Hi sir , I have a dowt If a patient on day of admission not window period Ct showing acute infarct Clinically patient is NIHS score is 12 So ideally starting on single antiplatelet but after 24 to 48 hrs or during hospital stay nihss core improved to 4(mild category) So then either we should increase single antiplatelet to dual antiplatelet or continue single antiplatelet for 21 days ?
