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.
All-cause mortality, MI, heart failure hospitalization or documentation of an LV ejection fraction < 0.40 after index CMR at a follow-up. [ Time Frame: 5 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). "Heart failure hospitalization" will be defined as any hospitalization for signs and symptoms of volume overload or dyspnea requiring diuretic therapy regardless of LV ejection fraction.
