CLINICAL COORDINATING CENTER FOR ACIP

点击翻译按钮获取中文摘要

The purpose of this program is to conduct a multicenter trial as a pilot study to assess the feasibility of and test the methodology required for a full scale clinical trial of asymptomatic cardiac ischemia therapies. The primary objective is to determine the relative efficacy of usual care, stepped medical therapy, and mechanical revascularization to provide freedom from myocardial ischemia. Other objectives are to confirm the frequency of asymptomatic cardiac ischemia in the target patient subgroups, validate current detection and monitoring systems, and clarify other issues important for a full scale clinical trial, such as the availability of patients for randomization and compliance with assigned prescription. The study population will consist of a total of 600 patients with coronary artery disease (CAD), documented by angiographic and radionuclide studies, who have been identified by both exercise stress testing and 48 hour ambulatory ECG monitoring: 300 patients with CAD and exertional angina and 300 patients with asymptomatic CAD. Within each stratum, patients will be randomized to three treatment strategies: usual, symptom-guided care; maximal medical, ambulatory ECG-directed, stepped care therapy; and mechanical revascularization. The primary endpoint will be a reduction of total and asymptomatic cardiac ischemia detected by ambulatory ECG monitoring. This contract is for a Clinical Coordinating Center for coordinating all data collection, storage of data, analysis related to the study, and organizing the steering committee meetings.
