Candida’s involvement in heart conditions typically includes endocarditis, peritonitis, pericarditis, and myocarditis, but can also include lesser heart problems and manifestations. The primary effect produced by candida on heart tissue is through increased levels of inflammation, as seen in the “-itis” designation of the various conditions mentioned, but may also involve degeneration of tissues due to any of the enzymes produced by fungal candida (SAPs, lipases, phospholipases, etc). While suppression of immune function has traditionally been thought to be a prerequisite, newer research continually shows that not to be the case.
