Outcomes in coronary stent trials—1 year is not enough

The medical literature contains a huge number of studies on the safety and performance of novel stent platforms, with primary outcomes usually assessed at 6 months or 1 year. The 5-year analysis from SORT OUT III demonstrates that, when assessing clinical outcomes in stent trials, 1-year follow-up is not enough.
