摘要

Background/Purpose: To investigate contemporary cardiovascular (CV) outcomes in Taiwanese patients with symptomatic low extremity peripheral artery disease treated with endovascular therapy. Methods: An observational cohort study with up to 155 months of follow-up was conducted using a single-center registry database between July 2005 and June 2017. Long-term outcomes and predictors of future CV events were analyzed in 936 patients with 1246 affected legs. Results: This study cohort comprised 21% claudicants and 79% critical limb ischemia (CLI) patients. Compared with claudicants, CLI patients had higher rates of medical comorbidities, tissue inflammation, and lesion complexities. During the study period, 349 patients died (130 CV deaths and 219 non-CV deaths), 306 had non-fatal CV events. The rates of 5-year freedom from all-cause mortality, major CV events (MACEs), and non-fatal CV events were 54.9%, 67.1%, and 56.6% respectively. For CLI patients, independent factors for all-cause mortality were age (odds ratio [OR] 1.03), atrial fibrillation (OR 1.79), albumin (OR 0.62), hematocrit (OR 0.96), body mass index (OR 0.94), C-reactive protein (OR 1.18), dialysis (OR 2.16), and non-ambulance (OR 2.05). Congestive heart failure, dialysis, and non-ambulance independently predicted the MACEs (OR 2.04, 1.93, and 1.67, respectively). For claudicants, coronary artery disease (CAD) was the essential factor for all-cause mortality (OR 2.24), MACE (OR 2.76) and non-fatal CV events (OR 1.82). Conclusion: Long-term survival and MACE-free rates were significantly worse in CLI patients than in claudicants. Malnutrition and inflammation were associated with long-term survival. CAD, low hematocrit, dialysis, CHF, and ambulatory status predicted future CV events.
