Spinning sessions trigger the same biochemical indications as heart attacks

07.02.2012
A short spinning session can trigger the same biochemical indications as a heart attack – a reaction that is probably both natural and harmless, but should be borne in mind when people seek emergency treatment for chest pain, reveals a study from the Sahlgrenska Academy at the University of Gothenburg, Sweden.
Heart attacks increase the secretion of enzymes known as cardiac biomarkers, which can be measured using a simple blood test. This is important for rapid diagnosis and initiation of treatment. However, levels of these biomarkers also increase in situations that have nothing to do with heart disease, such as long periods of strenuous physical exertion like marathons, triathlons or long skiing races.

Important for accurate assessment
Researchers at the University of Gothenburg’s Sahlgrenska Academy have now investigated whether shorter and less intensive forms of exercise have the same effect on cardiac biomarkers. This information is important for the accurate assessment of patients seeking emergency medical treatment after exercise.

Heart attack levels
The study included ten healthy people, with an average age of 30, who took part in an hour-long spinning session where researchers measured cardiac biomarkers in the blood immediately before the session as well as one hour after and again 24 hours after. The study showed that levels of a commonly used cardiac biomarker, the heart enzyme troponin T, doubled an hour after the session. In two of the individuals the enzyme rose to levels that are routinely used as the threshold for heart attacks.

Normal in 24 hours
“Levels returned to normal in everyone in the study 24 hours after the spinning session,” says Smita Duttaroy, researcher at the Sahlgrenska Academy. “This is an important difference to patients who’ve had a heart attack, where levels of the markers can remain raised for several days afterwards.”

More awarness needed
The exercise-induced increase in cardiac biomarkers in healthy people is probably not dangerous but is, instead, a normal bodily reaction to exercise. However, Duttaroy feels that the similarities with heart attacks mean that emergency treatment teams must be more aware.
“When somebody with chest pains comes for emergency treatment, and a blood test shows that the cardiac biomarkers are rising, it’s important to recognise that this kind of increase can also occur in healthy people after a normal exercise session.”

Passing the knowledge
Duttaroy and her research colleague Mats Börjesson, who were responsible for the study, now hope to be able to pass this knowledge on to colleagues who work with patients with chest pains.
The study “A single-bout of one-hour spinning exercise increases troponin T in healthy subjects” has been published in the Scandinavian Cardiovascular Journal.

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
