Heart failure is a major health concern worldwide and is especially impactful in the Guadeloupe region, which has a high rate of heart failure deaths. This study evaluates the feasibility of robotic remote echocardiography integrated into a telemedicine system to improve heart failure management in the Guadeloupe archipelago, specifically comparing measurements of left ventricular ejection fraction (LVEF) between standard in-person echocardiography and two-dimensional remote echocardiography. Participants will undergo two types of echocardiography: in situ echocardiography performed by a cardiologist at Marie-Galante Hospital, and remote echocardiography conducted by a cardiologist from a private practice in Guadeloupe, with a nurse present at the patient's location. The study uses a randomized crossover design where patients receive both procedures in varying order. Cardiologists alternate between performing remote and in-person echocardiography to account for operator differences. Participants are involved in visits that include blood sampling and 24-hour ECG Holter monitoring. Researchers will measure the agreement of LVEF results between the two echocardiography techniques at the second visit, two weeks after inclusion. The study focuses on improving access to specialized heart failure care in a geographically isolated area and includes monitoring to ensure patient safety and data accuracy throughout the study period.
