Summary

The procedure, known as distal microcirculatory protection, does not necessarily hurt a patient, the researcher's note, but it also does not have any benefit. Doctors perform the procedure, almost routinely, as part of angioplasty and other open-heart surgeries.

"It's not entirely clear why (the procedure) failed to improve patient outcomes, but it's possible that so much damage happens during a heart attack that (clearing the arteries) is applying too little, too late," said one of the study's leaders.

Details

• Interventional cardiologists from Columbia University Medical Center have shown that a commonly used procedure to remove fatty debris from blocked arteries during a heart attack does not improve patient outcomes.
• The procedure, called distal microcirculatory protection, is commonly and successfully used during angioplasty in vein grafts and stenting in carotid arteries.
• The study, published in the March 2 issue of the Journal of the American Medical Association, found that the devices were successful in removing debris from the arteries in angioplasties during heart attacks, but it showed that there was no benefit to the patient.
• The study, which was conducted in 38 institutions in seven countries, examined 501 patients who were having heart attacks, half of whom received distal protection.
• The study evaluated the efficacy of distal protection devices using several measures, including evaluating patient ST segments -- a portion of the EKG that can indicate heart damage when it is elevated.
• The study showed that the percentage of patients who had normalization of the ST segment were the same, whether or not distal protection devices were used.
• Within six months of the heart attack, patients had a comparable frequency of major adverse cardiac events regardless of whether or not they received the treatment.
• The study also measured the size of the heart attacks by measuring the uptake of a tracer in the heart, and found that there was no difference for patients who received distal protection.
• According to Dr. Stone, not using distal protection devices will reduce the cost of angioplasties during heart attacks, and could avoid potential complications caused by the devices.
