Comparison of noninvasive measures of contractility in dilated cardiomyopathy. Review uri icon

Overview

abstract

  • Left ventricular performance is usually quantified by ejection phase indices such as ejection fraction, cardiac output, and fractional shortening. The load-dependence of these measures may result in inaccurate estimation of intrinsic myocardial contractility in states of chronic pressure or volume overload. End-systolic and stress-shortening relations have been proposed as measures of contractile state insofar as they are theoretically independent of preload and incorporate afterload. This article examines the behavior of these relations in response to changes in loading conditions and contractile state and reviews their application utilizing noninvasive methodology, particularly in the setting of dilated cardiomyopathy.
