When not to treat..and what not to do… Western Stroke Day Nov, 30, 2012 Negar Asdaghi MD FRCPC
MrPS • 81 year old, RHD retired family doctor • Presented with sudden onset of left sided weakness within 2.5hr of onset
PMH • HTN • DM • Dyslipidemia • CAD (stent 2001) • Atrial fibrillation (not currently on OAC) • Previous history of ICH (2001 AAICH (INR=8.9), 2008 spontaneous IVH) • CRF
Rx Med: ASA 81 mg/daily Ramipril 5mg/daily Diltiazem180 mg/daily Simvastatin 40 mg/daily Metformin 500/BID
HPI Continued.. • Developed sudden onset of left sided weakness (F/A/L) associated with some confusion • No history of trauma, no seizure like activity
Exam • SBP=165-170, HR= irregular, 100-120 • Dense gaze preference to the right • left HHA • left sided neglect • left UMN facial weakness • Left arm and leg 0/5 • Upgoing plantar response on the left • NIHSS=21
What to do..? • 2.5 hrs into a large acute Rt MCA stroke • Prior history of ICH • No other contraindications • 12:30 a.m.
Exclusion Criteria for tpa Adams et al. Guidelines for the early management of adults with ischemic stroke: a guideline from the American Heart Association/American Stroke Association Stroke Council, Clinical Cardiology Council, Cardiovascular Radiology and Intervention Council, and the Atherosclerotic Peripheral Vascular Disease and Quality of Care Outcomes in Research Interdisciplinary, 2007
5594 IV-tpa treated patients, 34.3% off label use 422 IV-tpa treated patients, 55% off label use
1105 patients were thrombolyzed • 51% of thrombolytic cases were off label • 33% had two concomitant contraindications • 3% had 3 concomitant contraindications • 3 patients had prior ICH, SAH • The only independent factor associated with poor outcome was age>80
Commonest reasons for of off-label use of tpa: • Age>80 • Minor stroke (NIHSS<5) • Late treatment >3hr • BP>185/110 • Anti-coagulation
Canadian data on off label use of tPA Treat fist ask questions later
Treatment • IV tpa started • Angio suite staff on route • Patient started moving his left arm within 20 min of infusion • By the time of puncture the only deficits were left HHA and some minor drift
Course in the hospital • NIHSS at 24 hours was 2 • No bleeding
Discharge • Doing well • CrCl ≈30 • Decision to start Anti-coagulation?
