Abstract

Objectives: This study sought to assess 2-year clinical outcome following percutaneous coronary intervention (PCI) with thin-strut new-generation drug-eluting stents (DES) in patients treated in proximal left anterior descending artery (P-LAD) versus non–P-LAD lesions. Background: In current revascularization guidelines, P-LAD coronary artery stenosis is discussed separately, mainly because of a higher adverse event risk and benefits of bypass surgery. Methods: The study included 6,037 patients without previous bypass surgery or left main stem involvement from the TWENTE I, II, and III randomized trials. A total of 1,607 (26.6%) patients had at least 1 DES implanted in P-LAD and were compared with 4,430 (73.4%) patients who were exclusively treated in other (non–P-LAD) segments. Results: Two-year follow-up was available in 5,995 (99.3%) patients. At baseline, P-LAD patients had more multivessel treatment and longer total stent length. The rate of the patient-oriented composite clinical endpoint (any death, any myocardial infarction, or any revascularization) was similar in P-LAD versus non–P-LAD patients (11.4% vs. 11.6%; p = 0.87). In P-LAD patients, the rate of the device-oriented composite clinical endpoint (cardiac death, target vessel myocardial infarction, or target lesion revascularization) was higher (7.6% vs. 6.0%; p = 0.020), driven by a higher rate of target vessel myocardial infarction (4.1% vs. 2.6%; p = 0.002). However, multivariate analysis showed no independent association between stenting P-LAD lesions and clinical endpoints. Conclusions: In this patient-level pooled analysis of 3 large-scale contemporary DES trials, treatment of P-LAD lesions was not independently associated with higher 2-year adverse clinical event rates. These results imply that separate consideration in future revascularization guidelines may not be mandatory any longer.
