Heavy drinking can also cause cardiomyopathy , a potentially deadly condition in which the heart muscle weakens and eventually fails, as well as heart rhythm abnormalities such as atrial and ventricular fibrillation. Atrial fibrillation , in which the heart's upper chambers (atria) twitch chaotically rather than constrict rhythmically, can cause blood clots that can trigger a stroke . Ventricular fibrillation causes chaotic twitching in the heart's main pumping chambers (ventricles). It causes rapid loss of consciousness and, in the absence of immediate treatment, sudden death.
This document provides background and contextual information about per- and poly-fluoroalkyl substances (PFAS), which were previously known as "perfluorinated chemicals", or "PFCs", and guidance for state and territory public health units for use in assessing any public health risks where these chemicals have been released into the environment. The enHealth Guidance Statements on Per- and Poly-fluoroalkyl Substances (the enHealth Guidance Statements) also provide guidance on the potential health impacts from exposure to three types of PFAS - perfluorooctane sulfonate (PFOS), perfluorohexane sulfonate (PFHxS) and perfluorooctanoic acid (PFOA); the major human exposure pathways; the development of human health reference values for PFOS, PFOA and PFHxS; breast feeding and pregnancy; and blood tests.
