简要总结
The investigators plan to use retrospective data to assess heart function and structure abnormalities through the use of an approved vasodilating agent for stress cardiac MRI tests. The investigators are interested in how these MRI findings relate to long-term prognosis in people who are at risk for cardiac disease.

结局指标
主要结局
A composite outcome measure consisting of cardiovascular mortality and nonfatal MI after index CMR.
时间窗: target follow up of at least 4 years
"Myocardial infarction" will be defined as hospital admission for acute coronary syndrome (defined by positive serum troponin level with documented electrocardiographic changes, clinical syndrome, or need for percutaneous or surgical revascularization).
次要结局
- A composite outcome measure consisting of cardiovascular mortality, nonfatal MI, hospitalization for unstable angina or congestive heart failure, and late unplanned coronary bypass surgery at at least 6 months after index CMR.(target follow up of at least 4 years)
