Figure 3 Adjusted risk of recurrent cardiac admissions at invasive (vs. non-invasive) hospitals. All models have been adjusted for sociodemographic characteristics, clinical severity, attending physician specialty, and hospital academic affiliation, using Cox proportional hazards. These models adjusted for variations in the use of medical therapies and pertain to patients 65 years of age and older. Medications include the use of aspirin, beta-blockers, angiotensin-converting enzyme inhibitors, HMG-CoA reductase inhibitors, and the absence of calcium-channel blockers at hospital discharge.
