The study compares two lengths of medication therapy (a shortened versus a prolonged dual
antiplatelet therapy) in order to prevent thrombus (blood cloth) formation after the
successfully treatment for coronary heart disease with a drug covered stent (metallic tube).
This comparison will be done in patients who, compared to the average patient, are more
likely to suffer from complications on antiplatelet therapy (bleeding). Both durations are
within the current medical recommendations. The aim of this study is to help improve further
standard antiplatelet duration guidelines.
