Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

N Terminal (NT)-Pro b-type natriuretic peptide (BNP) levels provide incremental value in perioperative risk assessment prior to major non-cardiac surgery. The investigators will test whether pharmacologically lowering this biomarker with daily administration of CoQ10 for 3 days prior to elective vascular surgery will reduce adverse outcomes following the operation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients will be screened during their preoperative evaluation. Inclusion criteria include patients in need of an elective vascular operation. Exclusion criteria include urgent operation, known allergic reactions to CoQ10 and participation in another research study. Suitable participants will be randomly assigned to receive either CoQ10 (400 mg per day) versus Placebo for 3 days prior to surgery. A randomized, double blind trial will be used and a research pharmacist will guide the randomization process, blinded to clinical information. The primary end-point measures are BNP levels at 24 and 48 hours following the operation as well as the incidence of myocardial injury, defined by an elevated post-operative high-sensitivity troponin following high risk surgery. Secondary outcome measures include the magnitude of the troponin level, which is the change in the level compared with preoperative baseline troponin levels and adverse clinical cardiac outcomes during the hospitalization period, including death, non-fatal myocardial infarction, diagnosed by a cardiologist who is blinded to the treatment strategy and any coronary artery revascularization procedure. The study will be focused on 30-days following the vascular procedure but the investigators may plan to extend secondary outcome measures for 1 year post-randomization.
