摘要：

Objective To study the time dependent effectiveness of thrombolytic therapy for acute ischaemic stroke in daily clinical practice. Design A retrospective cohort study using data from a large scale, comprehensive population based state-wide stroke registry in Germany. Setting All 148 hospitals involved in acute stroke care in a large state in southwest Germany with 10.4 million inhabitants. Participants Data from 84 439 patients with acute ischaemic stroke were analysed, 10 263 (12%) were treated with thrombolytic therapy and 74 176 (88%) were not treated. Main outcome measures Primary endpoint was the dichotomised score on a modified Rankin scale at discharge ("favourable outcome" score 0 or 1 or "unfavourable outcome" score 2-6) analysed by binary logistic regression. Patients treated with recombinant tissue plasminogen activator (rtPA) were categorised according to time from onset of stroke to treatment. Analogous analyses were conducted for the association between rtPA treatment of stroke and in-hospital mortality. As a co-primary endpoint the chance of a lower modified Rankin scale score at discharge was analysed by ordinal logistic regression analysis (shift analysis). Results After adjustment for characteristics of patients, hospitals, and treatment, rtPA was associated with better outcome in a time dependent pattern. The number needed to treat ranged from 4.5 (within first 1.5 hours after onset; odds ratio 2.49) to 18.0 (up to 4.5 hours; odds ratio 1.26), while mortality did not vary up to 4.5 hours. Patients treated with rtPA beyond 4.5 hours (including mismatch based approaches) showed a significantly better outcome only in dichotomised analysis (odds ratio 1.25, 95% confidence interval 1.01 to 1.55) but the mortality risk was higher (1.45, 1.08 to 1.92). Conclusion The effectiveness of thrombolytic therapy in daily clinical practice might be comparable with the effectiveness shown in randomised clinical trials and pooled analysis. Early treatment was associated with favourable outcome in daily clinical practice, which underlines the importance of speeding up the process for thrombolytic therapy in hospital and before admission to achieve shorter time from door to needle and from onset to treatment for thrombolytic therapy.
