Heart Blood Tests (Cardiac Testing)
What is a Heart Blood Test?
Analysis of a blood sample can provide important information about the heart. Through these tests, some of the more significant blood components may be measured including Apolipoproteins- this protein in abnormal levels promotes atherosclerosis and may increase the risk of coronary artery disease (CAD) or stroke.
This test can also detect homocysteine (an amino acid). Elevated levels of this in your blood levels may promote atherosclerosis and CAD, as well as blood clots that can lead to a heart attack or stroke.
A heart blood test can also detect C-reactive protein (CRP) and perform Cardiac enzyme studies, both of which can be damaging to those with existing problems and for those with new symptoms.
Purpose of the Heart Blood Test
- Apolipoproteins, homocysteine and CRP are measured to evaluate the individual risk or coronary artery disease.
- Cardiac enzymes help to detect the presence of a recent or ongoing heart attack. This helps to plan treatment plans and medication.
Before and After a Cardiac Blood Test
You will be asked to sustain from eating or drinking anything apart from water, for 12 to 14 hours before the test to make sure the results are accurate.
The blood will be drawn from a vein in your arm usually and sent to the laboratory for analysis. You should be able to carry on your day as normal following your test.
