Heart Failure With Preserved Ejection Fraction: Will Cardiac Magnetic Imaging Impact on Diagnosis, Treatment, and...

Area of Science:

• Cardiology
• Medical Imaging
• Diagnostic Accuracy

Background:

• Volume overload symptoms are often inaccurately equated to heart failure (HF).
• HF classification traditionally relies on left ventricular ejection fraction (LVEF) into HF with preserved LVEF (HFpEF) and HF with reduced LVEF (HFrEF).
• Echocardiography has been the primary tool for assessing LVEF and guiding HF management.

Purpose of the Study:

• To investigate the evolving role of echocardiography in HF diagnosis.
• To explore the potential of cardiac magnetic resonance (CMR) as a complementary or primary diagnostic tool for HFpEF.
• To assess if CMR can enhance diagnostic precision and improve outcomes in HFpEF.

Main Methods:

• Review of current clinical practices in HF diagnosis.
• Analysis of the diagnostic capabilities of echocardiography and CMR in HF subtypes.
• Examination of emerging data supporting a third HF subtype and its assessment.

Main Results:

• Echocardiography's dominant role in HF assessment may be shifting.
• CMR shows potential for refining understanding and diagnostic accuracy in HFpEF.
• The study posits a potential increase in CMR's profile for HFpEF evaluation.

Conclusions:

• Accurate HF diagnosis requires precise differentiation beyond simple LVEF metrics.
• CMR may offer superior insights into cardiac pathology compared to echocardiography alone for HFpEF.
• Further research into CMR's role is warranted to optimize HFpEF management and patient outcomes.
