Fig. 1. Diagram showing study design. The reasons for exclusion are as follows : 1) Ten patients died within 14 days after ictus. 2) Two patients were transferred to pulmonary medicine due to lung diseases, thus had insufficient data about the occurrence of vasospasm. 3) Two patients had statin side effects. One patient (40 mg group) showed elevated liver transaminase up to 200 U/L. Another patient (80 mg group) complained muscle cramp of legs and creatine phosphokinase elevated to 1200 U/L. After cessation of statin, laboratory values were normalized within 3 days.
