Prasugrel, a novel anti-platelet therapy, is used to prevent recurrent cardiovascular events in patients who have had a prior heart attack, suffer severe chest pain and have been treated with coronary artery procedures (revascularization).
Recent results from a large clinical trial, the TRILOGY ACS study that focused on the effectiveness and safety of prasugrel in high-risk patients with acute coronary syndrome (ACS) who are medically managed without revascularization, found a neutral effect (failed to show a reduction in major cardiovascular events compared with clopidogrel).
However, in a new analysis, researchers from Brigham and Women's Hospital (BWH) examined whether prasugrel would benefit a subset of patients with acute coronary syndrome (ACS), a condition categorized by sudden, reduced blood flow to the heart, who underwent angiography (visualization of the coronary arteries), but did not have a percutaneous coronary intervention (PCI), prior to being randomized to receive either prasugrel or clopidogrel.
Stephen D. Wiviott, MD, senior investigator with the TIMI Study Group, associate physician, Cardiovascular Division at BWH, and associate professor of Medicine at Harvard Medical School presented the data at the Transcatheter Cardiovascular Therapeutics 2012 meeting in Miami, FL on October 24, 2012 with Deepak L. Bhatt, MD, MPH, Chief of Cardiology at VA Boston Healthcare System, a senior physician in the Cardiovascular Division at BWH and professor of Medicine at Harvard Medical School.
"Despite the neutral findings of the TRILOGY study, it may be possible to identify a subset of medically managed patients who benefit from more intensive platelet blockade," said Dr. Wiviott. "What we found was that there may be a distinct patient population among those who do not receive a PCI, who could be successfully managed with this therapy, however to prove this, additional study would be required."
