ABSTRACT

Background and aims: Pre-hospital delay is a crucial factor that determines the eligibility for intravenous thrombolysis in patients with acute ischemic stroke. We aimed to evaluate the time to presentation at the emergency department (ED) and the factors that affect this time.

Patients and methods: We prospectively studied 682 patients who were admitted with acute ischemic stroke (43.3% men, age 79.9 ± 6.6 years).

Results: The median time to presentation at the ED was 2.1 h (range 0.15 to 168 h); 68.8% of the patients arrived within 4.5 h and 56.5% arrived within 3 h from the onset of symptoms. Independent predictors of presentation within 4.5 h were the use of emergency medical services (EMS) for transportation to the hospital (OR 2.61, 95% CI 1.38–4.94, p = .003), family history of cardiovascular disease (CVD)(OR 4.0 0,95%CI 1.61–12.23, p = .006) and the absence of history of smoking (OR 2.49, 95% CI 1.13–5.42, p = .021). Independent predictors of presentation within 3 h were the use of EMS for transportation to the hospital (OR 6.24, 95% CI 2.52–16.63, p = .0001), family history of CVD (OR 3.07, 95% CI 1.14–9.43, p = .03), and a moderately severe stroke at admission (OR vs. minor stroke 0.38, 95% CI 0.16–0.87, p = .02).

Conclusions: A considerable proportion of patients with acute ischemic stroke arrives at the ED after the 4.5-h threshold for performing intravenous thrombolysis. Non-smokers, patients with a family history of CVD, with moderately severe stroke and those who use the EMS are more likely to arrive on time.
