Is it possible to have any type of heart attack and it not show up in the blood?
Question:
Answers:
1. Pain that is 'on and off' is not a sign of a heart attack, however, females experience heart attacks differently than males a lot of times, and there are many many ways a heart attack can present.
Some people have no pain at all.
Having said that, your pain is probably not a heart attack, but more likely angina, which can be a precursor to a heart attack.
To answer your question: yes, you can have a heart attack and it won't show up on blood work. The enymes they look for are only changed DURING and immediately after a heart attack, they aren't permanant changes.
Your EKG is more likely to show it, because sometimes your EKG changes slightly after a heart attack. However, to show a change they need an old EKG to compare it to.
You could have had anxiety attacks that feel like a heart attack or maybe angina?
Only one blood test has not enough to detect or r/o of acute MI.The stat of art to detect or r/o of mi are order troponin test 2-3 times at 1st 12 hours of chest pain and repeat as needed. .Other test;ck or ck-mb still use .Sure EKG,stress test are also need to the diagnosis.of chest pain.If the MI is old the lab test will back to normal but the ekg will showed some change(scar).
points against a heart attack: 1) your age 2) female (lower risk for coronary syndromes) 3) your symptom duration and pattern is not typical of a heart attack or any coronary syndrome 4) blood exams and stress echo negative
typical anginal pain is usually 1) precipitated by effort 2) usually relieved by rest (unless related to a heart attack) 3) substernal in location 4) usually heavy or tight 5) usually radiates to the left shoulder, inner portion of left arm, up to the jaw line (but not above it), up to the upper part of the belly button (but never bellow it)
chest pain also can originate from a lot of entities
1) inflammation of the rib joints and muscles
2) pleuritic pain (from inflammation of the lining of the lungs, usually due to pneumonia)
3) pericarditis (chest pain usually radiates to the back, worse on lying down)
4) aortic aneurysm (also radiating to the back)
the blood exams for a heart attack include
1) creatine kinase-MB subtype-starts to rise at 6 hours post chest pain, peaks at 24 hours, disappears at 36 hours
2) troponin T, I-starts to rise at 6-12 hours, peaks between 24-72 hours, disappears after 1-2 weeks
so if you did have a heart attack (which i doubt) you're blood might have been extracted outside the time frames i mentioned above.
i suggest you consult your doctor and look for other causes rather than a heart attack.
There are a number of things that can mimic a heart attack. Angina, hiatal hernia, ulcers, gall bladder disease, esophageal spasms, asthma, bronchial spasms, etc., can all project the same discomfort. The only test that is 100 % accurate for the diagnosis of coronary artery disease, is a heart catheterization. You can have a heart attack and the blood work not reflect it. I'd also advise you to have a second opinion. An echo can show if there is any "non-movement" of any part of the heart that may be a result of a heart attack. Hope you do well.
