What would happen if the coronary artery got blocked?

Answer 1

The coronary arteries is, of which there are actually two one right and one left, are the first ones in the coronary supply, i.e. they are the root suplly coming directly from the aorta. Other than the fact that suply so the heart is only during ventricular diastole (I have attempted to explain the point in other questions) the odd thing about the heart is that its arters are terminal. Of course by this i do not mean they just stop they to still turn into cappilary bweds then veins. What I mean is they to not join up to each other as they do in many other organs. The reason they usually do this is so that if there is a blockage somewehre supply to that region is not cut off. Think about it like a stram with holes in it, if you blow water through the straw is will burst out through all the holes. If there was a blockage somewhere in the straw then water will not come from the holes below the blockage. If you make the straw into a loop and blow water through it, even with a blockage the all of the holes will have water coming out of them still. Well if one of the coronary arteries, as there is no loop, the supply to all the heart that comes after the blockage will stop. This mean the heart will no longer receive any oxygen or nutriengs and will lead to a heart attack.

That usually leads to a heart attack, also known as a myocardial infarction.

Answer 2

The arteries that bring blood to the heart muscle (coronary arteries) can become clogged by plaque (a buildup of fat, cholesterol and other substances). This can slow or stop blood flow through the heart's blood vessels, leading to chest pain or a heart attack. Increasing blood flow to the heart muscle can relieve chest pain and reduce the risk of heart attack. If you are suffering chest pain or other symptoms that may indicate a cardiovascular problem, your doctor will likely want you to undergo an angiogram (cardiac catheterization) to see if your coronary arteriesare blocked by plaque. A blockage can cause a decrease in the supply of blood and oxygen to the heart and over time can lead to debilitating chest pain or a heart attack. If angioplasty proves unsuccessful, the position of the blockage is too difficult to access by angioplasty, or you have severe blockages in multiple major vessels, your doctor may recommend that you undergo coronary artery bypass graft (CABG) surgery.

Answer 3

When one or more of the coronary arteries supplying blood to the heart muscle becomes blocked, the heart may not get enough oxygen and nutrients. If death of heart tissue results, the result is known as a heart attack or myocardial infarction.

Answer 4

If the Coronary vessel becomes block then your heart may be severly damaged.

Answer 5

That would result in the heart not getting any oxygenated blood from the lungs. A heart attack would quickly follow.

Answer 6

Oxygen deprivation to the portion of the heart served by that coronary artery would very likely cause a myocardial infarction (heart attack).

Answer 7

difficulty in breathing smoothly

some time feel chest heavier

Answer 8

A heart attacck called a myocardial infarction happens. Death may follow.

Answer 9

Heart attack!
