While at Albert Einstein College of Medicine in New York, Dr. Lefer and his co-researchers showed that hydrogen sulfide could limit scarring and inflammation in the heart muscles of mice after a simulated heart attack, and that delivering hydrogen sulfide to the liver in a mouse model of liver surgery could reduce damage caused by loss and restoration of blood flow. His Emory-based studies have continued with this focus and found that low concentrations of the toxic gas can protect the hearts of mice from heart failure. In 2010, he was appointed director of Emory's Cardiothoracic Research Laboratory. In the April 2011 edition of Circulation Research, Dr. Lefer and Dr. John Calvert published a study that provided new evidence that nitric oxide generated during physical exercise is stored in the bloodstream and heart in the form of nitrite and nitrosothiols, and that these more stable nitric oxide intermediates appeared to be critical for the cardioprotection against a subsequent heart attack. In November 2011 Dr. Lefer and his Emory team presented a study that concluded that diallyl trisulfide ― a potent-smelling component of garlic oil ― may help release protective compounds to the heart after heart attack, during cardiac surgery, or as a treatment for heart failure.
