Better treatment of atrial fibrillation and its risks

16.08.2010
The earlier that patients who suffer from atrial fibrillation obtain the correct treatment, the lower is the risk of serious secondary effects such as stroke. A thesis presented at the University of Gothenburg, Sweden, shows that a well-established measurement score can easily assess the risks for this patient group.

The function of the heart is affected if it is subject to atrial fibrillation for a long period. It becomes successively more difficult to restore and maintain the normal heart rhythm, and ever more difficult to treat. This can in turn lead to serious secondary effects for the patient.

Scientists have investigated how the score known as the CHADS2 score was correlated with the risk of being affected by stroke in patients with acute coronary syndromes and with or without atrial fibrillation. The CHADS2 score is used for the evaluation of stroke risk in patients with atrial fibrillation and it is based on the presence of Congestive heart failure, Hypertension (high blood pressure), Age of 75 years or older, Diabetes and previous Stroke.

Each above mention component gives one score, while stroke 2. According to guidelines, patients with score 2 or higher are candidates for permanent treatment with oral anticoagulation. A total of 2,335 patients with acute coronary syndromes, including myocardial infarction, were studied. Of these, 442 had atrial fibrillation.

"We found that the higher CHADS2 score was, the greater were the risk to be affected by stroke during long-term follow-up, and the risks of early (30-days) or long-term death. We also noticed in our investigation that this score was well applied and the results correlated even in patients with acute coronary syndromes and without atrial fibrillation. This means that the score, the CHADS2 score, may help to identify patients with high risk for subsequent stroke or death” says Dritan Poçi.

He believes that such a risk assessment should be made by the healthcare system for patients who have previously known atrial fibrillation, and for patients in whom it is discovered and newly diagnosed. This might be done independently of atrial fibrillation even in patients showing symptoms of myocardial infarction.

"It would increase the possibility of identifying and treating important risk factors. Such an individual treatment of these categories of patients may reduce the risk of subsequent diseases and increases the survival of patients", suggests Dritan Poçi.

ATRIAL FIBRILLATION
Atrial fibrillation is a common disturbance of heart rhythm that is found in approximately 2% of the population. It is expected that the incidence will double between now and 2050. In about 30% of cases, atrial fibrillation has unidentified reason. Hypertension and coronary artery disease (ischemic heart disease) are known to cause the condition.

Atrial fibrillation can be treated by drugs, invasive – ablation - procedures and surgery.

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: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

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.
