Study shows stroke prevention clinics reduce 1-year mortality rates by over 25 percent
Research led by Dr. Vladimir Hachinski of The University of Western Ontario reveals just how important it is for patients to be referred to a stroke prevention clinic following either a mild stroke or a transient ischemic attack (TIA).
The study, published in the journal Stroke in November, showed a 26% reduction in one-year mortality rates among those referred to a stroke prevention clinic.
The risk of stroke after a TIA may be as high as 20% in the first three months. Half of the strokes occur in the first 24 to 48 hours after a TIA. Organized inpatient care has been shown to decrease morbidity and mortality but little research has been done on the benefits of organized outpatient stroke prevention clinics. These clinics facilitate early assessment, diagnosis and treatment of patients with a recent TIA or non-disabling stroke.
Using data from the Registry of the Canadian Stroke Network, the researchers compared more than 16,000 patients with ischemic stroke or TIA seen in the emergency department or admitted to hospital in Ontario between July 1, 2003 and March 31, 2008.
"Organized stroke care works," says Dr. Hachinski, a Professor in the Department of Clinical Neurological Sciences at Western's Schulich School of Medicine & Dentistry, and a Scientist with the Lawson Health Research Institute. "It doesn't really matter about the size, location and hours of these clinics. Patients benefit because you have interested people with some expertise, following best practice standards and gaining experience from doing things repeatedly."
"This study provides important evidence that referral to a SPC reduces mortality. The basic underlying principle of our study is that organized care, even with staggered models, makes a positive difference at all levels," adds Fiona Webster, first author and Education Scientist/Assistant Professor in the Department of Family and Community Medicine at the University of Toronto.
Funding for the study was provided by the Canadian Institutes of Health Research, the Ontario Ministry of Health and Long-Term Care and the Canadian Stroke Network.

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.
The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...
New technique promises tunable laser devices
Whispering gallery mode (WGM) resonators are used to make tiny micro-lasers, sensors, switches, routers and other devices. These tiny structures rely on a...
Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
