Two-Year Outcome Events in Patients With Abnormal MPS Randomized to the Invasive Versus Medical Strategy

Medical Strategy

Invasive Strategy
(n = 43)
HR/OR (95% CI)p Value
Patients with MACE6 (15.4)2 (4.7)0.36 (0.05–1.81)0.215
Cardiac death2 (4.7)0 (0.0)0.91 (0–N.A.)0.999
Myocardial infarction1 (2.6)2 (4.7)1.88 (0.17–20.74)0.607
Revascularization6 (15.4)0 (0.0)0.00 (0–inf)0.998
Scintigraphic ischemia/new scar19 (54.3)6 (15.8)0.16 (0.05–0.45)<0.001
Patients with “overt or silent CAD progression”20 (57.1)6 (15.8)0.14 (0.04–0.40)<0.001

Values are n (%).

CAD = coronary artery disease; CI = confidence interval; HR = hazard ratio; inf = infinity; MACE = major acute cardiac events; MPS = myocardial perfusion single-photon emission computed tomography; N.A. = not applicable; OR = odds ratio.

  • p values from Cox proportional-hazards survival model (HR and 95% CI) except for scintigraphic ischemia or new scar and “overt or silent CAD progression” (OR and 95% CI from generalized linear model).
