Coronary Heart disease affects the coronary arteries which supply glucose and oxygen to the heart.

Sometimes, the coronary arteries get blocked (because of blood clots or the lumen has become smaller), so less/ no oxygen or glucose can be supplied to the heart.

. If the blockage is lower down in the artery, then the symptoms will be milder, because a small area of muscle will suffer oxygen deprivation.

This disease can be fatal - as this will cause a heart attack (also known as "myocardial infarction") and the heart will eventually stop beating because the blood supply is completely cut off.

How does the body respond to coronary heart disease?

In response to coronary heart disease (CHD), the body often activates compensatory mechanisms to maintain blood flow and oxygen delivery to the heart. This includes the dilation of coronary arteries and an increase in heart rate to enhance oxygen supply. Additionally, the body may promote the development of collateral circulation, creating alternative pathways for blood flow. Over time, however, these responses can be insufficient, leading to symptoms such as angina or heart attacks as the disease progresses.


How can heart disease damage your heart?

Heart disease can damage the heart in different ways depending on the disease. In CAD (Coronary Artery Disease), blockages in the lumen of the arteries can cause areas of the coronary muscle to shut down due to lack of oxygenation. If the plaques continue to build up in the heart's blood vessels, more coronary muscle shuts down. Undetected, this could lead to death as the heart does not have the strength to pump blood through the body.

What is the effect of coronary heart disease to organism?
