What research recommendation did the committee make regarding the use of cardiac MRI in HF patients?
The committee noted that during scoping for the guideline, it was thought that the amyloidosis question would complete the diagnostic picture, sitting alongside general recommendations on cardiac MRI imaging for HF. However, as no evidence was identified for the effectiveness of cardiac MRI in improving outcomes for HF patients, the committee decided that it would not be necessary for the guideline to specifically consider secondary imaging for a relatively narrow subset of patients with HFPEF. The committee noted that future research addressing the research recommendation including the OUTSMART 255 trial should answer the question on whether cardiac MRI in HF patients is clinically and cost- effective.
