Answer 1

The above terms are used in case of improper functioning of the heart. If the heart doesn’t function properly, it can result in a person’s death. All these diseases can result in chest pain.

Complete answer:
The heart is the major organ for the circulation of blood in our body. It pumps the oxygenated blood for all tissues and cells through the channel of blood vessels. The heart works in the association of the lungs which oxygenates the blood. Oxygen is very essential for the production of energy and metabolism. If the heart is not working properly or fails there arise certain conditions which can even be fatal. Let us discuss the various heart diseases.

Angina pectoris	Heart Failure	Cardiac arrest	Heart attack
It is the condition that arises due to an insufficient supply of oxygen to the muscles of the heart.	The heart regularly pumps blood. The contraction and the relaxation of the heart is termed systole and diastole. If the systole and diastole don’t happen adequately, it results in heart failure.	It is the condition in which the heart stops beating.	In this the cardiac muscles are stretched out.
It leads to severe and crushing pain in the chest.	It leads to fatigue, shortness of breath, rapid heart rate and swollen legs.	It results in the sudden death of an individual as the oxygen is not supplied to vital organs.	It causes severe pain and also heart failure.
It happens when the arteries are narrowed or blocked.	It can be caused by a congenital heart defect.	It happens when the electrical functioning of the heart is not proper.	It is caused by the blockage of arteries.

Note: The heart diseases is also known as cardiovascular disease. Heart diseases can be caused due to congenital factors and also because of lifestyle factors. Diabetes and high cholesterol lead to the thickening of the blood as well as the walls of the arteries.
