The Claim
High systolic blood pressure is the leading risk factor for ischemic heart disease mortality in adults aged 55 and above, accounting for 53.74% of global ischemic heart disease-related deaths, with higher attributable fractions in low- and middle-SDI regions.
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.
In adults aged 55 and older, high systolic blood pressure causes more deaths from ischemic heart disease than any other risk factor, responsible for over half of all such deaths globally, with the highest proportions in low- and middle-income regions.
See the scientific wording
High systolic blood pressure is the leading risk factor for ischemic heart disease mortality in adults aged 55 and above, accounting for 53.74% of global IHD-related deaths, with higher attributable fractions in low- and middle-SDI regions.
High blood pressure constantly pushes too hard against artery walls, causing them to thicken and stiffen. This damage lets fatty deposits build up inside the arteries that supply the heart, narrowing them over time. When these arteries become blocked, the heart muscle doesn't get enough oxygen, leading to tissue death and fatal heart attacks.
What the research says
1 studyThis study found that high blood pressure caused more than half of all heart disease deaths in people over 55 worldwide, especially in poorer countries — just like the claim says.
