Disclosures
• Funding Support
– GlaxoSmithKline funded the OPTIMIZE-HF registry
under the guidance of the OPTIMIZE-HF Steering
Committee and funded data collection and
management by Outcome Sciences, Inc (Cambridge,
MA) and analysis of registry data at Duke Clinical
Research Institute (Durham, NC)
• Individual author disclosures are listed in the
manuscript
Fonarow GC, et al. J Am Coll Cardiol. 2007;50:768777.

Heart Failure and Preserved
Systolic Function
• A substantial portion of patients with heart failure
(HF) have relatively normal or preserved systolic
function (PSF)
• Heart failure with PSF has been defined as the
presence of HF symptoms in patients with a
documented left ventricular ejection fraction (EF)
of >40% or >50%, depending on the study
• Few data are available in patients with HF and
PSF that describe outcomes or guide
management strategies
Fonarow GC, et al. J Am Coll Cardiol. 2007;50:768777.
4
Study Objective
• The objective of this study was to evaluate
the characteristics, treatments, and outcomes
of patients with preserved and reduced
systolic function heart failure in a large,
representative population of patients from all
regions of the country.
Fonarow GC, et al. J Am Coll Cardiol. 2007;50:768777.

OPTIMIZE-HF Program Objectives
• OPTIMIZE-HF is a national performance improvement
initiative to improve guidelines adherence in patients
hospitalized with HF
• Overall OPTIMIZE-HF program objectives:
– Improve medical care and education of patients
hospitalized with HF
– Accelerate initiation of HF evidence-based, guidelinerecommended therapies by starting these therapies
before hospital discharge in appropriate patients
without contraindications
– Increase understanding of barriers to use of
ACEIs, -blockers, and other guideline-recommended
therapies in eligible HF patients
Fonarow GC, et al. J Am Coll Cardiol. 2007;50:768777.
6
OPTIMIZE-HF Process-of-Care
Intervention and Registry
• “Process-of-care” intervention
– Enhanced inpatient HF care and education
– Enhanced discharge planning
– Care maps, pathways, and standardized order sets that
encouraged adoption of evidence-based therapies
• ACEI and -blocker initiation before discharge
• JCAHO performance indicators
– Educational programs to encourage adoption by providers
• Web-based registry
– Tracks treatment rates and changes following
performance interventions
– Captures JCAHO/ORYX Quality of Care indicators
– Benchmarks comparisons between institutions
– Enhances understanding of barriers to uptake
Fonarow GC, et al. J Am Coll Cardiol. 2007;50:768777.

OPTIMIZE-HF Performance
Improvement Registry Protocol
• Eligibility
– Adults hospitalized for episode of new or worsening HF as primary
cause of admission, or with significant HF symptoms that develop
during hospitalization when the initial reason for admission was
not HF
– Includes patients with systolic dysfunction and/or isolated diastolic
dysfunction (HF with preserved systolic function)
– Any admission satisfying JCAHO HF core measure criteria
• Prespecified subgroup (10%) with 60–90-day follow-up data
– Survival, readmissions, and medical regimen
– Informed consent required for follow-up
• The registry coordinating center was Outcome Sciences, Inc

Limitations
• The present observations include only hospitalized
patients with HF, a population known to be at increased
risk of adverse outcomes
• Left ventricular function was not assessed in 7,345
patients (15%), and these patients were excluded
• Follow-up data were collected only from a pre-specified
subset of patients and extended only 60 to 90 days after
hospital discharge
• Despite extensive covariate and propensity adjustment,
residual confounding cannot be excluded, thus may only
be demonstrating associations, rather than cause-andeffect relationships
Fonarow GC, et al. J Am Coll Cardiol. 2007;50:768777.
21
Conclusions
• Data from the OPTIMIZE-HF reveal a high prevalence of
HF with PSF
• These patients have a similar post-discharge mortality risk
and equally high rates of rehospitalization as patients with
HF and LVSD
• No differences in clinical outcomes were seen with
different definitions for PSF
• Despite the burden to patients and health care systems,
data are lacking on effective management strategies for
patients with HF and PSF
• Large well designed clinical trials are critically needed to
identify effective management strategies for this
population
