Specialized nurses have a growing role in diagnostics and follow-up of outpatient HF patients, and adding ultrasound diagnostics to the nurses consultations may improve care. In heart failure patients the use of ultrasound as a tool for assessing volume status and guidance of diuretic therapy are promising. Aim of the study is to evaluate the feasibility and reliability of echocardiographic acquisitions by heart failure nurses to assess cardiac function indices and assess volume status in outpatient heart failure clinics combined with a telemedicine approach for near real-time interpretation of the recordings by a cardiologist specialized in echocardiography and heart failure at a remote location.
