Troponin levels may also be elevated with acute or chronic conditions such as myocarditis (heart inflammation), congestive heart failure, nonischemic cardiomyopathy (heart muscle disease), some infections, dermatomyositis, kidney disease, blood clots in the lung, and polymyositis (muscle disease). Also, some patients may experience mild heart damage with no other evidence of a "heart attack" (myocardial infarctionon) - EKG (called not ST elevation MI), pain, etc.
Hopefully you are scheduled for follow up testing - stress test, echocardiogram, and the like. In one study, mortality rate from future problems was 5% in people with negative heart attack diagnosis, but an elevated Troponin I. The rate of "another" MI was 15%!
