HealthStat International has launched a portable home device A-Pulse CASPal to measure blood pressure from a person’s aorta. This reading is a better indicator of the risk of heart attacks and strokes than one taken the conventional way from the arm. The device offers a non-invasive way of getting a reading of the blood pressure from the aorta, the main vessel which carries oxygenated blood out of the heart to the rest of the body.
