Blood screening to assess future risk of heart disease:

Researchers believe that a regular blood test already to detect the sudden onset of a heart attack in the emergency room, along with a statin prescription, can help in reducing the future risk of having a heart attack in patients who have no apparent signs.

Some people are most likely to suffer from a heart attack, also known as myocardial infarction. It is generally because of their lifestyle-related risk factors. Obese people, with a diet too rich in saturated fats, diabetics, sedentary, smokers are particularly the most concerned.

But this necrosis of a more or less significant part of the heart muscle can also affect patients who are not part of these populations. Tests such as measuring blood pressure or cholesterol levels help in determining this risk. But researchers wish to favor another screening method that claims to be more effective in identifying the people concerned: a simple blood test.

The latter can diagnose the future risk of a heart attack based on the level of troponin in the blood, a protein that enters into the constitution of muscle fibers and plays a role in their contraction. The troponin test is a blood test already performed in the emergency room when patients complain of chest pain. Its rate is high when the heart cells die.

Establish a diagnosis as soon as possible:

This examination can make it possible to rule out the immediate occurrence of myocardial infarction in favor of other cardiac pathologies. So it is vital to carry out a thorough blood test diagnosis as soon as possible to avoid any kind of severe consequences.

Blood tests:

What is it about?

The determination of diseases of the heart or vessels often goes through blood tests. Many cardiovascular diseases cause changes in the metabolism that a blood test can detect. For example, during myocardial infarction, there is an increase in the concentration of Troponin, a regulatory protein, as well as the creatine kinase enzyme (Ck-MB); in case of heart failure, the “Brain Natriuretic Peptide” (BNP) level increases.

Process of a blood test:

Blood is drawn from the patient, who is then examined in the laboratory.

Duration of a blood test:

Many blood tests are done so quickly that in an emergency, you can get results after just a few minutes. At the doctor’s office, some blood tests must be sent to the laboratory, so it takes longer to get the final results.

A single early blood test to identify the risk of a heart attack?

A patient arrives in the ER with chest pain. How do you know if he has a low or high risk of having a heart attack within hours? According to a recent study, a single early blood test would be enough to assess this risk. And, therefore, to better care for patients.

When an infarction is getting ready, there is a large amount of troponin in the blood. With a high sensitivity blood test, you can detect minimal amounts of troponin so that you can make a confirmation about the presence of any kind of heart disease.
