An analysis of patient data captured in the NCDR-STS-CMS databases and presented at the American College of Cardiology annual meeting favored bypass surgery over angioplasty at four years. Physicians point out that the study overlooked important factors in the analysis. "A major flaw in ASCERT was that it compared apples to oranges. It looked at a specific subset of very sick, older patients, and it did not take into account a variety of factors that could have affected these data," said SCAI President Dr. Christopher White in a statement. "PCI is not only a safe and effective treatment option for patients, it often is the only treatment available to patients too sick or too frail to have open heart surgery."
