Global, Regional, and National Burden of Cardiovascular Diseases for 10 Causes, 1990 to 2015
Background The burden of cardiovascular diseases ( CVDs ) remains unclear in many regions of the world . Objectives The GBD ( Global Burden of Disease ) 2015 study integrated data on disease incidence , prevalence , and mortality to produce consistent , up-to- date estimates for cardiovascular burden . Methods CVD mortality was estimated from vital registration and verbal autopsy data . CVD prevalence was estimated using modeling software and data from health surveys , prospect i ve cohorts , health system administrative data , and registries . Years lived with disability ( YLD ) were estimated by multiplying prevalence by disability weights . Years of life lost ( YLL ) were estimated by multiplying age-specific CVD deaths by a reference life expectancy . A sociodemographic index ( SDI ) was created for each location based on income per capita , educational attainment , and fertility . Results In 2015 , there were an estimated 422.7 million cases of CVD ( 95 % uncertainty interval : 415.53 to 427.87 million cases ) and 17.92 million CVD deaths ( 95 % uncertainty interval : 17.59 to 18.28 million CVD deaths ) . Declines in the age-st and ardized CVD death rate occurred between 1990 and 2015 in all high-income and some middle-income countries . Ischemic heart disease was the leading cause of CVD health lost globally , as well as in each world region , followed by stroke . As SDI increased beyond 0.25 , the highest CVD mortality shifted from women to men . CVD mortality decreased sharply for both sexes in countries with an SDI > 0.75 . Conclusions CVDs remain a major cause of health loss for all regions of the world . Sociodemographic change over the past 25 years has been associated with dramatic declines in CVD in regions with very high SDI , but only a gradual decrease or no change in most regions . Future up date s of the GBD study can be used to guide policymakers who are focused on reducing the overall burden of noncommunicable disease and achieving specific global health targets for CVD
