The primary objective of the study is to determine the prevalence of aspirin resistance in chronic kidney disease patients. The secondary objectives are to determine possible risk factors contributing to aspirin resistance in this population.
Condition or disease
Chronic Kidney Disease
A cross-sectional of "aspirin resistance in hemodialysis patients" previously done in our institution showed that 23/66 (34.7%) hemodialysis patients were aspirin resistant. In a recent systematic review, renal impairment was associated with aspirin resistance . This association was seen in only two out of the twenty studies used in this meta-analysis . Both these studies are from the same center with a predominant Asian population. In this study we will try to evaluate the prevalence of aspirin resistance in CKD patient without being limited to a specific ethnicity.
