140This study will look at how a single dose of study medication (tolvaptan) versus an inactive sugar pill (placebo) effect pressures in the heart in patients with congestive heart failure. Higher than normal pressures can be related to symptoms of heart failure (shortness of breath, fatigue, etc.).
