The Comorbidity-Polypharmacy Score as a Predictive Tool of Survival and Limb Salvage in Patients Undergoing Lower Limb Revascularization Procedures for Chronic Limb-Threatening Ischemia.

Background: The comorbidity-polypharmacy score (CPPS) was created to evaluate the clinical burden of comorbidities in geriatric patients. It represents an objective tool to stratify patients' risk in different settings. The study aimed to evaluate CPPS in predicting mortality and amputation in patients undergoing elective revascularization procedures in chronic limb-threatening ischemia (CLTI) patients.
