Pseudo angina pectoris is mostly caused by chest discomfort due to non-cardiac factors rather than myocardial ischemia, and is distinguished from angina pectoris by the triggers, location, nature, and mode of relief.
1. Angina pectoris is mostly caused by increased myocardial oxygen-consuming behaviors such as eating, physical activity, and mood swings.
2. The site is mostly located in the precordial area, posterior sternum, and may have radiating pain to the back, neck, jaw, and left upper limb.
3. The nature of the pain is often a sense of suffocation, pressure, and rarely pins and needles, burning-like non-myocardial ischemia caused by chest discomfort.
4. Stable angina rest or take nitroglycerin can be significantly relieved, myocardial infarction caused by angina pectoris nitroglycerin is difficult to relieve the need for intervention or thrombolytic therapy can be relieved.
To identify angina pectoris and non-cardiac factors causing anterior chest discomfort, you need to go to the hospital and get a clear diagnosis from the clinician.
