Coronary disease is known as coronary heart disease or coronary artery disease. The disease is characterized by a narrowing of the blood vessels that supply blood and oxygen to the heart. According to the National Library of Medicine, coronary heart disease is usually caused by atherosclerosis, which is a condition associated with the build-up of plaque and fatty material on artery walls. The build-up on artery walls causes a narrowing of the arteries, which can slow the blood flow to the heart. Recognizing the warning signs of coronary heart disease can help people make good lifestyle choices and seek treatment.
Angina
Angina is a term used for pain in the chest and is the most common symptom of coronary heart disease. The amount of pain varies among individuals. Angina can feel like the heart is being squeezed and has a heavy feeling. The pain is usually felt under the breastbone but can also be felt in the arms, upper back, stomach and neck. It usually occurs when the body needs additional oxygen in the bloodstream, such as during times of activity or high emotions. With coronary heart disease, the pain will go away after a period of rest.
Oxygen Shortage
Coronary heart disease is a condition that reduces the ability of the heart to get oxygen from the lungs. Physical activity increases the need for oxygen, and people may have shortness of breath as they try to breathe in the extra oxygen the body needs. The reduced ability of the heart to receive oxygen from the lungs can also result in extreme fatigue after physical exertion.
Other Warning Signs
According to the American Heart Association, certain factors can increase the risk of developing coronary heart disease. Being overweight or obese, having high blood pressure and smoking are signs of an increased risk of the disease. High cholesterol levels are an indication of the amount of fatty material in the bloodstream and is a sign of an increased risk of coronary heart disease.
