Risk stratification at presentation with acute coronary syndromes (ACS) on the basis of the TIMI risk score for unstable angina and non-ST-elevation myocardial infarction (UAP/NSTEMI) identifies patients at high risk of recurrent cardiac events and those who benefit from more aggressive treatment strategy. We hypothesised the following: (a) that a high TIMI risk score brings a greater degree of acute changes in endothelial damage/dysfunction (circulating endothelial cells [CECs], von Willebrand factor [vWf]), inflammation (interleukin-6, IL-6) and blood thrombogenicity (plasma tissue factor, TF); and (b) that these indices are higher in those with high TIMI risk score who experienced recurrent cardiac event at day 14 and day 30. TIMI risk scores were determined at admission and 48 hours later in 88 ACS patients (60 male, age 67+/-12 yrs) with UAP or NSTEMI. CECs, IL-6 and TF levels were measured at both time points and the acute change (delta) calculated. Patients were split into high (score > or =4) or low (
