Ambulatory Heart Failure Monitoring: A Systemic Review

Heart failure (HF) is one of the leading causes of morbidity and mortality and has a large effect on the country's economy. Although there have been major advances in HF monitoring, including more advanced pharmacological management and device-based therapy, HF-related mortality remains high. It is important to monitor HF so that HF-related hospitalization and mortality can be prevented. Due to the lower sensitivity of clinical features and biochemical markers, as well as the failure of telemonitoring in early detection of HF, more advanced techniques have been sought to more accurately predict impending HF, in order to address timely pharmacological management and prevent heart failure hospitalization (HFH). Device-based therapy has passed through various stages and culminated in the recently introduced CardioMEMS^TM (St. Jude Medical, Inc., Saint Paul, Minnesota). CardioMEMS^TM is a wireless pulmonary artery pressure (PAP) monitoring device, which continuously monitors PAP and transmits data to a healthcare provider. It rapidly identifies changes in intracardiac pressure and allows timely pharmacological management. CardioMEMS^TM showed a higher reduction of HFH compared to any other devices.
