Is homocysteine 55 serious?

The normal range of homocysteine is 5-15μmol/L. Homocysteine 55μmol/L indicates that the level is elevated. Whether it is serious or not should be judged according to the cause of the increase.

Homocysteine is an intermediate product of methionine and cysteine metabolism, which is easily affected by diet. If a large amount of high cholesterol food is eaten before the examination, homocysteine can be elevated to 55μmol/L, which is generally not serious and can return to normal without special treatment. However, if it is caused by coronary atherosclerotic heart disease, acute myocardial infarction, etc., it is more serious. If the treatment is not timely, it may cause arrhythmia, heart failure, etc., or even life-threatening.

Patients need to further improve cardiac ultrasound, coronary angiography, etc. to confirm the diagnosis.
