Can You Explain Why Troponin Levels Increase When There Is Cardiac Damage
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
Expert consultation: I assume you were/are hospitalized for this. The pneumonia should be treated. The pneumonia could have been severe enough to cause heart strain leading to an elevated troponin. I also assume an EKG was done. You are young to have heart disease. Discuss with your doctor the need for further work up including echocardiogram, lipid panel. Possible referral to cardiology for heart catheterization ...Read more
I have had some lab work to find out my troponin levels and they were .13 and the other one is .18 is this normal or are these values high?
That depends: On the type of troponin level tested: trop-i or trop-t. Generally anything 0-0.1micrograms/l is within normal range for trop-t, trop i is <10 micrograms/l. It also depends highly on the labs "normal ranges" as these differ from lab to lab. Always good to stick with the same lab and methodology to follow trends in labs. If at the er for chest pain to rule out mi, they would look at ekg's too. ...Read more
Troponin: Not sure why a troponin was drawn in a pneumonia patient. If the patient has no heart attack symptoms, would just treat the pneumonia and evaluate the cardiac status after the pneumonia resolves. If heart attack symptoms, might be heart attack and heart failure not pneumonia. Should ask the doc what's the story. ...Read more
Few things: Troponin is a marker of several heart disorder including heart attack. Other cardiac conditions such as inflammation of the heart muscle, inflammation of the sac around the heart (pericardoum) also can cause troponin release in the blood. Troponin is increased in cardiac contusion, defibrillation of the heart and some cardiac procedures. It is positive up to 10-14 days after the injury. ...Read moreSee 1 more doctor answer

Yes and no: Troponins as you likely know by asking this question is an enzyme liberated into the bloodstream by damaged myocardial cells. While pneumonia and a myocardial event are technically separate entities..They can be linked. Patients with pneumococcal pneumonia are at substantial risk for a concurrent acute cardiac event, such as mi, serious arrhythmia, or new or worsening chf. ...Read more
