Abstract

Background We retrospectively identified heart failure patients with suspected ischemic heart disease who underwent myocardial perfusion imaging (MPI) to examine the relationship of MPI findings to subsequent patient outcomes. Methods The study group consisted of 336 patients with heart failure, left ventricular ejection fraction <45%, and suspected ischemic heart disease who underwent MPI during the period of January 1991 to December 31, 1997. Patients were divided in 3 subgroups: group A (n = 137), large fixed perfusion defects; group B (n = 77), large reversible perfusion defects; and group C (n=122), absence of a large reversible or fixed perfusion defect. Results Overall, the 5-year mortality rate was high at 49.2% ± 3.1%. Mortality was significantly different (P = .009) among the 3 subgroups. Groups A and B had a similar 5-year mortality rates >50%. Group C had a relatively better, but still substantial 5-year mortality rate of 40%. The overall revascularization rate was low (9.7% in 5 years). Conclusion These results indicate a high 5-year mortality rate in patients with large myocardial perfusion defects (fixed or reversible) and presumably an ischemic etiology for their heart failure. Patients with no large or absent perfusion defects had more favorable survival outcomes.
