- High output heart failure
- Pericardial disease
- Clinically significant chronic lung disease in the opinion of the investigators
- Anemia (hemoglobin \<12 gm/dL in women and \<13 gm/dL in men)

- Pregnant women
- Any other disorders or problems that would interfere with the ability to participate safely in the study (e.g. psychiatric disorder or substance abuse)
