Individuals with atrial fibrillation without concomitant risk factors should be treated with acetylsalicylic acid (ASA; 100-300 mg/d)
Primary prevention of apoplexy by acetylsalicylic acid (ASA) has very limited efficacy in men; in women with vascular (“vascular-related”) risk factors, risk reduction is rather small.
Taking ASA around 10 p.m. leads to more pronounced platelet inhibition in the cardiovascularly critical morning hours
