One-year clinical outcomes in patients with chronic kidney disease treated with COMBO stents: From the COMBO collaboration.

Abstract

BACKGROUND:

Chronic kidney disease (CKD) patients undergoing percutaneous coronary intervention (PCI) experience greater ischemic events including clinically driven target lesion revascularization (CD-TLR). Whether the COMBO biodegradable-polymer sirolimus-eluting stent promotes better outcomes in these patients by virtue of endothelial progenitor cell capture technology is unknown.

OBJECTIVE:

We examined one-year outcomes by CKD status from the COMBO collaboration.

METHODS:

The COMBO collaboration was a patient-level pooled dataset from the REMEDEE and MASCOT registries (3,614 patients) of all-comers undergoing attempted COMBO stent PCI. The primary endpoint was one-year target lesion failure (TLF), composite of cardiac death, target-vessel myocardial infarction (TV-MI) or CD-TLR. Secondary endpoints included stent thrombosis (ST).

RESULTS:

The study included 6.4% (n = 231) CKD and 93.6% (n = 3,361) non-CKD patients. CKD patients were older and included more women with greater prevalence of several comorbidities but similar rate of acute coronary syndrome (50.6% vs. 54.5%, p = .26). CKD patients underwent radial PCI less often (56.1% vs. 70.3%, p < .001) and received clopidogrel (78.6% vs. 68.3%) more often (p = .004). One-year TLF occurred in 7.9% CKD vs. 3.7% non-CKD patients, p = .001. CKD patients also demonstrated greater incidence of cardiac death (6.2% vs. 1.2%, p < .0001), TV-MI (2.7% vs. 1.1%, p = .04) but similar CD-TLR (2.7% vs 2.2%, p = .61) and definite/probable ST (1.4% vs. 0.8%, p = .42), compared to non-CKD patients.

CONCLUSIONS:

CKD patients treated with COMBO stents had significantly greater incidence of one-year TLF compared to non-CKD patients driven by cardiac death and to a lesser extent TV-MI but not CD-TLR. They had similar rates of definite/probable ST.
