DAPT recommendation

Current recommendation for DAPT duration is

Current recommendation for DAPT duration
Stable ischemic heart disease6 months
Acute coronary syndrome12 months
DAPT recommendation
  • Stable ischemic heart disease – 6 months
  • Acute coronary syndrome (ACS) – 12 months

Current medical guidelines recommend a 6-month duration of DAPT for stable coronary disease and 12 months for acute coronary syndrome (ACS).


High bleeding risk

For patients at high bleeding risk, 1–3 months of DAPT may be better than 12 months to reduce the risk of major bleeding.

High ischemic risk

For patients at high ischemic risk, longer-duration DAPT may be reasonable.

Non-ACS

For patients with non-ACS, 1–3 months of DAPT is recommended for patients at high bleeding risk.


After PCI in patients presenting with chronic coronary syndrome, DAPT duration of 6 months is recommended. However, shortening to at least 1 month or extension up to ≥12 months is also supported by the guidelines in dependence of ischemic and bleeding risk.
