Real World Effectiveness of the Cordella Pulmonary Artery Sensor System in Patients With Chronic Heart Heart Failure

The study will compare two groups of patients with chronic heart failure:

• One group will use the Cordella PA Sensor System, which monitors heart pressure from home
• The other group will receive standard heart failure medications without a pressure monitoring system

The main goal is to see if patients using the Cordella system have fewer heart failure-related hospital stays and a lower death rate over a two-year period. The study will look especially closely at results for:

• Men and women separately
• Patients with different types of heart failure (preserved or reduced heart function)
• Patients aged 75 and older
• Different racial and ethnic groups
• Patients with kidney disease
• Patients with existing heart devices

The study will use real-world data from:

• Patients using the Cordella system in routine medical care
• Similar patients receiving standard care, identified through medical records and insurance claims Both groups of patients will be carefully matched to ensure they are similar in age, gender, and other important factors that could affect the results.
