Decision Variability Between Different Heart Teams for Complex Coronary Artery Diseases

Study Overview
=================
Brief Summary
-----------------
The purposes of this study are 1) to explore the variability of decisions between different heart teams in complex coronary artery disease; 2) to evaluate the reasons of the discrepancy in decision making.

Detailed Description
-----------------
Heart team has been recommended by guideline for optimizing the decision making for patients with complex coronary artery diseases (CAD). However, prior studies have demonstrated that heart team decision might have poor reproducibility, and the variability of heart team decision remains unknown. Thus, the investigators designed a single-center, retrospective, cross-sectional study to explore the decision variability of heart team in CAD patients. The investigators will retrospectively recruit patients with angiographically confirmed 3-vessel or left main disease from a coronary angiography database at Fuwai hospital. Patients' baseline information will be collected. And different heart teams will be established and made decisions for the enrolled patients. First, the investigators will assess the decision variability between different heart teams. Secondary, the investigators will evaluate the reason of discrepancy by qualitative and quantitative analysis.
