The objective of this study was to assess whether polymorphisms in UGT1A6 and CYP2C9 genes are related to the prevalence of upper gastrointestinal symptoms in cardiovascular patients using acetylsalicylic acid for secondary prevention of ischaemic heart disease.
In conclusion, in three independent studies totaling more than 52 000 individuals, we found no association between CYP2C9(*)2 and CYP2C9(*)3 polymorphisms and risk of subclinical atherosclerosis, ischemic vascular disease or death after ischemic heart disease.
