Coronary heart disease CHD , or coronary artery disease, develops when the coronary arteries become too narrow. The coronary arteries are the blood vessels that supply oxygen and blood to the heart. CHD tends to develop when cholesterol builds up on the artery walls, creating plaques.
Coronary artery disease CAD does not usually cause symptoms until it becomes advanced. Subtle symptoms can include dizziness, indigestion-like sensations, fatigue, and lack of energy. More noticeable symptoms of CAD include shortness of breath and chest pain. These are all warning signs of a heart attack and you should seek medical attention if you have any of the signs or symptoms of CAD. In general, symptoms of CAD are related to narrowing of the blood vessels of the heart, which can intermittently prevent the heart muscle from receiving optimal blood supply.
Coronary artery disease CAD reduces the flow of blood to your heart. It happens when the arteries that supply blood to your heart muscle become narrowed and hardened due to fat and other substances accumulating into a plaque where the coronary artery is injured atherosclerosis. This can cause your heart to become weak and beat abnormally. Over time, it can lead to heart failure. Chest pain, shortness of breath, and other symptoms are associated with CAD.
Coronary artery disease is caused by plaque buildup in the wall of the arteries that supply blood to the heart called coronary arteries. Plaque is made up of cholesterol deposits. Plaque buildup causes the inside of the arteries to narrow over time. This process is called atherosclerosis. It is sometimes called coronary heart disease or ischemic heart disease.
Coronary artery disease CAD , also called coronary heart disease CHD , ischemic heart disease IHD ,  or simply heart disease , involves the reduction of blood flow to the heart muscle due to build-up of plaque atherosclerosis in the arteries of the heart. Usually symptoms occur with exercise or emotional stress , last less than a few minutes, and improve with rest. Risk factors include high blood pressure , smoking , diabetes , lack of exercise, obesity , high blood cholesterol , poor diet, depression , and excessive alcohol. Ways to reduce CAD risk include eating a healthy diet , regularly exercising, maintaining a healthy weight, and not smoking.
The most common symptom of coronary artery disease is angina also called angina pectoris. Angina is often referred to as chest pain. It is also described as chest discomfort, heaviness, tightness, pressure, aching, burning, numbness, fullness, or squeezing.
Coronary artery disease CAD is the most common type of heart disease. It is the leading cause of death in the United States in both men and women. CAD happens when the arteries that supply blood to heart muscle become hardened and narrowed.
