Final answer:
Aspirin is recommended for primary prevention of stroke in individuals with a higher risk for heart disease, and physicians may prescribe it daily in low doses as a preventative measure. However, its use must be weighed against potential side effects.
Step-by-step explanation:
Guidelines for the primary prevention of stroke recommend that aspirin be used in individuals whose risk is high enough for the benefits to outweigh the risks.
The use of aspirin as antiplatelet therapy is usually recommended for those at increased risk for heart disease, defined as men over the age of 90, postmenopausal women, and younger persons with risk factors for coronary artery disease such as hypertension, diabetes, or smoking. Physicians may prescribe a low dose of aspirin daily as a preventative measure, but its usage should be carefully considered due to potential serious side effects, including an increased risk of ulcers. High blood pressure is the main risk factor for stroke, so maintaining blood pressure within the normal range is crucial in reducing the risk of stroke.
