AbstrakUntuk lebih memahami gambaran karakteristik, waktu tiba, pola klinis, faktor risiko, jenis stroke, Iama rawat, dan status keluaran dari pasien stroke akut di negara-negara ASEAN 44 participating hospitals in this study ie Brunei (n=53), Indonesia (n=2065), Malaysia (n=300),Philippines (n=545),Singapore (n=2j2),Thailand (n=244) and Vietnam (n=284), the mean age was 59.0 + 13,8 years 16 Vo of patients were younger than 45 years and 37 Vo of patients were older than 65 years. There were no significant differences in age at onset among stroke subjects except in Vietnam (younger) and Singapore (older).The sex distribution showed a slight higher prevalence of women in Singapore and in the age group > 64 years. The mean adrnission time was 41.5 + 87.0 hours, 19Va of patients were admitted within 3 hours, 29Vo within 6 hours and 66Vo more than 6 hours (delayed admission) especially in Malaysia and Singapore (80Vo and 77Vo respectively). Motor disability was the most prevalent clinical feature in all counties and carotid bruit was the rarest (IVo).Hypertension was the most comnnon riskfactor (68Vù in all countries, followed by TIA (35Vo), smoking, diabetes mellitus, ischnemic heart disease and hypercholesterolemia. CT scan was performed on 76 Vo of subjects. The diagnostic classification \eas non lacunar anterior circulation (32Vo), lacwnar infarction (14Vo), hemonhagic stroke (26Eù, SAH (4Eo).Mean length of stay was I1.4 + I L8 days. Most of the patients discharged from the hospiîal were alive improved (57Vo) and mean death rate was 22 Vo, highest in Thailand (45Vo) and lowest in Brunei (8Vo). This hospital based stroke data showed the recent characteristics of stroke pattern in seven ASEAN member countries and it wilL be very important data for heatth policy maker in these countries and for further cooperative researches in the future.
