The article was professionally consulted by Doctor Nguyen Van Duong, Cardiology Center - Vinmec Central Park International HospitalCoronary artery disease, also known as ischemic heart disease, is a narrowing of the coronary arteries due to the presence of atherosclerotic plaques. Coronary artery disease can lead to a higher risk of heart attack and other serious cardiovascular diseases.
To diagnose coronary artery disease, one or more of the following methods can be applied:
1. Electrocardiogram
This is the simplest measure to help detect the signs of coronary heart disease. Electrocardiograms are electrical impulses during the functioning of the heart. Through the electrocardiogram, the patient will be detected the manifestations of myocardial ischemia, myocardial necrosis as well as complications of cardiovascular disease such as thickening of the heart wall, dilated heart chambers and arrhythmia.Electrocardiogram is a non-invasive, simple, inexpensive and very fast test. However, the correlation of ECG and coronary artery disease is not always accurate. There are cases of patients with coronary artery disease but the electrocardiogram shows no abnormal signs or cases without disease but the electrocardiogram changes.
2. Echocardiography
This is a test with the principle of operation based on ultrasound waves to create images of the heart when the heart is working, this measure aims to investigate the movement of the heart wall, heart function as well as heart valves.When a patient has coronary artery disease, the myocardium supplied by that coronary branch will fall into hypoxia and dyskinesia such as hypoactivity or inactivity. Echocardiography often detects coronary artery disease in the late stages because at this time, movement disorders of the heart chambers have appeared.
This is a non-invasive technique, but it requires full, modern machinery and qualified doctors.

3. Stress ECG
The patient is asked to run or walk on a treadmill and an electrocardiogram device is attached to the body. At this time, the patient's body has to work hard, which increases the demand for blood in the heart. If the patient cannot walk or run, the doctor will prescribe medication to increase the heart rate. The exercise electrocardiogram is used to check whether the heart is receiving enough blood.In addition, some other types of stress tests, such as stress echocardiography, stress myocardial scintigraphy, can be used.
4. Diagnostic Imaging
Imaging studies include:Multi-segment computed tomography coronary artery disease. Cardiac magnetic resonance imaging. Cardiac perfusion radiography. These techniques will produce images of coronary anatomy, degree of coronary calcification, degree of coronary stenosis, location of coronary stenosis, coronary malformation, degree of myocardial survival...

5. Cardiac catheterization and coronary angiography
This is the most modern technique to diagnose coronary artery disease, also known as percutaneous coronary angiography. Cardiac catheterization and coronary angiography were performed in the interventional cardiology room with assistive devices and fluorescent screens. The doctor will proceed to insert the catheter into the patient's heart through the radial or femoral artery. The patient is then injected with contrast through the catheter to the coronary artery. From there, it is possible to assess the location of the stenosis, the degree of stenosis, the shape and size of the coronary arteries on the fluorescein screen.Unlike the above methods, this is an invasive technique and causes bleeding. However, the patient will not have to experience pain because there is no need for anesthesia but only local anesthesia, leaving few serious complications.
