Is one troponin t test within 7 hours of symptoms enough to rule out heart attack. it as neg but i'm still having symptoms. i read a series sb done.

NoEasyAnswerToThis: There are no hard & fast rules.Each case must be evaluated on its own.Yes,in certain circumstances one troponin 7 hours after onset of symptoms can rule out some heart damage;but not necessarily a'heart attack,' per se.You can have a bad headache without having a stroke,right?Also depends on your personal story,family history,lifestyle,diet,activities,stress factors, smoking, drugs.Find a good doc
