Abstract
The prevalence of heart failure continues to increase throughout the world. This rise in diagnoses corresponds with high rates of hospitalization, patient and caregiver fatigue, and ever-increasing economic costs. While numerous investigations have been undertaken in the past looking into remote monitoring or telemedicine strategies, they were unable to show an improvement in clinical outcomes with use. Invasive hemodynamic monitoring in the ambulatory setting has been an area of focus for the last several decades as a possible proactive strategy aiding in the evaluation and management of the heart failure population. Several large, randomized trials have not only shown the safety of a pulmonary artery pressure sensor in the heart failure population but have also confirmed the efficacy of pulmonary artery pressure-guided heart failure management in reducing rates of heart failure hospitalizations. Additional novel implantable devices are in various stages of development and clinical investigation and aim to further help aid in the management of this complex patient population. Future strategies are emerging and include the increased development of wearable devices as well as novel technologies to assess hemodynamics and volume status.
