16 yr old son, heart palps, dizzy, nauseas troponin

16 yr old son, heart palps, dizzy, nauseas troponin <o.10 and creatine kinase 389 h.  Er doc said probably food poisoning or virus.Could that be?

Cardiologist needed : I wonder if your son has seen a cardiologist for these things. Cardiac conditions are not uncommon in youngsters, and these kinds of symptoms warrant a thorough evaluation. Do not hesitate to seek help at your local emergency room or call 911 if you are concerned about a cardiac condition - especially a new or sudden onset of cardiac symptoms. ...Read more

Troponin (Definition)

Troponin is an enzyme found in heart muscle, which is involved in the muscle fiber's ability to contract. It is extremely specific to heart muscle, and hence if levels are elevated in the blood, it points very confidently toward heart muscle damage as a cause of patient's symptoms. In fact, it is the test that is used to definitively ...Read more

Creatine kinase vs creatinine, is there a difference between them?

Yes: Creatine kinase is a muscle enzyme that is measured to assess heart damage (the mb isoenzyme form) or skeletal muscle damage (the mm isoenzyme). Creatinine is an endogenous peptide, present in everyone, that is cleared by the kidneys and is measured in clinical practice to estimate kidney function. ...Read more

Bun is 28, creatinine 1.16. Egfr 61. Healthy 35 yr old caucasian female. Only problem is benign fasciculations x1 year. Normal creat kinase. Why?

Stop worrying: I am going to assume that you feel well and are asking why your estimated GFR is lowish and your BUN a bit high. I like to eat protein and my BUN is always high. Are you athletic? When i was lifting daily my creatinine was 1.6-1.7; or a Motrin tablet or minimal kidney disease may be raising yours. I suggest repeat in a year and stop fretting over a number in the meantime. ...Read more

What causes creatinine kinase levels to rise with muscle weakness?

What causes creatinine kinase levels to rise with muscle weakness?

Damage to muscle: The correct term is creatine kinase (ck). Creatinine is something else. Useful to know: most "muscle" weakness is actually caused by nerve, not muscle, malfunction. True muscle weakess: myocytes (muscle cells) contain lots of the enzyme ck. Low levels are found in blood normally. Damage to myocyte cell membranes from a variety of causes causes leakage of ck into the blood. Recovery->normalization. ...Read more

Would normal troponin 1, myoglobin, ck-mb & creatine kinease levels 100% rule out heart attack?

Would normal troponin 1, myoglobin, ck-mb & creatine kinease levels 100% rule out heart attack?

You have anxiety: You do not have heart troubles. The tests are negative because this is not your heart. Any good doctor can tell you this. You are carrying your stress in your chest muscles and not breathing well. Your heart is fine. ...Read more
