Differences in major limb outcomes by indication for lower extremity endovascular revascularization in patients receiving hemodialysis

This study is to determine whether indication of PAD has a distinct impact on major adverse cardiovascular and cerebrovascular events (MACCE) and limb events in patients receiving hemodialysis. The current study included 2321 prospectively enrolled patients from the Tokyo taMA peripheral vascular intervention research ComraDE registry (UMIN-CTR no. UMIN000015100) between September 2014 and December 2016. Out of the enrolled patients, 1644 were not receiving hemodialysis (non-HD patients) and 603 were receiving hemodialysis (HD patients). A composite of all-cause death, myocardial infarction, and stroke events defined as MACCE; while limb events were defined as a composite of unscheduled major amputation, unscheduled major lower limb surgery, acute limb ischemia, unscheduled endovascular treatment, and target lesion revascularization. Propensity score matching was applied among the non-HD and HD patients, in whole group, IC subgroup, and CLTI subgroup. Kaplan –Meier analysis was used for the analysis of outcomes for the whole group, IC subgroup, and the CLTI subgroup. CLTI accounted for 75.5% of the HD patients, whereas IC was 63.4% in the non-HD patients. The HD patients exhibited more frequent below-the-knee lesions than those in the non-HD patients in both IC (p = 0.01) and CLTI (p <  0.001) subgroups. Overall, HD patients exhibited a significantly higher rate of MACCE at 24 months. This trend was similar for limb events in whole group and CLTI subgroup. In co...
