We tried to make an estimate of how pleural effusion occur in congestive heart failure, using right atrial peressure (【RA】) and pulmonary arterial wedge pressure (【PAW】) as variables. We calculated the following equation by quoting the data in the past.【RA】>-0.02×【PAW】 13.3. We speculated that when this relationship is satisfied, pleural effusion will appear. We also studied the patients with severe congestive heart failure, dividing them into 2 groups, ie the pleural effusion group (EF) and pulmonary edema group (ED). Compared with ED, EF has a significantly higher RA (RA=6.1±1.33 mmHg in EF and 13.3±2.21mmHg in ED, mean±SE, p<0.02) and a significantly lower cardiac index (3.17±0.26l/minim2 vs 2.23±0.161/min/m2, mean± SE, p<0.01). Therefore, we thought that it was adequate to treat 【RA】 and 【PAW】 as independent variables. These equations appear to be useful in predicting the development of pleural effusion that's based in the plots of our patients on RA-PAW plane and their relationship to our equations.
