Trial Outcomes & Findings for Molecular Mechanisms of Volume Overload-Aim 1(SCCOR in Cardiac Dysfunction and Disease) (NCT NCT01052428)

NCT ID: NCT01052428

Last Updated: 2012-11-22

Results Overview

Left Ventricular End Diastolic Volume Indexed to Body Surface Area: As an indicator of heart size, the blood volume of the heart is related to the body size. The end diastolic volume is the blood volume of the heart at the end of filling, just before contraction. The relation of heart blood volume to body size is more accurate in determining pathology because larger people require a larger heart blood volume. The values that are too high or too low indicate a diseased myocardium.

Left Ventricular End-diastolic Mass Indexed to Left Ventricular End-diastolic Volume As an indicator of heart muscle mass and heart blood volume, the mass indexed to end diastolic volume determines whether there is an adequate amount of heart muscle to pump the heart blood volume obtained from a three-dimensional analysis. The values that are too high or too low indicate a diseased myocardium.

Left Ventricular End Systolic Volume Indexed to Body Surface Area As an indicator of heart size, the blood volume of the heart is related to the body size. The end systolic volume is the blood volume of the heart at the end of contraction and is an index of the pump function of the heart. This relation to body size is more accurate in determining pathology because larger people require a larger heart blood volume. The values that are too high or too low indicate a diseased myocardium.

Systolic Longitudinal Strain. By identifying two points on the heart, the strain is the difference between the distance between these two points at the end of filling of the heart and the end of contraction divided by the length at the end of filling. Thus, the measure is like the ejection fraction, however the strain is more localized to a specified segment in the heart muscle. The higher values indicate a healthy heart.

Peak Early Filling Rate The peak early filling rate of change is calculated from the slope of the volume during the early filling of the heart with respect to time. The higher values indicate a very healthy heart muscle and lower values are indicative of a very stiff muscle.
