Abstract
PurposeTo evaluate the all-cause mortality after treatment with paclitaxel-coated devices depending on paclitaxel exposure in real-world practice. Materials and MethodsA retrospective analysis of mortality of patients with at least a 3-year follow-up was performed. Patients were categorized into terciles according to the paclitaxel dosage received during the index procedure and every subsequent intervention. The incidence of mortality of these patients was compared with that of a paclitaxel-naïve control group. ResultsIn total, 2,376 patients were treated with drug-coated devices and 980 patients with uncoated devices. The overall all-cause mortality rate at a mean follow-up of 46.27 months ± 24.71 was 29.2% (n = 696) for the paclitaxel group and 49.4% (n = 484) for the paclitaxel-naive control group. The mortality rate between the groups according to the initial paclitaxel exposure was not significantly different (P = .205). In comparison to the group of surviving patients, the total lifetime paclitaxel dosage was lower in the group of patients who died (P < .001). ConclusionsIn this real-world retrospective analysis, long-term mortality was not correlated with the paclitaxel exposure during the index procedure. Regarding the total paclitaxel exposure, lower mortality was observed in the highest tercile of paclitaxel exposure.
