Transcutaneous oxygen pressure as a predictor for short-term survival in patients with type 2 diabetes and foot ulcers: a comparison with ankle–brachial index and toe blood pressure

摘要

Aims Ankle–brachial index (ABI) is the most commonly used test when diagnosing peripheral vascular disease and is considered a marker for cardiovascular risk. Transcutaneous oxygen pressure (TcPO~(2)), a test associated with microvascular function, has in several studies shown better correlation with diabetic foot ulcer (DFU) healing. Whether a low TcPO~(2)could be a marker for mortality in the high-risk population of DFU patients has not been evaluated before. The aim of this study was to evaluate the predictive value of TcPO~(2)in comparison with ABI and toe blood pressure (TBP) on 1-year mortality in type 2 diabetes patients with DFU. Methods Type 2 diabetes patients aged?≤?90?years, with one DFU who attended our multidisciplinary DFU-unit during year 2013–2015 and were screened with TcPO~(2), ABI and TBP were retrospectively evaluated. One-year mortality was assessed from the national death register in Sweden. Results A total of 236 patients (30% women) with a median age of 76 (69–82) years were evaluated in this study. Within 1?year, 14.8% of the patients died. TcPO~(2)?
