Background

In hemodialysis (HD) patients, peripheral artery disease (PAD) remains a critical cardiovascular complication which is usually diagnosed by ankle brachial index (ABI). Far infrared therapy improves access flow of vascular access but the effect on PAD in HD patients is still unknown.

Methods

We enrolled 198 maintenance HD patients in this study. PAD was defined as ABI ≤ 0.90. Only PAD patients received WS TY101 FIR emitter (Firapy) for 40 minutes during each HD session, three times weekly for six months. The ABI was measured for bilateral lower extremities for 4 times [pre-dialytic timing (0 minute) and 40 minutes after the initiation of HD session at both day 0 and 6 months after the FIR therapy].

Results

Fifty-one out of 198 patients had PAD. In comparison with the period without FIR therapy in the 51 PAD patients, 6 months of FIR therapy significantly improved the ABI of right/ left side for 0 minute (from 0.77±0.19 to 0.81±0.20, P=0.027/0.79±0.20 to 0.81±0.17, P=0.049), 40 minutes during HD (from 0.73±0.23 to 0.83±0.19, P<0.001/ from 0.77±0.21 to 0.83±0.18, P<0.001) and incremental change between 0 and 40 minutes (from -0.04±0.14 to 0.02±0.13, P= 0.007/ from -0.02±0.13 to 0.02±0.14, P=0.012) respectively.

Conclusion

We demonstrate 40 minutes of FIR therapy three times weekly for 6 months improved ABI of both lower extremities, thus providing a new strategy for the treatment of PAD in HD patients.
