🌿 Overview

Cardiomyopathy means heart muscle disease — the myocardium becomes damaged, leading to an enlarged, weakened heart that cannot pump blood efficiently. The World Health Organization recognizes it as a selenium deficiency disease.

Cardiomyopathy refers to a group of diseases of the heart muscle (myocardium) that impair the heart's ability to pump blood. The heart may enlarge, its chambers may dilate, or the muscle may become rigid. Symptoms often develop gradually: fatigue, shortness of breath on exertion, palpitations, and swollen ankles. The WHO recognizes that cardiomyopathy is associated with selenium deficiency.

Common signs

  • Fatigue
  • Shortness of breath on exertion (in later stages even at rest)
  • Palpitations and irregular heartbeat
  • Swelling of the ankles and feet
  • Often: no symptoms in early stages
