===Meaning===
[[File:CHDDiagram.png|right|300px|thumb|A [[diagram]] showing the build up of a [[Cholesterol Plaque]] in a [[Coronary Artery]].]]
'''Coronary Heart Disease''' is a [[Non-communicable Disease|non-communicable disease]] in which the [[artery|arteries]] that supply the [[heart]] with [[oxygen]] become narrower because of the build up of [[Cholesterol Plaques|cholesterol plaques]].
===About Coronary Heart Disease===
: '''Coronary Heart Disease''' can lead to a [[Cardiac Arrest|heart attack]].
: A [[Cholesterol Plaque|Cholesterol plaque]] is a lump of fat.
===Risk Factors in Coronary Heart Disease===
: [[Obesity]] and a [[diet]] high in [[fat]] can increase the risk of [[Coronary Heart Disease]].
: [[Smoking]] can increase the risk of [[Coronary Heart Disease]].
: Lack of [[exercise]] can increase the risk of [[Coronary Heart Disease]].
===Treatment of Coronary Heart Disease===
: In a [[Coronary Bypass]] an [[artery]] from another part of the body is cut out and attached to the [[Coronary Artery]] to provide a path for [[blood]] to flow around the blockage.
: A [[Stent]] is a tube which can be placed inside the narrow [[artery]] and then expanded to widen the [[artery]]. The [[Stent]] is left inside the [[artery]] to hold it open.
