To keep up with his grandson Jason, 71-year-old John Misfud has to keep fit. When he noticed he was short of breath, Misfud didn't waste any time getting to his doctor. He was the first person in the United States to have a LipiScan. It detects cholesterol-filled arteries before a heart attack happens.
"These catastrophic events most often come from plaques that, prior to the heart attack, were not all that narrowed … and never would have showed up on a stress test," James Goldstein, M.D., an interventional cardiologist at Beaumont Hospital in Royal Oak, Mich., told Ivanhoe.
Standard testing uses an angiogram. It can identify narrowing vessels but cannot identify fatty plaques. Dr. Goldstein says the LipiScan gives him a more detailed map of the blood vessels.
"[It's] like if you took the blood vessel and slit it open and laid it on a plate … it detects the presence of cholesterol-laden plaques," Dr. Goldstein said.
A catheter tipped with a fiber-optic laser is threaded to the artery. It shines infrared light through the blood to the artery wall and measures the light reflected back. The reflected wavelengths are measured by a chemogram, revealing how much fat is in the plaque.
Because of what doctors found in his scan, they changed the course of treatment for Misfud.
"It showed us those adjacent areas that were filled with cholesterol-laden plaque, so the decision was to, instead of using a short stent, use a longer stent," Dr. Goldstein said.
John was home from the hospital in a day -- and within weeks, back to horsing around.
"I'm no spring chicken, but I feel good!" Misfud said.
Based on further research, this scan may help determine which type of stent -- bare metal or drug-eluting -- is best for a patient.

Coal miners provide the raw material for nearly half of America's power. Mining is a necessity, but it's a dangerous job. Every year, 40 people in the United States die trapped in a mine, and China alone reported almost 4,000 coal mining deaths in 2007.
