Monitoring Pulse After Stroke May Prevent a Second Stroke

24.07.2014

New research suggests that regularly monitoring your pulse after a stroke or the pulse of a loved one who has experienced a stroke may be a simple and effective first step in detecting irregular heartbeat, a major cause of having a second stroke. The study is published in the July 23, 2014, online issue of Neurology®, the medical journal of the American Academy of Neurology.

“Screening pulse is the method of choice for checking for irregular heartbeat for people over age 65 who have never had a stroke. Our study shows it may be a safe, effective, noninvasive and easy way to identify people who might need more thorough monitoring to prevent a second stroke,” said study author Bernd Kallmünzer, MD, with Erlangen University in Erlangen, Germany. 

For the study, 256 people who had experienced a type of stroke called an acute ischemic stroke and the patients´ relatives were given instructions on measuring the pulse to detect irregular heartbeat, one type of which is called atrial fibrillation. The measurements taken from the participants and health care professionals were then compared to a recording of electrical activity in the heart, which showed that 57 of the participants had irregular heartbeats. 

The study found that pulse measurement taken by health care professionals had a sensitivity of nearly 97 percent and a specificity of 94 percent in detecting irregular heartbeats. Sensitivity is the percentage of actual positives that are correctly identified as positive, and specificity is the percentage of negatives that are correctly identified. For patients’ relatives, the sensitivity was 77 percent and the specificity was 93 percent. 

For patients taking their own measurements, 89 percent performed reliable measurements with a sensitivity of 54 percent and specificity of 96 percent. False positive results occurred in six people and false negative results in 17 people. 

“The low rate of false positives in this study shows that health care professionals, caregivers and patients can be guided to use this simple tool as a first step in helping to prevent a second stroke,” said Kallmünzer.

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
