Am Heart JPublished Meta-research study of clinical practice guidelines

Authors' conclusion

STEMI-related recommendations from foremost cardiology societies worldwide have largely relied on moderate/low-quality evidence, with slight changes over time.

Participants
2,139 participants
Comparison
PI vs NPI recommendations
Outcome
Classification of recommendations (CORs) and LOE of STEMI guideline recommendations over time
Follow-up

Main finding

As reported in the abstract

LOE of recommendations over the 33-year span

LOE-B (moderate quality) recommendations

30.1%

LOE-C (low quality) recommendations

28.9%

Recommendations based on high-quality evidence
