Definitions
- CPE cardiogenic pulmonary edema
- NCPE non-cardiogenic pulmonary edema
- NCPE has a slow or difficult recovery due to impairment of the alveolar-capillary epithelial barrier properties and failure of repair due to initial insult.
- PCWP pulmonary capillary wedge pressure
- PAOP has been recognized as a potential marker.
- use of pulmonary catheters to measure PCWP is controversial as the technique is invasive, offers unclear or limited benefits, and carries the burden of increased risk of infection, thrombosis and patient discomfort.
- Laboratory data including markers such as brain natriuretic peptide (BNP) , NT-proBNP, and the troponins are often elevated in patients with acute CPE. Thus, an absence of elevation of these markers can be used to rule out CPE.
- Radiologic data such as the vascular pedicle width
- VPW has been shown to accurately differentiate CPE from NCPE, with a higher VPW (e.g., greater than 70mm) corresponding to CPE. However, the VPW is not routinely measured. Routine
- Echocardiographic markers such as ejection fraction (EF%) or the ratio of mitral peak velocity of early filling to early diastolic mitral annular velocity (e/E' ratio) can be used to differentiate CPE from NCPE.
- markers may have limited benefit late in the disease course, as patients with NCPE can develop concomitant CPE.
- Patient history from charting data can also provide key
- NCPE may also have great prognostic value and may help care providers better assess the chance of edema progression or recovery.
- Identifying acute respiratory distress syndrome (ARDS) one type of NCPE, can aid in the patient prognosis and provide necessary context for care providers to better manage the patient's condition.
- ARDS acute respiratory distress syndrome
- NCPE however, they have limited applicability. Obtaining the markers may be invasive, not routinely available, not sensitive or not integrated with other markers. Further, risk of CPE or NCPE is not automatically calculated and none of the clinical markers allows for the further differentiation among causes of NCPE or identification of ARDS .
