Abstract TMP5: The Smoking-Thrombolysis Paradox in Large Vessel Occlusion Acute Ischemic Stroke Undergoing Endovascular Therapy

Background and Purpose: The smoking-thrombolysis paradox has been well described in myocardial infarction. However, its existence in the stroke population remains elusive. In the past decade, several studies have investigated the phenomenon with mixed results. We sought to determine whether clinical outcomes differ between smokers and non-smokers with acute ischemic stroke undergoing endovascular therapy. Methods: We reviewed our prospectively collected endovascular database at a tertiary care academic institution. All patients who underwent endovascular therapy for acute large vessel occlusion acute ischemic stroke were categorized into current smokers and non-smokers. Baseline characteristics, procedural radiological as well as outcome parameters where compared. Results: A total of 968 patients qualified for the study of which 189 (19.5%) were current smokers. Smokers were younger (60.78±11.95 vs. 66.41±15.05 years, p<0.001), had higher rates of dyslipidemia (49.7% vs 31.7%, p<0.001) and posterior circu...
