20090137890 | DEVICES TO MONITOR GLUCOSE LEVELS AND ISCHEMIA - The disclosure relates to systems, methods, and devices for monitoring a patient's blood and cardiac condition. Patients with diabetes oftentimes wear diabetes management equipment (e.g., a glucose monitor, an external insulin pump, or a device having dual functionality). Such patients risk silent myocardial infarction. Herein described is regular cardiac ischemia/infarction monitoring—which if not monitored can lead to (silent) myocardial infarction. Moreover herein described are combined blood monitoring functionality and cardiac condition monitoring functionality via a single device, meaning that the patient is not required to wear additional equipment. Adding this functionality to already-existing equipment is significantly less invasive than requiring a patient to wear one piece of equipment to monitor his/her blood and a second piece of equipment to monitor his/her cardiac condition. This reduction in invasiveness can lead to significantly greater patient participation and compliance, which can improve health and save the lives of many patients. | 05-28-2009 |
