Combined therapy of intensive statin plus intravenous rt-PA in acute ischemic stroke: the INSPIRE randomized clinical...

To investigate the safety and efficacy of intensive statin in the acute phase of ischemic stroke after intravenous thrombolysis therapy.

A total of 310 stroke patients treated with rt-PA were randomly scheduled into the intensive statin group (rosuvastatin 20 mg daily × 14 days) and the control group (rosuvastatin 5 mg daily × 14 days). The primary clinical endpoint was excellent functional outcome (mRS ≤ 1) at 3 months, and the primary safety endpoint was symptomatic intracranial hemorrhage (sICH) in 90 days.

The intensive statin users did not achieve a favorable outcome in excellent functional outcome (mRS ≤ 1) at 3 months compared with controls (70.3% vs. 66.5%, p = 0.464). Intensive statin also not significantly improved the overall distribution of scores on the modified Rankin scale, as compared with controls (p = 0.82 by the Cochran-Mantel-Haenszel test). The incidence of primary safety endpoint events (sICH) in 90 days did not significantly differ between the intensive statin group and control group (0.6% vs. 1.3%, p > 0.999).

The INSPIRE study indicated that intensive statin therapy may not improve clinical outcomes compared with the low dose of statin therapy in AIS patients undergoing intravenous thrombolysis, and the two groups had similar safety profile.
