  1. Angina is a chest pain when a portion of the heart does not receive enough oxygen rich blood, so what exactly are the causes of angina?  Angina is commonly a symptom of coronary heart disease. Coronary heart disease decreases blood flow in an area of the heart, which causes chest pain. Due to this, the causes of angina are usually about the same as the causes of coronary heart disease.

    Investigators found that coronary heart disease beings when certain influences destroy in layers of the coronary arteries in the body. Influences can include, smoking, a diet rich in fatty foods, high blood pressure, and high levels of cholesterol and sugar in the blood stream.  When arterial damage occurs, the body activates a healing process. As healing sounds like a positive process, healing can cause plaque build up where the walls have been weakened. As plaque builds, it narrows the arteries, potentially blocking or decreasing blood flow to the heart and rest of the body. This is called atherosclerosis. If untreated, plaque can become hard which cause the arteries to become stiff, resulting in a lack of blood flow. On the other hand, plaque can become soft and rupture the artery, causing a blood clot, causing angina pain.

    1. Stable Angina. Demanding exercise is one of the most common activities in the onset of stable angina. As the body works on physically exhaustive activities, such as running and lifting, the heart needs more and more oxygen to complete the tasks. However, the damaged arteries could allow sufficient blood to reach the rest of the body when doing a leisure activity, such as watching television.
    2. Other causes of stable angina are: Increased levels of stress, Continued exposure to high or low temperatures, Large meals, Smoking
    3. Unstable Angina. Clots in the blood that block an artery either partially or completely can cause an unstable angina. A blood clot can form if plaque in an artery causes a rupture. A blood clot can increase in size that may entirely block the artery and cause a potential heart attack. Some blood clots can dissolve away, and form again, causing angina pain each time.
    4. Variant Angina. A variant angina can form in patients with or without coronary heart disease. A spasm in the artery causes the walls of the artery to fluctuate, restricting blood flow 
    5. Causes of variant angina include: Exposure to cold, Stress, Certain medications that tighten arteries, Smoking, Illicit drug use 
    6. Microvascular Angina. Microvascular angina is commonly paired with coronary microvascular disease. Coronary microvascular disease is a heart disease that influences the heart’s tiniest arteries and with reduced blood flow to these arteries, an angina may occur.
    7. Causes of microvascular angina are: Plaque build up, Spasms, Weakened arterial walls 

    As stated, angina can be paired with various diseases. If angina pain is present, please consult a physician.
