Dopamine is a substance secreted by the body itself to regulate the nervous system, cardiovascular system and renal system, etc. There is no such thing as a benefit, it is particularly unique in its regulatory effects.
The human brain, adrenal medulla and other parts of the body can be secreted dopamine, dopamine can also be used as a kind of α, β adrenergic receptor agonist drugs to treat various diseases. Dopamine belongs to the catecholamines, which can act on the heart to excite the beta receptors of the heart, producing a positive effect on the heart, resulting in a faster heart rate and increased myocardial contraction, which can lead to an increase in cardiac output.
Excessive secretion of dopamine may lead to arrhythmia, etc., and too little secretion may lead to a decrease in myocardial contractility or even serious consequences such as shock. Clinically, dopamine is often used as a drug to treat shock syndrome caused by myocardial infarction, severe trauma, congestive heart failure, etc. It is also important to note that hypovolemia must be corrected before applying dopamine.
