Abstract:
Objective To evaluate the prevalence of aspirin resistance in old-aged patients with cerebral infarction and to analyze the mechanisms and clinical predictors of aspirin resistance. Methods 300 old-aged patients with cerebra] infarction were selected and the platelet aggregation ratio was determined by nephelometry with CHRONO-LOG PA-meter. And some information of these patients, such as age, sex, smoking, taking non-steroid anti-inflammatory drug (NSAD)or proton pump inhibitor (PPI), obesity, coronary artery disease (CAD), peripheral vascular disease, hyperpiesia, diabetes and hyperlipemia were recorded. Results 112 cases (37.33%) were aspirin sensitiveness, 108 cases(36.0%) were aspirin semi-resistance and 80 cases (26.67%) were aspirin resistance. These cases were divided into two groups. One was aspirin sensitive (AS) group, which included 112 patients of aspirin sensitiveness. The other was aspirin resistant (AR) group, which consisted of 188 patients of aspirin semi-resistance and aspirin resistance. The prevalence of CAD, hypercho]esteremia and RBC count in AR group was higher than that in AS group The percentage of patients who took NSAD, PPI and smoke in AR group was also higher than that in AS group. Conclusion Aspirin resistance existed in old-aged patients with cerebral infarction to great extent, and which was correlated with CAD, hypercholesteremia, smoking, RBC count, taking NSAD and PPI.
