Coronary artery aneurysm
Coronary Artery Aneurysm
Coronary artery aneurysm (pronunciation: kuh-ROH-nuh-ree AR-ter-ee an-yuh-riz-uhm) is a medical condition characterized by an abnormal dilation or bulging of a portion of the coronary artery. The etymology of the term comes from the Greek words koronaria, meaning crown, arteria, meaning windpipe, and aneurysma, meaning dilation.
Definition
A coronary artery aneurysm is defined as a coronary artery dilation that exceeds the normal diameter by 50 percent. It is a rare condition, affecting approximately 1.5% to 5% of patients undergoing coronary angiography.
Causes
The most common cause of coronary artery aneurysm is atherosclerosis, a disease in which plaque builds up inside the arteries. Other causes include Kawasaki disease, a rare condition in children that causes inflammation in the walls of some blood vessels in the body, and connective tissue disorders, which can weaken the artery wall.
Symptoms
Most people with a coronary artery aneurysm do not have symptoms until the aneurysm becomes large or bursts. Symptoms may include chest pain, shortness of breath, fatigue, and irregular heartbeat.
Diagnosis
Diagnosis of a coronary artery aneurysm is typically made through imaging tests such as a coronary angiogram, which can visualize the coronary arteries and detect any abnormalities.
Treatment
Treatment for a coronary artery aneurysm depends on the size and location of the aneurysm, as well as the patient's overall health. Options may include medication to lower blood pressure and reduce the risk of rupture, and in some cases, surgical intervention may be necessary.
