    Abstract
    Background : High level of cholesterol is the risk factor for ischemic stroke. Early treatment with statins may reduce plasma lipid level and, therefore improve outcomes of acute ischemic stroke. Objective : This study was performed to determine the effects of dosage of statins on the level of plasma lipid and functional outcome in ischemic stroke. Methods : Randomized, control-group, pretest-postest design was used in this study. The subjects was divided by 3 groups, the first used Simvastatin 10mg, the second used 20mg, and the third used Atorvastatin calcium 20mg, which of 12 patients for each group. The average of plasma lipid was measured three times, the first was before treatment, then followed in day 14th and 28th after treatment. To determine the difference of plasma lipid, before and after treatment, Anova test (p<0,05) was used. Outcome was measured with NIHSS (≤5=mild;6-13=moderate;>13 severe) and mRS (1-2=good;3-6=poor), and changes of outcome was determined by using the Wilcoxon test. Results : From 12 samples for each group, Simvastatin 10mg reduced total cholesterol (p=0,01) and triglyceride level (p=0,0001), Simvastatin 20mg reduced total cholesterol (p=0,003) and triglyceride level (p=0,0001). Atorvastatin calcium 20mg reduced the total cholesterol (p=0,0001), triglyceride (p=0,008) and LDL level (p=0,0001). Atorvastatin calcium 20mg improved outcome in NIHSS and mRS score was significant (p=0,025). Conclusion : This study suggested that early treatment with atorvastatin calcium 20mg for acute ischemic stroke could reduce the plasma lipid level and improved functional outcome more significant than Simvastatin 10mg and 20mg.
     
    Latar Belakang : Kadar kolesterol yang tinggi merupakan faktor resiko untuk stroke iskemik. Pemberian segera statin kemungkinan dapat menurunkan kadar lipid plasma sehingga akan menghasilkan outcome yang lebih baik pada pasien stroke iskemik akut. Tujuan : Studi ini dilakukan untuk mengetahui adakah pengaruh dosis statin terhadap kadar lipid plasma dan outcome fungsional pada pasien stroke iskemik. Metode : Penelitian ini menggunakan metode eksperimen dengan rancangan randomized control-group pretest-postest design. Penelitian dilakukan terhadap 3 kelompok, yaitu pemberian Simvastatin 10mg, 20mg, dan Atorvastatin calcium 20mg, dengan jumlah 12 pasien per kelompoknya. Kadar lipid plasma diukur tiga kali, sebelum pengobatan, setelah pengobatan hari ke-14, dan ke-28. Untuk mengetahui perbedaan rerata kadar lipid plasma sebelum dan sesudah pengobatan pada ketiga kelompok digunakan uji Anova, dengan taraf signifikan p<0,05. Outcome dinilai dengan menggunakan NIHSS (≤5=stroke ringan;6- 13=sedang;>13=berat) dan mRS (1-2=baik;3-6=buruk), dan untuk melihat perubahan outcome tiap kelompok digunakan uji Wilcoxon(p<0,05). Hasil : Dari 12 sampel tiap kelompoknya, Simvastatin 10mg menurunkan secara bermakna rerata kadar total kolesterol(p=0,01) dan trigliserida(p=0,0001), Simvastatin 20mg menurunkan secara bermakna rerata kadar total kolesterol(p=0,003) dan trigliserida(p=0,0001). Atorvastatin calcium 20mg menurunkan secara bermakna rerata kadar total kolesterol(p=0,0001), trigliserida(p=0,008) dan LDL(p=0,0001). Perubahan skor outcome NIHSS dan mRS yang bermakna terjadi pada kelompok yang diberikan Atorvastatin calcium 20 mg (p=0,025) Kesimpulan : Studi ini menunjukkan bahwa penggunaan Atorvastatin calcium 20mg segera setelah serangan stroke iskemik, dapat menurunkan kadar lipid plasma dan perubahan outcome lebih bermakna dibandingkan dengan Simvastatin 10 dan 20 mg.
