When to use
- After 12 months of event-free DAPT post-PCI, to decide on extending therapy.
Formula
Age >=75:-2, 65-74:-1; smoking 1; diabetes 1; MI at presentation 1; prior PCI/MI 1; stent <3 mm 1; paclitaxel stent 1; CHF or EF <30% 2; vein graft PCI 2. Range -2 to 10.
Pearls and pitfalls
- Higher scores favour ischaemic benefit outweighing bleeding harm from continued DAPT.
- Applies only to patients already tolerant of 12 months of DAPT without event.
