A previous study suggests that critical limb ischemia (CLI) patients who are unlikely to live 2 years are better served by endovascular treatment (EVT) for the first revascularization. In this study, we investigated the predictors of early mortality in patients with CLI due to isolated below–the–knee (BTK) artery disease and to identify patients with an estimated life expectancy of 2 years or less.
This was a multicenter retrospective observational study. From March 2004 to June 2011, a total of 884 patients with CLI who underwent angioplasty for isolated BTK artery disease were enrolled.
The mean follow–up period was 20 ± 18 months. Cox multivariate regression analysis showed that body mass index < 18, serum albumin level < 3g/dl, non–ambulatory status, ejection fraction < 45%, and presence of cerebro–vascular disease were positively associated with all–cause death within 2 years. The sum of the number of risk factors was used to classify patients into three groups: low–risk group (0–1 risk factor), moderate–risk group (2 risk factors) and high–risk group (3–5 risk factors). Kaplan–Meier survival curve showed that the freedom from all–cause death at 2 years was 79.0% in the low–risk group, 50.1% in the moderate–risk group and 30.1% in the high–risk group.
Patients who have more than two of risk factors are supposed to have an estimated life expectancy of 2 years or less and may indicate EVT first revascularization.
