Pulmonary Artery Pressure Monitoring Effectively Guides Management to Reduce Heart Failure Hospitalizations in Obesity

This study sought to determine the impact of therapy guided by pulmonary artery (PA) pressure monitoring in patients with heart failure (HF) and obesity. Obesity is prevalent in HF and associated with volume retention, but it complicates clinical assessment of congestion. The CardioMEMS Post Approval Study was a prospective, multicenter, open-label trial in 1,200 patients with New York Heart Association functional class III HF and prior HF hospitalization (HFH) within 12 months. Patients with a body mass index (BMI) >35 kg/m2 were required to have a chest circumference
