Background : Serum hemoglobin (H) level is a well‐known predictor of all‐cause mortality in patients undergoing percutaneous coronary interventions but has not been studied in patients undergoing peripheral vascular interventions (PVI). We sought to determine the prognostic significance of serum H in patients undergoing PVI. Methods : We identified 346 consecutive patients undergoing PVI who had a documented a baseline and a postprocedural serum H level over a 33‐month period. A multivariate analysis of predictors of 9‐month mortality was performed. Results : Of 346 patients identified, there were 28 deaths (8.1%) over a 9‐month follow‐up period. Periprocedural H change was not associated with death [OR: 1.12 (95% CI: 0.71–1.79), P = NS]. In a multivariate model independent predictors of all‐cause mortality were clinical bleeding [OR: 10.7 (95% CI: 0.012–0.769), P = 0.026], emergency intervention [OR: 4.5 (95% CI: 0.07–0.71), P = 0.011], ejection fraction [OR: 1.02 (95% CI: 1.01–1.05), P = 0.020], and preprocedural H [OR: 1.56 (95% CI: 1.19–2.04) P = 0.001]. Conclusion : In patients undergoing PVI, preprocedural H was a significant predictor of 9‐month all‐cause mortality. The highest mortality rate was seen in patients with a preprocedural H level ≤ 10 g/dl. Preprocedural H level can be used in clinical practice to risk stratify patients being considered for PVI. Further investigation is needed to assess if optimization of H level preprocedure improves midterm mortality. © 2011 Wiley‐Liss, Inc.
