Surgery Timing After Coronary Stenting
Compares the interval since a coronary intervention against the published minimum delay before elective noncardiac surgery.

Example
- What was done
- Drug-eluting stent
- Days since the coronary intervention
- 120 days
Result: 120 days is past 90 but short of the 180-day optimum by 60
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Balloon, no stent
- Delay elective noncardiac surgery at least 14 days.
- Bare-metal stent
- Delay at least 30 days.
- Drug-eluting stent
- Optimally at least 6 months. After 3 months, surgery may be considered when the risk of further delay outweighs the risk of stent thrombosis.
- The three-to-six month window
- A judgment, not a green light. It is a shared decision with cardiology and surgery, and nothing in the number alone settles it.
- What the interval is about
- When to operate, not whether to stop the antiplatelet. Where surgery permits, aspirin is continued, and stopping both agents early is the exposure the interval exists to avoid.
- Urgent surgery
- Not delayed by any of this. These intervals govern elective procedures.
What you enter
- What was done
- Days since the coronary intervention
- The surgery is urgent or an emergency (these intervals do not govern it)
