Sex parity ratios (SPRs) for the global burden of ischemic heart disease (IHD) from 1990 to 2021. The figure illustrates SPRs for mortality, disability-adjusted life years (DALYs), incidence, and prevalence across various age groups. SPRs for IHD prevalence and incidence increased across all age groups, while SPRs for IHD-related mortality and DALYs decreased, indicating diminishing sex disparity. The most pronounced changes in mortality and DALY SPRs occurred in adults over 70 years old
