Central Venous Pressure and Clinical Outcomes During Left-Sided Mechanical Support for Acute Myocardial Infarction and Cardiogenic Shock.


Background: Right ventricular failure (RVF) is associated with increased mortality among patients receiving left ventricular mechanical circulatory support (LV-MCS) for cardiogenic shock and requires prompt recognition and management. Increased central venous pressure (CVP) is an indicator of potential RVF. Objectives: We studied whether elevated CVP during LV-MCS for acute myocardial infarction complicated by cardiogenic shock is associated with higher mortality. Methods: Between January 2014 and June 2019, we analyzed hemodynamic parameters during Impella LV-MCS from 28 centers in the United States participating in the global, prospective catheter-based ventricular assist device (cVAD) study. A total of 132 patients with a documented CVP measurement while on Impella left-sided support for cardiogenic shock were identified. Results: CVP was significantly higher among patients who died in the hospital (14.0 vs. 11.7 mmHg, p = 0.014), and a CVP >12 identified patients at significantly higher risk for in-hospital mortality (65 vs. 45%, p = 0.02). CVP remained significantly associated with in-hospital mortality even after adjustment in a multivariable model (adjusted OR 1.10 [95% CI 1.02-1.19] per 1 mmHg increase). LV-MCS suction events were non-significantly more frequent among patients with high vs. low CVP (62.11 vs. 7.14 events, p = 0.067). Conclusion: CVP is a single, readily accessible hemodynamic parameter which predicts a higher rate of short-term mortality and may identify subclinical RVF in patients receiving LV-MCS for cardiogenic shock.

Erik Magnus Ohman

Professor of Medicine

Dr. Ohman, Professor of Medicine, received medical degrees from the Royal College of Surgeons in Ireland and the National University of Ireland (1984, Fellowship 1984-1987), and completed his training in cardiology at Duke University (1987-1991), where he has remained on faculty. In 2001, he became Chief of Cardiology at the University of North Carolina at Chapel Hill, where he founded the UNC Heart Center and became its first director. In 2005 he returned to Duke to pursue his interest in advanced coronary disease as the Director of the Program for Advanced Coronary Disease. Since that time, he has been appointed to Associate Director of the Duke Heart Center, the Kent and Siri Rawson Director for the Program for Advanced Coronary Disease, and most recently, Vice-Chair of Development and Innovation in the Department of Medicine.

Dr. Ohman’s clinical and research interests include interventional cardiology and high-risk supported PCI, and treatment of patients with advanced/complex coronary disease. He has researched how to improve patient care through the use of guidelines-based therapies and adherence, and examining global cardiovascular risk and health. He has been a participant on numerous guidelines writing committees, served on the ACC/AHA oversight committee for guidelines development, and has served on the steering committees for trials on ST-elevation myocardial infarction and non-ST-elevation ACS. He is a consultant to the National Institutes of Health, and a consultant for the FDA Advisory Panel for Cardiovascular Devices. 

Dr. Ohman has published over 600 peer-reviewed papers and three books in cardiovascular medicine. He holds three U.S. patents in reperfusion therapy. He is an associate editor for the American Heart Journal and serves on the editorial boards of the Journal of the American College of Cardiology and the American Journal of Cardiology.  He is a Fellow of the Royal College of Physicians in Ireland, the Royal Society of Medicine (U.K.), the European Society of Cardiology, the Society of Cardiac Angiography and Interventions, and the American College of Cardiology.
