Understanding Coronary Heart Disease


Coronary heart disease (CHD) is a condition when the heart's blood vessels (coronary arteries) are blocked by fat deposits. When added fat accumulates, the artery will add narrowed, resulting in reduced blood flow to the heart.




Reduced blood flow to the heart will result in signs of CHD, such as angina and breathlessness. If the condition is not treated immediately, the arteries will be completely blocked, and cause a heart attack.

Coronary arteries are blood vessels that deliver oxygen-rich blood to the heart. There are two types of coronary arteries, which are equally forked from aortic or large blood vessels, namely:

Main left coronary artery (left main coronary artery/LMCA) – This artery benefits the blood to the left foyer and left chamber of the heart. LMCA is divided into two parts, namely:
-Left anterior descending (LAD) – beneficial to drain blood to the front and left of the heart.

-Circumflex (LCX)-benefit to drain blood to the back and outer side of the heart.

Right coronary artery (right coronary artery/RCA) – This artery delivers blood to the right porch and the right chamber. In addition, RCA includes blood flow to the sinoatrial nodes and Atrioventricular nodes, which adjust the rhythm of the heart. RCA is divided into the right posterior descending and acute marginal artery. With LAD, RCA includes blood to moderate members of the heart, and septum (wall separator between the right chamber and left chamber of the heart).
Based on WHO data, coronary heart disease is one of the highest causes of death in the world. In th. 2015, recorded more than 7 million people die due to CHD. While in Indonesia, more than 2 million people are affected by PJK in th. 2013. Of these, PJK is more common in the age range of 45-54 years.
