In a recent study, researchers found that less than a quarter of emergency
room patients with chest pain, a symptom of heart attack, used emergency
medical transportation, with some even driving themselves to the hospital.
Among people who first called their doctors, emergency medical service use
was lower, which worries researchers who think these people may be lulled into
a false sense of security.
The benefits of using emergency medical services is that treatment begins
upon arrival and the emergency department can be notified in advance, so care
on arrival to the hospital can be quicker.
