Heart Disease and Stroke Statistics-2020 Update: A Report From the American Heart Association.

BACKGROUND: The American Heart Association, in conjunction with the National Institutes of Health, annually reports on the most up-to-date statistics related to heart disease, stroke, and cardiovascular risk factors, including core health behaviors (smoking, physical activity, diet, and weight) and health factors (cholesterol, blood pressure, and glucose control) that contribute to cardiovascular health. The Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, congenital heart disease, rhythm disorders, subclinical atherosclerosis, coronary heart disease, heart failure, valvular disease, venous disease, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs). METHODS: The American Heart Association, through its Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States to provide the most current information available in the annual Statistical Update. The 2020 Statistical Update is the product of a full year's worth of effort by dedicated volunteer clinicians and scientists, committed government professionals, and American Heart Association staff members. This year's edition includes data on the monitoring and benefits of cardiovascular health in the population, metrics to assess and monitor healthy diets, an enhanced focus on social determinants of health, a focus on the global burden of cardiovascular disease, and further evidence-based approaches to changing behaviors, implementation strategies, and implications of the American Heart Association's 2020 Impact Goals. RESULTS: Each of the 26 chapters in the Statistical Update focuses on a different topic related to heart disease and stroke statistics. CONCLUSIONS: The Statistical Update represents a critical resource for the lay public, policy makers, media professionals, clinicians, healthcare administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.

Platelet Inhibitors Reduce Rupture in a Mouse Model of Established Abdominal Aortic Aneurysm.

OBJECTIVE: Rupture of abdominal aortic aneurysms causes a high morbidity and mortality in the elderly population. Platelet-rich thrombi form on the surface of aneurysms and may contribute to disease progression. In this study, we used a pharmacological approach to examine a role of platelets in established aneurysms induced by angiotensin II infusion into hypercholesterolemic mice. APPROACH AND RESULTS: Administration of the platelet inhibitors aspirin or clopidogrel bisulfate to established abdominal aortic aneurysms dramatically reduced rupture. These platelet inhibitors reduced abdominal aortic platelet and macrophage recruitment resulting in decreased active matrix metalloproteinase-2 and matrix metalloproteinase-9. Platelet inhibitors also resulted in reduced plasma concentrations of platelet factor 4, cytokines, and components of the plasminogen activation system in mice. To determine the validity of these findings in human subjects, a cohort of aneurysm patients were retrospectively analyzed using developed and validated algorithms in the electronic medical record database at Vanderbilt University. Similar to mice, administration of aspirin or P2Y12 inhibitors was associated with reduced death among patients with abdominal aortic aneurysm. CONCLUSIONS: These results suggest that platelets contribute to abdominal aortic aneurysm progression and rupture.

From Data to Action: Neuroepidemiology Informs Implementation Research for Global Stroke Prevention and Treatment.

As a scientific field of study, neuroepidemiology encompasses more than just the descriptive study of the frequency, distribution, determinants and outcomes of neurologic diseases in populations. It also includes experimental aspects that span the full spectrum of clinical and population science research. As such, neuroepidemiology has a strong potential to inform implementation research for global stroke prevention and treatment. This review begins with an overview of the progress that has been made in descriptive and experimental neuroepidemiology over the past quarter century with emphasis on standards for evidence generation, critical appraisal of that evidence and impact on clinical and public health practice at the national, regional and global levels. Specific advances made in high-income countries as well as in low- and middle-income countries are presented. Gaps in implementation as well as evidence gaps in stroke research, stroke burden, clinical outcomes and disparities between developed and developing countries are then described. The continuing need for high quality neuroepidemiologic data in low- and middle-income countries is highlighted. Additionally, persisting disparities in stroke burden and care by sex, race, ethnicity, income and socioeconomic status are discussed. The crucial role that national stroke registries have played in neuroepidemiologic research is also addressed. Opportunities presented by new directions in comparative effectiveness and implementation research are discussed as avenues for turning neuroepidemiological insights into action to maximize health impact and to guide further biomedical research on neurological diseases.

Carotid adventitial vasa vasorum and intima-media thickness in a primary prevention population.

BACKGROUND: Vasa vasorum (VV) vessels are critical in the genesis of atherosclerosis. Therefore, we assessed measures of carotid VV, intima-media thickness (CIMT), and patient risk factors in a primary prevention population. METHODS: We used multivariable linear models to evaluate the relationship between baseline covariates and a measure of carotid VV (VV ratio) and CIMT among 324 diabetics and 141 nondiabetics. RESULTS: Median CIMT (in mm) and VV ratio among nondiabetics were 0.82 ± 0.22 and 0.80 ± 0.19, respectively, and 1.06 ± 0.19 and 1.21 ± 0.26 among diabetics (P < 0.0001). Diabetes was associated with 36% (95% CI: 24.3-48.0, P < 0.001) higher VV ratio whereas a unit change in BMI was associated with ≈1% (95% CI: 0.5-1.4, P < 0.001) change in VV ratio. A 10-year increase in age was associated with 4% (95% CI: 1-7, P = 0.005) higher CIMT. Each 10 mmHg increase in mean systolic blood pressure was associated with 2% (95% CI: 1-4, P = 0.003) higher CIMT whereas diabetes conferred 31% (95% CI: 19.1-42.1, P < 0.001) higher CIMT. Female sex was associated with a 9% (95% CI: -12.9 to -4.1, P < 0.001) lower CIMT. Low density lipoprotein (LDL) cholesterol, blood pressure, and CIMT were not significantly associated with VV ratio. CONCLUSION: In this cohort of patients with low CIMT, VV ratio, and CIMT were distinctly unrelated, but each independently associated with diabetes. VV ratio and CIMT relationships warrant further investigation in large-scale studies and across a spectrum of atherosclerostic states.

Short-term trends in heart failure-related hospitalizations in a high-risk state.

OBJECTIVES: We sought to determine whether there are signs of improvement in the rates of heart failure (HF) hospitalizations given the recent reports of improvement in national trends. METHODS: HF admissions data from the Tennessee Hospital Discharge Data System were analyzed. RESULTS: Hospitalization for primary diagnosis of HF (HFPD) in adults (aged 20 years old or older) decreased from 4.5% in 2006 to 4.2% in 2008. Similarly, age-adjusted HF hospitalization (per 10,000 population) declined by 19.1% (from 45.5 in 2006 to 36.8 in 2008). The age-adjusted rates remain higher among blacks than whites and higher among men than women. Notably, the rate ratio of black-to-white men ages 20 to 34 years admitted with HFPD increased from 8.5 in 2006 to 11.1 in 2008; similarly, the adjusted odds ratios for HFPD were 4.75 (95% confidence interval 3.29-6.86) and 5.61 (95% confidence interval 3.70-8.49), respectively. There was, however, a significant improvement in odds ratio for HF rates among young black women, as evidenced by a decrease from 4.60 to 3.97 (aged 20-34 years) and 4.21 to 3.12 (aged 35-44 years) between 2006 and 2008, respectively. Among patients aged 20 to 34 and 35 to 44 years, hypertension was the strongest independent predictor for HF. Diabetes and myocardial infarction emerged as predictors for HF among patients aged 35 years and older. CONCLUSIONS: The overall rate of HF hospitalization declined during the period surveyed, but the persistent disproportionate involvement of blacks with evidence of worsening among younger black men, requires close attention.

Assessment of commonly available education materials in heart failure clinics.

BACKGROUND: Health literacy (HL) is an established independent predictor of cardiovascular outcomes. Approximately 90 million Americans have limited HL and read at the fifth grade level or lower. Therefore, we sought to determine the suitability and readability level of common cardiovascular patient education materials (PEM) related to heart failure and heart-healthy lifestyle. METHODS AND RESULTS: The suitability and readability of written PEMs were assessed using the suitability assessment of materials (SAM) and Fry readability formula. The SAM criteria are composed of the following categories: message content, text appearance, visuals, and layout and design. We obtained a convenience sample of 18 English-written cardiovascular PEMs freely available from major health organizations. Two reviewers independently appraised the PEMs. Final suitability scores ranged from 12% to 87%. Readability levels ranged between 3rd and 15th grade level; the average readability level was 8th grade. Ninety-four percent of the PEMs were rated either superior or adequate on text appearance, but 50% or more of the PEMs were rated inadequate on each of the other categories of the SAM criteria. Only 2 (11%) PEMs had the optimum suitability score of 70% or higher and 5th grade or lower readability level suitable for populations with limited HL. CONCLUSIONS: Commonly available cardiovascular PEMs used by some major healthcare institutions are not suitable for the average American patient. The true prevalence of suboptimal PEMs needs to be determined because it potentially negatively impacts optimal healthcare delivery and outcomes.

Advancing the Science of Healthcare Service Delivery: The NHLBI Corporate Healthcare Leaders' Panel.

There is a growing gap between available science and evidence and the ability of service providers to deliver high-quality care in a cost-effective way to the entire population. We believe that the chasm between knowledge and action is due to a lack of concerted effort among all organizations that deliver health care services across the life span of patients. Broad participation is needed and necessitates a far more explicit and concerted public-private partnership focused on large-scale transformation. In this context, the National Heart, Lung, and Blood Institute convened a panel made up of leaders of corporate health care entities, including academic health centers, and government agency representatives to inform contemporary strategic partnerships with health care companies. This article provides insights from the meeting on how to execute a transformative innovation research agenda that will foster improvements in health care service delivery by leveraging the translation of biomedical research evidence in real-world settings.

CT-based attenuation correction versus prone imaging to decrease equivocal interpretations of rest/stress Tc-99m tetrofosmin SPECT MPI.

BACKGROUND: The purpose of this study was to compare stress supine single photon emission computed tomography (SPECT) imaging with attenuation correction (AC) via computed tomography-based attenuation maps with stress prone SPECT imaging with regard to the rate of equivocal interpretation of rest/stress myocardial perfusion imaging. METHODS AND RESULTS: Interpretations for 324 consecutive patients referred for rest/stress myocardial perfusion imaging were performed by use of the following sets of poststress SPECT images: supine with no AC (NC), supine NC/AC, supine NC/prone, and all images. The number of equivocal studies decreased with additional imaging: supine NC, 40%; supine NC/prone, 18%; supine NC/AC, 11%; and all images, 8%. The supine NC/AC sets of images reduced the number of defects to a greater extent than the supine NC/prone images for all patients (P = .01), men (P = .002), and women (P = .425). For the inferior (but not the anterior) wall, the percent decrease in defects with supine NC/AC images was lower as compared with supine NC/prone images. CONCLUSION: Interpretation with all images resulted in the fewest equivocal studies. The supine NC/AC images reduced the number of equivocal studies to a greater extent than the supine NC/prone images. AC and prone imaging were more helpful in men than women and were more helpful to resolve inferior than anterior wall defects. Adding prone imaging to supine imaging without and with AC does not significantly alter the number of equivocal interpretations.

Peripheral artery disease: epidemiology and global perspectives.

Global populations are undergoing a major epidemiological transition in which the burden of atherosclerotic cardiovascular diseases is shifting rapidly from high-income to low-income and middle-income countries (LMICs). Peripheral artery disease (PAD) is no exception, so that greater focus is now required on the prevention and management of this disease in less-advantaged countries. In this Review, we examine the epidemiology of PAD and, where feasible, take a global perspective. However, the dearth of publications in LMICs means an unavoidable over-reliance on studies in high-income countries. Research to date suggests that PAD might affect a greater proportion of women than men in LMICs. Although factors such as poverty, industrialization, and infection might conceivably influence the development of PAD in such settings, the ageing of the population and increase in traditional cardiovascular risk factors, such as smoking, diabetes mellitus, and hypertension, are likely to be the main driving forces.

Perspectives from NHLBI Global Health Think Tank Meeting for Late Stage (T4) Translation Research.

Almost three-quarters (74%) of all the noncommunicable disease burden is found within low- and middle-income countries. In September 2014, the National Heart, Lung, and Blood Institute held a Global Health Think Tank meeting to obtain expert advice and recommendations for addressing compelling scientific questions for late stage (T4) research-research that studies implementation strategies for proven effective interventions-to inform and guide the National Heart, Lung, and Blood Institute's global health research and training efforts. Major themes emerged in two broad categories: 1) developing research capacity; and 2) efficiently defining compelling scientific questions within the local context. Compelling scientific questions included how to deliver inexpensive, scalable, and sustainable interventions using alternative health delivery models that leverage existing human capital, technologies and therapeutics, and entrepreneurial strategies. These broad themes provide perspectives that inform an overarching strategy needed to reduce the heart, lung, blood, and sleep disorders disease burden and global health disparities.

Reducing Health Inequities in the U.S.: Recommendations From the NHLBI's Health Inequities Think Tank Meeting.

The National, Heart, Lung, and Blood Institute convened a Think Tank meeting to obtain insight and recommendations regarding the objectives and design of the next generation of research aimed at reducing health inequities in the United States. The panel recommended several specific actions, including: 1) embrace broad and inclusive research themes; 2) develop research platforms that optimize the ability to conduct informative and innovative research, and promote systems science approaches; 3) develop networks of collaborators and stakeholders, and launch transformative studies that can serve as benchmarks; 4) optimize the use of new data sources, platforms, and natural experiments; and 5) develop unique transdisciplinary training programs to build research capacity. Confronting health inequities will require engaging multiple disciplines and sectors (including communities), using systems science, and intervening through combinations of individual, family, provider, health system, and community-targeted approaches. Details of the panel's remarks and recommendations are provided in this report.

Endothelial dysfunction: a unifying hypothesis for the burden of cardiovascular diseases in sub-Saharan Africa.

It is well established that the leading causes of death and disability worldwide are cardiovascular diseases (CVD), chief among which is ischaemic heart disease. However, it is also recognised that ischaemic heart disease frequently coexists with other vascular conditions, such as cerebrovascular, renovascular and peripheral vascular disease, thus raising the notion of a common underlying pathobiology, albeit with differing manifestations, dictated by the implicated vascular bed. The understanding that common metabolic and behavioural risk factors as well as social determinants and drivers are convergent in the development of CVD evokes the idea that the dysfunction of a common bio-molecular platform is central to the occurrence of these diseases. The state of endothelial activation, otherwise known as endothelial dysfunction, occurs when reactive oxygen signalling predominates due to an uncoupled state of endothelial nitric oxide synthase (eNOS). This can be a physiological response to stimulation of the innate immune system or a pathophysiological response triggered by cardiovascular disease risk factors. The conventional wisdom is that the endothelium plays an important role in the initiation, progression and development of CVD and other non-communicable diseases. Consequently, the endothelium has remarkable relevance in clinical and public health practice as well as in health education, health promotion, and disease- and risk-factor prevention strategies. It also presents a plausible unifying hypothesis for the burden of CVD seen globally and in sub-Saharan Africa. Importantly, the heterogeneity in individual responses to metabolic, behavioural, and social drivers of CVD may stem from a complex interplay of these drivers with genomic, epigenetic and environmental factors that underpin eNOS uncoupling. Therefore, further biomedical research into the underlying genetic and other mechanisms of eNOS uncoupling may enlighten and shape strategies for addressing the burden of CVD in sub-Saharan Africa and other regions of the world.

Mortality from cardiovascular diseases in sub-Saharan Africa, 1990-2013: a systematic analysis of data from the Global Burden of Disease Study 2013.

BACKGROUND: Cardiovascular disease (CVD) has been the leading cause of death in developed countries for most of the last century. Most CVD deaths, however, occur in low- and middle-income, developing countries (LMICs) and there is great concern that CVD mortality and burden are rapidly increasing in LMICs as a result of population growth, ageing and health transitions. In sub-Saharan Africa (SSA), where all countries are part of the LMICs, the pattern, magnitude and trends in CVD deaths remain incompletely understood, which limits formulation of data-driven regional and national health policies. OBJECTIVE: The aim was to estimate the number of deaths, death rates, and their trends for CVD causes of death in SSA, by age and gender for 1990 and 2013. METHODS: Age- and gender-specific mortality rates for CVD were estimated using the Global Burden of Disease (GBD) 2010 methods with some refinements made by the GBD 2013 study to improve accuracy. Cause of death was estimated as in the GBD 2010 study and updated with a verbal autopsy literature review and cause of death ensemble modelling (CODEm) estimation for causes with sufficient information. For all quantities reported, 95% uncertainty intervals (UIs) were also computed. RESULTS: In 2013, CVD caused nearly one million deaths in SSA, constituting 38.3% of non-communicable disease deaths and 11.3% of deaths from all causes in that region. SSA contributed 5.5% of global CVD deaths. There were more deaths in women (512,269) than in men (445,445) and more deaths from stroke (409,840) than ischaemic heart disease (258,939). Compared to 1990, the number of CVD deaths in SSA increased 81% in 2013. Deaths for all component CVDs also increased, ranging from a 7% increase in incidence of rheumatic heart disease to a 196% increase in atrial fibrillation. The age-standardised mortality rate (per 100,000) in 1990 was 327.6 (CI: 306.2-351.7) and 330.2 (CI: 312.9-360.0) in 2013, representing only a 1% increase in more than two decades. CONCLUSIONS: In SSA, CVDs are neither epidemic nor among the leading causes of death. However, a significant increase in the number of deaths from CVDs has occurred since 1990, largely as a result of population growth, ageing and epidemiological transition. Contrary to what has been observed in other world regions, the age-adjusted mortality rate for CVD has not declined. Another important difference in CVD deaths in SSA is the predominance of stroke as the leading cause of death. Attention to aggressive efforts in cardiovascular health promotion and CVD prevention, treatment and control in both men and women are warranted. Additionally, investments to improve directly enumerated epidemiological data for refining the quantitation of risk exposures, death certification and burden of disease assessment will be crucial.

Smoking, sex, risk factors and abdominal aortic aneurysms: a prospective study of 18†782 persons aged above 65 years in the Southern Community Cohort Study.

BACKGROUND: Abdominal aortic aneurysm (AAA) is a leading cause of death in the USA. We evaluated the incidence and predictors of AAA in a prospectively followed cohort. METHODS: We calculated age-adjusted AAA incidence rates (IR) among 18 782 participants aged ≥65 years in the Southern Community Cohort Study who received Medicare coverage from 1999-2012, and assessed predictors of AAA using multivariable Cox proportional hazards models, overall and stratified by sex, adjusting for demographic, lifestyle, socioeconomic, medical and other factors. HRs and 95% CIs were calculated for AAA in relation to factors ascertained at enrolment. RESULTS: Over a median follow-up of 4.94 years, 281 cases were identified. Annual IR was 153/100,000, 401, 354 and 174 among blacks, whites, men and women, respectively. AAA risk was lower among women (HR 0.48, 95% CI 0.36 to 0.65) and blacks (HR 0.51, 95% CI 0.37 to 0.69). Smoking was the strongest risk factor (former: HR 1.91, 95% CI 1.27 to 2.87; current: HR 5.55, 95% CI 3.67 to 8.40), and pronounced in women (former: HR 3.4, 95% CI 1.83 to 6.31; current: HR 9.17, 95% CI 4.95 to 17). A history of hypertension (HR 1.44, 95% CI 1.04 to 2.01) and myocardial infarction or coronary artery bypass surgery (HR 1.9, 95% CI 1.37 to 2.63) was negatively associated, whereas a body mass index ≥25 kg/m(2) (HR 0.72; 95% CI 0.53 to 0.98) was protective. College education (HR 0.6, 95% CI 0.37 to 0.97) and black race (HR 0.44, 95% CI 0.28 to 0.67) were protective among men. CONCLUSIONS: Smoking is a major risk factor for incident AAA, with a strong and similar association between men and women. Further studies are needed to evaluate benefits of ultrasound screening for AAA among women smokers.

Factors associated with the prevalence of hypertension in the southeastern United States: insights from 69,211 blacks and whites in the Southern Community Cohort Study.

BACKGROUND: Lifestyle and socioeconomic status have been implicated in the prevalence of hypertension; thus, we evaluated factors associated with hypertension in a cohort of blacks and whites with similar socioeconomic status characteristics. METHODS AND RESULTS: We evaluated the prevalence and factors associated with self-reported hypertension (SR-HTN) and ascertained hypertension (A-HTN) among 69,211 participants in the Southern Community Cohort Study. Multivariable logistic regression models were used to estimate the odds ratios (ORs) and 95% confidence intervals (CIs) for factors associated with hypertension. The prevalence of SR-HTN was 57% overall. Body mass index was associated with SR-HTN in all race-sex groups, with the OR rising to 4.03 (95% CI, 3.74-4.33) for morbidly obese participants (body mass index, >40 kg/m(2)). Blacks were more likely to have SR-HTN than whites (OR, 1.84; 95% CI, 1.75-1.93), and the association with black race was more pronounced among women (OR, 2.08; 95% CI, 1.95-2.21) than men (OR, 1.47; 95% CI, 1.36-1.60). Similar findings were noted in the analysis of A-HTN. Among those with SR-HTN and A-HTN who reported use of an antihypertensive agent, 94% were on at least one of the major classes of antihypertensive agents, but only 44% were on ≥2 classes and only 29% were on a diuretic. The odds of both uncontrolled hypertension (SR-HTN and A-HTN) and unreported hypertension (no SR-HTN and A-HTN) were twice as high among blacks as whites (OR, 2.13; 95% CI, 1.68-2.69; and OR, 1.99; 95% CI, 1.59-2.48, respectively). CONCLUSIONS: Despite socioeconomic status similarities, we observed suboptimal use of antihypertensives in this cohort and racial differences in the prevalence of uncontrolled and unreported hypertension, which merit further investigation.

Global and regional burden of death and disability from peripheral artery disease: 21 world regions, 1990 to 2010.

A comprehensive and systematic assessment of disability and mortality due to lower extremity peripheral artery disease (PAD) is lacking. Therefore, we estimated PAD deaths, disability-adjusted life years (DALYs), and years of life lost in 21 regions worldwide for 1990 and 2010. We used the GBD (Global Burden of Diseases 2010) study causes of death database, and the cause of death ensemble modeling approach to assess levels and trends of PAD deaths and years of life lost over time, by age, sex, and region. Assessment of DALYs employed estimates of PAD prevalence from systematic reviews of epidemiologic data using a Bayesian meta-regression method. In 1990, the age-specific PAD death rate per 100,000 population ranged from 0.05 (95% confidence interval [CI]: 0.03 to 0.09) among those 40 to 44 years old to 16.63 (95% CI: 10.47 to 25.31) among the 80+ years group. In 2010, the corresponding estimates were 0.07 (95% CI: 0.04 to 0.13) and 28.71 (95% CI: 18.3 to 43.06). Death rates increased consistently with age in 1990 and 2010, and the rates in 2010 were higher than they were in 1990 in all age categories. The largest relative change in median death rate of +6.03 per 100,000 (95% CI: 1.50 to 11.85) was noted in the Asia Pacific-High Income region and was largely driven by higher rates in women: +17.36 (95% CI: 1.79 to 32.01) versus +1.25 (95% CI: 0.13 to 2.39) in men. The overall relative change in median DALYs was larger in developing nations than in developed nations: 1.15 (95% CI: 0.80 to 1.66) versus 0.77 (95% CI: 0.55 to 1.08). Of note, the overall relative change in median DALYs was higher among both men and women in developing versus developed countries: men: 1.18 (95% CI: 0.82 to 1.65) versus 0.51 (95% CI: 0.30 to 0.81), and women: 1.11 (95% CI: 0.58 to 2.02) versus 1 (95% CI: 0.67 to 1.47). Within developed nations, the overall relative change in median DALY rates was larger in women than in men: +1.00 (95% CI: 0.67 to 1.47) versus +0.51 (95% CI: 0.3 to 0.81). Similarly, the overall relative change in median years of life lost rate in developed countries was larger in women than in men: +1.64 (95% CI: 1.17 to 2.34) versus +0.53 (95% CI: 0.24 to 0.94). The relative increases in median years lived with nonfatal disease disability (YLD) rates in men and women were larger in developing versus developed nations: men: 0.87 (95% CI: 0.59 to 1.2) versus 0.49 (95% CI: 0.29 to 0.73), and women: 0.75 (95% CI: 0.46 to 1.09) versus 0.49 (95% CI: 0.29 to 0.73). Disability and mortality associated with PAD has increased over the last 20 years, and this increase in burden has been greater among women than among men. In addition, the burden of PAD is no longer confined to the elderly population, but now involves young adults. Furthermore, the relative increase in PAD burden in developing regions of the world is striking and exceeds the increases in developed nations.

Global and regional burden of aortic dissection and aneurysms: mortality trends in 21 world regions, 1990 to 2010.

A comprehensive and systematic assessment of the global burden of aortic aneurysms (AA) has been lacking. Therefore, we estimated AA regional deaths and years of life lost (YLL) in 21 regions worldwide for 1990 and 2010. We used the GBD (Global Burden of Disease) 2010 study causes of death database and the cause of death ensemble modeling approach to assess levels and trends of AA deaths by age, sex, and GBD region. The global AA death rate per 100,000 population was 2.49 (95% CI: 1.78 to 3.27) in 1990 and 2.78 (95% CI: 2.04 to 3.62) in 2010. In 1990 and 2010, the highest mean death rates were in Australasia and Western Europe: 8.82 (95% CI: 6.96 to 10.79) and 7.69 (95% CI: 6.11 to 9.57) in 1990 and 8.38 (95% CI: 6.48 to 10.86) and 7.68 (95% CI: 6.13 to 9.54) in 2010. YLL rates by GBD region mirrored the mortality rate pattern. Overall, men had higher AA death rates than women: 2.86 (95% CI: 1.90 to 4.22) versus 2.12 (95% CI: 1.33 to 3.00) in 1990 and 3.40 (95% CI: 2.26 to 5.01) versus 2.15 (95% CI: 1.44 to 2.89) in 2010. The relative change in median death rate was +0.22 (95% CI: 0.10 to 0.33) in developed nations versus +0.71 (95% CI: 0.28 to 1.40) in developing nations. The smallest relative changes in median death rate were noted in North America high income, Central Europe, Western Europe, and Australasia, with estimates of +0.07 (95% CI: -0.26 to 0.37), +0.08 (95% CI: -0.02 to 0.23), +0.09 (95% CI: -0.02 to 0.21), and +0.22 (95% CI: -0.08 to 0.46), respectively. The largest increases were in Asia Pacific high income, Southeast Asia, Latin America tropical, Oceania, South Asia, and Central Sub-Saharan Africa. Women rather than men drove the increase in the Asia Pacific high-income region: the relative change in median rates was +2.92 (95% CI: 0.6 to 4.35) versus +1.05 (95% CI: 0.61 to 2.42). In contrast to high-income regions, the observed pattern in developing regions suggests increasing AA burden, which portends future health system challenges in these regions.
