Abstract
Description
Technical Field
[0001] This utility model relates to the field of detection technology of catecholamine metabolites, specifically to a mass spectrometer for determining catecholamine metabolites. Background Technology
[0002] Catecholamines are a collective term for adrenaline, noradrenaline, and dopamine. They are a class of neurotransmitters containing catecholamines and amino groups. The most important catecholamines include adrenaline, noradrenaline, and dopamine. These substances play important regulatory roles in the nervous, cardiovascular, and endocrine systems. Plasma catecholamine metabolite testing reflects the body's catecholamine levels and is significant for the early diagnosis of some cardiovascular and endocrine disorders. Elevated plasma catecholamine metabolite levels may lead to coronary artery constriction, increased myocardial oxygen consumption, and consequently, worsened coronary artery stenosis and myocardial ischemia, increasing the risk of arrhythmias and cardiovascular disease.
