Zinc Protects Against
Diabetes-Induced Changes in the Aorta - Medscape, 6/4/13 -
"These results suggest that
zinc supplementation provides a significant protection against
diabetes-induced pathogenic changes in the aorta without gender difference in
the type 1 diabetic mouse model. The aortic protection by zinc against
diabetes-induced pathogenic changes is associated with the up-regulation of both
MT and Nrf2 expression" - See

How did stevia get
mainstream? - BBC News, 6/3/13 - "A
naturally-sourced sugar substitute called stevia
apparently has no calories, no carbohydrates, and does not raise blood sugar
levels ... The concentrated extracts are about 300 times as sweet as sugar ...
We don't know how the body responds to being primed for an influx of sugar that
it never receives ... It may be that it fools your brain into thinking that it
needs to release more insulin ... Using my own undistinguished palette, I was
unable to taste the difference in a stevia-sweetened bar of chocolate. But an
informal office taste test suggested that there is still a notable difference to
some, which may be enough to put off consumers" - See
stevia
products at iHerb.
Throat Cancer Link to Oral Sex Gains Credence - NYTimes.com, 6/3/13 -
"In the 1980s, only a small number of
throat cancers were linked to HPV
infection ... Now, about 70 percent of all throat cancers are caused by HPV, up
from roughly 15 percent three decades ago ... Men are three times more likely to
be diagnosed than women with HPV-related throat cancer ... The cancers typically
occur decades after initial infection with HPV ... partners of people with
throat cancers caused by HPV were not at greater risk of developing oral HPV
infections themselves"
Companies pay almost $6,000 extra per year for each employee who smokes -
Science Daily, 6/3/13 - "smoking
accounts for nearly one in every five deaths -- or about 443,000 -- in the
United States each year ... excess absenteeism costs an average of $517 per
year; "presenteeism," or reduced productivity related to the effects of nicotine
addiction, $462; smoke breaks, $3,077; and extra health care costs (for
self-insured employers), $2,056 ... For employers who provide defined benefit
plans, meaning they pay retirees a set amount in pension each year, a smoker's
early death could result in an annual cost reduction of an estimated $296"
Daily sunscreen can slow skin aging, study finds - NBCNews.com, 6/3/13 -
"The researchers randomly assigned 903 adults, ages
25-55, to use a broad spectrum sunscreen every day with frequent reapplications
or to use sunscreen at their discretion ... The adults using daily sunscreen
were 24 percent less likely to show increased aging" - [Video]
Vegetarian diets associated with lower risk of death - Science Daily, 6/3/13
- "The adjusted hazard ratio (HR) for all-cause
mortality in all vegetarians combined vs.
nonvegetarians was 0.88, or 12 percent lower, according to the study results.
The association also appears to be better for men with significant reduction in
cardiovascular disease mortality and IHD death in vegetarians vs.
nonvegetarians. In women, there were no significant reductions in these
categories of mortality, the results indicate"
Impact of Oral Nutritional Supplementation on Hospital Outcomes - The
American Journal of Managed Care, 2/13/13 - "Using the
instrumental variables method, this study found that the use of ONS led to
statistically significant decreases in inpatient LOS, episode cost, and
readmission. Given the high prevalence of malnutrition among inpatient
populations, these results suggest that ONS use could help improve outcomes at
relatively low cost to the healthcare system. Today, hospitals are facing
pressures to find low-cost, highly effective therapy while maintaining quality
of care. By increasing ONS use, hospitals can improve hospitalization outcomes
and decrease healthcare spending"
Probiotics Prevent Diarrhea Related to Antibiotic Use, Review Shows -
Science Daily, 5/30/13 - "Antibiotics
disturb the beneficial bacteria that live in the gut and allow other harmful
bacteria like C. difficile to take hold. Although some people infected with C.
difficile show no symptoms, others suffer diarrhea
or colitis. The so-called "good bacteria" or yeast in
probiotic foods and supplements may offer a safe, low-cost way to help
prevent C. difficile-associated diarrhea (CDAD). This finding is important
because CDAD is expensive to treat ... Probiotics taken in conjunction with
antibiotics reduced the number of people who suffered diarrhea by 64%" -

Self-Administered Injection
Boosts Low Sex Drive in Women - Medscape, 5/30/13 -
"Subcutaneous injections of the melanocortin receptor agonist bremelanotide
effectively and safely treat premenopausal women suffering from
female sexual dysfunction ... Nausea was
the most common side effect, but this occurred early after the injection, was
mild, and stopped with continued use. Other side effects were flushing and
headache"
Omega-3
fatty acids may help heal a broken heart - Science Daily, 5/30/13 -
"The potency of these compounds corresponds to
concentrations that have been measured in the blood of human subjects taking
high dose fish oil supplements for short
periods of time. In rabbits, researchers treated the artery with RvD at the time
of the balloon angioplasty procedure by
infusing the drug directly into the vessel, and found that this one-time
treatment reduced inflammation and subsequent scarring of the vessel after one
month"
Artificial sweeteners may do more than sweeten: It can affect how the body
reacts to glucose - Science Daily, 5/29/13 - "Our
results indicate that this artificial sweetener is not inert -- it does have an
effect ... we need to do more studies to determine whether this observation
means long-term use could be harmful ... gave subjects either water or
sucralose to drink before they consumed
a glucose challenge test ... When study participants drank sucralose, their
blood sugar peaked at a higher level than when they drank only water before
consuming glucose ... Insulin levels also rose about 20 percent higher ... when
people routinely secrete more insulin, they can become resistant to its effects,
a path that leads to type 2 diabetes"
Is It Better to Walk or Run? - NYTimes.com, 5/29/13 -
"The walkers turned out to be hungry, consuming about 50
calories more than they had burned during their hourlong treadmill stroll ...
The runners, on the other hand, picked at their food, taking in almost 200
calories less than they had burned while running ... The runners also proved
after exercise to have significantly higher
blood levels of a hormone called peptide YY, which has been shown to suppress
appetite ... runners had far less risk of high blood pressure, unhealthy
cholesterol profiles, diabetes and heart disease than their sedentary peers. But
the walkers were doing even better. Runners, for instance, reduced their risk of
heart disease by about 4.5 percent if they ran an hour a day. Walkers who
expended the same amount of energy per day reduced their risk of heart disease
by more than 9 percent"
Changing
Gut Bacteria Through Diet Affects Brain Function - Science Daily, 5/28/13 -
"Time and time again, we hear from patients that they
never felt depressed or anxious until they started experiencing problems with
their gut ... Researchers divided the women into three groups: one group ate a
specific yogurt containing a mix of several
probiotics -- bacteria thought to have a positive
effect on the intestines -- twice a day for four weeks; another group consumed a
dairy product that looked and tasted like the yogurt but contained no
probiotics; and a third group ate no product at all ... compared with the women
who didn't consume the probiotic yogurt, those who did showed a decrease in
activity in both the insula -- which processes and integrates internal body
sensations, like those form the gut -- and the somatosensory cortex during the
emotional reactivity task ... Further, in response to the task, these women had
a decrease in the engagement of a widespread network in the brain that includes
emotion-, cognition- and sensory-related areas. The women in the other two
groups showed a stable or increased activity in this network" - See

Surgery Trumps Proton Pump
Inhibitors for Acid Reflux - Medscape, 5/28/13 -
"transoral incisionless fundoplication was superior to maximal-dose PPIs in
eliminating daily troublesome typical and atypical symptoms in selected patients
... The procedure reconstructs the gastroesophageal valve restoring its
competency and re-establishing the barrier to reflux ... We are talking about
the total elimination of symptoms at 6 months, not a 50% reduction ... Patients
in surgery group underwent fundoplication with the EsophyX2 device ... Nearly
three quarters of the surgery group reported being satisfied with their current
health condition at 6 months, compared with only 5% of the PPI group"

New
evidence that egg white protein may help high blood pressure - Science
Daily, 4/9/13 - "We have evidence from the laboratory
that a substance in egg white –– it’s a peptide, one of the building blocks of
proteins –– reduces blood pressure about as much as a low dose of Captopril, a
high-blood-pressure drug ... Yu and colleagues, who are with Clemson University,
used a peptide called RVPSL ... They set out to further document RVPSL’s
effects, using laboratory rats that develop high blood pressure and are
stand-ins for humans in such early research on hypertension ... RVPSL did not
have apparent toxic effects and lowered blood pressure by amounts comparable to
low doses of Captopril"

"The study evaluates the effects of genistein on blood
pressure (BP) and ultrastructural changes in kidney of fructose-fed hypertensive
rats ... Genistein administration lowered BP, restored ACE, PKC-βII and eNOS
expression and preserved renal ultrastructural integrity. These findings
demonstrate that genistein has effects on eNOS activity in renal cells, leading
to eNOS activation and NO synthesis. These effects could have been mediated by
activation of PKC-βII. The observed benefits of genistein make it a promising
candidate for therapy of diabetic kidney disease" - See

Dark
chocolate, cocoa compounds, may reduce blood pressure - Science Daily,
8/14/12 - "The researchers reviewed evidence from
short-term trials in which participants were given dark chocolate or cocoa
powder daily and found that their blood pressure dropped slightly compared to a
control group ... Cocoa contains compounds called flavanols, thought to be
responsible for the formation of nitric oxide in the body. Nitric oxide causes
blood vessel walls to relax and open wider, thereby reducing blood pressure. The
link between cocoa and blood pressure stems from the discovery that the
indigenous people of San Blas Island in Central American, who drink
flavanol-rich cocoa drinks every day, have normal blood pressure regardless of
age ... Flavanol-rich chocolate or cocoa powder reduced blood pressure on
average by 2-3 mm Hg" - [Abstract]
- Note: I'm betting that this formula will cover most of those flavanols:

Big
doses of vitamin C may lower blood pressure - Science Daily, 4/18/12 -
"Miller and his colleagues reviewed and analyzed data
from 29 randomized, controlled, previously published clinical trials that
reported systolic and/or diastolic blood pressure values and also compared
vitamin C intake to a placebo. What they found is that taking an average of 500
milligrams of vitamin C daily -- about five times the recommended daily
requirement -- reduced blood pressure by 3.84 millimeters of mercury in the
short term. Among those diagnosed with hypertension, the drop was nearly 5
millimeters of mercury ... By comparison, Miller says, patients who take blood
pressure medication such as ACE inhibitors or diuretics (so-called "water
pills") can expect a roughly 10 millimeter of mercury reduction in blood
pressure" - Note: I don't consider 500 mg "Big doses". See vitamin C at Amazon.com.

similar. The vegetarians (mainly the vegans) were also less likely to be using
antihypertensive medications. Defining hypertension as systolic BP > 139 mmHg or
diastolic BP > 89 mmHg or use of antihypertensive medications, the odds ratio of
hypertension compared with omnivores was 0.37 (95 % CI 0.19, 0.74), 0.57 (95 %
CI 0.36, 0.92) and 0.92 (95 % CI 0.50, 1.70), respectively, for vegans,
lacto-ovo vegetarians and partial vegetarians. Effects were reduced after
adjustment for BMI ... CONCLUSIONS: We conclude from this relatively large study
that vegetarians, especially vegans, with otherwise diverse characteristics but
stable diets, do have lower systolic and diastolic BP and less hypertension than
omnivores. This is only partly due to their lower body mass"

Curcumin and Piperine
Prevent Remodeling of Aorta - Medscape, 12/26/11 -
"N-nitro-L-arginine-methylester (L-NAME) is a nonspecific inhibitor of all three
NO synthase (NOS) isoforms (neuronal - nNOS; inducible - iNOS; endothelial -
eNOS) and causes an increase of blood pressure in a dose-dependent manner when
administered to the experimental animals ... Administration of piperine or
curcumin to animals with L-NAME-induced hypertension lead to a decrease of blood
pressure, curcumin causing a more significant drop. Similar hypertension
reducing effect of curcumin has been reported recently by Nakmreong et al.[34]
Another study[25] registered a significant decrease of blood pressure after
intravenous piperine administration. Piperine treatment was effective also in
lowering blood pressure in rats with L-NAME-induced experimental hypertension
described by Kumar et al.[36] The combination of curcumin and piperine in our
experiment did not cause a statistically significant blood pressure decrease
(with the exception of the third week) but it is apparent that it copies the
course of the piperine graph curve. These differences in the results are
probably related to different mechanisms of effect by the spices on blood
pressure" - See

Hypothalamic
gene expression in ω-3 PUFA-deficient male rats before, and following,
development of hypertension - Hypertens Res. 2011 Nov 10 -
"Dietary deficiency of ω-3 fatty acids (ω-3 DEF)
produces hypertension in later life ... Animals were fed experimental diets that
were deficient in ω-3 fatty acids, sufficient in short-chain ω-3 fatty acids or
sufficient in short- and long-chain ω-3 fatty acids, from the prenatal period
until 10 or 36 weeks-of-age. There was no difference in blood pressure between
groups at 10 weeks-of-age; however, at 36 weeks-of-age ω-3 DEF animals were
hypertensive in relation to sufficient groups. At 10 weeks, expression of
angiotensin-II(1A) receptors and dopamine D(3) receptors were significantly
increased in the hypothalamic tissue of ω-3 DEF animals. In contrast, at 36
weeks, α(2a) and β(1) adrenergic receptor expression was significantly reduced
in the ω-3 DEF group. Brain docosahexaenoic acid was significantly lower in ω-3
DEF group compared with sufficient groups. This study demonstrates that dietary
ω-3 DEF causes changes both in the expression of key genes involved in central
blood pressure regulation and in blood pressure. The data may indicate that
hypertension resulting from ω-3 DEF is mediated by the central adrenergic
system" - See

Isomer-specific effects of conjugated linoleic acid on blood pressure, adipocyte
size and function - Br J Nutr. 2011 Sep 23:1-9 -
"Consumption of conjugated linoleic acid (CLA) has been shown to modulate
cytokine release from adipocytes and positively influence blood pressure in
younger rats, but its physiological actions in older models with established
hypertension and isomer-specific effects on adipocyte size remain to be
determined. Therefore, we investigated the effects of CLA isomers on adipocyte
size in relation to blood pressure and adipokine production by hypertrophic
adipocytes in older fa/fa Zucker rats with established hypertension. fa/fa
Zucker rats were fed with cis(c)9, trans(t)11-CLA or t10, c12-CLA isomers for 8
weeks and compared with lean and obese rats fed with the control diet. Blood
pressure and adipocyte size were subsequently measured. Collagenase-isolated
adipocytes were size-separated and angiotensinogen and adiponectin protein
levels quantified by Western blotting. The t10, c12-CLA group had reduced blood
pressure, fewer large adipocytes and increased serum adiponectin.
Angiotensinogen was present at higher levels in the large adipocytes, whereas
the converse was observed for adiponectin. The beneficial effects of the t10,
c12-CLA isomer on blood pressure and adipocyte size in vivo may be due to its
ability to reduce the number of large adipocytes, which alters the levels of
vasoactive molecules secreted from adipose tissue" - See

were markedly greater in hypertensive subjects. Significant and greater BP
reductions were also observed in trials using carbohydrate, but not milk
products, as the control diet. Meta-regression analyses further revealed a
significantly inverse association between pre-treatment BP and the level of BP

Noninvasive SBP differed significantly (P < 0.001) from week 3, both noninvasive
and invasive ABP increased significantly (P < 0.001), and exercise capacity
significantly decreased (P < 0.001) in the fructose group compared with the
control group. The individual effects of swimming and taurine supplementation
were incapable of preventing the development of hypertension and SBP
significantly (P < 0.001) increased in the FE and FT groups; exercise capacity
in those groups remained similar to control. The combined effects of exercise
and taurine alleviated hypertension and significantly increased exercise
capacity in the FET group. Insulin resistance increased significantly and plasma
nitric oxide (NO) decreased significantly in the F, FE, and FT groups. Both
parameters remained similar to control values in the FET group with an

potassium ≥ 3.5 mmol L(-1) were defined as normokalemia (group 3) ... Group 2
patients had significant higher systolic and diastolic blood pressure (DBP),
log-transformed plasma aldosterone concentration, log-transformed
aldosterone-to-renin ratio and lower serum potassium level than groups 1 and 3.
In echocardiographic measurement, group 2 patients had higher LV mass index
(LVMI) than groups 1 and 3. In multivariate analysis for factors affecting LVMI
in PA patients, only serum potassium level (P = 0.001), use of spironolactone (P
= 0.004) and DBP (P = 0.005) were independent factors. In the TDI study, both
groups 2 and 3 had lower e' and E/e' values than group 1. Conclusions Serum
potassium level is significantly associated with LVMI in PA patients. Compared
with essential hypertensive patients, PA patients had a greater impairment of
cardiac diastolic function" - See

Role of
vitamin D in arterial hypertension - Expert Rev Cardiovasc Ther. 2010
Nov;8(11):1599-608 - "Vitamin D deficiency is highly
prevalent and may contribute to arterial hypertension. The antihypertensive
effects of vitamin D include suppression of renin and parathyroid hormone levels
and renoprotective, anti-inflammatory and vasculoprotective properties. Low
25-hydroxyvitamin D levels, which are used to classify the vitamin D status, are
an independent risk factor for incident arterial hypertension. Meta-analyses of
randomized controlled trials showed that vitamin D supplementation reduces
systolic blood pressure by 2-6 mmHg ... vitamin D might be useful for the
treatment of arterial hypertension as well as other chronic diseases. Therefore,
we recommend that testing for and treating vitamin D deficiency in patients with

Dark
chocolate lowers blood pressure, research finds - Science Daily, 6/28/10

to the real-life effects of eating chocolate. We've found that consumption
can significantly, albeit modestly, reduce blood pressure for people with
high blood pressure but not for people with normal blood pressure ... The
pressure reduction seen in the combined results for people with
hypertension, 5mm Hg systolic, may be clinically relevant -- it is
comparable to the known effects of 30 daily minutes of physical activity
(4-9mm Hg) and could theoretically reduce the risk of a cardiovascular event

However, those who had high uric acid levels and ate the most salt were 32
percent more likely to develop high blood pressure while those with high urine

Relation
Between Blood Pressure and Vascular Events and Mortality in Patients With
Manifest Vascular Disease: J-Curve Revisited - Hypertension. 2011 Nov 7 -
"Recent studies have challenged the notion that "lower
is better" for blood pressure in relation to vascular events and mortality in
patients with vascular disease, whereas practice guidelines currently recommend
to lower blood pressure to <130/80 mm Hg ... For this purpose, 5788 patients
with symptomatic vascular disease enrolled in the Secondary Manifestations of
Arterial Disease Study were followed-up for the occurrence of new vascular
events (ie, myocardial infarction, stroke, or vascular death) and all-cause
mortality. During a median of 5.0 years (interquartile range: 2.6-8.1 years),
788 patients experienced a new vascular event, and 779 died. Overall, the
covariate-adjusted relationship between mean baseline systolic, diastolic, or
pulse pressure and the occurrence of vascular events followed a J-curve with
increased event rates above and below the nadir blood pressure of 143/82 mm Hg.
A similar nonlinear relationship was found for diastolic pressure and all-cause
mortality. Elevated blood pressure was not associated with increased morbidity
and mortality in patients with recently diagnosed coronary artery disease, ≥65
years, and having >60 mm Hg pulse pressure. Importantly, especially in these
subgroups, low blood pressure could also be a symptom rather than a cause of
disease. Blood pressure level below and above 143/82 mm Hg is, thus, an
independent risk factor for recurrent events in patients with manifest vascular
disease"

Influence of
low high-density lipoprotein cholesterol on arterial stiffening and left
ventricular diastolic dysfunction in essential hypertension - J Clin
Hypertens (Greenwich). 2011 Oct;13(10):710-5 - "In
univariate regression analysis, HDL cholesterol was inversely associated with
arterial stiffness parameter and E/Em (r=-0.23 and r=-0.27, respectively,
P<.01). The association of HDL cholesterol with arterial stiffness and LV
diastolic function was observed in both men and women. Triglycerides were weakly
correlated with arterial stiffness parameter and E/Em, while low-density
lipoprotein and total cholesterol were not. In multiple regression analysis,
only low HDL cholesterol was found as an independent predictor for both arterial
stiffness and LV diastolic dysfunction. Enhanced arterial stiffness is
associated with LV diastolic dysfunction. Low HDL cholesterol may lead to the
deterioration of both arterial stiffness and LV diastolic function in patients
with essential hypertension"

increase in BP was observed in the first hour after caffeine intake and lasted
≥3 h. In 3 studies of the longer-term effect (2 wk) of coffee, no increase in BP
was observed after coffee was compared with a caffeine-free diet or was compared
with decaffeinated coffee. Last, 7 cohort studies found no evidence of an
association between habitual coffee consumption and a higher risk of CVD ... In
hypertensive individuals, caffeine intake produces an acute increase in BP for
≥3 h. However, current evidence does not support an association between
longer-term coffee consumption and increased BP or between habitual coffee
consumption and an increased risk of CVD in hypertensive subjects"

Midlife and
Late-Life Blood Pressure and Dementia in Japanese Elderly: The Hisayama Study
- Hypertension. 2011 May 9 - "We followed up a total of
668 community-dwelling Japanese individuals without dementia, aged 65 to 79
years, for 17 years and examined the associations of late-life and midlife
hypertension with the risk of vascular dementia and Alzheimer disease using the
Cox proportional hazards model ... The age- and sex-adjusted incidence of
vascular dementia significantly increased with elevated late-life blood pressure
levels (normal: 2.3, prehypertension: 8.4, stage 1 hypertension: 12.6, and stage
2 hypertension: 18.9 per 1000 person-years; P(trend)<0.001), whereas no such
association was observed for Alzheimer disease (P(trend)=0.88). After adjusting
for potential confounding factors, subjects with prehypertension and stage 1 or
stage 2 hypertension had 3.0-fold, 4.5-fold, and 5.6-fold greater risk of
vascular dementia, respectively, compared with subjects with normal blood
pressure. Likewise, there was a positive association of midlife blood pressure
levels with the risk of vascular dementia but not with the risk of Alzheimer
disease. Compared with those without hypertension in both midlife and late life,
subjects with midlife hypertension had an ≈5-fold greater risk of vascular
dementia, regardless of late-life blood pressure levels. Our findings suggest
that midlife hypertension and late-life hypertension are significant risk
factors for the late-life onset of vascular dementia but not for that of
Alzheimer disease in a general Japanese population. Midlife hypertension is
especially strongly associated with a greater risk of vascular dementia,
regardless of late-life blood pressure levels"

of Blood Pressure and Cardiovascular Events in the Pravastatin or Atorvastatin
Evaluation and Infection Therapy-Thrombolysis in Myocardial Infarction (PROVE
IT-TIMI) 22 Trial - Circulation. 2010 Nov 8 - "The
relationship between BP (systolic or diastolic) followed a J- or U-shaped curve
association with primary, secondary, and individual outcomes, with increased
events rates at both low and high BP values, both unadjusted and after
adjustment for baseline variables, baseline C-reactive protein, and on-treatment
average levels of low-density lipoprotein cholesterol. A nonlinear Cox
proportional hazards model showed a nadir of 136/85 mm Hg (range 130 to 140 mm
Hg systolic and 80 to 90 mm Hg diastolic) at which the incidence of primary
outcome was lowest. The curve was relatively flat for systolic pressures of 110
to 130 mm Hg and diastolic pressures of 70 to 90 mm Hg. Conclusions- After acute
coronary syndrome, a J- or U-shaped curve association existed between BP and the
risk of future cardiovascular events, with lowest event rates in the BP range of
approximately 130 to 140 mm Hg systolic and 80 to 90 mm Hg diastolic and a
relatively flat curve for systolic pressures of 110 to 130 mm Hg and diastolic
pressures of 70 to 90 mm Hg, which suggests that too low of a pressure

Persistence
of Mortality Reduction After the End of Randomized Therapy in Clinical Trials of
Blood Pressure-Lowering Medications - Hypertension. 2010 Oct 25 -
"We evaluated the persistence of mortality benefit of
these agents after the end of clinical trials, when all of the patients were
advised to take the same open-label therapy. We performed a meta-analysis of
randomized clinical trials using blood pressure-lowering medications, used in
patients with hypertension, myocardial infarction, or left ventricular systolic
dysfunction, (n=18; 132 854 patients; 11 988 deaths) when a second report
describing results after the end of the trial was available. During the
randomized (first) phase, 80% (interquartile range: 75% to 83%) of the patients
randomized to receive active therapy actually received it compared with 16%
(interquartile range: 7% to 22%) of those randomized to control. In this phase,
mortality was lower in the intervention group (odds ratio: 0.84 [95% CI: 0.79 to
0.90]; P<0.0001). Mortality was also lower during the open-label follow-up
(second) phase (odds ratio: 0.85 [95% CI: 0.79 to 0.91]; P<0.0001), when all of
the patients were advised to take the same therapy, and rates of receiving
active therapy were similar in the 2 groups (59% [interquartile range: 46% to
77%], among those originally randomized to active, and 43% [interquartile range:
20% to 68%], in the control). Several sensitivity analyses indicated stability
of the effects. In studies of antihypertensive medications, a decrease in
overall mortality persists after the end of trial phase, when most patients in
both the intervention and control groups receive active therapy. These analyses
imply that earlier intervention would result in better clinical outcomes"

a Japanese population: the Ibaraki Prefectural Health Study - Hypertens Res.
2010 Oct 7 - "Multivariate HRs (95% confidence interval)
associated with a 10 mm Hg increase in systolic BP were measured in 1993 and
1998, and their averages were 1.11 (1.05-1.16), 1.13 (1.07-1.18) and 1.17
(1.10-1.27), respectively. Multivariate HRs for a 10 mm Hg increase in
time-averaged systolic BP were 1.12 (1.03-1.21) in men and 1.24 (1.13-1.35) in
women. The subgroup analysis of antihypertensive use showed that multivariate
HRs for time-averaged systolic BP were 1.20 (1.11-1.29) in sustained non-users
and 1.17 (1.04-1.32) in sustained users. Similar results were also obtained for
diastolic BP. In conclusion, long-term exposure to elevated BP substantially
associates with excess risk for cardiovascular disease mortality among Japanese
subjects, irrespective of antihypertensive medication use. Thus, appropriate
management of BP is important in both users and non-users of antihypertensive
medication"

"The relationship between SBP or DBP and primary outcome
followed a J-curve with increased event rates above and below the reference BP
range, both unadjusted and adjusted (for baseline covariates, treatment effect,

hazard model identified a nadir of 146.3/81.4 mmHg where the event rate was
lowest. A similar non-linear relationship with a higher risk of events at lower
pressures was found for most of the secondary outcomes of all-cause mortality,
cardiovascular mortality, non-fatal MI, or angina. However, for the outcome of
stroke, lower was better for SBP. Conclusion In patients with CAD, a low BP
(<110-120/<60-70 mmHg) portends an increased risk of future cardiovascular

with those with SBP <120 mm Hg, untreated, and <50 years of age at baseline,
17.7% (95% CI: 4.6% to 29.1%) of the cases were attributable to prehypertensive

midlife, 27% (95% CI: 8.9% to 42.1%) of dementia cases can be attributed to
systolic BP >/=120 mm Hg, translating into 17 excess cases per 1000. Although

Prehypertension is associated with insulin resistance - QJM. 2009 Aug 7 -
"All subjects received a 75-g oral glucose tolerance
test (OGTT) for the measurements of IR. RESULTS: The prehypertensive subjects
were more obese and had higher levels of fasting triglycerides and 2-h insulin
than the normotensives. The subjects with prehypertension were more insulin
resistant than the counterparts, indicated by lower insulin sensitivity index,
ISI(0,120), values. While there was no difference between the two groups in
insulin response of OGTT after adjustments for confounders, the prehypertension
group maintained significant between-group differences in glucose response even
when the incremental insulin levels were added to covariates for adjustments.
DISCUSSION: Our data show that prehypertension is associated with IR. The
subjects with prehypertension have clinical characteristics of the IR syndrome.
It seems that the prehypertension group cannot handle oral glucose challenge as
well as the normotension, probably a consequence of IR in prehypertension"

without chronic heart failure affecting systolic function, mean arterial blood
pressure is largely determined by peripheral vasoconstriction, and higher
systolic pressure indicates poor elasticity of the arteries ... In patients with
heart failure, however, systolic pressure reflects the ejection fraction and
cardiac output ... a higher blood pressure is associated with a decreased
mortality as it serves as an indirect measure of cardiac function"
