Abstract
The invention is directed to techniques for monitoring the condition of a patient, such as a patient having congestive heart failure, and appropriately modifying the patient's drug therapy as a function of a pressure in the patient's heart, such as the estimated pulmonary artery diastolic pressure. The drugs may be administered by an implanted drug delivery device. The drug selection, the drug dosage or both may be controlled as a function of the pressure and/or the activity level of the patient.
Claims64
An implantable medical device comprising:
- a pressure monitor that estimates a pulmonary artery diastolic pressure as a function of a pressure in a heart of a patient;
- and
- a processor that selects a dosage that corresponds to the estimated pulmonary artery diastolic pressure.
An implantable medical device comprising:
- a pressure monitor that estimates a pulmonary artery diastolic pressure as a function of a pressure in a heart of a patient;
- and
- a processor that selects a drug that corresponds to the estimated pulmonary artery diastolic pressure.
A method comprising:
- estimating a pulmonary artery diastolic pressure as a function of a pressure in a heart of a patient;
- selecting a drug therapy as a function of the estimated pulmonary artery diastolic pressure;
- and
- controlling a drug delivery device to deliver a drug to the patient as a function of the selected drug therapy.
A computer-readable medium comprising instructions that cause a processor to:
- receive an estimated pulmonary artery diastolic pressure value;
- select a drug therapy as a function of the estimated pulmonary artery diastolic pressure value;
- and
- control a drug delivery device to deliver a drug to a patient as a function of the selected drug therapy.
An implantable medical device comprising:
- means to estimate pulmonary artery diastolic pressure;
- means to select a drug therapy as a function of the estimated pulmonary artery diastolic pressure;
- and
- means to deliver a drug as a function of the selected drug therapy.
