Trial Parameters
Brief Summary
The purpose of this study is to investigate whether acute stress can precipitate congestive heart failure (CHF) exacerbation in patients with CHF.
Eligibility Criteria
Inclusion Criteria: -Heart failure patients over 18 who have or will be receiving a Cardiomems implanted PAP monitor. Exclusion Criteria: * Patients who are unable to perform EMA or laboratory assessments due to cognitive, visual, language, or other disabilities will be excluded. * Patients with Class IV heart failure will also be excluded, as they are already maximally decompensated, and a ceiling/floor effect would preclude effects of stress. * Patients with conditions other than heart failure that affect PA pressures (e.g. dialysis). * Patients with physical conditions that interfere with study participation. * Patients non-compliant with their PAP monitoring. * Patients with chronic opioid use will be excluded.
