Symptoms may go unrecognized at first, or they may only occur when the heart is beating hard like during exercise. As the coronary arteries continue to narrow, less and less blood gets to the heart and symptoms can become more severe or frequent. Coronary artery disease signs and symptoms can include:  Chest pain (angina). You may feel pressure or tightness in your chest. Some people say it feels like someone is standing on their chest. The chest pain usually occurs on the middle or left side of the chest. Activity or strong emotions can trigger angina. The pain usually goes away within minutes after the triggering event ends. In some people, especially women, the pain may be brief or sharp and felt in the neck, arm or back. Shortness of breath. You may feel like you can't catch your breath. Fatigue. If the heart can't pump enough blood to meet your body's needs, you may feel unusually tired. Heart attack. A completely blocked coronary artery will cause a heart attack. The classic signs and symptoms of a heart attack include crushing chest pain or pressure, shoulder or arm pain, shortness of breath, and sweating. Women may have less typical symptoms, such as neck or jaw pain, nausea and fatigue. Some heart attacks don't cause any noticeable signs or symptoms.
