Brief Summary

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

Percutaneous coronary intervention (PCI) has become one of the main treatments for rapid recovery of revascularization in patients with coronary heart disease (CHD). PCI has some advantages, such as easy operation, small trauma and rapid recovery. It can significantly improve myocardial ischemic symptom and reduce the incidence of cardiovascular adverse events in CHD patients. However, many studies have found that the incidence of PCI-related myocardial injury is relatively high, and affect the efficacy of PCI and prognosis in patients with unstable angina pectoris (UAP). A meta-analysis of a total of 7578 patients with UAP from 15 studies who underwent PCI was found to have a 28.7% increase in myocardial biomarkers after PCI. The objective of this randomized control trial is to gain a clinical insight on the use of low temperature contrast for the treatment of PCI-related myocardial injury in UAP patients. The primary objective is assess efficacy and safety of low temperature contrast for the treatment of PCI-related myocardial injury in UAP patients.

Detailed Description

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

The current study is designed as a multicenter, randomized and prospective study aiming to compare the change in levels of myocardial injury biomarkers (such as TNI and CK-MB) between low temperature contrast group and room temperature contrast group. Based on previous study, the incidence rate of PCI-related myocardial injury is 28.7% in UAP patients undergoing PCI. And in our study the expected incidence rate of PCI-related myocardial injury is up to 14.3% in UAP patients undergoing PCI after treatment with low temperature contrast. Moreover, the investigators estimated 10% loss follow-up of these patients in each arm. As a result, a total of 440 UAP patients were required, and with 220 patients per group as a ratio of 1:1 randomization.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

low temperature contrast

A total of 220 patients are assigned to low temperature contrast group after randomization schedule.

Group Type EXPERIMENTAL

low temperature contrast

Intervention Type OTHER

UAP patients undergoing PCI were performed with low temperature contrast. The investigators used thermal insulation equipment to keep contrast at 5℃. The EKG and blood pressure were monitored during the PCI procedure. After PCI, the investigators monitored levels of myocardial injury biomarkers for 3 days every 8 hours.

room temperature contrast

A total of 220 patients are assigned to room temperature contrast group after randomization schedule.

Group Type NO_INTERVENTION
