Hypertension ‘Kills More People Around the World than Anything Else’
“Hypertension affects nearly one in three adults and kills more people around the world than anything else. It is both too common and too often poorly controlled.”
So said Tom Frieden, MD, MPH, director of the U.S. Centers for Disease Control and Prevention (CDC), during a panel discussion at the annual meeting of the American Society of Hypertension (ASH) this past weekend. The panel was convened by ASH, the American Heart Association and the CDC to launch a project supporting improved control of hypertension worldwide. According to the panel an estimated 970 million people have hypertension worldwide, and the disease is responsible for more than nine million deaths, as hypertension can lead to heart disease and stroke.
Data from the groups finds that rates of hypertension have increased in both developed and developing nations, due in part to an aging population and lifestyles that include high salt diets and low physical activity.
For the developing world, the CDC; the Pan American Health Organization; and other regional and global stakeholders are identifying both cost effective medicines and inexpensive delivery strategies for the drugs to help patients afford and receive them.
In the United States, the Affordable Care Act is expected to increase the number of people on hypertension medications, but despite the availability of coverage for hypertension diagnosis and treatment there remains concern over disparities. A study of more than 16,000 members of the Hispanic community published in the American Journal of Hypertension earlier this year found that while the prevalence of hypertension among Hispanics is nearly equal to that of non-Hispanic whites, diagnosis of the disease is much lower, as is general awareness of its symptoms and treatment options.
"Given the relative ease of identifying hypertension and the availability of low-cost medications, enabling better access to diagnostic and treatment services should be prioritized to reduce the burden of cardiovascular disease on Hispanic populations,” said Paul Sorlie, MD, the lead author of the study and an epidemiologist with the National Heart, Lung and Blood Institute. “This study gives us the information needed to support the development of policies that can improve this access and, subsequently, the overall health of countless US citizens.”
