New fast test for infarct detection successfully tested

What can the 1-hour tropon test do?

Myocardial infarction is still the leading cause of death in Germany. About 49,000 people die each year in this country. 220,000 sufferers are treated each year in German hospitals because of a heart attack. In addition, there are a large number of unreported cases because not all heart attack patients know they had an infarction. On the other hand, other patients mistakenly believe that they have an infarction without being the case. The symptoms are not always clear. A new quick test is now to ensure a faster and safer treatment for heart attacks.

With German Heart Fund, the German Foundation for Heart Research (DSHF) successfully supported a new rapid test method called a 1-hour troponin test for diagnosing a heart attack in 1,500 high-risk patients. The test detects within an hour whether a heart attack is present or not. This is crucial for the further treatment of those concerned.

A heart attack can have many faces

As heart experts from the German Heart Foundation report, a heart attack can manifest itself in different ways. Many suffer complaints of burning and repressive chest pain associated with a sense of tightness. Others describe their symptoms as radiating pain that runs from the sternum of the arms, shoulder blades, neck, jaw and abdomen. In addition, simultaneous symptoms such as excessive sweating, nausea and shortness of breath may occur. Some patients also show less obvious signs.


Many symptoms associated with a heart attack may also indicate other diseases. "The faster and safer the existing disease can be diagnosed, the faster the appropriate treatment can take place and the greater the chances of cure for the patients," Professor Dr. Senior explains. with. with. Willibald Hochholzer in a press release on the new diagnostic method. So far, doctors have primarily used an electrocardiogram to analyze cardiac currents. However, this is not the key criterion for supporting a heart attack diagnosis.

A protein complex indicates heart damage

The heart specialists explain that one can only make a reliable diagnosis using the so-called troponin. It is a protein complex that helps the heart muscle cells to contract, ensuring that the heart performs its role as a blood pump. If these muscle cells receive too little oxygen due to infarction, troponin is released into the blood. According to the German heart foundation, this also occurs in other diseases where the heart is damaged, such as in a pulmonary embolism, a septic shock or certain cardiac arrhythmias. "These patients, due to a relative acid deficiency, also undergo a type of" infarction "without vascular occlusion, a type 2 myocardial infarction," Professor Hochholzer explains.

Each infarct requires the right treatment

After the underlying cause decides the right treatment. When talking about a heart attack, type 1 myocardial infarction is primarily intended. This should normally be treated as soon as possible by immediately re-opening the affected coronary artery with a balloon and implanting a stent. "The test works perfectly well to exclude a heart attack, even in high-risk patients", the professor summarizes the test results.

How does a 1-hour troponin test work?

The test measures the presence of troponin in the blood. The so-called 1-hour Troponin Diagnostic Algorithm recognizes within an hour whether or not a heart attack actually exists. The new test is recommended in the current guidelines of the European Society of Cardiology (ESC) for patients with a suspected heart attack. Currently, the test must be improved in such a way that it can also differentiate a type I myocardial infarction from a type 2 myocardial infarction. (Vb)
