non-cardiac, diabetic
142 diabetic patients on metformin therapy were included. Median preprocedural lactate level was 1.8 mmol/l [interquartile range (IQR) 1.3–2.3]. Lactate levels at 72 h after coronary angiography were 1.7 mmol/l (IQR 1.3–2.3), with no significant differences as compared to preprocedural levels (p = 0.91; median difference = 0; IQR − 0.5 to 0.4 mmol/l). One patient had 72-h levels ≥ 5 mmol/l (5.3 mmol/l), but no cases of M-ALA were reported. CA-AKI occurred in 9 patients (6.1%) and median serum creatinine and estimated glomerular filtration rate remained similar throughout the periprocedural period. At a median follow-up of 90 days (43–150), no patients required hemodialysis and 2 patients died due to non-cardiac causes.
