Evaluating the Influence of Apnea on Heart Function With Strain Analysis and Measurement of Fibrosis Derived From T1-mapping Using Cardiac Magnetic Resonance Imaging (MRI).

University Hospital, Bonn·interventional·Posted Oct 31, 2014·Updated Feb 7, 2018

In Brief

A clinical study evaluating magnetic resonance imaging (MRI) for Physiological Changes in Deliberate Apnea. Completed, enrolled 17 participants.

Detailed Summary

Former studies revealed a distinct pattern of changes in circulation during deliberate apnea. Blood pressure rises significantly often accompanied by bradycardia. Further studies confirmed a massive increase of total vascular resistance as it also happens in shock to maintain perfusion of heart, lung and brain. This study is to determine the exact alterations of the cardiac function during this reaction, show the redistribution of blood volume in apnea and evaluate possible longterm effects on the central nervous system caused by repeated apnea via magnetic resonance imaging.
