Skin Perfusion Pressure and the Prevalence of Atherothrombosis in Hemodialysis Patients.
End-stage renal disease is associated with atherothrombosis (ATIS), which, in turn, can promote peripheral arterial occlusive disease (PAOD), coronary artery disease (CAD), and/or cerebrovascular disease (CVD). The aim of this study was to determine whether low plantar skin perfusion pressure (SPP) was related to ATIS among 122 patients receiving maintenance hemodialysis (HD) from March to November 2013 at our outpatient facility. We routinely measured SPP and used the value for analysis. In addition, we retrospectively evaluated the prevalence of ATIS with patients categorized to CAD, CVD, or PAOD groups. Of the 122 outpatients, ATIS was diagnosed in about half (N = 60, 49.2% vs. 62, 50.8%; average SPP, 56.6 vs. 72.9 mm Hg, respectively). These data show that SPP was significantly lower in patients with ATIS (difference, 16.3 mm Hg; P < 0.001) and there was a negative relationship between average SPPs and past history of ATIS complications. When the patients were stratified by the presence of diabetes mellitus, this trend was stronger. Particularly, receiver operating characteristic analysis of HD patients with diabetes revealed a cutoff point of 53.0 mm Hg and an area under the curve value of 0.84, with a sensitivity of 77.0% and specificity of 91.3%. Therefore, we concluded that SPP enables the evaluation of not only local PAOD, but also systemic ATIS. Moreover, we found that a cutoff point of 53.0 mm Hg was useful for detection of ATIS in HD patients.
