ABSTRACT
The aim of this prospective cross-sectional study was to reveal clinical characteristics of Japanese diabetic patients with chronic limb-threatening ischemia (CLTI) presenting ischemic unhealed ulcer/gangrene (Fontaine stage IV) in the real-world settings. The present study included 132 Japanese diabetic patients who underwent endovascular therapy for CLTI presenting Fontaine stage IV. The prevalence of diabetes-related complications, as well as prior history of ankle-brachial index (ABI) measurement before CLTI onset, was evaluated adopting multiple imputation (50 times). Duration of diabetes was referred to as time from diagnosis. The patients were aged 70 ± 10 years, with duration of diabetes 23 ± 12 years. The diabetes-related complications were so common that only 17% (95% confidence interval: 11-24%) and 25% (17-33%) of the population were free from advanced micro- and macroangiopathies, respectively. The clustering of advanced macroangiopathies was not significantly associated with duration of diabetes (P = 0.62). On the other hand, that of advanced microangiopathies was significantly positively associated with duration of diabetes (P = 0.004). However, even in patients with duration of diabetes < 10 years, as many as 63% (38-87%) of patients had at least one advanced microangiopathy. Only 31% (22-39%) of the patients had prior history of ABI measurement before CLTI onset. The history was inversely associated with age (P = 0.005). In conclusion, the advanced diabetes-related complications were highly prevalent, even in those whose diabetes was diagnosed less than a decade before. In addition, only a few patients had ever undergone ABI measurement before CLTI onset.
