Global, regional, and national burden of hypertensive heart disease among older adults in 204 countries and territories between 1990 and 2019: a trend analysis.

BACKGROUND

Hypertensive heart disease (HHD) poses a public health challenge, but data on its burden and trends among older adults are scarce. This study aimed to identify trends in the burden of HHD among older adults between 1990 and 2019 at the global, regional, and national levels.

METHODS

Using the Global Burden of Diseases study 2019 data, we assessed HHD prevalence, death, and disability-adjusted life-year (DALY) rates for individuals aged 60-89 years at the global, regional, and national levels and estimated their average annual percentage changes (AAPCs) between 1990 and 2019 using joinpoint regression analysis.

RESULTS

In 2019, there were 14.35 million HHD prevalent cases, 0.85 million deaths, and 14.56 million DALYs in older adults. Between 1990 and 2019, the prevalence of HHD increased globally {AAPC, 0.38 (95% confidence interval [CI], 0.36, 0.41)} with decreases observed in mortality (AAPC, -0.83 [95% CI, -0.99, -0.66]) and the DALY rate (AAPC, -1.03 [95% CI, -1.19, -0.87]). This overall global trend pattern was essentially maintained for sex, age group, and sociodemographic index (SDI) quintile except for non-significant changes in the prevalence of HHD in those aged 70-74 years and in the middle SDI quintile. Notably, males had a higher HHD prevalence rate. However, HHD-related mortality and the DALY rate were higher in females. The middle SDI quintile experienced the largest decreases in mortality and the DALY rate, with a non-significant decline in prevalence between 1990 and 2019. There were significant discrepancies in the HHD burden and its trends across regions and countries.

CONCLUSIONS

In the past three decades, there has been an overall increasing trend in the prevalence of HHD among older adults worldwide despite decreasing trends in mortality and the DALY rate. Better management of hypertension, and prevention and control of HHD are needed in older adults.
