Abstract:
Objective To study the effects of atorvastatin on contrast induced renal function change and plasma hsCRP in patients undergoing coronary angiography. Methods 120 patients who underwent coronary angiography were randomized to receive atorvastatin (20 mg/qn, n = 60) or no atorvastatin (n =60) treatment 2 to 3 days before coronary angiography. Urinary α1-MG, TRF and mALB were checked for evidence of tubular or glomendar damage at start, 1 day and 2 days after the administration of a radiocontrast agent. Serum creatinine, BUN, cystatin C and hsCRP levels were also assessed at the same time. Ccr and GFR were calculated according to Cockcroft-Ganh and GFR(ml/min) = 74. 835/Cys C1.333formulas basing on serum creatinine or cystatin C concentration. Results (1) In control group, comparison with the value before coronary angiography,urinary α1-MG, TRF and mALB or serum cystatin C and hsCRP significantly increased at day 1 after angiography (P ＜ 0.01). In comparison to the levels at day 1 after angiography, urinary α1-MG, TRF, mALB, serum cystatin C significantly decreased at day 2 after angiography(P ＜ 0.01), but α1-MG, cystatin C still exceeded the values before coronary angiography, TRF and mALB levels at day 2 after angiography had no significant change compared to baseline(P ＞0.05), hsCRP LeveL at day 2 after angiography had no significant change compared to that at day 1 after angiography (P ＞ 0.05) too. (2) In comparison with the value before coronary angiography in atorvastatin-treated group, the levels of urinary α1-MG, TRF and mALB or serum cystatin C at day 1 and day 2 after angiography had no significant change compared to baseline(P ＞0.05). Serum hsCRP significantly increased at day 1 after angiography compared to baseline(P ＜ 0.01), but it had no significant change compared to day 2 after angiography (P ＞ 0.05). (3)To compare to the atorvastatin-treated group, the values of urinary α1-MG, TRF and mALB or Cys C and hsCRP significantly increased at day 1 after angiography in control group (P ＜ 0.01), the values of urinary α1 -MG, cystatin C and hsCRP still significantly increased at day 2 (P ＜ 0.01) too, but those of TRF and mALB had no significantly change at day 1 or day 2 after angiography between the two groups (P ＞ 0.05). There was no significant change in BUN, Cr, Ccr levels before and after angiography between the two groups. Conclusions Low dose contrast induces light renal function damage. Pretreatment with atorvastatin 20 mg/qn for 2 to 3 days could significantly reduce procedural inflammatory reaction, attenuate urinary protein and the effect of degrading GFR in coronary angiography patients.
