Multimodality Imaging in the Screening, Diagnosis and Risk StratifictiON of HFpEF

Multimodality Imaging (Cardiovascular Magnetic Resonance Imaging, Echocardiography, and Nuclear Medicine Imaging) in the Screening, Diagnosis and Risk Stratification of Heart Failure With Preserved Ejection Fraction (HFpEF).

Sponsor

Chinese Academy of Medical Sciences, Fuwai Hospital

Enrollment

430 participants

Start Date

Jan 1, 2019

Study Type

OBSERVATIONAL

Conditions

Heart Failure, Diastolic

Summary

The incidence of Heart failure with preserved ejection fraction (HFpEF) in Heart failure patients increases rapidly. However, the current clinical awareness is insufficient, and the cardiac structural and functional injury are not well understood. It is difficult to recognize the subclinical changes of the cardiac in the early stage with conventional imaging techniques, and it is common to ignore the existence of the clinical alterations. This study aimed to investigate the cardiac features, early diagnosis and risk factors of HFpEF patients, based on the multi-modal (Magnetic resonance imaging- nuclear medicine imaging- echocardiography) imaging, combined with large data and artificial intelligence. This study will provide deep insights into the HFpEF derived from different causes.
