TL;DR: It is concluded that ACE inhibition does not acutely impair K homeostasis in men with normal renal function and enalapril treatment.
Abstract: The effect of angiotensin-converting enzyme (ACE) inhibition on renal and extrarenal potassium (K) regulation was examined. Six healthy men were studied in double-blinded crossover fashion on placebo or enalapril, 80 mg/day. On day 4, the subjects were given an intravenous infusion of KCI and on day 5 an oral dose of 10% NH4Cl. Treatment with enalapril decreased plasma aldosterone and increased plasma renin activity (PRA), epinephrine and norepinephrine, but did not affect serum glucose, plasma insulin or basal plasma K. Maximal increases in plasma K during K infusion or NH4Cl ingestion were similar during enalapril and placebo treatment. With enalapril treatment urinary K excretion was unchanged following K loading but moderately reduced following NH4Cl loading. We conclude that ACE inhibition does not acutely impair K homeostasis in men with normal renal function.

TL;DR: In this group of normoalbuminuric type 2 diabetic patients, office and ambulatory PP were associated with duration of diabetes, indices of glycemic control and cardiovascular risk factors, and there was relationship between office and ambulance PP and albuminuria even within normal album inuria range.
Abstract: To investigate the association of office and ambulatory 24-h pulse pressure (PP) with clinical characteristics and cardiovascular risk factors in normoalbuminuric type 2 diabetic patients enrolled to the Randomised Olmesartan and Diabetes Microalbuminuria Prevention study, 4449 patients (2054 male and 2395 female; mean age 57.7±8.7 years) with type 2 diabetes, normoalbuminuria and at least one additional cardiovascular risk factor were included into the analysis. After adjustment by age, there were significant correlations between office PP and presence of hypertension (r=0.24; P<0.001), presence of cardiac and vascular disorders (r=0.17; P<0.001), metabolic syndrome (r=0.10; P<0.001), duration of diabetes (r=0.09; P<0.001), fasting blood glucose (r=0.08; P<0.001), albumin/creatinine ratio (r=0.07; P<0.001), insulin treatment, glycosylated haemoglobin (HbA1c), male gender and current smoking. In the subgroup of 1234 patients with ambulatory blood pressure measurement performed, ambulatory PP adjusted for office PP correlated with fasting blood glucose (r=0.16; P<0.001), metabolic syndrome (r=0.14; P<0.001), albumin/creatinine ratio (r=0.11; P<0.001) and indices of glycemic control (HbA1c: r=0.11; P<0.001). In this group of normoalbuminuric type 2 diabetic patients, office and ambulatory PP were associated with duration of diabetes, indices of glycemic control and cardiovascular risk factors. There was relationship between office and ambulatory PP and albuminuria even within normal albuminuria range.

TL;DR: Older compared to younger adults experienced less improvement in diastolic function in response to similar reductions in SBP, and this was not significantly different across age strata.
Abstract: Objective Diastolic dysfunction is associated with adverse outcomes and is highly prevalent among older adults with hypertension. Lowering SBP with antihypertensive therapy has been shown to improve diastolic function, but whether or not age influences this effect is unknown. Methods In the Exforge Intensive Control of Hypertension to Evaluate Efficacy in Diastolic Dysfunction trial, 189 patients (age range 45-93 years) with hypertension and diastolic dysfunction underwent echocardiography before and after 24 weeks of intensive versus standard antihypertensive therapy titrated to a goal SBP below 135 versus below 140 mmHg. We performed linear regression analyses to examine the association between age and improvement in diastolic function achieved with SBP reduction. Results Antihypertensive therapy reduced SBP by 28 ± 19 mmHg overall, and this was not significantly different across age strata. However, percentage improvement in diastolic relaxation velocity (lateral E' peak velocity) for every 10 mmHg reduction in SBP was lower in older compared to younger patients. In analyses adjusting for age stratum, sex, treatment arm, baseline relaxation velocity, and baseline blood pressure, older age was associated with reduced improvement in diastolic relaxation velocity per 10 mmHg of SBP reduction (β -1.64, P = 0.009). In contrast, the degree of change in left ventricular mass index per 10 mmHg reduction in SBP was not influenced by age (P = 0.89). Conclusions In our sample of individuals with hypertension and diastolic dysfunction, older compared to younger adults experienced less improvement in diastolic function in response to similar reductions in SBP.

TL;DR: The patterns of intra-daily variability produced by the two insulins in the group as a whole suggest that the daily distribution of insulin activity of lente insulin is similar to but slightly slower than that of NPH insulin, however, the twoinsulins may not always be directly interchangeable in the individual patient.

TL;DR: Why would an astute clinician (or informed patient) be satisfied with the relatively limited effects of any single class of antihypertensive agents when better overall protection is possible?
Abstract: In the prevention of hypertensive complications, especially stroke and kidney disease, “lower is better” because for each decrease of 20 mm Hg systolic or 10 mm Hg diastolic pressure in the population, cardiovascular risk is halved. Ideally, the goal for each patient should be to reach the lowest blood pressure that is well tolerated, a value that may be well below the arbitrary threshold value of 140/90 mm Hg. For the majority of “uncomplicated hypertensives,” the question of single-drug therapy is essentially moot, because more than one agent is almost always required to optimally control blood pressure. In individuals who already have heart or kidney disease, there are compelling indications for the use of drugs that block the renin-angiotensin system, but the large outcome studies that spawned these recommendations are themselves combination trials. Thus, in virtually all patients, more than one drug is indicated. The best combinations take advantage of long durations of action and complementary mechanisms of action of the component and are not only able to effectively lower blood pressure, but also to favorably affect the natural history of hypertensive complications. Regimens—including fixed-dose combination products—that combine a thiazide diuretic or calcium antagonist with an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker are most efficient. In summary, why would an astute clinician (or informed patient) be satisfied with the relatively limited effects of any single class of antihypertensive agents when better overall protection is possible?

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 …
