintensities (WMHs) and multiple lacunar infarcts. These neuroimaging findings are mainly caused by cerebral small-vessel disease (cSVD) and relate to aging and cognitive impairment, but they can also be silent and highly prevalent in otherwise healthy individuals.

Prevalence and associated factors of silent brain infarcts in a Mediterranean cohort of hypertensives.

Silent brain infarcts (SBIs) are detected by neuroimaging in approximately 20% of elderly patients in population-based studies. Limited evidence is available for hypertensives at low cardiovascular risk countries. Investigating Silent Strokes in Hypertensives: a Magnetic Resonance Imaging Study (ISSYS) is aimed to assess the prevalence and risk factors of SBIs in a hypertensive Mediterranean population.

Investigating silent strokes in hypertensives: a magnetic resonance imaging study (ISSYS): rationale and protocol design.

Background: Silent brain infarcts are detected by neuroimaging in up to 20% of asymptomatic patients based on population studies. They are five times more frequent than stroke in general population, and increase significantly both with advancing age and hypertension. Moreover, they are independently associated with the risk of future stroke and cognitive decline.

Cognitive assessment protocol design in the ISSYS (Investigating Silent Strokes in hYpertensives: a magnetic resonance imaging Study).

Hypertension and silent cerebrovascular lesions (SCL) detected by brain magnetic resonance imaging (MRI) are associated with an increased risk of cognitive decline. In a prospective observational study in 1000 hypertensive patients, aged 50-70 years, with no prior history of stroke or dementia, we will study the presence of mild cognitive impairment (MCI) and the relationship between SCL and cognition. All participants will be assessed by means of the Dementia Rating Scale-2 (DRS-2) and will undergo a brain MRI.

Update on the Serum Biomarkers and Genetic Factors Associated with Safety and Efficacy of rt-PA Treatment in Acute Stroke Patients.

An accurate understanding of the mechanisms underlying an individual's response to rt-PA treatment is critical to improve stroke patients' management. We thus reviewed the literature in order to identify biochemical and genetic factors that have been associated with safety and efficacy of rt-PA administration after stroke.
