Coronary angiography

Coronary angiography is an auxiliary test used to check whether arterial blood vessels are normal. Coronary angiography is an effective method to diagnose coronary heart disease. The catheter is inserted through the femoral femoral artery or other peripheral arteries and sent to the ascending aorta, and then the left or right coronary artery is explored for insertion, and a contrast agent is injected to make the coronary arteries develop. It can more clearly reveal the position, extent and extent of coronary anatomic deformities and obstructive lesions. Coronary angiography is currently the only method that can directly observe the morphology of coronary arteries, and the medical community calls it the "gold standard". The corresponding symptoms can be judged by the above-mentioned instrument inspection.
