  • +1 646 962 4950

Dr. Elshazly joined Weill Cornell Medicine - Qatar (WCM-Q) as an Assistant Professor of Medicine in December 2017. He is a Cardiologist and Cardiac Electrophysiologist.

Dr. Elshazly obtained his medical degree from WCM-Q in 2010 with Honors in Academic Achievement. He completed his residency in Internal Medicine at Johns Hopkins Hospital in Baltimore, MD and his fellowship in Cardiology and Cardiac Electrophysiology at the Cleveland Clinic in Cleveland, OH. He is American Board Certified in Internal Medicine and Cardiology. He is a fellow of the American College of Cardiology and a member of the American Heart Association and European Society of Cardiology. 

Dr. Elshazly is a biotech entrepreneur with particular interest in the intersection between digital health and health care delivery. He recently founded Ember Medical in San Francisco, CA, a biotech startup working on revolutionizing medical emergency response using crowdsourcing technologies in order to save lives and reduce health care costs.

Dr. Elshazly's other research interests include preventive cardiology, precision medicine and atrial fibrillation. He led several studies examining the impact of discordance between lipid parameters on cardiovascular risk assessment and management. He worked with the Johns Hopkins Ciccarone Center for the Prevention of Heart Disease to develop a new equation for estimating LDL cholesterol levels that is becoming the new standard measurement. He continues to lead several research efforts in preventive cardiology and atrial fibrillation.

Dr. Elshazly has authored many research articles in leading cardiology and medicine journals as well as several book chapters in cardiology textbooks. He was awarded the Cleveland Clinic's Tomsich Award and the Lower Clinical Award for excellence in clinical research. He has also received several teaching awards for his efforts in teaching medical students and residents at the Cleveland Clinic.

research overview

  • Dr. Elshazly's research focuses on cardiovascular disease (CVD) risk assessment, prevention and treatment. He has worked with the Ciccarone Center for the Prevention of Heart Disease on several important projects using the Very Large Database of Lipids (VLDL), a sample of 1.3 million lipid profiles. They were able to prove that the commonly used Friedewald equation for estimating LDL cholesterol is inaccurate and they developed a new equation that has become the new standard in lab reports across the nation. Moreover, they showed that discordance exists between LDL levels and levels of other more inclusive markers of “bad” cholesterol such as Non-HDL cholesterol and TC/HDL ratio. These results showed that clinicians ought to be assessing these alternative lipid parameters to optimize CVD risk assessment and treatment. Their work has helped shape some of the new national and international cholesterol guidelines and was highlighted in FDA documents examining the new PCSK-9 inhibitor medications. Dr. Elshazly has also examined the issue of lipid discordance in national cohorts such as ARIC and IVUS trial databases. He is continuing to work on other aspects of CVD prevention using regional and international patient cohorts. 

    Dr. Elshazly is also interested in using cardiopulmonary stress testing to assess the impact of atrial fibrillation on exercise tolerance. With collaborators from the Cleveland Clinic, he was able to show that atrial fibrillation reduces exercise capacity and survival in patients with heart failure with preserved ejection fraction. He continues to examine this issue in other patient cohorts.
