A tiny wireless sensor is now giving cardiovascular surgeons in Calgary a heads up when it comes to the ongoing care of patients who have suffered heart attacks. The CardioMEMS device, implanted in the pulmonary artery, is just 15 millimetres long and measures lung pressure, a key marker of a patient’s heart health. Physicians receive daily reports, allowing them to detect early signs of deteriorating cardiac health. Foothills Medical Centre’s Dr. Brian Clarke was the first in Western Canada to implant the sensor and has six patients that have now had the procedure. He says it reduces the amount of time someone must stay in hospital and patient care is highly individualized. Schoolteacher Michelle Kotelko, who was the first to receive the sensor, says it has dramatically improved her quality of life.
