Percutaneous coronary intervention outcomes in patients with stable coronary disease and left ventricular systolic dysfunction.


AIMS:We sought to better understand the role of percutaneous coronary intervention (PCI) in patients with stable coronary artery disease (CAD) and moderate or severe left ventricular systolic dysfunction. METHODS AND RESULTS:Using data from the Duke Databank for Cardiovascular Disease, we analysed patients who underwent coronary angiography at Duke University Medical Center (1995-2012) that had stable CAD amenable to PCI and left ventricular ejection fraction ≤35%. Patients with acute coronary syndrome or Canadian Cardiovascular Society class III or IV angina were excluded. We used propensity-matched Cox proportional hazards to evaluate the association of PCI with mortality and hospitalizations. Of 901 patients, 259 were treated with PCI and 642 with medical therapy. PCI propensity scores created from 24 variables were used to assemble a matched cohort of 444 patients (222 pairs) receiving PCI or medical therapy alone. Over a median follow-up of 7 years, 128 (58%) PCI and 125 (56%) medical therapy alone patients died [hazard ratio 0.87 (95% confidence interval 0.68, 1.10)]; there was also no difference in the rate of a composite endpoint of all-cause mortality or cardiovascular hospitalization [hazard ratio 1.18 (95% confidence interval 0.96, 1.44)] between the two groups. CONCLUSIONS:In this well-profiled, propensity-matched cohort of patients with stable CAD amenable to PCI and moderate or severe left ventricular systolic dysfunction, the addition of PCI to medical therapy did not improve long-term mortality, or the composite of mortality or cardiovascular hospitalization. The impact of PCI on other outcomes in these high-risk patients requires further study.

Adam D. DeVore, MD, MHS

Dr. DeVore is a cardiologist and Associate Professor of Medicine in the Department of Medicine, Division of Cardiology, at Duke University School of Medicine. His clinical interests include caring for patients and families with heart failure, including those with left ventricular assist devices and heart transplants. He is involved in and leads multiple large studies of patients with heart failure at both Duke University Medical Center and the Duke Clinical Research Institute. He currently serves as the medical director of the Duke Heart Transplant program.

He attended medical school at the University of Chicago Pritzker School of Medicine and completed internal medicine residency at Brigham and Women’s Hospital. He then pursued cardiology training at Duke University and solidified his interests in clinical research and heart failure. He completed a research fellowship at the Duke Clinical Research Institute and a Masters of Health Sciences in Clinical Research before completing an advanced heart failure fellowship at Duke University.

The overarching goals of his research are to advance the current understanding of heart failure through clinical trials as well as develop an evidence base for implementation strategies that addresses the gap between heart failure trial results and clinical practice. For example, he has served on the Steering Committees for large clinical trials, including PIONEER-HF and SPIRRIT-HFpEF. Dr. DeVore also published the first clinical trial conducted within the American Heart Association’s Get With The Guidelines-Heart Failure program, a registry-based cluster randomized trial of quality improvement interventions. He was also the principal investigator for CONNECT-HF, a large-scale, pragmatic, cluster-randomized trial at 161 sites in the US evaluating heart failure quality improvement initiatives. Outside of his work on heart failure, Dr. DeVore is  married with 4 children and spends his time corralling them all and coaching youth baseball.

I am striving to become a clinical and research leader in structural heart disease and complex coronary disease, specifically in the use of antithrombotic agents after structural heart interventions.  I will also explore the significance of bleeding/vascular complications and stroke in these patients as well as potential therapies such as transfusion, and embolic protection devices.


Karen Chiswell

Statistical Scientist

Ph.D., North Carolina State University - 2007

I work closely with clinical and quantitative colleagues to provide statistical leadership, guidance and mentoring on the design, execution, and analysis of clinical research studies. My work includes design and analysis of observational studies (including large cardiovascular registries, and clinical care databases linked with electronic health record data) and early-phase trials in pediatric populations. My statistical interests include study design, linear and non-linear mixed effects models, survival analysis, biology- and mechanism-based models, and statistical thinking and learning.
