Stress cardiac MRI

RM Cardíaca con estrés miocárdico

This non-invasive diagnostic test yields morphological and functional information about the heart and adjacent structures. These tests can be used to diagnose various congenital and acquired conditions. During the test, the technician will ask the patient to hold their breath several times for 10-15 seconds to obtain the clearest images possible. In the vast majority of cases, intravenous contrast (gadolinium) is required to complete the study. This type of contrast rarely causes adverse reactions. In addition, a drug (adenosine) is administered intravenously to exert an effect on the heart similar to that produced during physical exercise. The images obtained at rest and after pharmacological ‘stress’ are compared to detect deficits in blood supply to the left ventricle of the heart. The test lasts approximately 45–60 minutes. The patient must not consume any foods containing caffeine (coffee, tea, chocolate, cola drinks, etc.) 24 hours before the test. It is not recommended for patients with pacemakers; patients should inform the doctor if they have metal implants and/or surgical clips.
