TL;DR: A meta-analysis of studies comparing diuretics, beta-blockers, calcium antagonists and/or angiotensin-converting enzyme (ACE) inhibitors suggests that the reduction of left ventricular mass with each of these classes is similar to the reduction obtained with the other three classes statistically combined.
Abstract: Although the development of left ventricular hypertrophy in hypertension is explained as a response to increases in pressure load and wall tension, the relationship between left ventricular mass and conventional blood pressure is usually weak. This may be due to the lack of standardization and the small number of blood pressure measurements in some studies. However, even 24-h blood pressure monitoring can explain only around 25% of the variation in left ventricular mass, and repeated blood pressure measurements over 30 years have not proved better in this respect. Therefore, other factors have been considered, including anthropometric and demographic characteristics; genetic influences; differences in salt intake, physical activity and alcohol consumption; neurohumoral factors; duration of hypertension; and previous antihypertensive treatment. Antihypertensive treatment may reduce left ventricular mass and a number of prospective, randomized, comparative studies have assessed whether some (classes of) drugs are more effective than others. A meta-analysis of such studies, comparing diuretics, beta-blockers, calcium antagonists and/or angiotensin-converting enzyme (ACE) inhibitors, suggests that the reduction of left ventricular mass with each of these classes is similar to the reduction obtained with the other three classes statistically combined. Of particular interest is the observation that the four studies which specifically compared an ACE inhibitor and a calcium antagonist concluded that their effects on left ventricular mass did not significantly differ. Furthermore, that agents such as minoxidil and hydralazine do not reduce left ventricular mass.

TL;DR: A high level of complaint was associated with female gender, increasing age, blood sugar and BMI and a low age of leaving education in elderly persons with isolated systolic hypertension.
Abstract: Objectives: to determine the symptomatic well-being of elderly persons with isolated systolic hypertension. Design and setting: well-being determined during the placebo run-in period prior to entry to the Systolic Hypertension in Europe (SYST-EUR) trial. Subjects: 641 people, 60 years or older with an average sitting blood pressure of 173/86 mmHg. Outcome measures: 33 symptomatic complaints determined by a standard interview. Results: the 437 women complained of 25% of the symptoms and the 204 men 21% (P < 0.001). A markedly higher prevalence was observed in women compared with men for: pain in the joints of the hands (35% of women complained of this against 22% of men); ‘racing heart’ (33% against 17%); dry eyes (16% against 6%); blurring of vision (35% against 23%); cramps in the legs (43% against 31%); and a sore throat (15% against 7%). Nocturia was the most frequent complaint (68% in both sexes). Eight symptoms increased with age and one (rash) tended to decline. With increasing systolic pressure women also reported more headaches, unsteadiness, blurring of vision, irregular heart beat and ‘racing heart’ but, of these, only headaches increased with diastolic pressure. These observations were made after adjusting for age, blood sugar and body mass index (BMI) and were not observed in men. Higher blood sugars were associated with mouth ulcers, ‘racing heart’, blurring of vision and cramps in the legs. A higher BMI was associated with six symptoms, and a lower age of leaving education with eight. In men, alcohol consumption was related to ‘racing heart’, and smoking to wheezing and having a dry cough. Conclusions: a high level of complaint was associated with female gender, increasing age, blood sugar and BMI and a low age of leaving education.

TL;DR: Exercise BP is not better related to target organ damage than BP at rest in patients with essential hypertension, and exercise BP did not contribute independently fromBP at rest to their variance.
Abstract: To study whether exercise blood pressure is more closely related to the complications of hypertension than resting blood pressure, 169 patients with essential hypertension, aged 16-66 years, (WHO stages I and II), underwent a graded uninterrupted exercise test on the bicycle ergometer up to exhaustion. BP was measured in intra-arterially. Target organ damage was assessed by eye-fundus grade and by electrocardiographic voltage criteria and T-wave patterns. After adjustment for relevant covariates (age, gender, body height and weight), the manifestations of target organ damage were significantly related to systolic (r ranging from 0.19 to 0.39) and diastolic (r ranging from 0.11 to 0.30) intra-arterial pressure at supine rest. The complications of hypertension were not more closely related to BP during upright submaximal and peak exercise than to resting BP, and exercise BP did not contribute independently from BP at rest to their variance. In conclusion, exercise BP is not better related to target organ damage than BP at rest in patients with essential hypertension.

TL;DR: Values of blood pressure in old patients with isolated systolic hypertension were more reproducible for ambulatory than they were for clinic measurements.
Abstract: OBJECTIVES: To compare clinic and am measurements of blood pressure in old patients with isolated systolic hypertension and their reproducibilities. PATIENTS: In total 610 patients aged >/= 60 years with isolated systolic hypertension detected by clinic measurement were monitored during the placebo run-in phase of the Syst-Eur trial. METHODS: The time-weighted 24 h blood pressure, clock-time day and night blood pressures, the cumulative-sum-derived crest and trough blood pressures and the high and low blood pressure levels according to the square-wave model were computed. The daily alteration between the high and low spans of blood pressure was quantified using the day-night difference, the cumulative-sum-derived magnitude of circadian alteration, the Fourier amplitude and the difference between the high and low blood pressure levels of the square-wave model. RESULTS: The daytime am systolic blood pressure was, on average, 21 mmHg lower than the clinic systolic blood pressure, whereas diastolic pressure was, on average, similar with both techniques of measurement. Clinic levels of blood pressure in the 141 patients who underwent repeat measurements and the parameters describing the difference between the daily high and low spans of blood pressure were equally reproducible. However, both were less reproducible than the ambulatory blood pressure levels. The reproducibility coefficients, expressed as percentages of near maximum variation, were 49 and 50% for the clinic systolic and diastolic blood pressures, 30 and 32% for the mean 24 h systolic and diastolic blood pressures and 45-55% for the parameters describing the daily alteration between the high and low spans of blood pressure. CONCLUSION: Values of blood pressure in old patients with isolated systolic hypertension were more reproducible for ambulatory than they were for clinic measurements. Levels in patients selected because they have a high clinic blood pressure may be substantially higher with conventional than they are with daytime ambulatory measurement. The prognostic significance of this difference for the present patients is currently under investigation.

TL;DR: It is recommended that everybody who is able should engage in regular aerobic physical activity, such as brisk walking, for at least 30 min per day most days of the week, as a means to lower blood pressure.
Abstract: Lifestyle modifications are advocated for the prevention, treatment and control of hypertension, with exercise being an integral component. Higher levels of physical activity and greater fitness are associated with a reduced incidence of hypertension [1]. Furthermore, a number of studies with well-controlled randomized experimental designs, examining the effects of aerobic endurance training programmes in hypertension, generally demonstrate training to exert a significant antihypertensive effect [2,3]. Recent guidelines therefore recommend that everybody who is able should engage in regular aerobic physical activity, such as brisk walking, for at least 30 min per day most days of the week, as a means to lower blood pressure [1,4].

TL;DR: It is recommended that spirometry is required for the clinical diagnosis of COPD to avoid misdiagnosis and to ensure proper evaluation of severity of airflow limitation.
Abstract: Chronic obstructive pulmonary disease (COPD) remains a major public health problem. It is the fourth leading cause of chronic morbidity and mortality in the United States, and is projected to rank fifth in 2020 in burden of disease worldwide, according to a study published by the World Bank/World Health Organization. Yet, COPD remains relatively unknown or ignored by the public as well as public health and government officials. In 1998, in an effort to bring more attention to COPD, its management, and its prevention, a committed group of scientists encouraged the U.S. National Heart, Lung, and Blood Institute and the World Health Organization to form the Global Initiative for Chronic Obstructive Lung Disease (GOLD). Among the important objectives of GOLD are to increase awareness of COPD and to help the millions of people who suffer from this disease and die prematurely of it or its complications. The first step in the GOLD program was to prepare a consensus report, Global Strategy for the Diagnosis, Management, and Prevention of COPD, published in 2001. The present, newly revised document follows the same format as the original consensus report, but has been updated to reflect the many publications on COPD that have appeared. GOLD national leaders, a network of international experts, have initiated investigations of the causes and prevalence of COPD in their countries, and developed innovative approaches for the dissemination and implementation of COPD management guidelines. We appreciate the enormous amount of work the GOLD national leaders have done on behalf of their patients with COPD. Despite the achievements in the 5 years since the GOLD report was originally published, considerable additional work is ahead of us if we are to control this major public health problem. The GOLD initiative will continue to bring COPD to the attention of governments, public health officials, health care workers, and the general public, but a concerted effort by all involved in health care will be necessary.

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 document provides updated normal values for all four cardiac chambers, including three-dimensional echocardiography and myocardial deformation, when possible, on the basis of considerably larger numbers of normal subjects, compiled from multiple databases.
Abstract: The rapid technological developments of the past decade and the changes in echocardiographic practice brought about by these developments have resulted in the need for updated recommendations to the previously published guidelines for cardiac chamber quantification, which was the goal of the joint writing group assembled by the American Society of Echocardiography and the European Association of Cardiovascular Imaging. This document provides updated normal values for all four cardiac chambers, including three-dimensional echocardiography and myocardial deformation, when possible, on the basis of considerably larger numbers of normal subjects, compiled from multiple databases. In addition, this document attempts to eliminate several minor discrepancies that existed between previously published guidelines.
