Projected clinical benefits of dapagliflozin in patients with heart failure with preserved ejection fraction.

Heart failure (HF) with preserved ejection fraction is frequent in clinical practice, particularly in the elderly. In HF with preserved ejection fraction, the heart still pumps a similar proportion of blood, but the heart muscle has become thicker. This means there is less space inside the heart to fill with blood, so too little is pumped out each time. Until very recently, no drugs had been shown to provide significant benefits on the outcome of the condition or the chance of recovery for these patients. Fortunately, recent clinical trials have demonstrated that treatment with drugs called SGLT2 inhibitors (e.g., dapagliflozin) could reduce the chance of being admitted to hospital or dying from HF. We investigated the benefits for patients who took dapagliflozin after being admitted to hospital and had HF with mildly reduced or preserved ejection fraction. We saw substantial benefits in this population.
