Doctor insights on: Can You Explain Why Troponin Levels Increase When There Is Cardiac Damage

Share

Troponin (Definition)

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

What to do if I have high bp) cause hypoventillation (i.e: why does stimuation of the arterial baroreceptors cause a decreased breathing rate)?

What to do if I have high bp) cause hypoventillation (i.e: why does stimuation of the arterial baroreceptors cause a decreased breathing rate)?

Wrong: You have a different physiology text than mine! Hypoventilation with fall in pO2, rise in pCO2, and fall in pH - all stimulate arterial chemoreceptors in the carotid and aortic bodies to increase breathing rate. There is no effect on baroreceptors which respond to changes in BP. ...Read more

Do know your crp! if persistently elevated, it is an indicator of joint damage and potential ashd. Please explain what does that mean ?

Do know your crp! if persistently elevated, it is an indicator of joint damage and potential ashd. Please explain what does that mean ?

CRP & inflammation: C-reactive protein is an indicator of inflammation in the body, which can lead to joint damage, heart disease, and many other conditions including dementias. You may have seen a tiptap suggesting you know the results of this lab test in your own case. Elevated levels need to be reviewed more carefully by your doctor, since they can be linked to damaging body processes http://tinyurl.Com/7gb72pq. ...Read more

What reasons can you think of to explain that cooler temp decreases heart rate?

What reasons can you think of to explain that cooler temp decreases heart rate?

Decreased metabolism: Colder temps decrease hr through a variety of mechanisms. #1 decreased metabolism in the skin and extremities. #2 peripheral vasoconstriction reduces circulatory demand. There may be a central effect as well although I am not sure. ...Read more

If heart enzymes are high in blood work, what does it mean?

If heart enzymes are high in blood work, what does it mean?

Depends: Which "heart enzymes" and when they are noted to be how high are all potentially important markers of underlying disease and prognosis. Although there are some patient who "normally" have high cardiac enzymes, these blood tests are the ones doctors usually use to indicate heart muscle damage, and thus make a diagnosis of myocardial infarction, or "heart attack", versus ischemia (without damage). ...Read more

What does it mean to have high dhea sulfate levels (elevated adrenal hormones)? What are the problems associated with this? What can it lead to?

What does it mean to have high dhea sulfate levels (elevated adrenal hormones)? What are the problems associated with this? What can it lead to?

By itself: A high (how high) dheas level may mean nothing at all. I don't know why the level would have been drawn in the first place. It can be significantly (not slightly) elevated in a variety of ovarian or adrenal problems, including pcos. It is also stimulated by certain medications. As a solitary finding without other clinical information, however, it has no value. Talk w/the doctor who ordered it, . ...Read more

Can someone explain the reason why convulsion happens when blood glucose level is so low?

Can someone explain the reason why convulsion happens when blood glucose level is so low?

Low Brain Bloodsugar: Glucose is the main source of fuel for the brain (with the exception of ketones). When blood sugar drops, the brain is deprived of its essential fuel. Ketones can't form when the cause is related to high Insulin levels or other metabolic diseases. Deprived of fuel, the cells of the brain can't function properly: "feeling low", behavior changes, loss of consciousness & seizure in extreme cases. ...Read more

For what reasons might the heart rate drop and BP increase when you have pancreatitis?

Not always : Depend on how severe is the pancreatitis. Mild to moderate inflammation associated with pain will increase hr and BP too. During severe attack of pancreatitis a systemic inflammatory response occur, causing a hyperdynamic response in your body. That will decrease your BP and increase your hr and increase your cardiac output. ...Read more

What to do if i read that hypertension/high blood pressure can be a cause of bradycardia. Why is that?

Several Reasons: Hypertension (HTN) can resulting in ischemia and abnormality of the conduction system of the heart which may slow heart rate. After a head injury HTN and a slow heart rate are signs that there may be increase in brain pressure. There is also a phenomena where correcting a slow heart rate might resolve HTN see link below http://www.Ncbi.Nlm.Nih.Gov/pubmed/7457024. ...Read more

What do elevated CPK levels mean when exercise is not a factor?

What do elevated CPK levels mean when exercise is not a factor?

Muscle or heart : CPK can be released from damaged or inflamed muscles, including the heart muscle. Some muscle diseases that cause weakness and pain in the muscles can elevate cpk, as can any muscle injury (including an injection into the muscle). Heart attacks and other heart muscle injury or inflammation can also raise the cpk. There are tests to determine the source of the cpk. ("fractionation" of cpk). ...Read more
