China PEACE-Prospective 3-vessel Disease Study

Completed

• Conditions: Coronary Heart Disease

• Registration Number: NCT01625312
• Lead Sponsor: China National Center for Cardiovascular Diseases

Brief Summary

Coronary heart disease (CHD) pose a serious health threaten to population. Optimal revascularization strategy in multiple vessel coronary artery disease patients remains a subject of debate between interventional cardiologists and surgeons. Knowledge about the real-life revascularization pattern and outcomes in China is limited. By consecutively recruiting three vessel coronary heart disease patients in 25 geographically representative highest-rank hospitals, this study will examine revascularization strategy, and various real-life factors, that may affect patients lone-term recovery. Practical guidelines, appropriateness criteria and quality evaluative system for revascularization strategy will be established based on the findings, to improve patients outcomes in future finally.

Detailed Description

Cardiovascular disease (CVD) is a major concern in public health globally, as well as in China, and remarkable variations of resources available and health system performance have been noted. Relatively limited information is available about how evidence-based therapies are incorporated appropriately into routine clinical practice. Optimal revascularization strategy in multiple vessel coronary artery disease patients remains a subject of debate between interventional cardiologists and surgeons. Practical and applied knowledge from large unselected population is needed to guide practice and policy for quality improvement and cost reduction.

This study will enroll patients with diagnosis of three-vessel disease, or left main disease with significant lesion (over 50%) consecutively in 25 tertiary hospitals scattered all over China. At study entry, participants will be interviewed during their index hospitalization, to collect information about symptoms, functioning, quality of life, and medical care. Demographic characteristics, medical history, clinical features, diagnostic tests, medications, procedures, and in-hospital outcomes of patients will be abstracted from medical records by well trained professional abstractors. And CAG imaging will be reviewed by national and international expert panels. At 1 month, 6 month, and 12 month after discharge, participants will return to the clinic for follow up visits, a face-to-face interview will be conducted to get information about clinical events, symptoms, functioning, quality of life, and medical care during the recovery period. At 1-Month and 12-Month follow-up visit, blood and urine sample will be collected. Participants' blood samples will be stored for future biologic and genetic studies. This study will examine various real-life factors that may affect multiple vessel coronary heart disease patients recovery after PCI/CABG/medications, including patients' characteristics and treatment measures. Practical guidelines, quality evaluative system, and appropriateness criteria will be established based on the findings, to improve patients outcomes in future finally.
