The dramatic reduction in cardiovascular death and heart failure hospitalization seen during treatment with empagliflozin (Jardiance) in the EMPA-REG OUTCOME (Empagliflozin Cardiovascular Outcome Event Trial in Type 2 Diabetes Mellitus Patients) trial, for example, has prompted some cardiologists in the year since the first EMPA-REG report to become active prescribers of the drug to their patients who have type 2 diabetes and cardiovascular disease. The same evidence has driven other cardiologists who may not feel fully comfortable prescribing an antidiabetic drug on their own to enter into active partnerships with endocrinologists to work as a team to put diabetes patients with cardiovascular disease on empagliflozin.

In Dr. Fitchett’s practice, “if a patient with type 2 diabetes has an endocrinologist, then I will send a letter to that physician saying I think the patient should be on one of these drugs,” empagliflozin or liraglutide, he said. “If the patient is being treated by a primary care physician, then I will prescribe empagliflozin myself because most primary care physicians are not willing to prescribe it. I think more and more cardiologists are doing this. The great thing about empagliflozin and liraglutide is that they do not cause hypoglycemia and the adverse effect profiles are relatively good. As long as drug cost is not an issue, then as cardiologists we need to adjust glycemia control with cardiovascular benefit as we did years ago with statin treatment,” explained Dr. Fitchett, a cardiologist at St. Michael’s Hospital in Toronto and a senior collaborator and coauthor on the EMPA-REG study.
When results from the 4S [Scandinavian Simvastatin Survival Study] came out in 1994, proving that long-term statin treatment was both safe and increased survival in patients with coronary heart disease, “cardiologists took over lipid management from endocrinologists,” he recalled. “We now have a safe and simple treatment for glucose lowering that also cuts cardiovascular disease events, so cardiologists have to also be involved, at least to some extent. Their degree of involvement depends on their practice and who provides a patient’s primary diabetes care,” he said.
Cardiologists vary on empagliflozin
Other cardiologists are mixed in their take on personally prescribing antidiabetic drugs to high-risk patients with type 2 diabetes. Greg C. Fonarow, MD, has also aggressively taken to empagliflozin over the past year, especially for his patients with heart failure or at high risk for developing heart failure. The EMPA-REG results showed that empagliflozin’s potent impact on reducing cardiovascular death in patients linked closely with a reduction in heart failure hospitalizations. In his recent experience, endocrinologists as well as other physicians who care for patients with type 2 diabetes “are often reluctant to make any changes [in a patient’s hypoglycemic regimen], and in general they have not gravitated toward the treatments that have been shown to improve cardiovascular outcomes and instead focus solely on a patient’s hemoglobin A1c,” Dr. Fonarow said in an interview at the recent annual meeting of the Heart Failure Society of America.
