Most know severe infection can cause heart damage but so can toxins that are found in our food especially glyphosate. I believe it is what is contributing to so many dying very young from heart failure. We know glyphosate is found in high levels in our food supply and many of our sources of water has high levels of glyphosate.
Glyphosate causes high hydrogen peroxide levels. This damages the lungs and heart.

Hydrogen peroxide is involved in normal function of the heart.

Excess H2O2 can impair proper function of the heart.

The lungs and heart interact this can cause one or the other to fail.

Some infections can increase hydrogen peroxide level. The body also increases H2O2 to fight infection.

This is why glyphosate and glufonisate are toxic to the heart.
