According to two studies, blood tests ultra-sensitive new can quickly detect when the heart muscle to die of a heart attack, even from the time the patient arrived at the emergency room. Two of the tests made by Roche AG, one by Siemens AG and one made by Abbott. All four new test is Architect troponin I (Abbott), High-Sensitive troponin T (Roche), troponin I (Roche) and troponin I Ultra (Siemens).

With older tests, it could be a sign bebrapa hours before cardiac troponin levels appear in the blood chemistry, delaying diagnosis and treatment. But the study found that this new test to work faster and more accurate.



Around 15 million people show up in emergency rooms in the U.S. and Europe each year with symptoms of heart attack, also known as myocardial infarction.

Quick test can save time, billions of dollars and many lives by speeding up treatment or to help physicians quickly determine whether a heart attack do not cause symptoms in patients.

Dr Tobias Reichlin from the University Hospital Basel in Switzerland, and colleagues write in one of two reports published in the New England Journal of Medicine that the cost savings associated with an increased initial diagnostic accuracy may be very large.

Electrocardiogram, which measures electrical activity of the heart, and cardiac troponin tests, which seek the release of proteins unique to the heart, is the best way to measure a heart attack. But this can take several hours for troponin to enter into the blood at levels high enough to be measured.

New studies, both conducted in Europe, designed to see whether the new generation troponin detector sensitive enough to be used more quickly.

Reichlin group studied 718 patients and found that the four ultrasensitif troponin detection devices, better than the Roche test equipment on the 123 older people who really suffer a heart attack.

Very High Accuracy

All four tests to determine the exact heart attacks in at least 94 percent of cases, compared with standard tests are accurate Roche 90 percent of the time. The researchers concluded that this test can substantially improve the early diagnosis of acute myocardial infarction, especially in patients with chest pain onset.



The second study, conducted at three medical centers of Germany, Siemens test study and found comparable results. Siemens parties not involved in this test. But the team, led by Dr. Keller Till from Johannes Gutenberg University in Mainz, cautioned that other research is needed to see whether the diagnosis was quickly translated into better outcomes for heart attack patients.
