From 1990 to 2021, the age-standardized incidence rate increased by a slight annual change of 0.4%, while the age-standardized mortality and DALY rates declined by 1.04% and 1.02% annually, respectively. Regional analysis revealed the highest IHD burden in North Africa and the Middle East, while Oceania reported the highest mortality-to-incidence ratio. While the age-standardized mortality and DALYs rates of IHD have shown a declining trend in low- and middle-SDI regions, the absolute numbers of deaths and DALYs have risen substantially. Attributable risks, including poor diet, tobacco use, high body mass index, and high blood pressure, were major contributors to IHD-related deaths and DALYs. Notably, the proportion of IHD attributable to high BMI and high blood pressure has increased, particularly in higher-SDI regions.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>The burden of IHD among WCBA is rising globally, with significant regional disparities and increasing attributable risks, particularly in low- and middle-SDI regions.
