摘要
Twenty-two patients(19 men) with heart failure(16 ischemic, 6 dilated cardiom yopathy; mean age of 67±6 years) in New York Heart Association classes I(2 pati ents), II(18 patients), and III(2 patients) under optimal therapy were strictly monitored after carvedilol supplementation. The Tei index decreased significantl y from 0.87±0.17 to 0.53±0.29(p< 0.03). Conversely, the ejection fraction and transmitral Doppler flow analysis did not show significant improvement, despite a trend toward the amelioration of the ejection fraction, the E-/A-wave ratio, and atrial contribution. The Tei index could represent an earlier marker to eva luate drug-induced left ventricular function improvement in patients with heart failure and could represent a more sensitive tool to monitor left ventricular f unction during drug interventions.
