What Tests are generally required before Cardiac Angiogram?

Static electrocardiogram: It is the most common clinical examination.

1. Electrocardiogram

Static electrocardiogram: It is the most common clinical examination. It can detect changes in the patient's heart activity signals and formulate relevant treatment plans, but its limitations are also relatively large. It can only display the heart signals at the time of the examination. If there is no disease at that time, the problem cannot be clearly shown.

Holter electrocardiogram: also known as "treadmill exercise test", it is more sensitive and accurate than static electrocardiogram, and the cost is relatively low. During the examination, patients need to walk on the movable tablet to record relevant values, so as to detect various changes in the heart in time. Anomalies that provide strong direction for other checks.

2. Heart ultrasound

Color Doppler ultrasound is a relatively comprehensive examination. It can see changes in the structure, size, and thickness of the heart, and can also understand the strength of the heart’s ejection ability to assist in the diagnosis of heart failure.

3. Coronary CT

Plaques inside coronary vessels can be observed to evaluate the degree of vascular stenosis, giving doctors and patients a certain basis for judgment to distinguish whether the situation is critical, but compared with coronary angiography, its accuracy is not high, and it can only determine whether there is the stenosis is blocked, but the extent and location cannot be clearly determined.

Angiography is different from other examinations. It is an invasive examination method, which will bring certain risks to the patient's body and must be cautious.

Coronary angiography is indeed the gold standard for the diagnosis and treatment of coronary heart disease, but not everyone needs angiography when the heart is abnormal, an imaging examination is required.
