Intracranial haemorrhage following tenecteplase fibrinolysis for acute myocardial infarction

Eur Heart JPublished

  • Pooled individual patient data analysis of six randomised controlled trials
  • logistic regression
  • nomogram for individual risk prediction

Authors' conclusion

Dose reduction of TNK in older patients and SBP optimization before fibrinolytic administration represent modifiable strategies to potentially reduce ICH.

Study context

Population
ST-elevation myocardial infarction (STEMI) patients given weight-adjusted TNK (BP exclusion >180/110 mmHg) in ASSENT-2, ASSENT-3, ASSENT-3 PLUS, ASSENT-4 PCI, STREAM, STREAM-2
Participants
15,954 participants · 6 RCTs
Outcome
Risk factors for ICH after TNK; clinical risk prediction tool
