CHD 005.1 Rationale

Both NICE (2007/2011) and Scottish Intercollegiate Guidelines Network (SIGN) (2007) clinical guidelines recommend that aspirin (75150 mg per day) should be given routinely and continued for life in all patients with CHD unless there is a contraindication. Clopidogrel (75 mg/day) is an effective alternative in patients with contraindications to aspirin, or who are intolerant of aspirin.

NICE clinical guideline CG172. Secondary prevention in primary and secondary care for patients following MI 2013
NICE clinical guideline CG126. Management of stable angina 2011.
SIGN clinical guideline 96. Management of stable angina 2007. Grade A recommendation. www.sign.ac.uk/guidelines/fulltext/96/index.html
SIGN clinical guideline 97. Risk estimation and the prevention of CVD 2007. Grade A recommendation. www.sign.ac.uk/guidelines/fulltext/97/index.html
