TL;DR: Crystalline valsartan/sacubitril 400 mg daily is superior to valartan 320 mg daily for lowering SBP, has similar efficacy to the combination of free valsArtan 320mg plus free sacubitrill 200 mg, represents the optimal dosage for systolic hypertension in patients of any age, and is safe and well tolerated.
Abstract: We compared the systolic blood pressure (SBP)-lowering efficacy and safety of crystalline valsartan/sacubitril (LCZ696, an angiotensin receptor blocker-neprilysin inhibitor) 400 mg daily against valsartan (320 mg once daily) alone or coadministered with placebo or increasing doses of free sacubitril (50, 100, 200, or 400 mg once daily) to identify the optimal antihypertensive combination dose. This multicenter, double-blinded, 7-arm parallel-group study recruited patients with mild-to-moderate systolic hypertension (office SBP 150-179 mm Hg). Primary-dependent variable was change in office SBP from baseline to week 8. At entry (n = 907), mean age was 61.5 years, sitting office BP 160/90.2 mm Hg, and mean 24-hour ambulatory BP 142/82.1 mm Hg; 852 participants completed the study. At week 8, there were greater reductions in sitting office SBP and 24-hour ambulatory SBP with LCZ696 400 mg than with valsartan 320 mg (-5.7 and -3.4 mm Hg, respectively, P < 0.05 each). The SBP reduction with LCZ696 400 daily was similar to coadministered free valsartan 320 mg and sacubitril 200 mg. Effects were similar in those older and younger than 65 years, and active therapies had adverse event rates similar to placebo. We conclude that crystalline valsartan/sacubitril 400 mg daily (1) is superior to valsartan 320 mg daily for lowering SBP, (2) has similar efficacy to the combination of free valsartan 320 mg plus free sacubitril 200 mg, (3) represents the optimal dosage for systolic hypertension in patients of any age, and (4) is safe and well tolerated.

TL;DR: It is suggested that expansion of extracellular fluid and activation of the sympathetic nervous system oppose the hemodynamic effects of prazosin.
Abstract: Prazosin was given for 10 to 14 days to eight hypertensive patients on a fixed intake of dietary salt. Except as limited by side effects, the dose was increased from 2 mg/day to a maximum dose of 24 mg/day. During treatment, when subjects were studied in supine and upright positions, mean arterial pressure (MAP) fell 6% and 12% (p < 0.025 and p < 0.005), heart rate rose 3% and 9% (p < 0.05 and p < 0.005), and plasma norepinephrine increased 95% and 107% (p < 0.01 and p < 0.001) over control. Daily excretion of the norepinephrine metabolites methoxyhydroxyphenyl glycol (MHPG) and vanillylmandelic acid (VMA) increased 42% and 17% (p < 0.05 for each) during treatment. There were no changes in average body weight or plasma renin for the group, but patients whose body weight increased tended to show less reduction in blood pressure (correlation coefficient, r = 0.72, p < 0.05) and smaller increases in heart rate (r = −0.73, p < 0.05) during treatment with prazosin. These data suggest that expansion of extracellular fluid and activation of the sympathetic nervous system oppose the hemodynamic effects of prazosin.

TL;DR: Nearly everything that modern practicing clinicians know about hypertension and its treatment is based on simple noninvasive measurement of brachial artery blood pressure, however, additional knowledge of pulse-wave characteristics may be important in the future to fully assess optimal cardiovascular drug therapy.
Abstract: Nearly everything that modern practicing clinicians know about hypertension and its treatment is based on simple noninvasive measurement of brachial artery blood pressure. As the study by Williams and colleagues1 illustrates, however, additional knowledge of pulse-wave characteristics may be important in the future to fully assess optimal cardiovascular drug therapy.
The study of pulse-wave characteristics is far older than the study of absolute pressure values, dating back thousands of years to the Chinese masters who used their fingertips and their powers of observation to associate “hardening of the pulse” with adverse outcomes in people who ingested too much salt. These qualitative observations were less well developed in Western medicine, but as early as the 1870s, the sphygmocardiogram was developed as a reproduction of a peripheral pulse wave on a rotating drum via a tonometer attached to a levered stylus.1a Morrell and other early investigators were clearly able to differentiate the effects of nitrovasodilators from digitalis using this early equipment, but interpretations remained largely qualitative. Within a few decades, the development of sphygmomanometry by Korotkovand Riva-Rocci allowed quantitation of brachial cuff blood pressures, and the more descriptive methods largely disappeared.
Article p 1213
Indeed, brachial cuff blood pressure has become an enduring clinical variable. Actuarial data from the life insurance industry and subsequent prospective observational data have clearly shown that hypertension, or elevated cuff blood pressure, is closely related to many forms of cardiovascular disease.2–4 Most recently, a very large meta-analysis by the Prospective Studies Collaborators that involved almost 1 million persons enrolled in 61 prospective observational studies demonstrated a log-linear relationship between cuff systolic or diastolic blood …

TL;DR: For hypertensive patients not controlled by lisinopril 20mg once daily, addition of candesartan (32 mg once daily) or doubling the dose of lisinobril provides safe, additional reduction of blood pressure.
Abstract: The AMAZE (A Multicenter Trial Using Atacand and Zestril vs. Zestril to Evaluate the Effects on Lowering Blood Pressure) program included two identical studies sponsored by AstraZeneca LP. The oral form of candesartan is candesartan cilexetil; for simplicity, the term "candesartan" is used throughout this manuscript. Two identical multicenter, randomized, double-blind studies were performed to determine if addition of the angiotensin receptor blocker candesartan was more effective in lowering blood pressure than up-titration of lisinopril. Hypertensive patients (N=1,096) who were uncontrolled on lisinopril 20 mg daily were randomized (1:1) to receive either 8 weeks of high-dose lisinopril (40 mg) or the addition of candesartan (16 mg) for 2 weeks followed by 32 mg for 6 weeks. Study 1 (n=538) demonstrated decreases in trough sitting systolic/diastolic blood pressures at Week 8 by 6.2/5.9 mm Hg, respectively, for the lisinopril up-titration treatment group and by 11.6/8.3 mm Hg, respectively, for the lisinopril plus candesartan treatment group (p<0.01 in comparing both blood pressures reductions between the two treatment groups). Corresponding results for Study 2 (n=558) are reductions of 8.7/6.2 mm Hg and 9.5/7.4 mm Hg, respectively, for each of the two treatment groups. For Study 2, comparisons of systolic/diastolic blood pressures between the two treatment groups were not statistically significantly different (p=0.51/p=0.08, respectively). Post hoc pooled analysis (N=1,096) demonstrated a slightly greater blood pressure reduction with lisinopril plus candesartan compared with lisinopril (3.1/1.7 mm Hg). A 95% confidence interval limit for the difference in least squares mean change from baseline in systolic blood pressure between the two treatment groups is -4.8 to -1.5 and is -2.8 to -0.7 in mm Hg for diastolic blood pressure. The blood pressure control rates (<140/<90 mm Hg) were 42.7% and 36.9%, respectively. Both treatment regimens were well tolerated in all groups. In conclusion, for hypertensive patients not controlled by lisinopril 20 mg once daily, addition of candesartan (32 mg once daily) or doubling the dose of lisinopril provides safe, additional reduction of blood pressure.

TL;DR: In participants with hypertension and diabetes, triple- Combination treatment led to greater BP reductions and enabled greater proportions of participants to reach BP goal versus the dual-combination treatments.
Abstract: Background Most patients with hypertension and diabetes require two or more antihypertensive agents to achieve the recommended blood pressure (BP) goal of TRI ple Therapy with Olmesartan Medoxomil, Amlodipine, and Hydrochlorothiazide in HyperteNsIve PatienTs StudY assessed the efficacy and safety of triple-combination treatment (olmesartan medoxomil 40/amlodipine besylate 10/hydrochlorothiazide 25 mg) versus the component dual-combination treatments according to diabetes status (diabetes; non-diabetes). Methods Participants received dual-combination treatment for 4 weeks or placebo for 2 weeks. Participants receiving placebo switched to dual-combination treatment from week 2 to week 4. At week 4, participants switched to triple-combination treatment or continued on dual-combination treatment until week 12. Results The prespecified changes in BP from baseline for the diabetes subgroup receiving triple-combination treatment were greater than the respective dual-combination treatments ( P ≤ .0013). Also, more participants with diabetes receiving triple-combination treatment reached BP goal ( P ≤ .0092). In a post hoc analysis, significantly greater proportions of study participants with diabetes achieved BP targets with triple-combination treatment compared with each dual-combination treatment. Most treatment-emergent adverse events were mild to moderate in severity. Conclusions In participants with hypertension and diabetes, triple-combination treatment led to greater BP reductions and enabled greater proportions of participants to reach BP goal versus the dual-combination treatments. Triple-combination treatment was well tolerated in both diabetes and non-diabetes subgroups.

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.

TL;DR: This statement from the American Heart Association and the National Heart, Lung, and Blood Institute is intended to provide up-to-date guidance for professionals on the diagnosis and management of the metabolic syndrome in adults.
Abstract: The metabolic syndrome has received increased attention in the past few years. This statement from the American Heart Association (AHA) and the National Heart, Lung, and Blood Institute (NHLBI) is intended to provide up-to-date guidance for professionals on the diagnosis and management of the metabolic syndrome in adults.
The metabolic syndrome is a constellation of interrelated risk factors of metabolic origin— metabolic risk factors —that appear to directly promote the development of atherosclerotic cardiovascular disease (ASCVD).1 Patients with the metabolic syndrome also are at increased risk for developing type 2 diabetes mellitus. Another set of conditions, the underlying risk factors , give rise to the metabolic risk factors. In the past few years, several expert groups have attempted to set forth simple diagnostic criteria to be used in clinical practice to identify patients who manifest the multiple components of the metabolic syndrome. These criteria have varied somewhat in specific elements, but in general they include a combination of both underlying and metabolic risk factors.
The most widely recognized of the metabolic risk factors are atherogenic dyslipidemia, elevated blood pressure, and elevated plasma glucose. Individuals with these characteristics commonly manifest a prothrombotic state and a pro-inflammatory state as well. Atherogenic dyslipidemia consists of an aggregation of lipoprotein abnormalities including elevated serum triglyceride and apolipoprotein B (apoB), increased small LDL particles, and a reduced level of HDL cholesterol (HDL-C). The metabolic syndrome is often referred to as if it were a discrete entity with a single cause. Available data suggest that it truly is a syndrome, ie, a grouping of ASCVD risk factors, but one that probably has more than one cause. Regardless of cause, the syndrome identifies individuals at an elevated risk for ASCVD. The magnitude of the increased risk can vary according to which components of the syndrome are …
