Abstract
Medical methods and systems relating to cardiovascular risk and/or performance assessment are provided. An individual performs a programmed activity of daily living such as reading displayed information aloud. The reading aloud is a temporary micro physiological challenge to the individual. The intensity of the micro challenges is gently increased over a short session. The cardiovascular (CV) response of the individual is measured during the session and is analyzed to assess a CV risk or performance of the individual. The existence of subtle CV deviations identified in the CV response of the individual may indicate a CV risk.
Claims20
A method of assessing health performance of a human, the method comprising:
- displaying sets of information sequentially in time to be read aloud by the human, wherein each set of information is configured to serve as a physiological micro challenge to the human when read aloud, and wherein on average the size of the information in each set of information increases over time thereby increasing the intensity of the micro challenges;
- measuring a sequence of cardiovascular (CV) responses of the human to each of the physiological micro challenges during a session, each of the CV responses associated in time with the reading aloud of one of the sets of information;
- comparing at least one of the CV responses to predefined reference CV response information;
- and
- determining, based on the comparing, if at least one of the CV responses represents a CV response deviation relative to the reference CV response information.
A system comprising:
- a computer processor;
- a computer memory in communication with the processor;
- a display in communication with the processor;
- a physiological sensor in communication with the processor,
- wherein the processor, display and sensor are configured to:
- display sets of information sequentially in time to be read aloud by the human, wherein each set of information is configured to serve as a physiological micro challenge to the human when read aloud, and wherein on average the size of the information in each set of information increases over time thereby increasing the intensity of the micro challenges;
- measure a sequence of cardiovascular (CV) responses of the human to each of the physiological micro challenges during a session, each of the CV responses associated in time with the reading aloud of one of the sets of information;
- compare at least one of the CV responses to predefined reference CV response information;
- and
- determine, based on the comparing, if at least one of the CV responses represent a CV response deviation relative to the reference CV response information.
A non-transitory computer-readable medium comprising computer readable instructions which, when executed by one or more processors, cause the performance of:
- displaying sets of information sequentially in time to be read aloud by the human, wherein each set of information is configured to serve as a physiological micro challenge to the human when read aloud, and wherein on average the size of the information in each set of information increases over time thereby increasing the intensity of the micro challenges;
- measuring a sequence of cardiovascular (CV) responses of the human to each of the physiological micro challenges during a session, each of the CV responses associated in time with the reading aloud of one of the sets of information;
- comparing at least one of the CV responses to predefined reference CV response information;
- and
- determining, based on the comparing, if at least one of the CV responses represents a CV response deviation relative to the reference CV response information.
