Overview
Cardiac & Stroke Emergency Care
In those critical moments that count the most, Overlake's Emergency Room provides rapid access to leading-edge cardiac and stroke care.
Quick Intervention Saves Lives

On July 19, 2010, Mark Hornberger came home from work, sat down to write an expense report and was jolted by chest pain. Even though Mark admits the pain was “like getting hit in the chest with a ball,” he dismissed the warning signs, as many heart attack victims do. “I thought it would go away — I just didn’t have time. I took a few aspirin.”
Mark, 53, was having a heart attack, and he later learned the delay could have cost him his life. He waited 30 minutes before calling a neighbor, who called 9-1-1.
Mark's blocked artery was opened just 22 minutes after he arrived at Overlake's ER.
Known regionally for our advanced cardiac care program, we have one of the longest track records in the country for providing primary angioplasty procedures for heart attack patients.
Door-to-Balloon
We are also known for the speed of our "door-to-balloon" time for heart attack patients. "Door-to-balloon" is the interval between a heart attack patient's arrival at the ER and the inflation of a balloon-tipped catheter to open a blocked artery. The national goal is under 90 minutes. However the team at Overlake has completed it in 22 minutes and typically gets the job done within 60 minutes.
Emergency vs. Urgent Care
The Emergency & Trauma Center at our main hospital campus in Bellevue and our 24-Hour Urgent Care Clinic in Issaquah were designed to serve very different needs, but they often work together to ensure patients receive the right level of treatment at the right time.
Emergency care should be used for matters of life or death or accidents or illnesses not treatable at your physician's office. Urgent Care specializes in treating illnesses and injuries that aren't life threatening but still require immediate attention. Review the chart on the right to learn more about when to visit the Emergency Department versus Urgent Care.
If you think you have a medical emergency, you should always call 9-1-1.
