Clinical Trial Summary

Background: In the U.S., over 6.5 million people have heart failure. Researchers want to develop new testing methods for cardiovascular problems using magnetic resonance imaging (MRI) to improve the clinical diagnosis and management of people with heart failure. Objective: To develop and test new methods for imaging the heart and blood vessels using MRI. Eligibility: People ages 18 years and older who are having an MRI of their heart or blood vessels. Healthy volunteers are also needed. Design: Participants will be screened with a medical history. Participants will have a physical exam and blood tests. They will have an electrocardiogram (ECG) to measure the heart s electrical activity. Then they will have their scheduled MRI scan. The MRI scanner is a large, hollow tube. Participants will lie on a table that moves in and out of the tube. During the MRI, they may have contrast dye injected through an intravenous line inserted into their arm or hand. ECG may be used to monitor their heartbeat or coordinate pictures with their heartbeat. A flexible belt may be used to monitor their breathing. A finger probe may be used to track their heart rate and/or oxygenation level. Their blood pressure may be measured. Pictures may be taken of their blood vessels, heart, and lungs before, during, and after they get medicine to increase blood flow. They may lie flat and pedal a stress bicycle to increase their heart rate. Participation will last for 5 years. During that time, participants may receive a yearly survey about their health. They may be contacted for an optional follow-up MRI within 2 years of their MRI.

Clinical Trial Description

This protocol allows testing of novel research pulse sequences in investigational cardiovascular magnetic resonance imaging (MRI) and allows application of custom pulse sequences that are not market-cleared in routine clinical MRI. The purpose of this protocol is thus to develop novel research sequences and implement and test custom cardiovascular MRI pulse sequences so that the technical advances at NHLBI can be clinically implemented. This will improve the clinical diagnosis and management of patients with heart failure. ;
