Heart attacks and strokes predictable in the future? – healing practice

Early risk prediction of cardiovascular diseases

A biomedical microdevice under development aims to changes in the blood identify which occur before it becomes one heart attack or a stroke comes. Such early prediction could help save millions of lives around the world every year.

In a recent study involving experts from University of Sydney a method has been devised to already minimal changes in blood platelets to identify which can lead to heart attacks and strokes.

The results of the research work can be read in the English-language journal “Analyst”.

Many deaths from cardiovascular disease

In Germany, according to the Robert Koch Institute (RKI) about 40 percent of all deaths associated with cardiovascular disease. Coronary heart disease is particularly common heart attacks and strokes.

Heart attacks and strokes often occur without warning

Heart attacks and strokes occur frequently up without a warningas they often through blood clot the researchers involved in the new study explain.

But a long time before a heart attack or stroke occurs, be already tiny changes in the blood detectable. For example, the blood flow is often disturbed, which leads to increased blood clotting and inflammation, which then causes the clog blood vessels be able.

The device only requires a blood sample

The newly developed micro device aims to subtle platelet changes identify before a heart attack or stroke even occurs. The device could use a simple pin prick test to do this blood sample taken from a person’s finger, the team reports.

Then the sample taken will be on the coagulation of the blood platelets and the inflammatory reactions of the white blood cells. This information could then be evaluated immediately by an external operating system.

Test people at risk every day

The device would work in such a way that a risk person, e.g. B. someone with a heart condition, uses it daily. Using a prick test, the device would monitor their blood and alert them to potentially dangerous changes‘ explains the author of the study Dr. Arnold Lining Ju of the University of Sydney in a recent press release.

If within such a test a critical change identified be, the persons concerned would have to further monitoring visit a hospitaladds the medic.

Better understanding of the causes of blood clots

It is our hope that this device will shed light on why and how blood clots form and that, if successful, it could one day be used in a range of healthcare scenarios“, emphasizes the author of the study Professor Shaun Jackson.

So far, it has been difficult to predict when a heart attack or stroke could occur. Thus, these diseases appear to occur randomly, which sometimes happens without physical symptoms, explains the study author Laura Moldovan.

In reality occur in such a case though smallest physical changes in the blood of the people affected and that the new device is able to do just that to monitor microscopic changes extremely closelyso Moldovan.

The next step is to artificial intelligence (AI) can be used to understand the blood count of individuals and such to create a personalized blood profile, reports the team. (as)
