To retrieve and analyze the evidence related to perioperative blood glucose management in patients with coronary heart disease (CHD) complicated by diabetes undergoing percutaneous coronary intervention (PCI) , and provide clinical guidance for glucose management.

Systematic searches were conducted on domestic and international guideline websites, evidence-based databases, primary research databases, and related association websites for evidence concerning perioperative blood glucose management for this patient group. The search included clinical decisions, guidelines, expert consensus, evidence summaries, and systematic reviews, covering the time span from database inception to February 2022. Two evidence-trained researchers independently conducted literature quality assessments and evidence extraction, with disputes resolved by a third party.

Eighteen articles were included: one clinical decision, nine guidelines, and eight expert consensuses. The findings were summarized into eight aspects: team formation and training, admission assessment and treatment, blood glucose control targets, preoperative glucose management, intraoperative glucose management, postoperative glucose management, perioperative abnormal glucose management, and discharge management, totaling 35 evidence points.

This study consolidates evidence related to perioperative blood glucose management for patients with CHD complicated by diabetes undergoing PCI. However, during the evidence translation and application process, conditions of the application site, medical resources, and patient preferences should be fully considered. After assessing the feasibility and applicability of the evidence, a personalized blood glucose management plan should be developed for the patient, aiming to improve blood glucose levels and prognosis.
