Lead killed roughly 1.48 million people from cardiovascular disease in a single year. That's not ancient history. That's 2021.
The Global Numbers
A 2026 analysis in Front Public Health used Global Burden of Disease 2021 data to quantify how many heart deaths lead exposure causes worldwide. The toll: 1.48 million deaths and 30 million disability-adjusted life years (DALYs) lost.
Men were hit harder than women. And the burden is shifting. Wealthy countries are getting better at reducing lead exposure. Poor countries are getting worse.
The Gap Is Getting Wider
From 1990 to 2021, age-standardized death rates dropped overall. But in low-income countries, the absolute number of deaths and DALYs kept climbing. Population growth accounted for 96% of the increase in deaths.
The inequality between rich and poor nations widened significantly over three decades. Lead is becoming a disease of poverty.
Lead Is Still Everywhere
Lead comes from old paint, contaminated soil, water pipes, some imported goods, and industrial emissions. Even at low levels, it damages blood vessels and raises blood pressure. Over years, that leads to heart attacks and strokes.
What You Can Do
Test your water for lead. If your home was built before 1978, test for lead paint. Avoid imported ceramics and toys that may contain lead. And switch to non-toxic home essentials to remove sources of lead from your daily life.
