The Claim
From 1990 to 2021, age-standardized ischemic heart disease mortality decreased by 49% in high Socio-Demographic Index (SDI) regions, with an average annual decline of 3.43%, representing the steepest global reduction in mortality during this period.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Between 1990 and 2021, high-income regions saw a 49% drop in deaths from ischemic heart disease, with an average yearly decrease of 3.43%, the largest decline observed anywhere in the world.
See the scientific wording
From 1990 to 2021, age-standardized ischemic heart disease mortality declined by 49% in high Socio-Demographic Index (SDI) regions, with an average annual decline of 3.43%, the steepest reduction observed globally, indicating that higher-income regions achieved the most substantial and earliest improvements in cardiovascular outcomes.
Better access to medications and healthy lifestyles lowers blood pressure, cholesterol, and blood sugar, which slows the buildup of fatty deposits in artery walls and prevents those deposits from cracking and blocking blood flow to the heart.
What the research says
1 studyIn rich countries, heart disease deaths dropped by almost half between 1990 and 2021 — faster than anywhere else in the world. The study proves this happened and that poorer countries didn’t see the same level of improvement.
