Global epidemiology of valvular heart disease

Abstract

Valvular heart disease (VHD) is a major contributor to loss of physical function, quality of life and longevity. The epidemiology of VHD varies substantially around the world, with a predominance of functional and degenerative disease in high-income countries, and a predominance of rheumatic heart disease in low-income and middle-income countries. Reflecting this distribution, rheumatic heart disease remains by far the most common manifestation of VHD worldwide and affects approximately 41 million people. By contrast, the prevalence of calcific aortic stenosis and degenerative mitral valve disease is 9 and 24 million people, respectively. Despite a reduction in global mortality related to rheumatic heart disease since 1900, the death rate has remained fairly static since 2000. Meanwhile, deaths from calcific aortic stenosis have continued to rise in the past 20 years. Epidemiological data on other important acquired and congenital forms of VHD are limited. An ageing population and advances in therapies make an examination of the changing global epidemiology of VHD crucial for advances in clinical practice and formulation of health policy. In this Review, we discuss the global burden of VHD, geographical variation in the presentation and clinical management, and temporal trends in disease burden.
