Heart Attack ” How is it Different From Angina?
Many people get heart attacks and angina confused when they are, in fact, two different (but related) conditions that affect the heart. In what follows, you will come away with a better understanding of the anatomical differences between the two of them.
It is beneficial to find out more about the anatomy of the heart so that you can discern heart attack from angina. The outside walls of the heart consist of muscle, and there is a wall of muscle that passes through the center of the heart. This divides the heart into two parts. However, the two parts are further separated in half again, resulting in four chambers.
The right and left sides are further separated into two parts on each side. The tops chambers are called the atria, and the bottom chambers are called the ventricles. Blood returns from blood vessels in the body and enters the right atrium. Because it has just returned from providing the body with oxygen, when blood returns to the right atrium, it is low in oxygen. It then passes through to the right ventricle, and the right ventricle then pumps the blood to the lungs, where it becomes oxygenated. This oxygen-rich blood then returns to the heart through the left atrium, passes through to the left ventricle where it is pumped to the rest of the body and supplies your tissues and organs with oxygen.
Just like your heart supplies blood and oxygen to all your body parts, it also has to supply oxygen to itself too. The way it does this is through the coronary arteries that are found on its surface. These coronary arteries are involved when a heart attack or angina occurs.
In both heart attack and angina, the coronary arteries have become narrowed usually due to atherosclerosis. Atherosclerosis is a fatty build-up that occurs within the walls of the arteries.
When someone has angina, this means that there is less oxygen that gets to the heart through the coronary arteries, but there is not a complete blockage of the coronary arteries. Angina can result in weakening of the heart over time, making it a less effective pump. Take note of angina, because even though it is not a heart attack, you could have a heart attack in the future. People who have also had heart attacks in the past can also suffer from angina.
In contrast, a heart attack results when there is total blockage of a coronary artery. As a result, no blood at all gets to that part of the heart muscle. This means the heart muscle can die.
In conclusion, angina and heart attack is not the same thing. They both involve the arteries of the heart that supply it with oxygen, but they are still two different types of heart disease.
