      • Hospitalization with HF as primary cause in last 12 months
      • Structural heart disease on echo according to ESC guidelines i.e. either enlarged Left atrial volume index (LAVI > 34 ml/m2) or increased LVM (LVM index > 95 g/m2 in women and > 115 g/m2 in men)
      • Pulmonary capillary wedge pressure (PCWP) at rest >15 mmHg or >25 mmHg at exercise

8. Male patients must be surgically sterile or using an acceptable method of contraception (defined as barrier methods in conjunction with spermicides) for the duration of the study (from the time they sign consent) and for 3 months after the last dose of AZD4831/matching placebo to prevent pregnancy in a partner. Male patients must not donate or bank sperm during this same time period

Current hemodynamically significant valve disease in opinion of investigator

EF ever documented < 40%

Any current life-threatening dysrhythmia

Probable alternative primary reason for patient's symptoms in judgment of investigator, including but not limited to:
