Histopathology of cardiac muscle

Cardiac muscle explanatory video

Coronary arteries are blocked in cases of coronary thrombosis leading to blockage of blood supply to cardiac muscles and causing an infarct called myocardial infarct.

Coronary artery thrombosis

Other conditions of the heart include

*Carcinoid heart disease


  • Dilated cardiomyopathy
  • Hypertrophic cardiomyopathy
  • Restrictive cardiomyopathy
  • Arrythmogenic right ventricular cardiomyopathy
  • Myocarditis

*Congenital heart diseases

*Heart failure

*Ischemic heart disease

*Hypertensive heart disease

  • Left sided hypertension
  • Right sided hypertension (Cor pulmonale)

*Pericardial disease

*Tumors of the Heart

*Valvular heart disease
