Definitions

  • the present invention generally relates to medical and physiological information processing systems.
  • the invention relates more specifically to a method and system for improving vascular systems in humans using biofeedback and network data communication.
  • vascular disease occurs widely in humans and is a significant cause of premature death in many human populations.
  • vascular disease is characterized by the accumulation of fatty deposits on the walls'of the arteries, causing the arterial walls to thicken and become less elastic. As a result, the flow of blood to all cells and tissues of the body is reduced.
  • Heart disease is an example of vascular disease.
  • Coronary artery disease is the leading cause of death in the adult population of the United States.
  • vascular disease in many populations can be reduced significantly.
  • One way to reduce the incidence of vascular disease is to improve identification of individuals' risks for hypertension, elevated cholesterol, obesity, diabetes, smoking, inactivity and aging.
  • Vascular disease is strongly associated with these conditions.
  • [tjools that would quantify all cardiovascular risks for use with hypertension would be a welcome and even more powerful aid than the additive technique we now have.” See S. Sheps, "Treating Hypertension," Hippocrates, v. 13 no. 11 (Dec. 1999).
  • medical evaluation and treatment of vascular disease involves using vascular studies to determine whether an individual presenting symptoms are due to vascular disease.
  • Doppler vascular studies are performed to evaluate peripheral artery disease occurring in the arms or legs. Further, the AHA Scientific Statement identified above references prior work in using duplex vascular studies of the carotid arteries to determine and correlate anatomical changes of the coronary arteries. However, Doppler vascular studies (functional studies) of the peripheral circulatory system are not presently used to evaluate risk of cardiovascular disease, and are not used to evaluate risk in asymptomatic individuals.
  • beta blockers drugs of the class known as beta blockers are commonly prescribed, but these often cause significant complications, including depression of the heart, emotional depression, impotence, effects on diabetic control, effects on exercise, etc.
  • Biofeedback techniques are known for treating certain kinds of health problems by training people to respond to signals from their own bodies. See, e.g., B. Runck, "What is Biofeedback?,” National Institute of Mental Health, Dept. of Health & Human Services Pub. No. (ADM) 83-1273. However, biofeedback is not presently applied to the treatment of vascular disease.
  • a Holter monitor may be used to gather an electrocardiogram from an individual during that person's normal activities away from a clinical setting.
  • Conventional EKG electrodes are attached to the individual at a clinic, and the electrodes are coupled to a portable data collection device that measures and stores EKG data over a specified period of time, typically 24 hours. After the data collection period, the individual returns to the clinic, where the data is downloaded into a computer for analysis, and the monitor is removed.
  • Holter monitors are not reliable, and may indicate cardiac disease only when it is severe. The same disadvantages are known with respect to treadmill stress tests.
  • Past approaches to addressing similar problems include certain online businesses.
  • “Healtheheart.com” offers online monitoring of cardiovascular diseases and online storage of clinical records, but is offered only to physicians and essentially monitors only disease conditions.
  • “Stayhealthy.com” provides certain online tools for health evaluation, but functions only as an information service.
  • “Wellmed.com” offers online services for personal health including personalized records and clinic files.
  • “Lifemasters.com” provides online monitoring of patients with chronic diseases.
  • “Dynapulse.com” provides blood pressure monitoring devices to measure cardiac function based on blood pressure readings that are uploaded over the Internet. An analysis center interprets data and provides reports. None of these approaches, however, uses biofeedback interactions, and none uses Doppler vascular data obtained from the peripheral vascular system as a global measurement tool for evaluating vascular disease.
  • the present invention comprises, in one aspect, a method for improving vascular systems in humans using biofeedback and network data communication.
  • the invention provides a method for improving diagnosis, prevention, reduction and prognosis of vascular disease by evaluating the vascular system of an individual.
  • Embodiments may involve measuring risk of vascular disease using blood pressure measurements, pulse measurements, and Doppler vascular monitoring from the peripheral vascular system, in association with biofeedback mechanisms and data communication over a network.
  • embodiments provide methods and means for preventing, reducing, diagnosing, and determining a prognosis for vascular disease.
  • a first set of clinical vascular health data from a healthcare provider and representing a vascular health condition of a patient is received at a data center server that is communicatively coupled to a public data network.
  • One or more vascular disease analysis algorithms are applied to the first set of vascular health data, to result in creating and storing an initial treatment plan for the patient.
  • a second set of vascular health data is received, after initial physician evaluation, from a monitoring device that is associated with the patient and that is communicatively coupled to the data network.
  • the second set of vascular health data include data obtained using a Doppler vascular monitor that is attached to an external location proximate to the peripheral vascular system of the patient.
  • One or more vascular analysis algorithms are applied to result in creating one or more supplementary treatment plans for the patient. At least one of the treatment plans includes a biofeedback interaction.
  • the treatment plans are provided to the patient over the data network. The foregoing steps are iteratively repeated one or more times as determined by the physician and patient, resulting in improved vascular health.
  • Embodiments are applicable to treatment of individuals who are asymptomatic or symptomatic with respect to vascular disease, hypertension, elevated cholesterol, and diabetes, and are useful in achieving stress reduction, addressing weight problems, smoking cessation, and improving personal lifestyle choices and habits.

Abstract

L'invention concerne des méthodes pour traiter des affections vasculaires et pour générer des données représentant des plans de traitement. Un serveur de centre informatique, en communication avec un réseau de données, reçoit de la part d'une personne soignante un premier ensemble de données cliniques représentant la santé vasculaire d'un patient. Un ou plusieurs algorithmes d'analyse d'affections vasculaires sont appliqués au premier ensemble de données d'état vasculaire, pour se traduire par la création et la conservation d'un plan de traitement initial pour le patient. Un deuxième ensemble de données d'état vasculaire est envoyé par un dispositif de surveillance associé au patient, ce deuxième ensemble de données comprenant des données de surveillance Doppler obtenues sur le système vasculaire périphérique du patient. Les algorithmes d'analyse sont appliqués pour établir un ou plusieurs plans de traitement supplémentaires pour le patient, un des plans au moins comprenant une interaction de feed-back biologique.
