Do LV diastolic function and longitudinal strain provide incremental prognostic value for identifying older adults at risk for HF hospitalization or death?
Heart failure with preserved ejection fraction is the dominant form of prevalent HF in older adults, and advanced echocardiographic measures like diastolic function and longitudinal strain improve risk prediction for adverse clinical outcomes.
The majority of older adults in the community are at risk for HF (Stages A or B), appreciably more compared with previous reports in younger community-based samples. LV ejection fraction is robustly preserved in at least two-thirds of older adults with prevalent HF (Stage C), highlighting the burden of HF with preserved LV ejection fraction in the elderly. LV diastolic function and longitudinal strain provide incremental prognostic value beyond conventional measures of LV structure and LV ejection fraction in identifying persons at risk for HF hospitalization or death.
