BACKGROUND/AIMS: Contrast induced nephropathy (CIN) is associated with adverse clinical outcomes in patients undergoing coronary interventions, particularly in patients with advanced chronic kidney. The study was aimed to assess the real-life feasibility and safety of ultra-low volume coronary procedures in patients with advanced chronic kidney disease.
METHODS: A prospective study that included patients with an estimated glomerular filtration rate (eGFR) <45 mL/min/1.73 m2) was conducted. Coronary procedures were performed using an ultra-low contrast volume technique.
RESULTS: The 30 patients had a mean eGFR of 31.8(±8) mL/min/1.73 m2. Indications for coronary angiography were non-ST elevation myocardial infarction (63.3%), unstable (20%), and stable angina pectoris (16.7%). Median contrast volume for diagnostic coronary angiography was 13 mL (interquartile ranges [IQR] 12-14.9), and an additional 13 mL (IQR 8.8-14.3) for percutaneous coronary intervention (PCI). In 3 patients (10%), a ≥25% increase was demonstrated in serum cystatin C levels 48 h following the procedure. None of the patients demonstrated a ≥25% increase in serum creatinine levels at 48 h. Following 6 months, no patient required renal replacement therapy or unplanned coronary intervention.
CONCLUSIONS: In patients with advanced chronic kidney disease, the ultra-low contrast technique is feasible and effective and can be used safely without a significant deterioration in renal function. This technique may increase the utilization of PCI in high-risk coronary patients with chronic kidney disease.
