Aims: This study aimed to investigate the long-term impact of guideline-directed medical therapy (GDMT) on 10-year mortality in patients with chronic limb-threatening ischaemia (CLTI) after revascularization. Methods: We performed a retrospective multicentre study enrolle 459 patients with CLTI who underwent revascularization (396 endovascular therapy [EVT] and 63 bypass surgery [BSX] cases) between January 2007 and December 2011. The primary outcome measure was all-cause mortality. We additionally explored the predictors for all-cause mortality using Cox regression hazard models; the influence of GDMT, defined as prescription of antiplatelet agents, statins, and angiotensin converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs) in aggregate, on all-cause mortality, and the association between baseline characteristics using interaction effects. Results: During the 10-year follow-up after revascularization, 234 patients died. In Kaplan-Meier analysis, 10-year mortality was significantly lower in patients who received statins (p<.001) and ACE inhibitors or ARBs (p=.010) than those who did not. However, there were no differences in 10-year mortality between patients who received anti-platelet agents and those who did not (p=.62). Interaction analysis revealed that GDMT had a significantly different hazard ratio in patients who were and were not on hemodialysis and in those treated with EVT or BSX (p for interaction =.002 and .044, respectively). In the multivariate analysis, age >75 years, non-ambulatory status, hemodialysis, congestive heart failure, left ventricular ejection fraction <50%, and GDMT were significantly associated with all-cause mortality. Conclusions: Appropriate GDMT use was independently associated with 10-year mortality in patients with CLTI after revascularization.
