Contrast-induced nephropathy (CIN) is an important complication following percutaneous coronary intervention (PCI). The clinical importance of a minimum contrast media volume (CMV) for PCI to prevent CIN has not been well evaluated. The purpose of this study was to evaluate the impact of minimum CMV to prevent CIN after PCI. In this study, 2052 consecutive patients who underwent elective PCI in our institute were analyzed. We divided patients into two groups according to CMV: a minimum CMV PCI group [CMV ≤50 ml (n = 94)] and a non-minimum CMV PCI group [CMV >50 ml (n = 1958)]. CIN occurred in 160 (7.8 %) patients. The incidence of CIN was significantly lower in the minimum CMV PCI group than in the non-minimum CMV PCI group (2.1 vs. 8.1 %; P = 0.03). According to multivariate analysis, elderly patients and diabetes mellitus patients were at high risk of developing CIN in this study population. When analyzing only high-risk patients, the incidence of CIN was also significantly lower in the minimum CMV group than in the non-minimum CMV group (2.6 vs. 10.3 %; P = 0.03). Minimum CMV PCI could reduce the incidence of CIN, particularly in high-risk patients; as such, defining the minimum CMV clinical cut-off values may be useful for the prevention of CIN.
