Thank you for your query at DoctorSpring.com,.
I understand your concern.
Yes, Aspirin and Atorvastatin(Lipitor) are helpful in preventing a second stroke. Lipitor helps in secondary prevention of stroke even if you have normal cholesterol values.
I do not know where you found the information that Aspirin does not help in men, but that is NOT true. As you know, most of the information present online is usually not reviewed or verified. Hence not all of it can be true.
Aspirin, which is the most commonly used anti-platelet agent, inhibits the enzyme called cyclooxygenase, preventing platelets from aggregating. This interferes with the formation of thrombi(clots), thereby reducing the risk of stroke. The effectiveness of aspirin for preventing ischemic stroke and cardiovascular events is supported by a large number of clinical trials. These trials demonstrated that Aspirin reduced the risk of secondary stroke, MI(heart attack), or vascular death and this benefit was INDEPENDENT OF SEX, age (greater or less than 65), diabetes, or hypertension.
Be rest assured that you are receiving the right treatment. I hope that clears your doubt.
