Devices on the Edge
A Gentler Heart Test

“Can you walk up a flight of stairs?” a cardiologist asks a chronic heart-failure patient in order to assess her heart and lung function. Then the doctor orders what is sometimes called a stress test, monitoring her heart while she takes a six-minute walk on a treadmill. This test can be very strenuous for some people; shortness of breath may have been the very symptom that brought them to the cardiologist’s office.
A new device, the Shape-HF Cardiopulmonary Testing System, from the St. Paul medical device company Shape Medical Systems, Inc., helps physicians determine a patient’s cardiopulmonary health in a less taxing way.
