(A) Light transmission aggregometry (LTA) determination of % final aggregation at 6 minutes in response to AA (1mmol/L), ADP (5μmol/L), ADP (20μmol/L), collagen (0.4μg/mL), collagen (4μg/mL), collagen (10μg/mL), TRAP-6 amide (25μmol/L) and U46619 (10μmol/L) compared to age (n=139–184) or (B) 10-year cardiovascular risk by Framingham Heart Study (FHS) risk score (n=137–181) measured in the absence of aspirin use. r indicates the correlation between final aggregation and age or FHS risk score using Spearman correlation.
