Blood tests, also called biomarkers, play an important role in the diagnosis of myocardial infarction and myocarditis, heart failure, and arteriosclerosis. White blood cell count, CPK (creatine phosphokinase), cholesterol level, blood sugar level, CRP, etc. are also important biomarkers that have been used for a long time. In particular, there are tests called troponin and BNP, which are typical ones that are frequently used.
1. Troponin
In myocardial infarction, the heart muscle becomes necrotic. When cardiomyocytes break down, myocardial deviation enzyme flows into the blood. There are several types of enzymes, but recently, the high-sensitivity troponin test, which can measure the enzyme troponin with high sensitivity, is very widely used for the rapid diagnosis of myocardial infarction. Depending on the size of myocardial infarction, the value may be high for 2-3 to 5-6 days after the onset. According to various reports, both sensitivity and specificity are about 90-95%, and myocardial infarction can be diagnosed with extremely high accuracy.
2. BNP or NT-proBNP
The blood test values of BNP and NT-proBNP, which are one of the blood sampling items, increase when the heart is strained. It is used when diagnosing heart failure and determining the effect of treatment, but it is also affected by age, renal function, etc., so it is an index with large individual differences in the numerical value.
