what is the cause of coronary artery aneurysm?

Answer 1

A coronary artery aneurysm is caused by weakening of the artery wall which then balloons outward, sometimes putting pressure on nearby tissues and causing blood to pool at that site in the artery. The artery wall weakening is usually caused by plaque build-up which constricts bloodflow, thereby increasing pressure behind the constriction.

Answer 2

Coronar Artery Aneurysm or also called as Kawasaki disease was first described in 1967 by Tomisaku Kawasaki.
Kawasaki disease is a febrile systemic vasculitis predominantly affecting children under the age of 5. The highest incidence is in Japan but is becoming increasingly recognised in the West.

It is defined as a coronary artery dilatation, which can be saccular or fusiform, and exceeds the diameter of the normal adjacent segment or the diameter of the patient’s largest coronary vessel by 1.5-2 times.
The most serious complication of Kawasaki disease is coronary arteritis and aneurysm formation which occurs in a third of untreated patients.
Complication:The prognosis depends on the diameter of the aneurysms; those less than 4 mm normally regress completely while larger ones tend to leave permanent sequelae.
The aneurysms may be complicated by myocardial infarction, with the attendant complications
