Abstract P448: Interaction Between Ischemic Brain Inȷury and Amyloid-{beta} Deposition in Cognitive Decline; Possible Cognitive Protection by AT2Receptor Activation Session Title: Hypertension and Aging and Cerebrovascular Disease and Stroke
Conclusion: Ischemic brain injury could enhance Aβ-induced cognitive impairment with possible involvement of enhanced oxidative stress, neuron degeneration, and breakdown of RAGE-mediated Aβ clearance. AT2 receptor activation in VSMC could play inhibitory roles in the cognitive decline induced by ischemic brain damage and Aβ deposition.

Abstract P482: Different Hemodynamic Phenotypes Of Isolated Systolic Hypertension In Adolescents Session Title: Antihypertensive Drugs and Pharmacology, Patient-Provider-Healthcare System Issues, and Pediatric and Adolescent Hypertension
Objective: Isolated systolic hypertension (ISH) is a dominant form of primary hypertension (PH) in adolescents. Some of them present with normal central systolic blood pressure (cSBP), a phenomenon called spurious hypertension (sHT). The study was aimed to describe hemodynamics of PH in relation to cSBP, central pulse pressure (cPP) and target organ damage (TOD) in adolescents referred because of PH.Patients and Methods: In 267 children (59 girls; 14.9 ±2.6 years) referred with arterial hypertension, in whom secondary hypertension was excluded, 24 hour ABPM, left ventricular mass index (LVMi), carotid intima-media thickne...

Endothelial Mineralocorticoid Receptor Mediates Parenchymal Arteriole and Posterior Cerebral Artery Remodeling During Angiotensin II-Induced HypertensionNovelty and Significance Brain
The brain is highly susceptible to injury caused by hypertension because the increased blood pressure causes artery remodeling that can limit cerebral perfusion. Mineralocorticoid receptor (MR) antagonism prevents hypertensive cerebral artery remodeling, but the vascular cell types involved have not been defined. In the periphery, the endothelial MR mediates hypertension-induced vascular injury, but cerebral and peripheral arteries are anatomically distinct; thus, these findings cannot be extrapolated to the brain. The parenchymal arterioles determine cerebrovascular resistance. Determining the effects of hypertension and ...

Aldosterone Target NGAL (Neutrophil Gelatinase-Associated Lipocalin) Is Involved in Cardiac Remodeling After Myocardial Infarction Through NF{kappa}B PathwayNovelty and Significance Heart
In conclusion, NGAL, a downstream MR activation target, is a key mediator of post-MI cardiac damage. NGAL may be a potential therapeutic target in cardiovascular pathological situations in which MR is involved.

Uric Acid Is a Strong Risk Marker for Developing Hypertension From PrehypertensionNovelty and Significance Hyperuricemia and Prehypertension
Prehypertension frequently progresses to hypertension, a condition associated with high morbidity and mortality from cardiovascular diseases and stroke. However, the risk factors for developing hypertension from prehypertension remain poorly understood. We conducted a retrospective cohort study using the data from 3584 prehypertensive Japanese adults (52.1±11.0 years, 2081 men) found to be prehypertensive in 2004 and reexamined in 2009. We calculated the cumulative incidences of hypertension over 5 years, examined risk factors, and calculated odds ratios (ORs) for developing hypertension after adjustments for age, sex, bo...

Cerebrovascular Reactivity and Vascular Activation in Postmenopausal Women With Histories of PreeclampsiaNovelty and Significance Preeclampsia
This study examined an association between pregnancy history and CVR using a subgroup of 40 age- and parity-matched pairs of women having histories of preeclampsia (n=27) or normotensive pregnancy (n=29) and the association of activated blood elements with CVR. Middle cerebral artery velocity was measured by Doppler ultrasound before and during hypercapnia to assess CVR. Thirty-eight parameters of blood cellular elements, microvesicles, and cell–cell interactions measured in venous blood were assessed for association with CVR using principal component analysis. Middle cerebral artery velocity was lower in the preeclampsi...

Day-by-Day Variability of Home Blood Pressure and Incident Cardiovascular Disease in Clinical PracticeNovelty and Significance Blood Pressure Variability
We assessed the relationship between day-by-day home blood pressure (BP) variability and incident cardiovascular disease (CVD) in clinical practice. J-HOP study (Japan Morning Surge-Home Blood Pressure) participants underwent home BP monitoring in the morning and evening for a 14-day period, and their BP levels and BP variability independent of the mean (VIM) were assessed. Incident CVD events included coronary heart disease and stroke. Cox models were fitted to assess the home BP variability–CVD risk association. Among 4231 participants (mean±SD age, 64.9±10.9 years; 53.3% women; 79.1% taking antihypertensive medicati...

Effect of Lowering Diastolic Pressure in Patients With and Without Cardiovascular DiseaseNovelty and Significance SPRINT Trial
Systolic and diastolic blood pressure thresholds, below which cardiovascular events increase, are widely debated. Using data from the SPRINT (Systolic Blood Pressure Intervention Trial), we evaluated the relation between systolic and diastolic pressure and cardiovascular events among 1519 participants with or 7574 without prior cardiovascular disease. Using Cox regression, we examined the composite risk of myocardial infarction, other acute coronary syndrome, stroke, heart failure, or cardiovascular death, and follow-up systolic and diastolic pressure were analyzed as time-dependent covariates for a median of 3.1 years. Mo...

Changes in Cerebral Arteries and Parenchymal Arterioles With AgingNovelty and Significance Cerebrovascular Dysfunction With Aging
Vascular aging fundamentally contributes to large and small vessel disease. Despite the importance of such changes for brain function, mechanisms that mediate such changes are poorly defined. We explored mechanisms that underlie changes with age, testing the hypothesis that ROCK (Rho kinase) plays an important role. In C57BL/6 mice, baseline diameters of isolated pressurized parenchymal arterioles were similar in adult (4–5 month) and old mice (22±1 month; ≈15±1 µm). Endothelium-dependent dilation was impaired in old mice compared with adults in a pathway-specific manner. Vasodilation to NS-309 (which activates smal...
