A recent study on stable, hypoxemic, COLD patients in which ANP was stimulated by LBPP demonstrated that in these individuals elevation of ANP does not exert a "normal" suppressing effect on the PRA-PA axis. Accordingly, we exercised ten comparable COLD patients, another maneuver known to stimulate ANP and to elicit cardiorespiratory responses substantially different from those observed with LBPP. Patients were studied breathing room air and on 40 percent O2 to determine whether the level of oxygenation would modify ANP secretion. Basal levels of ANP on room air were markedly elevated above controls (269 +/- 65 SE vs 70 +/- 20 pg/ml, p less than 0.05); PRA (13.0 +/- 5.4 ng/ml/90 min) and PA (8.6 +/- 3.5 ng/100 ml) were elevated (greater than 2 SD over control levels of 8.1 +/- 1.3 and 2.6 +/- 0.7) in 6/10 and 2/10 patients, respectively. During exercise while breathing O2, only ANP increased; PRA and PA remained unchanged when breathing air and O2. Comprehensive statistical analyses failed to demonstrate a negative relationship between ANP and PRA or ANP and PA. We conclude that in patients with advanced COLD, ANP response to moderate exercise is significantly affected by correction of hypoxemia. This effect may be mediated through changes in airway resistance and consequently cardiac filling pressure.
