Association Between Time in Range and In-hospital Outcomes in Type 2 Diabetic Patients With Acute Coronary Syndrome

Not Applicable

• Conditions: Acute Coronary Syndrome; Type 2 Diabetes Mellitus
• Interventions: Device: capillary blood glucose monitoring; Device: continuous glucose monitoring system

• Registration Number: NCT05389254
• Lead Sponsor: Ningbo No. 1 Hospital

Brief Summary

The aim of this study is to use real-time continuous glucose monitoring (real-time CGM) system to get a 14-days blood glucose profile of the hospitalized type 2 diabetes mellitus (T2DM) patients with acute coronary syndrome (ACS), and to understand whether time in range (TIR) is associated with in-hospital outcomes of these patients. This study plans to recruit 100 patients. They will be randomly divided into 2 groups: real-time CGM group and capillary blood glucose monitoring group. All enrolled participants will receive standardized blood glucose management according to the "Expert consensus on blood glucose management of inpatients in China". The duration of the study will be 3 months. The primary endpoint is the average hospital stay and cardiac care unit (CCU) occupancy rate in T2DM patients with ACS. The secondary endpoint is a composite endpoint of nonfatal myocardial infarction, acute heart failure, heart failure rehospitalization, coronary revascularization, cardiovascular death, all-cause death.

Arm && Interventions

Group	Intervention	Description
Capillary blood glucose monitoring group	capillary blood glucose monitoring	Participants in this group will be implanted with sensors of SISENSING® GS1 continuous glucose monitoring system in their left upper arm within 24 hours after hospitalization. But these patients will be blind to the CGM data. They'll receive 8-point capillary blood glucose monitoring simultaneously, which are 6am, 9am, 11am, 1pm, 4pm, 7pm, 9pm, 2am. According to the 8-point glucose data and clinical needs, researchers will carry out individualized in-hospital blood glucose standard management.
