Low-molecular-weight dextran for optical coherence tomography may not be protective against kidney injury in patients with renal insufficiency

Figure 1 The patient population in this study. CAG: Coronary angiography; eGFR: Estimated glomerular filtration rate; LMWD: Low-molecular-weight dextran; OCT: Optical coherence tomography; PCI: Percutaneous coronary intervention.

Figure 2 Serial comparison of serum creatinine levels at baseline, and within 5 d, 1 mo, and 1-year post-procedure. A: Entire study cohort. Renal function was consistently lower in the low-molecular-weight dextran (LMWD) group than in the control group; B: Propensity score-matched cohort. The LMWD group demonstrated a trend toward worsening renal insufficiency during the 1-year follow-up compared with the control group. LMWD: Low-molecular-weight dextran.

Figure 3 Prevalence of worsening renal function stratified by the cut-off values for low-molecular-weight dextran volume and baseline estimated glomerular filtration rate level in propensity score-matched cohort. eGFR: Estimated glomerular filtration rate; LMWD: Low-molecular-weight dextran.
