目的探讨老年人行冠状动脉造影术和冠状动脉介入治疗(PCI)后造影剂肾病(RCIN)的发生率和相关的危险因素。方法回顾性分析老年住院患者使用造影剂前后血清肌酐的变化。结果老年患者RCIN发生率为15.4%。合并肾功能不全、造影剂用量>150 mL、糖尿病、充血性心力衰竭及高血压病的患者RCIN发生率增加。结论老年人RCIN发生率高,肾功能不全是最主要危险因素。
Objective To investigate the incidence and related risk factors of contrast-induced nephropathy (RCIN) in the elderly after coronary angiography and coronary intervention (PCI). Methods The changes of serum creatinine in elderly hospitalized patients before and after using contrast agent were retrospectively analyzed. Results The incidence of RCIN in elderly patients was 15.4%. With renal insufficiency, the amount of contrast agent> 150 mL, diabetes, congestive heart failure and hypertension in patients with an increased incidence of RCIN. Conclusion The incidence of RCIN in the elderly is high, renal insufficiency is the most important risk factor.
