Are arms and legs in competition for cardiac output?

Cardiac Output: The body will preferentially direct cardiac output to organs it deemes most vital for sustaining life. This is in (relative) order: brain, heart, kidneys, gut, muscle and skin. There is no real competition between upper and lower extremities, but rather distribution based on muscle activity and intensity. Fun question! ...Read more

thank you in advance for your t

Yes, : Yes, very definitely. The troponin test is used to help diagnose a heart attack, to detect mild to severe heart injury, and to distinguish chest pain that may be due to other causes. An elevation in combination with certain changes in the electrocardiogram can be very specific for a heart attack. Troponin values can remain high for 1—2 weeks after a heart attack. Troponin may rise following strenuous exercise, although without signs and symptoms of heart disease, it is usually of no significance. Troponin levels may also be elevated with acute or chronic conditions such as myocarditis (inflammation of heart muscle), congestive heart failure, severe infections, kidney disease, and certain chronic inflammatory conditions of muscles and skin. Some pains in the arms and less likely in the legs may be indicative of a cardiac problem. Best to have this checked by your doctor as soon as you can. ...Read more

I am constantly itchy at night, especially in my arms and legs. What can that be from?

Typically : Typically itching is due to an allergic reaction. The hard part is trying to figure out the cause. If it's at night then maybe it is something you are eating or drinking in the evening, a new blanket or sheets, possibly even a new detergent or soap you are using. Eliminating your exposure and foods one at a time will be time consuming yet may help reveal the cause. You could also visit your doctor for an evaluation to rule out other causes and possibly allergy testing if deemed necessary. Good luck. ...Read more
