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). On May 5, 2020, the US Food and Drug Administration (FDA) announced the approval of dapagliflozin for heart failure with reduced ejection fraction (HFrEF), regardless of whether the patient has diabetes. Subsequently, there have been additional approvals for this indication by regulatory authorities across the globe." Real-world observational data are necessary to describe dapagliflozin use in real-world settings with detailed clinical data on heart failure symptoms, outcomes, and HRQoL

Inclusion Criteria:

• Age ≥18 years as of study index date; the study index date is date of initiation of treatment with dapagliflozin
• Patient received/receiving treatment with dapagliflozin for HFrEF (EF ≤40%) in accordance with the local dapagliflozin product label
• Signed and dated informed consent prior to enrolment in the study

Exclusion Criteria:

• Patient is enrolled less than 14 days or more than 60 days following initiation of dapagliflozin
• Prior treatment with dapagliflozin or other SGLT2i treatment
• Initiation of dapagliflozin outside of local HF label
• Diagnosis of Type 1 diabetes prior to enrolment

Patients who have received treatment with dapagliflozin for HFrEF will be eligible for enrolment by either primary or secondary care healthcare professionals from both outpatient and inpatient settings. In all cases, the decision to treat a patient with dapagliflozin must be made prior to the decision to enrol the patient into the study. To help ensure this, patients cannot be enrolled <14 days after starting dapagliflozin treatment. Therefore, the earliest date at which all data collected directly from patients such as PROs may be captured is 14 days following initiation of dapagliflozin. Patients may have discontinued from dapagliflozin prior to enrolment onto the study, as long as their dapagliflozin initiation was ≥14 days and ≤60 days prior to enrolment onto the study. Data on other parameters may be obtained at the date of initiation of dapagliflozin by extracting this information retrospectively from medical charts.
