RESUMEN
BACKGROUND This study aimed to compare the ankle-brachial index (ABI), maximal claudication distance (MCD), pain-free walking distance (PFWD), claudication pain, and quality of life (intermittent claudication questionnaire [ICQ]) before and 3 months after revascularization surgery in 98 patients diagnosed with peripheral arterial disease (PAD) at a single center in Poland. MATERIAL AND METHODS Ninety-eight patients were examined (77% men, 23% women, 65.65±7.27 years old), diagnosed with PAD, and qualified for revascularization. The diagnosis of PAD was made on the basis of ABI ≤0.9 and medical records. The patients underwent a noninvasive examination, including measurement of ABI (by Doppler with the EZ8 probe), assessment of the quality of life by ICQ, distance of intermittent claudication on a treadmill using the Gardner-Skinner protocol (including PFWD and MCD), and pain intensity during walking (numeric rating scale [NRS11]). The assessment was carried out twice: 1 to 5 days before surgery and 3 months after surgery. RESULTS There was an increase of ABI (0.4 vs 0.62, P<0.001), PFWD (26.64 vs 80.21, P<0.001), MCD (60.08 vs 181.85, P<0.001), and ICQ (79.92 vs 60.23, P<0.001) and reduction of PFWD pain (7.26 vs 6.05, P<0.001) and MCD pain (9.24 vs 8.11, P<0.001). CONCLUSIONS Revascularization surgery improved the ABI and patients functional efficiency expressed in the improvement of subjective indicators PFWD, MCD, NRS11, and ICQ. Patients who had a longer duration of disease had worse outcomes after revascularization. More attention should be paid to increasing access to preventive examinations aimed at early detection of PAD and the possibility of implementing conservative treatment.
