Environmental factors for heart failure risk stratification

A method for determining a heart failure (HF) risk score of a patient indicating a probability of occurrence of a heart failure event, the method comprising:

• receiving a plurality of diagnostic parameters of a patient associated with heart failure from an implantable device, wherein at least one of the plurality of diagnostic parameters is measured by and retrieved from the implantable medical device;
• obtaining environmental factor information associated with heart failure for the patient;
• determining a heart failure (HF) risk score indicating probability of occurrence of a heart failure event, wherein the HF risk score is derived using a model that uses the plurality of diagnostic parameters monitored over time and the environmental factor information;
• and
• in response to the HF risk score exceeding a threshold value, providing an alert or a suggestion to modify a therapy delivered to the patient by the implantable medical device.

A system comprising:

• an implantable medical device comprising one or more sensors configured to monitor over time at least one primary diagnostic parameter associated with heart failure;
• and
• an external device interacting with the implantable medical device to obtain the at least one primary diagnostic parameter associated with heart failure;
• and
• a server comprising:
• a processor configured to:
• receive the at least one primary diagnostic parameter from the implantable medical device;
• obtain environmental factor information associated with heart failure for the patient;
• determine a heart failure (HF) risk score indicating probability of occurrence of a heart failure event of the patient, wherein the HF risk score is derived using a model that uses the at least one primary diagnostic parameter monitored over time and the environmental factor information;
• and
• in response to the HF risk score exceeding a threshold value, provide an alert or a suggestion to modify a therapy delivered to the patient by the implantable medical device.
