Pumped blood to various parts of the body (4. 7l/min) Ruptured or obstructed blood vessels can mean oxygen deprivation to body parts, death of body part (necrosis). Heart also requires a blood supply, so if coronary arteries are blocked, heart tissue can die (myocardial infarction). Because arteries that supply heart with blood=coronary arteries, any problem with them is called coronary heart disease (chd) or coronary artery disease. Heart disease can be hereditary, caused by rheumatic fever. Most prevalent form of heart disease is chd: a condition in which the heart is supplied with insufficient blood due to clogging of coronary arteries.
