- Abstract
Rozanski et al analyzed data from first MPI studies of 39,515 patients without known coronary artery disease (CAD) performed at Cedars-Sinai Medical Center in Los Angeles, CA from January 1991 till December 2009.[2] Patients with known cardiomyopathies and valve disease were excluded. During this 17 year period the percentage of normal studies increased in all patients from 46.2% to 68.2%, both in patients without known CAD (from 67.8% to 82.0%) and with known CAD (from 25.3% to 37.9%). Results of the first SPECT study done in patients without known CAD (N = 35,894 patients) and with known CAD (N = 19,373 patients) were analyzed separately. The percentage of low risk SPECT studies (SSS = 0-3) increased from 63.9% to 95.6% (!) in patients with no known CAD and from 27.8% to 77.1% in patients with known CAD, with a similar decrease in severely abnormal studies (SSS >= 9) (from 16.1% to 2.2%, and from 47.8% to 14.8%, respectively).
