Half of all heart attack patients may not be receiving a recommended, potentially life-saving dose of aspirin on their way to the hospital. Using emergency medical services (EMS) information collected nationwide, University of Chicago Medicine researchers focused on ambulance runs involving people age 40 or older who were being monitored for suspected heart attacks. Paramedics had recorded giving aspirin to only 45.4 percent of these patients.
In the August 31 issue of Science Translational Medicine, new research from the University of Chicago shows how deficits in a specific pathway of genes can lead to the development of atrial fibrillation, a common irregular heartbeat, which poses a significant health risk. Researchers describe a complex system of checks and balances and offer insights that could lead to individualized treatment in humans.
