Stress-only or stress/rest myocardial perfusion imaging in patients undergoing evaluation for bariatric surgery
Journal of Nuclear Cardiology, 07/18/2011
Gemignani AS et al. – In a typical pre–bariatric surgery population, the incidence of abnormal stress MPI is low. The majority of patients were able to use a stress–only strategy for assessment of perfusion. At 1 year the incidence of adverse cardiovascular outcomes is very low. Additional studies should be focused on determining whether any subgroup of such patients may benefit more from pre–operative stress testing.
Methods
- Authors retrospectively reviewed a series of 383 consecutive stress MPI studies performed on patients undergoing workup prior to planned bariatric surgery.
- The study population had a mean age 42 ± 10 years, and was 83% female, with a body mass index of 49 ± 8.
Results
- The majority of patients (81%) were able to exercise using either the Bruce or Modified Bruce protocol, and 67% underwent stress–only imaging.
- Overall SPECT MPI findings were ...read more
