Complex Coronary Artery Disease

Brief summary

COMPLEX Registry is an investigator-initiated, retrospective, high-volume Polish single-center clinical registry enrolling 980 consecutive patients with complex coronary artery lesions treated percutaneously between September 2015 and December 2021. All data were collected prospectively as regards the clinical and technical endpoints. The study aimed to assess the safety and efficacy of new-generation, thin-struts DES in patients with complex CAD at long-term clinical follow-up. The primary endpoint of the study was the occurrence of TLR during follow-up. Secondary endpoints were a procedural success and the occurrence of MACE, including all-cause death, MI, or TLR.

Interventions

PROCEDUREPercutaneous coronary intervention (PCI) with drug-eluting stent (DES) implantation

PCI was performed according to the general and local recommendations. The choice of DES among the new generation DES and the decision on procedure optimization belonged to the operator.

Inclusion criteria

* For the inclusion of patients in this study, the complexity of CAD was defined as having at least one of the following characteristics: chronic total occlusion (CTO), lesion length \>40 mm, severe calcification assessed by angiography or intravascular imaging examination, multivessel PCI during the same intervention, or true bifurcation defined as any lesion involving both the main vessel (MV), proximal or distal and the ostium of the side branch (SB) (Medina 1,1,1; 1,0,1; or 0,1,1).

Exclusion criteria

* left main stem * PCI treated during index procedure; * cardiogenic shock, * thrombolysis before PCI; * 12-month follow-up not available

Design outcomes

Primary

MeasureTime frameDescription
Target lesion revascularization (TLR)12 monthsDuring the 12-month follow-up, the incidence of TLR in patients included in the study will be reported. TLR was defined as revascularization post-stenting within the stent or within the 5-mm borders adjacent to the stent.

Secondary

MeasureTime frameDescription
Major adverse cardiac events (MACE)12 monthDuring the 12-month follow-up, the incidence of MACE in patients included in the study will be assessed. Major adverse cardiac event composed of all-cause death, myocardial infarction (MI), or TLR.
Procedural successPeri-proceduralProcedural success was defined as angiographic success in the absence of in-hospital major events including death, MI, need for TLR, stroke, vascular access site complications, and contrast agent nephropathy.
