But, Shaw pointed out, the patients included in this study all had relatively good blood flow overall and were considered low risk for cardiac problems. "It remains to be seen [how the strategies fare] in patients with more extensive and moderate to severe ischemia," Shaw said.
Another trial is now being planned which will look at patients with moderate-to-severe ischemia.
Because this study was presented at a medical meeting, its data and conclusions should be viewed as preliminary until published in a peer-reviewed journal.
And one expert not involved in the trial said that the jury is still out on this issue.
Dr. Jeffrey S. Borer, chair of the department of medicine and of cardiovascular medicine at the State University of New York (SUNY) Downstate Medical Center in New York City, noted that the length of time patients were tracked in the study was not very long.
"This study is useful and the data is interesting . . . [but] what we really care about is longer term clinical results," he said.
