Ea/Aa and E/Ea may mark fibrosis-related diastolic changes in animal models; leaves open human validation for remodeling assessment.
Which echocardiography parameters best describe diastolic dysfunction due to myocardial remodeling and fibrosis?
Specific echocardiographic parameters, including E deceleration time, IVRT, Ea/Aa ratio, and E/Ea, can effectively identify diastolic dysfunction associated with myocardial remodeling and fibrosis.
