Does the left hand numb have anything to do with the heart?

The left hand numbness has a certain relationship with the heart. The

heart is an organ of the human circulatory system. It can transmit blood pressure to various parts of the human body through continuous relaxation and contraction. The heart is affected by infection, trauma and other factors, resulting in decreased cardiac function, which in turn will cause reduced cardiac pumping. Due to insufficient blood perfusion in the left hand, it will cause local nervous dysfunction, and then hand numbness symptoms.

If the patient's heart function is normal, hand numbness is mostly related to improper position, hand trauma, infection and other factors. Medical examinations such as physical examination and laboratory examination are required to confirm the diagnosis in time.
