The influence of iodine contrast administration on cardiac parameters during coronary CT angiography.

Research output: Unpublished contribution to conferencePoster

Abstract

In coronary CT angiography (CCTA), contrast administration has an impact on cardiac output and stroke volume resulting in a significant increase of both parameters. A significant change in heart rate could not be observed in our study.
A weak, but significant, negative correlation between cardiac output and CT values in the ascending aorta was found. This means that a higher cardiac output results in a lower contrast density in the aorta and the coronary arteries. There was no proven effect of heart rate or stroke volume on the CT values.
Cardiac output can be assessed prior to a CCTA examination using a physiological monitor and therefore could be potentially used to optimize contrast administration in terms of contrast concentration in order to achieve a constant enhancement in the coronary arteries.
