Stable is defined as no more than a 100% increase or 50% decrease in dose. These criteria may be waived if a subject is intolerant of ACE-I, ARB, ARNI), MRA, beta-blockers, or SGLT2i, subject is unable to afford these agents, subject has contraindications to these agents, or these agents are not indicated under the Guidelines. Such intolerance, lack of affordability, contraindications, or lack of indications must be documented.
• HFrEF (EF \< 50%): Subject has been on stable medications maximized to the subject's tolerance of ACE-I or ARB or ARNI, MRA, beta-blockers, and SGLT2i as determined by the study investigator for at least 30 days prior to Screening/Enrollment
• HFpEF (EF ≥ 50%): Subject has been on stable medication maximized to the subject's tolerance of SGLT2i as determined by the study investigator for at least 30 days prior to Screening/Enrollment 5. NYHA II Cohort- HF related hospitalization within 6 months (last hospitalization should be 30 days before Screening /Enrollment) 5. NYHA III Cohort -HF related hospitalization within 12 month (last hospitalization should be 30 days before Screening/Enrollment)
• \. Subjects should be on diuretic therapy (≥40 mg\] furosemide or equivalent) for ≥ 1 month at time of Screening
• \. Subjects who are physically able to hold the myCordella™ Patient Reader unit (approximate weight 1.3lb) against the ventral thoracic surface for up to 2 minutes per day while in a seated position, as well as dock and undock the myCordella™ Patient Reader
• \. Subjects with sufficient eyesight, hearing, and mental capacity to respond to the myCordella™ Patient Reader's audio/visual cues and operate the myCordella™ Patient Reader
• \. Subject has sufficient Cellular and/ or Wi- Fi Internet coverage at home
• \. Subject agrees to return to the treating Investigator for all scheduled follow up visits and can return to the hospital for follow up

Exclusion criteria

• ACC/AHA Stage D refractory HF (including a known history of \>24 hours of IV inotropic therapy to support circulation within the past 6 months (other than relation to a procedure))

• Subjects who have had a major cardiovascular (CV) event (e.g., myocardial infarction, stroke) within 3 months of the Screening Visit
• Unrepaired severe valvular disease
• Subjects with significant congenital heart disease that has not been repaired and would prevent implantation of the Cordella PA Sensor or mechanical/tissue right heart valve(s)

• Received or are likely to receive an advanced therapy (e.g., durable mechanical circulatory support or lung or heart transplant) in the next 24 months
• Subjects who are pregnant or breastfeeding
• Subjects who are unwilling or deemed by the Investigator to be unwilling to comply with the study protocol, or subjects with a history of non-compliance
• Severe illness, other than heart disease, which would limit survival to \<2 years
