BACKGROUND: Reliable and timely information on the leading causes of death in populations, and how these are changing, is a crucial input into health policy debates. In the Global Burden of Diseases, Injuries, and Risk Factors Study 2010 (GBD 2010), we aimed to estimate annual deaths for the world and 21 regions between 1980 and 2010 for 235 causes, with uncertainty intervals (UIs), separately by age and sex.

METHODS: We attempted to identify all available data on causes of death for 187 ...

BACKGROUND: Measuring disease and injury burden in populations requires a composite metric that captures both premature mortality and the prevalence and severity of ill-health. The 1990 Global Burden of Disease study proposed disability-adjusted life years (DALYs) to measure disease burden. No comprehensive update of disease burden worldwide incorporating a systematic reassessment of disease and injury-specific epidemiology has been done since the 1990 study. We aimed to calculate ...

BACKGROUND: Non-fatal health outcomes from diseases and injuries are a crucial consideration in the promotion and monitoring of individual and population health. The Global Burden of Disease (GBD) studies done in 1990 and 2000 have been the only studies to quantify non-fatal health outcomes across an exhaustive set of disorders at the global and regional level. Neither effort quantified uncertainty in prevalence or years lived with disability (YLDs).

METHODS: Of the 291 diseases and ...

IMPORTANCE: Understanding the major health problems in the United States and how they are changing over time is critical for informing national health policy.

OBJECTIVES: To measure the burden of diseases, injuries, and leading risk factors in the United States from 1990 to 2010 and to compare these measurements with those of the 34 countries in the Organisation for Economic Co-operation and Development (OECD) countries.

DESIGN: We used the systematic analysis of descriptive epidemiology ...

CONTEXT: New-onset atrial fibrillation (AF) has been reported in 6% to 20% of patients with severe sepsis. Chronic AF is a known risk factor for stroke and death, but the clinical significance of new-onset AF in the setting of severe sepsis is uncertain.

OBJECTIVE: To determine the in-hospital stroke and in-hospital mortality risks associated with new-onset AF in patients with severe sepsis.

DESIGN AND SETTING: Retrospective population-based cohort of California State Inpatient Database ...

BACKGROUND: Asymmetric dimethylarginine (ADMA), an endogenous inhibitor of nitric oxide synthase, induces endothelial dysfunction. Although elevated ADMA has been associated with an increased risk of cardiovascular disease events and death in referral samples, the prognostic significance of ADMA in the community has not been adequately evaluated.

METHODS AND RESULTS: We related plasma ADMA, l-arginine (Arg), and the ratio of Arg to ADMA to the incidence of cardiovascular disease (fatal ...

BACKGROUND: Comprehensive long-term data on atrial fibrillation trends in men and women are scant. We aimed to provide such data through analysis of the Framingham cohort over 50 years.

METHODS: We investigated trends in incidence, prevalence, and risk factors for atrial fibrillation and its association with stroke and mortality after onset in 9511 participants enrolled in the Framingham Heart Study between 1958 and 2007. We analysed trends within 10 year groups (1958-67, 1968-77, ...

Importance: Nearly half of all patients with heart failure have preserved ejection fraction (HFpEF) as opposed to reduced ejection fraction (HFrEF), yet associations of biomarkers with future heart failure subtype are incompletely understood.

Objective: To evaluate the associations of 12 cardiovascular biomarkers with incident HFpEF vs HFrEF among adults from the general population.

Design, Setting, and Participants: This study included 4 longitudinal community-based cohorts: the ...

BACKGROUND: Measurement of the global burden of disease with disability-adjusted life-years (DALYs) requires disability weights that quantify health losses for all non-fatal consequences of disease and injury. There has been extensive debate about a range of conceptual and methodological issues concerning the definition and measurement of these weights. Our primary objective was a comprehensive re-estimation of disability weights for the Global Burden of Disease Study 2010 through a ...

BACKGROUND: The natriuretic peptides are counterregulatory hormones involved in volume homeostasis and cardiovascular remodeling. The prognostic significance of plasma natriuretic peptide levels in apparently asymptomatic persons has not been established.

METHODS: We prospectively studied 3346 persons without heart failure. Using proportional-hazards regression, we examined the relations of plasma B-type natriuretic peptide and N-terminal pro-atrial natriuretic peptide to the risk of ...

CONTEXT: Several reports have suggested the usefulness of plasma brain natriuretic peptide (BNP) as a screening test for left ventricular hypertrophy (LVH) and systolic dysfunction (LVSD). Prior studies were limited by small sample sizes and selection bias and none compared the diagnostic performance of these peptides in men and women.

OBJECTIVES: To examine the usefulness of natriuretic peptides for screening for elevated LV mass and LVSD in the community.

DESIGN, SETTING, AND ...

BACKGROUND: Heart failure is a major public health problem. Long-term trends in the incidence of heart failure and survival after its onset in the community have not been characterized.

METHODS: We used statistical models to assess temporal trends in the incidence of heart failure and Cox proportional-hazards regression to evaluate survival after the onset of heart failure among subjects in the Framingham Heart Study. Cases of heart failure were classified according to the date of onset: ...

BACKGROUND: Previous clinical studies have suggested that there is an association between mitral annular calcification and the risk of stroke, but it is unclear whether this association is independent of the traditional risk factors for stroke. We examined the relation between mitral annular calcification and the incidence of stroke in a population-based study.

METHODS: Subjects in the Framingham Study receiving a routine examination underwent M-mode echocardiography to determine the ...

BACKGROUND: Hyperuricaemia, a highly heritable trait, is a key risk factor for gout. We aimed to identify novel genes associated with serum uric acid concentration and gout.

METHODS: Genome-wide association studies were done for serum uric acid in 7699 participants in the Framingham cohort and in 4148 participants in the Rotterdam cohort. Genome-wide significant single nucleotide polymorphisms (SNPs) were replicated in white (n=11 024) and black (n=3843) individuals who took part in the ...

CONTEXT: Vascular stiffness increases with advancing age and is a major risk factor for age-related morbidity and mortality. Vascular stiffness and blood pressure pulsatility are related; however, temporal relationships between vascular stiffening and blood pressure elevation have not been fully delineated.

OBJECTIVE: To examine temporal relationships among vascular stiffness, central hemodynamics, microvascular function, and blood pressure progression.

DESIGN, SETTING, AND PARTICIPANTS: ...
