Testing a device to tell if shortness of breath is from heart failure

This trial tests if a device called Cardiostory can tell if your shortness of breath (dyspnea) is caused by heart failure or something else. It's for people who started having trouble breathing in the last week.

This trial looks at whether a new way of measuring carbon dioxide (CO2) in the blood can help doctors quickly understand why a patient is short of breath. It is for adults who come to the emergency room with trouble breathing, and it involves doing an extra analysis on a blood sample that would be taken anyway.

This study looks at how well two breathing tests work for people who have shortness of breath. You will do a breathing test and an exercise test to help doctors better understand your symptoms.

This study tests whether a CardioPulmonary Management (CPM) system device used at home is safe and can improve outcomes for people with chronic heart failure. It may help manage symptoms and reduce complications, especially for higher-risk patients.

This trial tests a small, portable device worn on the chest that measures changes in fluid levels in your lungs to help detect early signs of fluid buildup (pulmonary congestion). This could help people with heart failure avoid emergency hospital visits.

This study is looking at ways to better predict acute heart failure in people who come to the hospital with shortness of breath. If you join, researchers will use your information to develop a tool that might help doctors diagnose heart failure more quickly and accurately.
