Safety and Efficacy of Low Temperature Contrast in UAP Patients During PCI (LOTA-I) — LOTA-I  

Unstable Angina Pectoris Clinical Trial

Official title:
Safety and Efficacy of Low Temperature Contrast for the Treatment of PCI-related Myocardial Injury in Patients With Unstable Angina Pectoris (LOTA-I)

Clinical Trial Summary

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.

Clinical Trial Description

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. ;
