Dr. Engler’s clinical nursing experience included critical care and cardiovascular surgery at Suburban Hospital, Bethesda, Maryland, and the National Heart, Lung, and Blood Institute (NHLBI) at the National Institutes of Health. While at UCSF, Dr. Engler was awarded two NINR Career Development Awards, including an R-29 First Award (Omega-3 Fatty Acids and Cardiovascular Risk Factors) and a K01 Mentored Research Scientist Development Award (Phospholipid Transfer Protein Mutations in Dyslipidemias).
Notably, Dr. Engler led studies on the vascular effects of omega-3 fatty acids from fish and fish oil and the specific biological mechanisms of their vasodilation effect. She was the first to demonstrate the vascular effects of the omega-3 fatty acid, docosahexaenoic acid, in an experimental model, which stemmed from her doctoral dissertation research at Georgetown University and the NIH. This discovery and the subsequent isolated vessel studies set the groundwork for later clinical trials, which demonstrated the cardioprotective effects of the omega-3 fatty acids. Her genetics training led her to examine the genetic factors that contribute to low levels of high-density lipoprotein (HDL) cholesterol (the “good” cholesterol) and heart disease.
Collaborative research with her sister, Dr. Marguerite M. Engler, included the Endothelial Assessment of Risk in Lipids from Youth (EARLY) and EARLY Medit trials that investigated the effects of diet (low fat/cholesterol, Mediterranean) and nutritional supplements on the cardiovascular health of children and adolescents with high cholesterol. Dr. Engler also conducted the first highly publicized clinical trial on the vascular benefits of flavonoid-rich dark chocolate. Her expertise has led to recent appointments on several American Heart Association Writing Groups for position papers on omega-6 and omega-3 fatty acids and genetics. Notably, she has received professional recognition as a Fellow in several specialty areas of the American Heart Association and has been a member in multiple professional physiology, nursing, genetics, cardiovascular, and nutrition organizations.
Dr. Engler’s primary research focus is on nutritional interventions and vascular biology in the prevention and treatment of cardiovascular disease. Specifically, healthy dietary factors or nutrients that may improve vascular health and that lower the risk for developing cardiovascular disease are investigated. These studies examine the effects of certain flavonoids, found in fruits and vegetables, on vascular endothelial function, arterial stiffness, oxidative stress, inflammatory and vascular biomarkers, blood lipid profiles, and blood pressure. As genetic variations and expression of proteins may influence how an individual reacts to dietary therapies, Dr. Engler also analyzes genomic and proteomic profiles in the effort to develop and promote personalized nutrition programs that decrease endothelial dysfunction and increase nitric oxide, thus improving cardiovascular health and preventing disease.
