Right now, doctors have two common ways to tell you if you have had a heart attack: An EKG or a blood test.
The problem is an EKG is not always accurate and a blood test takes too long.
The only thing Elton Cain remembers about being rushed to the hospital was the tightness in his chest.
But Dr. Kevin Wei remembers it well.
He was called to the ER to determine if Elton was having a heart attack.
Elton's EKG was inconclusive, so Dr. Wei used something new; an ultrasound picture enhanced with micro bubbles.
The tiny bubbles are injected into the bloodstream and travel to the heart muscle.
Dr. Wei, of the Oregan Health & Science University stated, "We can see very clearly this horseshoe shaped area, which is the heart muscle and how one area is not contracting."
Elton was indeed having a heart attack.
Doctors immediately started him on medication.
If they had waited for his blood test to come back, treatment would have been delayed by seven hours.
Right now, only a few centers across the country are using the new micro bubbles technique.
