Can PFAS exposure weaken your heart muscle cells?
Some Concern
What's actually in it
PFAS from nonstick cookware, food packaging, and contaminated water build up in your blood and reach every organ, including your heart. Heart muscle cells (cardiomyocytes) need healthy mitochondria and protein structure to pump blood effectively. PFAS can interfere with these critical functions.
What the research says
A 2026 study in Chem Res Toxicol exposed human heart muscle cells to PFAS and measured the effects on their structure and function. The researchers found that PFAS caused changes in proteins related to the heart's structural framework, energy metabolism, and mitochondrial function.
Damaged mitochondria mean heart cells can't produce enough energy to beat properly. Disrupted structural proteins weaken the heart muscle itself. These effects could contribute to heart failure, arrhythmias, and cardiovascular disease over time.
Protect your heart by reducing PFAS exposure. Use cast iron or stainless steel cookware, filter your drinking water, and avoid stain-resistant and water-resistant chemical treatments on home goods.
