The purple color of the face is considered to be caused by cold stimulation, heart disease, pulmonary embolism and so on.
1. Cold stimulation: when the weather is cold, it is easy to cause purple and cyanosis, which is a normal body protection mechanism. Because the cold stimulus will make the blood flow slower, resulting in lower oxygen saturation of peripheral blood vessels, the color of the blood will appear sauce purple, the face will be purple.
2. Heart disease: in the heart failure attack, due to cardiac insufficiency, it will affect the normal blood supply, oxygen supply, and in severe cases, cause pulmonary stasis, resulting in reduced oxygen saturation, easy to make the face purple. Most of the precordial diseases also have purple face or lips.
3. Pulmonary artery embolism: because the embolus blocks the pulmonary artery or other branches, resulting in pulmonary artery embolism, which often causes the patient’s skin to be cold and wet or discolored, and the face tends to turn purple.
Purple face may also be caused by other factors, such as congenital heart disease, valvular disease, hypertension, stenosis and other diseases, it is recommended that the patient go to the hospital in time to do the relevant examination, and cooperate with the doctor for treatment.
