Abstract

Background and purpose: It remains uncertain whether current smoking influences outcome in patients with acute ischaemic stroke.

Objectives: To evaluate the effect of current smoking in routinely tissue plasminogen activator (tPA)-treated stroke patients on the 3-month functional outcome and the occurrence of symptomatic intracerebral hemorrhage (ICH).

Methods: We analyzed data from a single stroke care unit registry of 345 consecutive patients with ischaemic stroke, treated with tPA. Logistic regression models were used to assess if smoking was independently associated with 3-months good outcome defined as a modified Rankin Scale score of < or =2, and the occurrence of symptomatic ICH.

Results: In the multivariable models, smoking was not associated with a good outcome or a decreased risk of symptomatic ICH.

Conclusion: Current smoking did not affect functional outcome at 3 months or the risk of symptomatic ICH in patients routinely treated with tPA for ischaemic stroke.
