The role of coronary angiography

As the pace of life continues to accelerate, more and more people are prone to heart disease. However, heart disease is often caused by our irregular living habits and eating habits. In order to be able to get good treatment for this heart disease, we must diagnose and examine the disease. Coronary angiography is a common examination method, but because we know very little about these medical common sense, we don’t know which diseases require coronary angiography to examine. Let’s take a look at the role of coronary angiography now.

The role of coronary angiography

The main functions of coronary angiography are to evaluate the course, number and malformation of coronary arteries; to evaluate the presence, severity and range of coronary artery lesions; to evaluate changes in coronary artery functionality, including coronary artery spasm and the presence or absence of collateral circulation; and to take into account the evaluation of left ventricular function at the same time. On this basis, interventional treatment can be performed according to the degree and extent of coronary artery lesions; the effects of coronary artery bypass grafting and interventional treatment can be evaluated; and long-term follow-up and prognosis evaluation can be performed.

For diagnosis purposes:

⒈ Chest pain of unknown cause, which cannot be diagnosed by non-invasive examination and clinically suspected of coronary heart disease.

⒉ Unexplained arrhythmias, such as persistent ventricular arrhythmias or new-onset heart block; coronary angiography is sometimes required to rule out coronary heart disease.

⒊ Unexplained left ventricular failure is mainly seen in dilated cardiomyopathy or ischemic cardiomyopathy. Differentiation between the two often requires coronary angiography.

⒋ Recurrent angina after percutaneous coronary intervention (PCI) or coronary artery bypass grafting.

⒌ Before major surgery for congenital heart disease, valvular disease, etc., patients aged > 50 years are prone to coronary artery malformations or atherosclerosis, and intervention can be performed at the same time as the surgery.

⒍ Asymptomatic but suspected of having coronary heart disease, working in high-risk occupations such as pilots, car drivers, police, athletes and firefighters, or requiring medical insurance.

Contraindications to coronary angiography

⒈Allergy to iodine or contrast media.

⒉ Patients with severe cardiopulmonary insufficiency who cannot tolerate surgery.

⒊ Uncontrolled severe arrhythmias such as ventricular arrhythmias.

⒋Electrolyte imbalance.

5. People with severe liver and kidney dysfunction.

With the continuous progress of medical care, many diseases can be cured well. The above is an introduction to the role of coronary angiography. After understanding it, we must go to the hospital for examination and treatment in time when there is a problem with our body. In addition, in order to have a healthy body, we must maintain good living habits in our daily lives, try not to smoke and drink, and also pay attention to a balanced diet.
