    As plaque builds up, your arteries become narrowed. At first you may not even be aware of this silent process, but eventually clogged arteries will no longer be able to supply enough blood to your heart, especially during physical activity or emotional stress. When that happens, you may feel symptoms of coronary artery disease, including:

    Chest Pain

    Also known as angina, chest pain strikes when the heart is not getting enough blood. You may feel pressure, tightness or a squeezing pain in your chest. You may also feel pain in your jaw, neck, shoulders, arms or back. Women are more likely than men to feel the pain in the arms or back or simply be short of breath. Usually, angina occurs during physical activity or stress, and goes away with rest.

    Shortness of Breath

    Feeling short of breath is another common symptom of coronary artery disease. It occurs when the heart isn't able to pump enough oxygen-rich blood to meet the body's needs. In addition, if you have heart failure as the result of an injured or weakened heart muscle, fluid may back up in the lungs, which will also make it hard to breathe.

    Heart Attack

    During a heart attack, a heart artery becomes completely blocked, and blood cannot get to a portion of the heart. The heart muscle suffers damage and begins to die. The medical term for a heart attack is myocardial infarction, or MI.

    A heart attack can be the result of severe plaque build-up. However, in about half of cases, a heart attack is the first sign that a person has coronary artery disease. In such cases, it's likely that the heart attack occurred when a moderate-sized plaque suddenly ruptured, causing a blood clot to form and block the artery.

    A heart attack often causes crushing pressure and pain in the chest, but it's possible to have a heart attack without experiencing such obvious symptoms, particularly for women. You may experience a feeling of fullness in the chest, or pain in the arms, shoulder, jaw or back. The pain may be mild or severe, and can even feel like indigestion. Other symptoms include sweating, shortness of breath, nausea, vomiting, lightheadedness and fatigue.
