Methods and apparatus to determine the presence of and track functional chronotropic incompetence (hereinafter “CI”) in an in-home setting under conditions of daily living. The functional CI of the patient may be determined with one or more of a profile of measured patient heart rates, a measured maximum patient heart rate, or a peak of the heart rate profile. The functional CI of the patient may be determined with the measured heart rate profile, in which the measured heart rate profile may correspond to heart rates substantially less than the maximum heart rate of the patient, such that the heart rate can be safely measured when the patient is remote from a health care provider. The functional CI of the patient may be determined based a peak of the remotely measured heart rate profile, for example a peak corresponding to the mode of the heart rate distribution profile.

1. An apparatus to monitor a patient, the apparatus comprising, a processor system comprising at least one processor having a tangible medium with instructions of a computer program embodied thereon, the processor system configured to:receive heart rate data of the patient, the heart rate data comprising a plurality of measurements of the patient's heart rate taken over a period of time by an adherent and/or implantable device associated with the patient without subjecting the patient to a cardiac stress test;construct a heart rate profile based on the plurality of measurements taken over a period of time, wherein a peak of the heart rate profile is selected as representative of the resting heart rate of the patient, the peak of the heart rate profile corresponding with a mode of the plurality of measurements;determine an age-corrected maximum heart rate of the patient based on patient age;determine a heart rate reserve (HRR) based on the age corrected maximum heart rate and resting heart rate of the patient; andcompare the HRR to a threshold value and identify chronotropic incompetence if the HRR is below the threshold. 2. The apparatus of claim 1, wherein the patient is remotely located with respect to a clinic. 3. A method of monitoring a patient to detect chronotropic incompetence, the method comprising: receiving heart rate data of the patient, the heart rate data comprising a plurality of measurements of the patient's heart rate taken over a period of time by an adherent and/or implantable device associated with the patient without subjecting the patient to a cardiac stress test;constructing a heart rate profile based on the plurality of heart rate measurements taken over a period of time, wherein a peak of the heart rate profile is selected as representative of the resting heart rate of the patient, the peak of the heart rate profile corresponding with a mode of the plurality of measurements;determining an age-corrected maximum heart rate of the patient based on patient age;determining a heart rate reserve (HRR) based on the age corrected maximum heart rate and resting heart rate of the patient; andcomparing the HRR to a threshold value and identifying chronotropic incompetence if the HRR is below the threshold. 4. The apparatus of claim 1, wherein the processor system is further configured to: receive activity data of the patient;compare patient activity data to an activity threshold to determine activity above the activity threshold;determine heart rate data corresponding with patient activity data above the activity threshold;determine a maximum heart rate of the patient based on the heart rate data determined to correspond with patient activity data above the activity threshold; andidentify chronotropic incompetence based, at least in part, on a comparison of the maximum heart rate of the patient to a threshold maximum heart rate. 5. The apparatus of claim 4, wherein the processor further comprises instructions to determine a correlation of the maximum heart rate with one or more of the patient activity, patient body posture, patient breath rate or patient respiration rate and wherein the processor system is configured to identify chronotropic incompetence based on the correlation. 6. The apparatus of claim 4, wherein the activity threshold is determined based on a patient data received from a plurality of other patients. 7. The method of claim 3, further comprising: receiving activity data of the patient;comparing patient activity data to an activity threshold to determine activity above the activity threshold;determining heart rate data corresponding with patient activity data above the activity threshold;determining a maximum heart rate of the patient based on the heart rate data determined to correspond with patient activity data above the activity threshold; andidentifying chronotropic incompetence based, at least in part, on a comparison of the maximum heart rate of the patient to a threshold maximum heart rate. 8. The method of claim 7, further comprising determining a correlation of the maximum heart rate with one or more of the patient activity, patient body posture, patient breath rate or patient respiration rate. 9. The method of claim 8, wherein identifying chronotropic incompetence is further based on the correlation. 10. The method of claim 7, wherein the activity threshold is determined based on a patient data received from a plurality of other patients.
