Method and calculations determine an individual's, or several individuals' simultaneous rates of oxygen consumption, maximum rates of oxygen consumption, heart rates, calorie expenditures, and METS (multiples of metabolic resting rate) in order to determine the amounts of work that is performed by the individual's body. A heart monitor measures the heart rate, and an accelerometer measures the acceleration of the body along one or more axes. An altimeter measures change in altitude, a glucose monitor measures glucose in tissue and blood, and thermometers, thermistors, or thermocouples measure body temperature. Data including body fat and blood pressure measurements are stored locally and transferred to a processor for calculation of the rate of physiological energy expenditure. Certain cardiovascular parameters are mathematically determined. Comparison of each axis response to the individual's moment can be used to identify the type of activity performed and the information may be used to accurately calculate total energy expenditure for each physical activity. Energy expenditure may be calculated by assigning a separate proportionality coefficient to each axis and tabulating the resulting filtered dynamic acceleration over time, or by comparison with previously predetermined expenditures for each activity type. A comparison of total energy expenditure from the current activity is compared with expenditure from a previous activity, or with a baseline expenditure rate to assess the level of current expenditure. A measure of the individual's cardio-vascular health may be obtained by monitoring the heart's responses to various types of activity and to total energy expended.

The disclosed methods, assays and kits identify biomarkers, particularly miRNA and / or protein biomarkers, for assessing the cardiovascular health of a human. In certain embodiments, methods, assays and kits, circulating miRNA and / or protein biomarkers are identified for assessing the cardiovascular health of a human.

Modular, miniaturized cardiovascular sensors, systems, methods, and wearable devices for the non-obtrusive evaluation, monitoring, and high-fidelity mapping of cardiac mechanical and electromechanical forces and central arterial blood pressure are presented herein. The sensor manufacturing process is also presented. Using accelerometers, the sensors register body-surface (preferably torso-surface) movements and vibrations generated by cardiac forces. The sensors may contain single-use or reusable components, which may be exchanged to fit different body sizes, shapes, and anatomical locations; they may be incorporated into clothing, bands, straps, and other wearable arrangements. The invention presents a practical, noninvasive solution for electromechanical mapping of the heart, which is useful for a wide range of healthcare applications, including the remote monitoring of heart failure status and the guidance of cardiac resynchronization therapy. Exercise and cardiovascular fitness tracking applications are also presented.

A composition for promoting gastrointestinal and / or cardiovascular health comprising a gelling dietary fiber and a non-gelling dietary fiber in a weight ratio of from about 5:1 to about 1:2.5; a coating component and a wetting component in a weight ratio of from about 20:1 to about 1:1; wherein a weight ratio of coating component plus wetting component to said gelling dietary fiber or said non-gelling dietary fiber is from about 25:1 to about 1:5 is disclosed. Also disclosed herein is a composition for promoting gastrointestinal and / or cardiovascular health comprising a gelling dietary fiber; a non-gelling dietary fiber; and an amount of a coating component sufficient to coat the particles of the gelling dietary fiber, such that the water-absorbing ability is reduced and the organoleptic properties of the composition are improved. Methods of promoting gastrointestinal and / or cardiovascular health are also included.

A system that continuously monitors cardiovascular health using an electrocardiography (ECG) source synchronized to an optical (PPG) source, without requiring invasive techniques or ongoing, large-scale external scanning procedures. The system includes an ECG signal source with electrodes contacting the skin, which generates a first set of information, and a mobile device having a camera which acts as a PPG signal source that generates a second set of information. Together with the mobile device's processor, configured to receive and process the first and second sets of information, from which the time differential of the heart beat pulmonary pressure wave can be calculated, continuous data related to cardiovascular health markers such as arterial stiffness can be determined. Variations of the ECG source may include a chest strap, a plug-in adaptor for the mobile device, or electrodes built into the mobile device.
