Cleveland Clinic’s Stanley Hazen, MD, PhD, Named a 2017 AHA Distinguished Scientist

Cleveland Clinic physician and researcher Stanley L. Hazen, MD, PhD, has been named a 2017 Distinguished Scientist by the American Heart Association (AHA), the highest award the AHA bestows for scientific discoveries.

The designation “honors American Heart Association professional members who have made extraordinary contributions to cardiovascular and stroke research,” according to the AHA. The seven 2017 Distinguished Scientists were honored during the opening session of the AHA Scientific Sessions 2017 on Nov. 12.

Dr. Hazen is Chair of the Department of Cellular and Molecular Medicine in Cleveland Clinic’s Lerner Research Institute and Section Head of Preventive Cardiology and Rehabilitation in the Miller Family Heart & Vascular Institute. He has spent his entire professional career at Cleveland Clinic and is the first Cleveland Clinic physician to receive the AHA Distinguished Scientist designation, which the association has been awarding since 2003.

The work behind the honor

In announcing the recognition, the AHA cited Dr. Hazen’s “several pioneering discoveries in atherosclerosis and inflammatory disease research that have impacted clinical practice.” Those discoveries resulted from decades of work in multiple research areas. The announcement specifically referenced Dr. Hazen’s following achievements:

  • Making the seminal discovery linking gut microbial pathways to cardiovascular disease (CVD) pathogenesis and development of heart failure and chronic kidney disease. “His comprehensive work established a paradigm for understanding diet-gut microbiome-host interactions in diseases, and has spawned development of new diagnostic tests and therapeutic approaches to treat and prevent CVD and metabolic disorders,” the association noted in a statement.
  • Defining pathways that leukocytes use to generate reactive oxidants
  • Discovering the functional importance of oxidation processes in CVD, macrophage recognition of senescent and apoptotic cells, modified lipoproteins and in vivo regulation of platelet hyper-responsiveness

“His studies laid the foundation for the development of diagnostic tests for CVD risk assessment that are in use worldwide, and have helped to spawn pharmaceutical development of myeloperoxidase inhibitors that are in clinical trials,” the AHA statement continued.

“I am honored and humbled to receive this recognition,” Dr. Hazen says. “I want to acknowledge and thank my colleagues and many lab members who have helped and supported me in making these discoveries and advances over the years.”


The view from colleagues

“Dr. Hazen’s research has fundamentally changed the way we think about the role of diet and the microbiome in the pathogenesis of heart disease,” says Serpil Erzurum, MD, Chair of Cleveland Clinic’s Lerner Research Institute. “He is highly deserving of this distinguished award. We have already seen how his findings can change care. We look forward to watching his research continue to advance, and to see how his work will impact human health and patient care.”

“Dr. Hazen is one of the most accomplished physician-scientists in America,” notes Steven Nissen, MD, Cleveland Clinic’s Chair of Cardiovascular Medicine. “His landmark research on the role of gut bacteria in cardiovascular disease has led the way forward into an entirely new field of scientific discovery. This award is richly deserved.”

“The groundbreaking research led by Dr. Hazen has uncovered one of the keys to understanding how our diets affect cardiovascular disease risk based on blood sample analysis,” adds Cleveland Clinic Heart & Vascular Institute Chair Lars Svensson, MD, PhD. “This is the type of original research that affects all people and may shape what they eat.”
