TL;DR: Results suggest that estrogen protects against neointimal injury in the balloon-injured rat, at least in part, by facilitating the reendothelialization of the damaged vessel.
Abstract: Background It has been suggested that reendothelialization of damaged blood vessels protects against the vascular injury response. The goal of the present study was to determine whether estrogen restores endothelial cell function in balloon-injured rat carotid arteries. Methods and Results Ten-week-old male and female Sprague-Dawley rats with intact gonads underwent balloon injury to the right common carotid artery. Female rats were randomized to receive either daily subcutaneous injections of 17β-estradiol (17β-E2; 20 μg · kg−1 · d−1) or vehicle over the course of the study. Vessel morphology was assessed 2 weeks after injury. Significant neointima formation was observed in vehicle-treated males. This response was blunted in vehicle-treated and 17β-E2–supplemented females. Intima-to-media ratios were 1.28±0.23 (males), 0.72±0.07 (vehicle-treated females), and 0.49±0.07 (17β-E2–supplemented females). To test whether reductions in neointimal lesion formation were related to the functional reendothelializat...

TL;DR: Primary analysis of clinical trial data suggests visit-to-visit variability (VVV) of blood pressure is strongly associated with the incidence of cardiovascular disease and VVV of SBP measured in a real-world setting is not random.
Abstract: ObjectivesSecondary analysis of clinical trial data suggests visit-to-visit variability (VVV) of blood pressure is strongly associated with the incidence of cardiovascular disease. Measurement of blood pressure in usual practice settings may be subject to substantial error, calling into question the

TL;DR: The conclusion that TGF-beta plays an important role in hypoxia-induced pulmonary vascular adaptation and IAD in the newborn animal model is supported.
Abstract: Hypoxia causes abnormal neonatal pulmonary artery remodeling (PAR) and inhibition of alveolar development (IAD). Transforming growth factor (TGF)-β is an important regulator of lung development and repair from injury. We tested the hypothesis that inhibition of TGF-β signaling attenuates hypoxia-induced PAR and IAD. Mice with an inducible dominant-negative mutation of the TGF-β type II receptor (DNTGFβRII) and nontransgenic wild-type (WT) mice were exposed to hypoxia (12% O2) or air from birth to 14 days of age. Expression of DNTGFβRII was induced by 20 μg/g ZnSO4 given intraperitoneally daily from birth. PAR, IAD, cell proliferation, and expression of extracellular matrix (ECM) proteins were assessed. In WT mice, hypoxia led to thicker, more muscularized resistance pulmonary arteries and impaired alveolarization, accompanied by increases in active TGF-β and phosphorylated Smad2. Hypoxia-induced PAR and IAD were greatly attenuated in DNTGFβRII mice given ZnSO4 compared with WT control mice and DNTGFβRII mice not given ZnSO4. The stimulatory effects of hypoxic exposure on pulmonary arterial cell proliferation and lung ECM proteins were abrogated in DNTGFβRII mice given ZnSO4. These data support the conclusion that TGF-β plays an important role in hypoxia-induced pulmonary vascular adaptation and IAD in the newborn animal model.

TL;DR: Augmenting O-GlcNAc modification of proteins in the vasculature may represent a novel anti-inflammatory and vasoprotective mechanism in balloon-injured rat carotid arteries.
Abstract: Inflammation plays a major role in vascular disease. We have shown that leukocyte infiltration and inflammatory mediator expression contribute to vascular remodeling after endoluminal injury. This ...

TL;DR: This commentary focuses on generalizability of the findings and what is known about serious adverse effects that may be related to the SPRINT intervention.
Abstract: We thank the editors of Hypertension for the invitation to discuss aspects of the recently published Systolic Blood Pressure Intervention Trial (SPRINT; ClinicalTrials.gov identifier NCT01206062) main results.1 This commentary focuses on generalizability of the findings and what is known about serious adverse effects that may be related to the SPRINT intervention. SPRINT compared the effects of antihypertensive treatment with a systolic blood pressure (SBP) target of <120 mm Hg (intensive treatment) versus <140 mm Hg (standard treatment) in 9361 hypertensive adults ≥50 years of age who had an average SBP of 130–180 mm Hg (the acceptable upper limit decreasing as the number of pretrial antihypertensive medications increased) and were at additional risk for cardiovascular disease (CVD).2 SPRINT was designed to recruit study participants with an average CVD risk of ≈2% per year, equivalent to a Framingham 10-year CVD risk score of 20%.
The main finding in SPRINT was that a primary composite outcome of myocardial infarction, non–myocardial infarction acute coronary syndrome, stroke, acute decompensated heart failure, and CVD death was reduced by ≈25% in the intensive treatment group compared with the standard treatment group. Similarly, all-cause mortality was reduced by ≈27% in the intensive treatment group.
During follow-up, the mean SBP was 121.5 mm Hg in the intensive treatment group and 134.6 mm Hg in the standard treatment group.1 Although many classes of medications were available, emphasis was placed on using classes with the best outcomes in large clinical trials: thiazide-type diuretics, calcium channels blockers, and angiotensin-converting enzyme inhibitors or angiotensin receptor blockers. Other agents, including spironolactone, amiloride, β-blockers, vasodilators, or α-receptor blockers, could be added if necessary. The mean numbers of antihypertensive medications were 2.8 and 1.8 in the intensive treatment and standard treatment groups, respectively.
On balance, the intensive intervention was well tolerated. The trial …

TL;DR: There is, I think, something ethereal about i —the square root of minus one, which seems an odd beast at that time—an intruder hovering on the edge of reality.
Abstract: There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.
Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

TL;DR: The most effective therapy prescribed by the most careful clinician will control hypertension only if patients are motivated, and empathy builds trust and is a potent motivator.
Abstract: "The Seventh Report of the Joint National Committee on Prevention, Detection,
Evaluation, and Treatment of High Blood Pressure" provides a new guideline
for hypertension prevention and management. The following are the key messages(1) In persons older than 50 years, systolic blood pressure (BP) of
more than 140 mm Hg is a much more important cardiovascular disease
(CVD) risk factor than diastolic BP; (2) The risk of CVD, beginning at 115/75
mm Hg, doubles with each increment of 20/10 mm Hg; individuals who are normotensive
at 55 years of age have a 90% lifetime risk for developing hypertension; (3)
Individuals with a systolic BP of 120 to 139 mm Hg or a diastolic BP of 80
to 89 mm Hg should be considered as prehypertensive and require health-promoting
lifestyle modifications to prevent CVD; (4) Thiazide-type diuretics should
be used in drug treatment for most patients with uncomplicated hypertension,
either alone or combined with drugs from other classes. Certain high-risk
conditions are compelling indications for the initial use of other antihypertensive
drug classes (angiotensin-converting enzyme inhibitors, angiotensin-receptor
blockers, β-blockers, calcium channel blockers); (5) Most patients with
hypertension will require 2 or more antihypertensive medications to achieve
goal BP (<140/90 mm Hg, or <130/80 mm Hg for patients with diabetes
or chronic kidney disease); (6) If BP is more than 20/10 mm Hg above goal
BP, consideration should be given to initiating therapy with 2 agents, 1 of
which usually should be a thiazide-type diuretic; and (7) The most effective
therapy prescribed by the most careful clinician will control hypertension
only if patients are motivated. Motivation improves when patients have positive
experiences with and trust in the clinician. Empathy builds trust and is a
potent motivator. Finally, in presenting these guidelines, the committee recognizes
that the responsible physician's judgment remains paramount.

TL;DR: In those older than age 50, systolic blood pressure of greater than 140 mm Hg is a more important cardiovascular disease (CVD) risk factor than diastolic BP, and hypertension will be controlled only if patients are motivated to stay on their treatment plan.
Abstract: The National High Blood Pressure Education Program presents the complete Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure. Like its predecessors, the purpose is to provide an evidence-based approach to the prevention and management of hypertension. The key messages of this report are these: in those older than age 50, systolic blood pressure (BP) of greater than 140 mm Hg is a more important cardiovascular disease (CVD) risk factor than diastolic BP; beginning at 115/75 mm Hg, CVD risk doubles for each increment of 20/10 mm Hg; those who are normotensive at 55 years of age will have a 90% lifetime risk of developing hypertension; prehypertensive individuals (systolic BP 120-139 mm Hg or diastolic BP 80-89 mm Hg) require health-promoting lifestyle modifications to prevent the progressive rise in blood pressure and CVD; for uncomplicated hypertension, thiazide diuretic should be used in drug treatment for most, either alone or combined with drugs from other classes; this report delineates specific high-risk conditions that are compelling indications for the use of other antihypertensive drug classes (angiotensin-converting enzyme inhibitors, angiotensin-receptor blockers, beta-blockers, calcium channel blockers); two or more antihypertensive medications will be required to achieve goal BP (<140/90 mm Hg, or <130/80 mm Hg) for patients with diabetes and chronic kidney disease; for patients whose BP is more than 20 mm Hg above the systolic BP goal or more than 10 mm Hg above the diastolic BP goal, initiation of therapy using two agents, one of which usually will be a thiazide diuretic, should be considered; regardless of therapy or care, hypertension will be controlled only if patients are motivated to stay on their treatment plan. Positive experiences, trust in the clinician, and empathy improve patient motivation and satisfaction. This report serves as a guide, and the committee continues to recognize that the responsible physician's judgment remains paramount.
