Outcomes in Hospitalization in Patients with Heart Failure Undergoing Remote Pulmonary Artery Pressure Monitoring: A Systematic Review and Meta-Analysis of Major Trials

Heart failure is a leading global pandemic and a cause of economic burden. Although, treatments exist to help symptomatic alleviation, patient compliance and monitoring is the basis of ensuring efficacy. With devices that allow for remote wireless PA pressure monitoring such as CardioMEMS, the inconsistency in patient reporting and factors such as symptoms and hospitalizations can be reduced. A systematic review and meta-analysis utilizing the MEDLINE, Cochrane, and Scopus database was performed to identify randomized and non-randomized clinical trials evaluating baseline characteristics and hospitalizations. Five trials for the systematic review and 2 trials for the meta-analysis meeting the inclusion and exclusion criteria were included. Baseline characteristics included an average age of 64.6 years, male predominance, mean BMI of 29.6, predominance of HFrEF, hypertension the most prevalent comorbidity, and a mean PA pressure of 27.2 mm Hg. The follow-up periods ranged from 90 days to 12 months. There was a total of 64 adverse events, mostly non-serious. Patients who underwent remote PA monitoring were less likely to be hospitalized compared with patients who did not (Odds Ratio: 0.52; 95% Confidence Interval 0.39, 0.69). Remote PA pressure monitoring allows for reduced hospitalizations. With the recent and now resurging SARS-CoV-2 pandemic, devices such as CardioMEMS can allow for heart failure patients to be managed from home to not only reduce hospitalizations but for symptom prevention and management.
