TL;DR: The state of congestive heart failure is associated with clear-cut depressions of intrinsic myocardial function, and although the failing heart converts energy to work at a normal efficiency, the rate is decreased, which may be caused by a reduction of the activity of myofibrillar adenosine triphosphatase.
Abstract: The state of congestive heart failure is associated with clear-cut depressions of intrinsic myocardial function. The production and storage of energy in the failing heart are normal, and although the failing heart converts energy to work at a normal efficiency, the rate of this process is decreased. This decreased rate may be caused by a reduction of the activity of myofibrillar adenosine triphosphatase, which in turn may be causally related to the depression of cardiac function. In considering the efficiency of the failing heart, the translation of myocardial tension into useful circulatory work must also be considered. In this case, efficiency could be reduced by geometric factors such as ventricular size and shape and wall thickness or asynchrony of contraction. Finally, the failing heart must depend on supporting mechanisms, such as adrenergic stimulation, for normal function, and in the presence of reduced intrinsic norepinephrine stores, the presence of circulating catecholamines may be important.

TL;DR: In this article, the authors investigated whether patients with atrial fibrillation demonstrate detectable changes in biomarkers including high-sensitivity troponin T (hsTnT), N-terminal B-type natriuretic peptide (NT-proBNP), and growth differentiation factor-15 (GDF-15) over 12 months and whether such changes from baseline to 12 months are associated with the subsequent risk of stroke or systemic embolic events (S/SEE) and bleeding.
Abstract: Aims We investigated whether patients with atrial fibrillation (AF) demonstrate detectable changes in biomarkers including high-sensitivity troponin T (hsTnT), N-terminal B-type natriuretic peptide (NT-proBNP), and growth differentiation factor-15 (GDF-15) over 12 months and whether such changes from baseline to 12 months are associated with the subsequent risk of stroke or systemic embolic events (S/SEE) and bleeding. Methods and results ENGAGE AF-TIMI 48 was a randomized trial of the oral factor Xa inhibitor edoxaban in patients with AF and a CHADS2 score of ≥2. We performed a nested prospective biomarker study in 6308 patients, analysing hsTnT, NT-proBNP, and GDF-15 at baseline and 12 months. hsTnT was dynamic in 46.9% (≥2 ng/L change), NT-proBNP in 51.9% (≥200 pg/mL change), GDF-15 in 45.6% (≥300 pg/mL change) during 12 months. In a Cox regression model, upward changes in log2-transformed hsTnT and NT-proBNP were associated with increased risk of S/SEE [adjusted hazard ratio (adj-HR) 1.74; 95% confidence interval (CI) 1.36-2.23 and adj-HR 1.27; 95% CI 1.07-1.50, respectively] and log2-transformed GDF-15 with bleeding (adj-HR 1.40; 95% CI 1.02-1.92). Reassessment of ABC-stroke (age, prior stroke/transient ischaemic attack, hsTnT, and NT-proBNP) and ABC-bleeding (age, prior bleeding, haemoglobin, hsTnT, and GDF-15) risk scores at 12 months accurately reclassified a significant proportion of patients compared with their baseline risk [net reclassification improvement (NRI) 0.50; 95% CI 0.36-0.65; NRI 0.42; 95% CI 0.33-0.51, respectively]. Conclusion Serial assessment of hsTnT, NT-proBNP, and GDF-15 revealed that a substantial proportion of patients with AF had dynamic values. Greater increases in these biomarkers measured over 1 year are associated with important clinical outcomes in anticoagulated patients with AF.

TL;DR: The frequency distribution of the TIMI Risk Score, or similar tools for risk assessment, may be used to quantify and readily compare the risk profile of populations enrolled in clinical studies.
Abstract: Aims Interpreting the results and practice implications of clinical studies requires accurate characterisation of the baseline risk of the population. We evaluated the Thrombolysis in Myocardial Infarction (TIMI) risk score for STEMI as a tool to describe and compare the risk profile of populations enrolled in three clinical trials (InTIME-II, ASSENT-2 and MAGIC) and the National Registry of Myocardial Infarction. Methods and Results The risk score was calculated for each patient \batchmode \documentclass[fleqn,10pt,legalpaper]{article} \usepackage{amssymb} \usepackage{amsfonts} \usepackage{amsmath} \pagestyle{empty} \begin{document} \((N=121,085)\) \end{document} and the frequency distribution plotted for each population. The Risk Score Profiles were compared using the Kolmogorov–Smirnov test. The Risk Score Profile demonstrated a striking concordance between the baseline risk of patients in InTIME-II and ASSENT-2 (median scores in each=\batchmode \documentclass[fleqn,10pt,legalpaper]{article} \usepackage{amssymb} \usepackage{amsfonts} \usepackage{amsmath} \pagestyle{empty} \begin{document} \(3[1,4]\) \end{document}, \batchmode \documentclass[fleqn,10pt,legalpaper]{article} \usepackage{amssymb} \usepackage{amsfonts} \usepackage{amsmath} \pagestyle{empty} \begin{document} \(P=0.11)\) \end{document}. In contrast, the distributions in MAGIC (designed to enroll high risk) and NRMI (registry) were shifted significantly toward higher risk (median scores=\batchmode \documentclass[fleqn,10pt,legalpaper]{article} \usepackage{amssymb} \usepackage{amsfonts} \usepackage{amsmath} \pagestyle{empty} \begin{document} \(4[3,5]\) \end{document} for MAGIC and \batchmode \documentclass[fleqn,10pt,legalpaper]{article} \usepackage{amssymb} \usepackage{amsfonts} \usepackage{amsmath} \pagestyle{empty} \begin{document} \(4[2,6]\) \end{document} in NRMI, \batchmode \documentclass[fleqn,10pt,legalpaper]{article} \usepackage{amssymb} \usepackage{amsfonts} \usepackage{amsmath} \pagestyle{empty} \begin{document} \(P{<}0.0001\) \end{document} for each vs. InTIME-II).

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: Atherosclerosis is an inflammatory disease as discussed by the authors, and it is a major cause of death in the United States, Europe, and much of Asia, despite changes in lifestyle and use of new pharmacologic approaches to lower plasma cholesterol concentrations.
Abstract: Atherosclerosis is an inflammatory disease. Because high plasma concentrations of cholesterol, in particular those of low-density lipoprotein (LDL) cholesterol, are one of the principal risk factors for atherosclerosis,1 the process of atherogenesis has been considered by many to consist largely of the accumulation of lipids within the artery wall; however, it is much more than that. Despite changes in lifestyle and the use of new pharmacologic approaches to lower plasma cholesterol concentrations,2,3 cardiovascular disease continues to be the principal cause of death in the United States, Europe, and much of Asia.4,5 In fact, the lesions of atherosclerosis represent . . .

TL;DR: Lifetime prevalence estimates are higher in recent cohorts than in earlier cohorts and have fairly stable intercohort differences across the life course that vary in substantively plausible ways among sociodemographic subgroups.
Abstract: Context Little is known about lifetime prevalence or age of onset of DSM-IV disorders. Objective To estimate lifetime prevalence and age-of-onset distributions of DSM-IV disorders in the recently completed National Comorbidity Survey Replication. Design and Setting Nationally representative face-to-face household survey conducted between February 2001 and April 2003 using the fully structured World Health Organization World Mental Health Survey version of the Composite International Diagnostic Interview. Participants Nine thousand two hundred eighty-two English-speaking respondents aged 18 years and older. Main Outcome Measures Lifetime DSM-IV anxiety, mood, impulse-control, and substance use disorders. Results Lifetime prevalence estimates are as follows: anxiety disorders, 28.8%; mood disorders, 20.8%; impulse-control disorders, 24.8%; substance use disorders, 14.6%; any disorder, 46.4%. Median age of onset is much earlier for anxiety (11 years) and impulse-control (11 years) disorders than for substance use (20 years) and mood (30 years) disorders. Half of all lifetime cases start by age 14 years and three fourths by age 24 years. Later onsets are mostly of comorbid conditions, with estimated lifetime risk of any disorder at age 75 years (50.8%) only slightly higher than observed lifetime prevalence (46.4%). Lifetime prevalence estimates are higher in recent cohorts than in earlier cohorts and have fairly stable intercohort differences across the life course that vary in substantively plausible ways among sociodemographic subgroups. Conclusions About half of Americans will meet the criteria for a DSM-IV disorder sometime in their life, with first onset usually in childhood or adolescence. Interventions aimed at prevention or early treatment need to focus on youth.

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.
