Cardiac MRI shown to improve diagnosis in patients with life-threatening arrhythmias

15.02.2012
New research from Western University, Canada, has demonstrated the benefits of performing Cardiovascular Magnetic Resonance (CMR) in cases where patients have been resuscitated after Sudden Cardiac Death or enter hospital suffering from ventricular arrhythmias (abnormal heartbeat rhythm).

Cardiologist Dr. James White and his colleagues at Western's Schulich School of Medicine & Dentistry, found CMR is a highly effective diagnostic imaging tool, identifying a cardiac diagnosis in 75 per cent of cases compared with only 50 per cent in all other testing. Overall, CMR identified a new or alternate explanation for the arrhythmia in 50 per cent of patients. The findings are published in Circulation: Cardiovascular Imaging, a Journal of the American Heart Association.

The study tested the impact of performing CMR in 82 consecutive patients that presented to hospital with either resuscitated Sudden Cardiac Death or Ventricular Tachycardia. "In these cases, there is a fear of recurrence, so we want to identify what might be at the root of the heart rhythm," explains Dr. White, the Director of the Cardiovascular MRI Clinical Research Program at Schulich's Robarts Research Institute.

Standard cardiac imaging tests were conducted in all patients. But the researchers also used a 3-Tesla MRI at the Robarts Research Institute to evaluate whether they could find an answer with one test. "What we found was interesting. In three-quarters of the patients who had an MRI performed, we were able to identify a plausible reason why that heart rhythm occurred. When we looked at the conventional testing and in only half the patients found a cause. So this made a very big and incremental difference to our diagnosis of these patients. We also found that about 50 per cent of the time, we provided either a new or alternate diagnosis for this patient population." Often the patients were found to have inflammation of the heart muscle or small heart attacks that had gone undetected.

The research was conducted in conjunction with the arrhythmia department at London Health Sciences Centre (LHSC). Dr. White is a Cardiologist and a scientist with Robarts and the Biomedical Imaging Research Centre (BIRC) at Western and Lawson Health Research Institute. He is an assistant professor in the Department of Medicine at Schulich Medicine & Dentistry and practices within the Division of Cardiology at the LHSC.

Dr. White is supported by a Clinician Scientist Award from the Heart & Stroke Foundation of Ontario. Additional funding was supplied by the Canada Foundation for Innovation and the Ontario Research Fund.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
