(CNN) Fewer heart attack and stroke patients are arriving at hospital emergency departments and doctors still aren't sure why. The American Heart Association continues to urge people to call 911 if they experience any chest pain or heart symptoms. In April, the group and other medical organizations put out an urgent statement telling the public not hesitate to go to the hospital or call 911 in case of a medical emergency, even amid the coronavirus pandemic. "We know conclusively that every moment delay in getting the right treatment for a heart attack or the right treatment of a stroke results in less heart muscle and less brain," Dr. Mariell Jessup, chief science and medical officer of the American Heart Association, told CNN on Wednesday. "Studies have shown the faster you can open up the artery that supplies the brain with blood, or the heart with blood, the better chance you have of preserving your heart function and your brain function."
