Angina is the result of reduced flow of blood to an area close to the heart. This is most often due to a coronary artery blockage. Sometimes, other forms of cardiovascular disease (CAD) or unchecked high blood pressure can cause angina.
CAD affects the coronary arterial blood vessels that carry oxygen-rich blood to the heart’s lean muscle. It is caused by the slow buildup over time of fatty deposits called plaque. This is called arteriosclerosis. The plaque hardens and increases in size thus leading to narrowed arteries. Other parts of the plaque buildup is softer and more likely to break apart or form cracks and trigger blood clots.
The accumulation of plaque around the inner of the arteries could cause angina in two different ways. First, by narrowing your artery enough where the blood flow is greatly decreased and secondly by causing blood clots which are partially or maybe totally block the artery.
Stable angina is usually caused by exertion from physical exercise. This type of angina triggers thepain and distress of firm angina. Severely narrowed arteries may continue to allow more than enough blood to reach the heart while the body’s demand for oxygen is low, such as while you are lying down. With a physical work out such as running up a hill or even climbing a stairway, the heart works harder because the body is demanding more oxygen.
Unstable Angina is brought on by blood clots that partially or totally block an artery. If the plaque buildup inside an artery cracks or perhaps breaks off, blood clots may form. This situation creates an even larger blockage of the artery. The clot may grow big enough to l completely prevent the flow of blood through the artery and cause a heart angina episode or even a heart attack. Blood clots could form and then partially dissolve, as well as later grow larger again. Chest soreness or angina can occur whenever a clot obstructs the blood flow in an artery.
Variant angina is an extremely rare form of angina pectoris that is caused by a spasm in a coronary artery. While the other types of angina generally occur in people with CAD, variant angina may occur in those with or without the condition. The primary symptom of variant angina is severe pain in or around the chest, shoulders, jaw, neck, back, or arms. The spasm cause the walls of the artery to tighten thus narrowing your artery, causing the blood flow to the heart to slow or even stop.
