Heart failure (HF) is a global, public health issue that affects more than 63 million people worldwide; this burden is expected to increase substantially as the population ages. Despite advancements in treatment, a HF diagnosis still leads to significant morbidity and mortality; there is also an immense impact on patients' health-related quality of life (HRQoL). Dapagliflozin was recently granted approval for heart failure by the European Commission, regardless of ejection fraction and whether the patient has diabetes. Real-world observational data are necessary to describe dapagliflozin use in real-world settings in order to assess treatment patterns, HF symptoms and their impact on physical limitation, HRQoL and work productivity, as well as health care utilization of patients treated with dapagliflozin in this setting under local treatment standard conditions in Germany.
