AIMS: To determine the association of glomerular filtration rate (GFR) with clinical outcomes in the setting of non-ST-segment elevation acute coronary syndromes (NSTE-ACS).

METHODS: Data were pooled from five NSTE-ACS TIMI trials (TIMI 11A and B, TIMI 12, OPUS-TIMI 16 and TACTICS-TIMI 18) and were available in 13 307 patients. GFR was assessed as a continuous and a categorical variable (normal: > or = 90 mL/min/1.73 m2, n=4952; mildly decreased: 60-89 mL/min/1.73 m2, n=6262; and moderately to severely decreased GFR: <60 mL/min/1.73 m2, n=2093). There was an independent association between decreasing GFR and mortality at 30 days (OR 1.19, 95% CI 1.12-1.27, p<0.001) and at 6 months (OR 1.16, 95% CI 1.11-1.22, p<0.001). The combination of TIMI risk score (TRS) and decreasing GFR provided further mortality risk stratification with highest 30-day and 6-month mortality rates among patients with the lowest GFR who also had a TRS > or = 5 (9.1% and 15.4%, respectively). Decreasing GFR was also independently associated with stroke and recurrent ischaemia at 30-days as well as with major bleeding (p<0.001). CONCLUSION: In the setting of NSTE-ACS, impaired GFR is associated with higher mortality as well as higher rates of thrombotic and major bleeding events, independent of TRS.
