A medication originally used for patients with diabetes is the first to help people with heart failure (HF) and could revolutionize treatment, according to new research from the University of East Anglia (UEA) in the U.K. Early research had shown that sodium-glucose cotransporter-2 (SGLT2) inhibitors could help about half of HF patients—those with a condition known as reduced ejection fraction.
New findings indicate that the medication could be beneficial for all HF patients, including those with a second type of HF called preserved ejection fraction. It is the first drug to provide a real benefit in terms of improving outcomes for these patients. And the research team say it will revolutionize treatment options.
Lead researcher Professor Vass Vassiliou, from UEA’s Norwich Medical School and an Honorary Consultant Cardiologist at the Norfolk and Norwich University Hospital, said, “Heart failure is a condition where the heart is not pumping as well as it should, and it affects about one million people in the U.K.
“There are two types of heart failure. Heart failure with a reduction in ejection fraction happens when the heart is unable to pump blood round the body due to a mechanical issue. And heart failure with preserved ejection fraction happens when despite the heart pumping out blood well, it is not sufficient to provide oxygen to all the parts of the body. Patients are equally split between the two types of heart failure.”
For many years, Dr. Vassiliou said, there were no medicines that could improve the outcome in patients with the second type of HF—preserved ejection fraction.
“This type of heart failure had puzzled doctors, as every medicine tested showed no benefit,” he added.
One class of heart medication, SGLT2 inhibitors, was initially used for patients with diabetes. However, Dr. Vassiliou added, scientists observed that it also helped patients who had HF.
SGLT2 inhibitors are more commonly known under their trade-names Forxiga (dapagliflozin), Invokana (canagliflozin), and Jardiance (empagliflozin). The research team undertook a meta-analysis of all studies published in the field and brought together data from almost 10,000 patients. They used statistical modeling to show the specific effect of these medicines.
Dr. Vassiliou said, “We found that patients taking SGLT2 inhibitors were 22% less likely to die from heart-related causes or be hospitalized for heart failure exacerbation than those taking placebo.”
This is very important, he added, because this was the first medication to provide a benefit to this previously untreatable group of patients.
“This is the first medication that can really improve the outcomes for this patient group, and it will revolutionize the treatment offered to heart failure patients,” he concluded.
