What does it mean if troponin levels drop below 40?

This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

Recently, I had unusual palpitations. My doctor diagnosed it as abnormal heart rhythm and referred me to a cardiologist, who suggested a few tests. The blood test report shows that the troponin levels have dropped below 40. Currently, I am using tablet Colchicine 0.5 mg once daily. I am attaching the test reports for your reference. Kindly advise.

Thank you.

Hello,

Welcome to icliniq.com.

I understand your concern and would be happy to help. I have checked your ECG (electrocardiogram) and other test reports (attachments removed to protect the patient's identity). All the investigations are within the normal range except for the slightly elevated troponin levels. Also, the ECG shows evidence of supraventricular beats. This does not sound serious. Do not be worried. Do let me know if you are still getting palpitations. Also, is there a complaint of dizziness or shortness of breath?

I hope this helps.

Please revert so I can assist you further.

Thank you.

Patient's Query

Hi doctor,

Thank you for your reply.

Thank you for your response. I have palpitations when I sit, listen to lectures, or even when I watch a movie. However, sometimes I do not have them. My doctor has diagnosed it as mild myocarditis. He also said that another possibility could be an anxiety attack. I had my third shot of the COVID 19 vaccine six months back. Are the palpitations due to stress or overthinking? Kindly advise.

Thank you.

Answered by Dr. Isaac Gana

Hello,

Welcome back to icliniq.com.

Based on your reports, I do not see any proof to suspect myocarditis.

However, I suggest you see a physician who can prescribe beta-blockers to you, as it can help you.

I hope you found this helpful. Kindly revert in case of further questions. Best regards.

Patient's Query

Hi doctor,

Thank you for your reply.

Thank you for your clarification. My sister, a GP (general practitioner), has suggested me to take tablet Propanolol once daily. I have taken just one tablet. Can I take this medicine, and how long should I continue using it? Also, can I continue HIIT workouts, running, jogging, and hiking? Kindly advise.

Thank you.

Answered by Dr. Isaac Gana

Hello,

Welcome back to icliniq.com.

Tablet Propranolol is a beta-blocker. You need to start using the tablet with a low dose of 10 mg every day for at least two weeks. Once you see an improvement, you can reduce the dose to 5 mg and use for another two weeks. You can continue exercising. However, I suggest you do moderate exercises as of now.

I hope this helps.

Kindly revert in case of further questions.

Thank you.

Patient's Query

Hi doctor,

Thank you for your reply.

I have two questions. Which investigation did he do exactly to conclude myocarditis? Does moderate exercise includes running (running 20 minutes or covering 1.24 miles)? Please help.

Thank you.

Answered by Dr. Isaac Gana

Hello,

Welcome back to icliniq.com.

Your doctor concluded it was myocarditis, most likely based on the echocardiogram (ECG) and cardiac markers. Moderate exercise can include 2 km of running. Better assessment can be done if you can answer the following questions. Have you started exercising? Do you still experience the symptoms?

Patient's Query

Hi doctor,

Thank you for your reply.

I have attached the MRI reports showing no evidence of myocarditis, but some volume is shown lesser. I went for a recent checkup with the same doctor, and he said everything was normal. When I asked the doctor about lower ESV and EDV, the doctor mentioned nothing to worry about.

Please advise.

Thank you.

Answered by Dr. Isaac Gana

Hello,

Welcome back to icliniq.com.

I have gone through your MRI reports (attachments removed to protect the patient's identity). All the parameters in the results are normal. A slight change in end-systolic volume (ESV) and end-diastolic volume (EDV) does not hold any significant value. Perhaps you might be having issues with anxiety. Are you still having chest pain? Thank you.

Patient's Query

Hi doctor,

I do not have any chest pain. I have pain only in the spleen and left rib sometimes. Is this an indicator? Also, can I know if a lower heart rate could be associated with lower EDV, ESV and cardiac output? Kindly help.

Answered by Dr. Isaac Gana

Hello,

Welcome back to icliniq.com.

There is no known association between lower heart rate with lower EDV (end-diastolic volume), ESV (end-systolic volume), and cardiac output. Better assessment can be done if you can answer the following questions.

  1. Have you taken any pain medication?
  2. What do you mean by an indicator?

Please revert so I can assist you further.

Thank you.
