摘要：

To determine the accuracy of a noninvasive system for assessing pulmonary artery wedge pressure (PAWP) in patients with chronic systolic heart failure, we simultaneously measured PAWP by right heart catheterization and by a semiautomated device (Vericor system), which uses the decrease in arterial pressure measured in a finger during a Valsalva maneuver to predict PAWP. In 30 patients with moderate to severe heart failure, noninvasive PAWP correlated strongly with invasive PAWP (r = 0.90, p <0.0001), and Vericor correctly predicted PAWP of <greater than or equal to>18 mm Hg in 91 % of patients, suggesting that this noninvasive system may be valuable in the management of heart failure.
