What is angina pectoris before the heart?

Question
Hello doctor,
I have left angina pectoris, especially when lying down, sometimes throbbing in front of my heart. I went to the doctor and he said my electrocardiogram had ST-segment elevation, gave me a coronary angiogram, but I couldn't take it because my heart rate was fast. So the doctor asked me what is the left angina pectoris before the heart? Thank you doctor.

Hello,
With the question “What is angina pectoris before the heart? ", the doctor would like to answer as follows:
You have chest pain and have been to the doctor, have been advised to have a coronary angiogram, which means that the doctor is referring to your problem related to coronary artery stenosis / occlusion.
The problem related to coronary stenosis / occlusion, anyway is a very important issue and needs to be clarified immediately, whether there is stenosis or not coronary stenosis. If the coronary arteries are severely narrowed, there is a high risk of embolism and acute myocardial infarction, which can be life-threatening.
Coronary angiography can be done in many ways, such as: coronary MSCT, or coronary DSA (which is invasive and requires hospitalization). Situation if your heart rate is getting too fast, your doctor may give you medicine to slow your heart rate so that a coronary angiogram can be performed. You can go to all hospitals in the Vinmec system for advice and treatment.
If you still have questions about left angina pectoris before the heart, you can go to the hospital of Vinmec Health System for further examination and advice. Thank you for trusting and sending questions to Vinmec. Wish you a lot of health.
Best regards!
