Abstract

Background: Peripheral arterial disease (PAD) causes significant morbidity today. Atherosclerosis is evident in the pathophysiological process in most patients, so PAD has similar risk factors as coronary artery disease. Platelet-Hemoglobin ratio (PHR) has been proven to predict mortality in atherosclerotic heart disease. We aimed to determine the relationship between PHR and below-knee amputation. Methods: The study is a single-center retrospective study. Platelet count/hemoglobin amount formula was used for PHR. Only PAD patients with below-knee critical extremity ischemia and unsuitable for revascularization were included in the study. Results: 235 patients were included in the study retrospectively. The mean age was 65.7 ± 9.9 years and 175(74.5%) of them were male. In the amputated group, white blood cell, neutrophil, platelet, creatinine, glucose, and PHR were higher (p =.031, p =.045, p =.011, p =.048 p =.018, p =.004, respectively). Only hemoglobin values were lower (p =.003). Multivariable regression analysis showed; age, albumin and PHR were determined as independent risk factors for amputation (Age; OR (95%CI): (1.094(1.040–1.152), p =.001) (Albumin; OR (95% CI): 1.950(1.623–1.799), p =.001) (PHR; OR (95% CI): 1.872(1.246–2.812), p =.003). Receiver operating characteristics analysis performed to determine the optimal cut-off value of PHR for amputation, the optimal value was found 2.08 (65.8% sensitivity, 67.5% specificity, p <.001). Conclusions: PHR was a good predictor for BKA. Using the PHR, it may be possible to identify high-risk patients for amputation.
