This report summarizes the findings of the GBD 2010 (Global Burden of Diseases, Injuries, and Risk Factors) study for hemorrhagic stroke (HS). Multiple databases were searched for relevant studies published between 1990 and 2010. The GBD 2010 study provided standardized estimates of the incidence, mortality, mortality-to-incidence ratios (MIR), and disability-adjusted life years (DALY) lost for HS (including intracerebral hemorrhage and subarachnoid hemorrhage) by age, sex, and income level (high-income countries [HIC]; low- and middle-income countries [LMIC]) for 21 GBD 2010 regions in 1990, 2005, and 2010. ⋯ The lowest incidence and mortality rates in 2010 were in High Income North America, Australasia, and Western Europe, whereas the highest rates were in Central Asia, Southeast Asia, and sub-Saharan Africa. These results suggest that reducing the burden of HS is a priority particularly in LMIC. The GBD 2010 findings may be a useful resource for planning strategies to reduce the global burden of HS.

The global burden of abdominal aortic aneurysm (AAA) has not been studied previously. Such information is important given the emergence of cardiovascular diseases in developing countries. We conducted a systematic literature review and estimated the global and regional incidence and prevalence of AAA in 21 world regions by age and sex. ⋯ Regional prevalence increased in Oceania, tropical Latin America, Asia Pacific high income, Southern Sub-Saharan Africa (SSA), Central SSA, South Asia, Western SSA, and Central Asia. AAA global prevalence and incidence rates have decreased over the last 20 years. However, rising rates in some regions highlight the need for policies to enhance global disease surveillance and prevention.

This study sought to summarize the findings of the GBD 2010 (Global Burden of Diseases, Injuries, and Risk Factors) study for ischemic stroke (IS) and to report the impact of tobacco smoking on IS burden in specific countries. The GBD 2010 searched multiple databases to identify relevant studies published between 1990 and 2010. The GBD 2010 analytical tools were used to calculate region-specific IS incidence, mortality, mortality-to-incidence ratio, and disability-adjusted life years (DALY) lost, including 95% uncertainty intervals (UI). ⋯ Tobacco consumption is an important modifiable risk factor for IS, and in both 1990 and 2010, the top ranked countries for IS deaths that could be attributed to tobacco consumption were China, Russia, and India. Tobacco control policies that target both smoking initiation and smoking cessation can play an important role in the prevention of IS. In China, Russia, and India, even modest reductions in the number of current smokers could see millions of lives saved due to prevention of IS alone.

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. ⋯ 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.

Ischemic heart disease (IHD) was the leading cause of disease burden worldwide in 2010. The majority of IHD burden affected middle-income regions. We hypothesized IHD burden may vary among countries, even within the same broad geographic region. ⋯ The majority of IHD burden in 2010 affected middle-income regions, where younger adults were more likely to develop IHD in regions such as South Asia and North Africa/Middle East. However, IHD burden varied substantially by country within regions, especially among middle-income countries. A global or regional approach to IHD prevention will not be sufficient; research and policy should focus on the highest burden countries within regions.
