How the Blood Tests Help for Detecting Heart Disease
Cardiovascular disease is the top first disease leading to death. For no other reason as many people die in the world as die of heart disease. In the presence of symptoms that indicate cardiovascular diseases, it is necessary to conduct a comprehensive instrumental and laboratory examination to confirm the diagnosis, study the extent of the disease and search for the causes of its occurrence. A wide range of instrumental and laboratory diagnostics is used in cardiology. One of them is the blood test for heart function.

With the help of a blood test, the doctor will find out what exactly prevents your body from living and working normally, what is the state of its individual organs and systems.
Different types of blood test for heart function
The BNP blood test is now becoming the worldwide standard for early diagnosis of heart failure. Determination of the content of natriuretic hormone is carried out in the following situations:
- Screening studies to identify patients with a high probability of having heart failure.
- Diagnostics of its early stages.
- Evaluation of the effectiveness of therapy in patients with this ailment.
- Assessment of the prognosis of the course of the disease in patients with heart failure.
B-type natriuretic peptide is a vasoactive hormone. It is synthesized in myocardial cells, from where it is released as a result of stretching of the ventricular wall. An increase in the level of the natriuretic hormone is a harbinger of an unfavorable prognosis in patients with heart diseases of any etiology.
Troponin I is a globular regulatory protein found in the cells of the heart muscle, which is involved in muscle contraction. Troponin blood test is the best choice for detecting heart attack today, and troponin testing confirms or excludes myocardial infarction in people with heart pain, high blood pressure, and other symptoms that are very similar to those of high-risk stable angina.
Why is a cardiac enzymes test performed?
Cardiac enzymes are measured to:
- Determine your risk of heart attack if you have chest pain, shortness of breath, vomiting, increased sweating, and an abnormal cardiogram;
- Check the success of cardiac bypass surgery;
- Monitor the progress of treatment for blockages and other heart conditions.
If possible, it is advisable to take the analysis on an empty stomach; before donating blood from a vein, you should rest a little. It is good if before the study it is possible to exclude the use of alcohol, nicotine, and physical activity. It is necessary to tell the doctor what drugs were taken, as they can also affect the test results.
Any analysis or research gives the doctor additional information that helps to more accurately diagnose, determine the stage of the disease, and prescribe treatment. Blood test for heart function also helps to control the course of the disease, the effectiveness of the prescribed treatment, as well as to ensure the safety of the therapy. But sometimes more research is required to confirm or complement the results of past analyzes.
