There’s never been a better time to be
treated for a heart attack. U.S. hospitals have set a record for how
quickly they open blocked arteries, averaging under one hour for the
first time since these results have been tracked.
More than 93 percent of patients now have their arteries opened within
the recommended 90 minutes of arrival.
“Things have definitely improved” from a decade ago, when less than half
of heart attack patients were treated that fast, said Dr. Fred Masoudi,
a University of Colorado cardiologist who led a recent report examining
response times.
It’s based on records from about 85 percent of U.S. hospitals that do
the artery procedure, angioplasty . Through a blood vessel in the groin
or an arm, doctors guide a tube to the blockage causing the heart
attack. They inflate a tiny balloon to flatten the clog, and leave
behind a mesh tube called a stent to prop the artery open.
The sooner blood flow is restored, the less chance of permanent damage.
“It’s one of the few things in medicine where time, literally seconds,
is of the essence. It’s where the phrase ‘time is muscle’ comes from,”
said Dr. Ajay Kirtane, director of the lab that performs angioplasties
at New York-Presbyterian/Columbia University Medical Center.
The risk of dying goes up 42 percent if care is delayed even half an
hour beyond the 90 minutes that U.S. guidelines say patients should be
treated after arrival.
In 2005, this “door-to-balloon” time averaged a dismal 96 minutes, and
the American College of Cardiology led a drive to get hospitals to
improve. The report shows it plunged to 59 minutes in 2014.
It was only 24 minutes for George Smith at UConn John Dempsey Hospital
in Farmington, Connecticut. The 82-year-old woke up on March 31 with
intense jaw pain, the same kind he had during a heart attack two years
ago. His wife called 911. An ambulance whisked him to the emergency
room, and “they were all waiting for me” at the door, he said.
An hour later he was sitting up in bed with a new stent. “I was amazed,”
he said. “Such a blessing.”
One reason UConn is so fast — its median door-to-balloon time was 56
minutes last year, and only 39 minutes during one recent quarter — is
the work it has done to make its emergency responders part of the
cardiac care team, said the hospital’s EMS coordinator, Peter Canning.
“We used our paramedics to extend our hospital into the patient’s home,”
where they do an extensive electrocardiogram of the heartbeat and call
results ahead to the hospital to get the angioplasty room ready, he
said. “Calling from 25 minutes out instead of 5 minutes out can be a
savings of 20 minutes of heart muscle.”
But all that speed by the hospital won’t do much good unless patients
act fast, too, and call 911 if they think they might be having a heart
attack.
