Japan Statin Treatment Against Recurrent Stroke | Clinical Trial - J-STARS
The goal of the trial was to evaluate treatment with low-dose pravastatin compared with placebo among Japanese patients with prior ischemic stroke.
Contribution to the Literature: The J-STARS trial failed to show a reduction in recurrent cerebrovascular events with low-dose pravastatin.
Patients with prior ischemic stroke were randomized to pravastatin 10 mg (n = 793) versus control (n = 785). Study design: parallel.
- Japanese patients with prior ischemic stroke 1 month to 3 years ago
- Total cholesterol 180-240 mg/dl
- Age >45 years, <80 years
- Total number of enrollees: 1,578
- Duration of follow-up: mean 4.9 years
- Mean patient age: 66 years
- Percentage female: 31%
- Percentage diabetics: 23%
- Other salient features/characteristics: Mean systolic blood pressure = 137 mm Hg
- Cardioembolic stroke
The primary outcome, any cerebrovascular event, occurred in 2.56%/year in the low-dose pravastatin group versus 2.65%/year in the control group (p = NS).
- Atherothrombotic infarction: 0.21%/year vs. 0.65%/year (p < 0.05), respectively
- Any death: 0.90%/year vs. 1.11%/year, respectively
- Hemorrhagic stroke: 0.31%/year vs. 0.31%/year, respectively
Among Japanese patients with prior ischemic stroke, low-dose pravastatin did not prevent recurrent cerebrovascular events, although it did prevent atherothrombotic infarction. The follow-up period was long; however, the dose of pravastatin that was tested may have been too low to prevent recurrent cerebrovascular events.
