<unk>  is a rare disease that occurs in only 0.3-4.9% of people in North America.<unk>  is characterized by the enlargement of a coronary artery to 1.5 times or more than its normal diameter. The disease is commonly asymptomatic and is normally discovered when performing tests for other conditions such as coronary artery disease, stable angina and other acute coronary syndromes.<unk>  occurs 4 times more frequently in males than in females and in people who have risk factors for heart disease such as smokers. While the disease is commonly found in patients with atherosclerosis and coronary artery disease, it can occur by itself and in both cases, it can cause health problems. The disease can cause the heart tissue to be deprived of blood and die due to decreased blood flow, and blockages due to blood clots or spasms of the blood vessel. This blood flow disruption can cause permanent damage to the muscle if the deprivation is prolonged.<unk>  also increases the chance of developing large weak spots in the affected coronary arteries, or aneurysms that can rupture and result in death. The damage can result in angina which is pain in the chest and is a common complaint in these patients.
