About

Ischemic cardiovascular and cerebrovascular diseases are the main causes of death among people. Antiplatelet threrapy is very important for patients to prevent ischemic cardiovascular and cerebrovascular diseases.Ischemic cardiovascular patients of cerebral amyloid angiopathy (CAA) patients is as high as 20%, aspirin and clopidogrel is applied to prevent or treat the patient with CAA is controversial, there is no valid evidence of CAA crowd is safe to use of antiplatelet drugs, but progress in clinical treatment is usually based on patient condition for antiplatelet agents to prevent the occurrence of adverse events, such as blood clots.Therefore, this study is intended to be a single-center, prospective study of patients with ischemic cardiovascular and cerebrovascular diseases taking aspirin and clopidogrel, to determine whether the patients are combined with CAA , and to conduct a follow-up study for 12 months after team inclusion:1) The prevalence rate and gene spectrum of ischemic cardiovascular and cerebrovascular diseases among CAA patients enrolled in our hospital were analyzed;2) To explore the correlation between aspirin and clopidogrel drug genes and blood drug concentrations and diseases in patients with ischemic cardiovascular and cerebrovascular diseases complicated with CAA;3) To evaluate the efficacy and safety of aspirin and clopidogrel in patients with ischemic cardiovascular and cerebrovascular diseases who combined with CAA.

Full description

This project intends to observation of bleeding the application of antiplatelet in patients with CAA, so as to provide effective clinical evidence for the further application of clopidogrel and aspirin in patients with CAA in the future, and to provide reference basis for the accurate formulation of clinical treatment plans and the balance of health risks brought by adverse bleeding reactions.
