The Cardiovascular system is made up of the heart and the blood vessels that irrigate it. The blood is pumped from the heart through the blood vessels to the whole body system.
The arteries that supply blood to the heart are called coronary arteries. When these arteries are blocked or clogged principally by cholesterol clinging to the arteries walls. There is not enough oxygenated blood reaching the heart which can leave a permanent injury on the heart.
Symptoms: The symptoms of blood stoppage are strong sharp pain in the center of the chest occurring suddenly and with great pressure (most significant symptom).
Pain can spread to the neck, the shoulder, the arm and the upper part of the stomach. Also, it can merely stay in the center of the chest. Generally, attacks last for 2 minutes. When there is a partial or temporary obstruction of the coronary artery, there occurs a strong pain known as angina pectoris (generally occurs after exercise or strong exertion).
The Heart Attack occurs due to the lack of oxygenated blood and it is permanent killing part of the cardiac muscle. On the other hand, Angina Pectoris causes temporary and reversible damage and that stops within 1 to 2 minutes with rest.
