Acute exposure to BPA can inhibit voltage-gated calcium channels, impairing cardiomyocyte calcium handling and affecting heart contraction.

“BPA doesn't just mess with our hormones it actually directly affects our heart's ability to function properly one of the key mechanisms here is how BPA disrupts calcium signaling in heart cells so calcium is essential for the electrical activity of the heart it helps regulate things like heart rate contractile function and even how blood vessels dilate Studies have shown that acute exposure to BPA can inhibit voltage gated calcium channels which impaires how cardiomyocytes these are the cells in our heart handle calcium and this disruption can affect how the heart contracts and it can trigger abnormal activities in the heart muscle”
