Ischemic events were more common than bleeding events in patients surviving 1 y after coronary stenting via percutaneous coronary intervention (PCI), but both were associated with significantly higher mortality.
Why this matters
Little was known about the prognosis for late ischemic and bleeding events after PCI.
Secondary analysis of Dual Antiplatelet Therapy Study.
11,648 patients underwent PCI, received thienopyridine + aspirin for 12 mo, then randomized to continue thienopyridine or placebo for 18 mo.
Funding: Harvard Clinical Research Institute, National Institutes of Health, and others.
At 21 mo, overall ischemic event rate 4.1% (59.2% were in placebo group, 40.8% in treatment group); 10.9% died.
