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 moreSee 1 more doctor answer
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
If multiple troponin levels are normal, how unlikely is a person to be having acute HF & Conjestive HF?
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

Sometimes in ER my troponin levels are high sometimes not but they say there is no heart prob. I never know when to go to er?
Damaged heart muscle: If heart muscle cells r damaged, troponin will leak into the blood + levels will rise. However, the muscle damage may be caused by several diseases, not the least of which is coronary artery disease (c article via link below 4 details) http://www. Ncbi. Nlm. Nih. Gov/pmc/articles/pmc1860726/ bottom line? Troponin levels r a sensitive + specific indicator of heart muscle damage from any cause. Dr mike. ...Read more
Heart muscle enzyme: Troponin is a heart enzyme that is released in the blood when the heart is under strain. Elevated levels of this enzyme in the setting of chest pain and ekg changes usually mean that an individual is having a blockage in the blood vessels that supply blood to the heart. ...Read moreSee 1 more doctor answer
If someone dies of heart failure, ANY TYPE of heart failure, will there be a rise in troponin levels?
Troponin: Troponin I is a marker for acute ischemia of heart. However we also see it in patients with kidney failure. So it will not be prudent to say that if Troponin I are elevated that specific for heart failure. As heart failure can be due ischemic or non ischemic causes. ...Read moreSee 1 more doctor answer
Sometimes I go to ER with chest pains and my troponin levels are up sometimes not but they always say my heart is fine?
Unclear: I would be concerned about troponin levels going up with chest pain (how high?) but if you already had a cardiac cath, and if you were told your coronary arteries are normal that is very good news. Even without blockages, some patients have issues with cocaine, arterial spasms, clots, uncontrolled hypertension, or other conditions but only your doc can give you a diagnosis from a complete history. ...Read moreSee 3 more doctor answers
