Abstract/OtherAbstract:
The purpose of this study was to determine whether improvement of left ventricular (LV) systolic function could reduce the severity or eliminate LV spontaneous echo contrast found with transthoracic echocardiography in a group of patients with advanced cardiomyopathy. A successful reduction of this by hemodynamic means might indicate an additional beneficial method of helping prevent thromboembolism in advanced cardiomyopathy. Six patients with advanced cardiomyopathy and demonstrating spontaneous echo contrast on transthoracic echocardiography were treated with acute inotropic drug infusions or aggressive medical therapy to improve LV systolic function to determine whether reduction in spontaneous contrast could be achieved by such means. A spontaneous echo contrast scoring system was devised: 0 to 4, indicating absent to severe. Six observers, unacquainted with the study plan, were blinded as to the source of the 12 pre- and post-therapy two-dimensional echocardiograms obtained and re-recorded in a random sequence, and were asked to grade the degree of spontaneous echo contrast. In all six patients, LV spontaneous echo contrast was reduced by improvement in LV systolic function (average score lowered from 2.94 to 1.25, p < 0.005). Among patients with cardiomyopathy at high risk for LV thromboembolism, as indicated by the presence of LV spontaneous echo contrast, improvement in LV systolic function may serve as an adjunct to anticoagulation or, in some cases, as a substitute when the latter is contraindicated in the prevention of thromboembolism. The results obtained suggest merit in prospective, long-term studies of a larger group of such patients.
