It is the most common cause of death in most western countries.p Ischaemia means a reduced blood supply. The coronary arteries supply blood to the heart muscle and no alternative blood supply exists, so a blockage in the A HREF=http://pheeds.com/info/guide/c/co/coronary_circulation.html? title=Coronary circulationcoronary arteries/A reduces the supply of blood to heart muscle.p Most ischaemic heart disease is caused by A HREF=http://pheeds.com/info/guide/a/at/atherosclerosis.html? title=Atherosclerosisatherosclerosis/A.p What is it? ulli Initially there is narrowing of coronary arteries causing A HREF=http://pheeds.com/info/guide/a/an/angina.html? title=Anginaangina/A. /lili The narrowing is mostly caused by fatty plaques lining the wall of the artery. /lili Sometimes a fatty plaque will rupture leading to a A HREF=http://pheeds.com/info/guide/h/he/heart_attack.html? title=Heart attackheart attack/A.
